"There's many reasons we went with this turbo, one of them is, we're lazy"..... It's like you spoke to my soul.
no need to re-invent the wheel sometimes ;)
There are Gearheads and then there is MotoIQ…absolutely appreciate this Channel and Mr. Kojima 🙏
Yes, but Backpressure is Very harmful 4 Any engine's endurance !!! ! !!!
Praying does squat.
The stock positioned turbo suffers from heat just the same as a custom position turbo there are only a few inches in position
@@Adl-pk4hg Yes, But many Times even Less than inches matters !!! ;-)
“You Don’t Need A Damn X!” is a series I think a lot of people need to see. Lots of people out there doing things or installing things on their car that they think they NEED but actually really don’t.
Yeah forums have people thinking there's only one way to do something. Found that out when i had a st180 celica. A few years after i let the celica go i found a whole chunk of info for the things i was asking in those forums. Granted new methods are found over time but it was complete obstinance from multiple forum ppl.
Only thing I plan on “overbuilding” on my 4g64 build for my eclipse is pretty much the engine itself. My engine should theoretically be good for upwards of 800hp (im not actually 100% on that, at least the pistons and rods will be) but I plan on making 300-400whp. Pretty much gonna be using an evo 8 td05 and try and replicate what Mitsubishi would have done if they turbocharged my model with some functional upgrades and modernization sprinkled in
Yes just like control arms and such. If you aren’t tracking your car. You don’t need aftermarket end links and control arms etc.
Can we just take a moment to appreciate this guys passion and dedication to Subaru Motorsport
I’ve watched a few motoiq videos and I’ve learnt profound amounts of information every time. This channel is highly underrated! Thank you so much everyone involved in producing these gems for FREE!
Listening to this gives me Bob Ross vibes in the best way possible. Very calm and relaxing, yet very "to the point".
this guy is the Einstein of the performance car world. you explain everything very well. this is my favorite youtube channel. ive learned so much already. 😊😊
Honestly the more I listen to him the less credit he has. He even has a video saying Toyota 5a cranks can't manage over 200hp. We've been racing those at 10.3 seconds and 660HP for years now. Also, a larger compressor wheel will be needed if you want over 600hp. It's just physics.
@@funpeoplearoundtheworld7027 try doing something other than running for 10 seconds and your crank won't manage, don't believe me, the guys at MRP agree with me. Do one noncompetitive fun track day in your 660 hp stock crank car, how much do you want to bet it won't be running at the end of the day?
Great videos, especially for someone looking to enter the automotive field 10/10 its always a treat to have the ability to communicate with a channel that values replying to comments that are worth it and makes for a much tighter community. Not to even mention the digestible text book level of information that this channel brings and the host always has a smile and seems to be a really cool guy.
mike AND subaru stuff? you know its gonna be a good day 😁
Im getting ready and saving up to build an early Impreza early 00's. And I needed to learn all of this to choose an appropriate turbo for my project thank you guys
I have moved on from Subaru to a different platform. However I still love watching your videos as so many of the same principals apply to tuning any car. Thanks for the in depth analysis you do.
So many good points about compressor and turbine efficiency, and how compressor efficiency not only heats the charge air more but still takes more energy from the turbine/exhaust that then adds backpressure.
I can listen to this guy all day. His humble delivery but highly knowledgeable approach to car builds is a great combination
The amount of information just flowing through this guys brain. Absolutely awe-inspiring!
These videos are so good. It's such a great resource for Subie fans - or even anyone learning about car engineering in general.
Weeelll, the Subaruba shoud be Twin Turbo, or at least rear mounted symetrical Turbo, everything else is just a waste of time.
So many people do unnecessary mods because of forum posts and Facebook advice. Great video.
I'm very new to the WRX STI scene and I immediately noticed that it seems people don't know when to stop adding so much unnecessary crap to the car and doing performance mods for all the supposed track days that everyone claims to be doing. I find it odd.
I haven’t seen wire twist pliers used by anyone else than my father in the past 30 years. It was a good surprise.
Seeing these little things by the real professional is comforting
Best videos to fall asleep on TH-cam - in a good way. Love listening to Kojima and his knowledge
No sleeping while you're learning! 😁
I bought the 2.4in inlet 'Gen 1' version of this exact turbo secondhand about a year ago. Had it rebuilt by a reputable builder. Been hoarding parts to add it to my car in the next year or so.
Thank you guys so much for sharing what these turbos are capable of! You can really get lost in the sea (literally smh, IYKYK) of stock location, hybrid, big turbo options for the EJ platform. Most of them don't give much differing spec info, other than lb/min or what size the exducer may measure out to be, etc etc. You're always wondering what the peak output is, and the power band can be a complete question mark. NOT TO MENTION - everybody usually just copycats everyone else and gets the same turbo as the next guy.
Just seeing that this can hit just over 500whp/tq on a dyno without some crazy ass setup is amazing. Shout out to MotoiQ for making this video for the Boxer boys! 🙏🏾✊🏾🤙🏾
How did your build go bro? Any info would be appreciated I am considering finding a gen 1 as well
Great video, love how technical you are!🛠
Thank you sincerely for this video. It made everything and mostly all my questions answered. Im currently running a TD05-20g turbo and built intternals. 400whp setup currently and want to go up to 550-650 range and thought for sure i had to go rotated to achieve it. Would love to chat with yall for a min to get a few suggestions. Great videos as always and thanks so much for doing what you do
I would love to have a similar daily set up like yours! It’s a beautiful build.
Excellent and spot on as usual. Thanks MotoIQ and Mr. Kojima.
Thank you for this valuable information..I'm in the process of an engine build and have been debating turbo location, this pretty much helps me decide, stock location it is.
I want my next short block built by Mike!
Dude is a freakin legend!
impressive dyno numbers + the fact you are utilizing the stock location.
Thank you for the video and all the information and knowledge. You're the man Mike.
I was running the older version of this turbo with the 55mm/76mm compressor wheel as opposed to the newer 58/76mm compressor wheel and was very impressed with the driveability characteristics. On my VA 2.5 it made 520bhp/550lbft on pump fuel and 560bhp/600lbft on a meth mix.
The older version was 55mm. Your gas must be really good in your area. 93 octane?
@@motoiq Apologies, that was a typo. I’m in the UK and I think our 99 octane is equivalent to your 93. This is crank horsepower, not whp.
What's the size of the turbine wheel?
Turban = headwear
Tur BIne = Compressor.
Seriously tho I love you guys.
That guy is like Mr. Miyagi....very wise and capable, but also super kind and friendly
Good information Mike, really like your videos.
Mike and his knowledge man. I've learned so much that I'm ready to throw out my impreza's shortblock and slap those heads on a wrx shortblock 😅
The antirotation stop is very clever!
I could listen to you talk subys all damn night. Thank you sir.
This is fascinating as someone with a Garrett, you can rotate the housing itself, and even take it a step further by getting a V-band style mount which adds even more rotation capabilities. I understand vband means more fabwork, but it's a quality of life improvement that's worth it tbh.
The up pipe is different and sometimes the headers on a rotated mount, the turbo is rotated and forward of stock.
Anything and everything to get to the meat of fun in car building ASAP: fuel mapping/trim tuning and programming with a live engine
This car reminds me of the early 2000s and the late 90s. Cars built for daily drive and like the most muscle for your commute or stress relieving drives! Then when you wanna go out and race you get into your street racer and go to the drags, but that sti isn't what you take to the races unless you do mountain runs this car almost seems perfect
Amazing in depth video again! Suggestion for a video going over Subaru’s stock piston material and going over ringland failure how the stock pistons are cast hypereutectic aluminum-silicon (Al-Si) alloy and the percentage of silicon in Subaru pistons vs other manufacturers that also use this material and how much of an advantage well made forged pistons (and rods) are.
Hypereutectic alloys have more silicon than the saturation limit of aluminum in solid solution which is typically 16-18 percent. The other problem is the Subaru has a really high first ring land for emissions reasons, combine the two and you have a fragile piston.
Thank for your reply 🙏🏽👏🏽
My best friend just got a hawk eye STI, and i think all we will do to it is a front mount IC, a perrin intake tube and keeo the aftermarket catback that came with it.
The best knowledge around love your videos and keep it coming pls.
Neat! I ran meth and FP Green drop in turbo back in the day on my 04STi. These were UTEC days and then on to RomRaider.
That was a long time ago!
Such good information. Anytime I see Mr Kojima I all ears
Somehow I imagine Bobby Lee's father looked like Mike 😂
Love the channel, love Mike's approach explaining car stuff 👏
It’s not a fact that you need it, it’s the fact that you want it. It looks cool and you can fit s bigger turbo
i just found this guy holy shit this guy is awsome his knowledge with his Stupid chill tone Stay awsome man!
I'm pushing 450hp on my WRX the way it came other than a 20G turbo and been running it like that for 4 years and had no problem. I tried the front mount intercooler and I developed major turbo lag so I just went back to the top mount intercooler upgrade and everything is great still. I agree with you on the stock location for the turbo. Well said in detail.
What year wrx do you own? Thanks!
To make 450 hp you need a lot more than a 20G!
car guys always be fudging some HP numbers hahaha@@motoiq
I love the way the car looks
I am not a fan of those wheels(I know I'm in the minority here), but on this car they look great! NOt a fan of silver... anything...
Love my blouch dom 5.0xtr made 510whp on only 25 psi with a top mount intercooler, there’s a lot more power in that turbo too.
interesting take. I have a version 4 sti short block in my 1997 gc8 i'm building right now. Ej22 semi closed deck with ej20 crank but I'm gunna slap on the new G30 and see how she fairs. I'm going externally gated is why I went rotated. Also, because I only really take her on the freeway
I love that you are working to debunk a lot of the crap out there about builds in our Subaru. Take my FXT(04) build as a example. FP Green, grimmspeed TMIC, (all supporting mods) stock locations.. 425whp on a hub dyno, 400lb torque, absolutely no issues at all. I could with ease toss a bigger turbo in (fp black) and push up to 500 and still be well inside the stock location/TMIC's capabilities.
GREAT breakdown Mike! Wish this video was out before I started my rotated setup I could have saved some money and I'm only shooting for 500whp.
For 520 and below, you can't beat this approach. I think with a bigger intake filter, instead of the CARB approved Cobb one and perhaps a bigger intercooler, it would have make perhaps 540 whp. When we dynoed it was a 103 degree day and that killed the power too.
worth it. better spool and flow. looks cool
Yea, I had to cut back due to costs of going rotated. So i went with a BCP X500R. The only thing holding me back now is fueling.
@@cosworthstisedan
I feel you man, it didn't help my case that I wanted the best. ETS titanium kit, KillerB headers, Process West reverse mani, IAG stg 2.5 closed deck block, ETS titanium FMIC kit and the list goes on and on and on....lol
Let's not include the total labor costs of a proper shop doing the build as well. (oy vey)
@gr8td3cepti0n3 yea man that cost adds up & it does it quickly.
I was waiting for this. Thanks!
I loved the comparison to the corvette power band at the end, Subis are really slept on. Sure they’re not the cheapest cars to build, but having an AWD car with that power lvl and handling ability, not a whole lot tops that. Great video! I’m convinced now - going with a stock location build
It's crazy because I have owned a base C6 and have dreamed about getting a Z06. I also own a 05 wrx wagon and hearing that this turbo could very well compete with my dream C6 is crazy. I love both cars, but it's crazy to see what this little fiesty 2.0 liter can do. Of course it won't be to the extent of the 2.5 IAG that's on the STI in this video but the idea that I can build my wagon to perform engine wise better than an LS7 is crazy.
I don't think Subaru is that slept on, a WRX or STI of any year and condition always seems to cost more than I thought
If u want a big hp car that's awd, reliable and great handling get an evo.
Subaru's aren't reliable until u pour a ton of cash in them
@@juddy953 I'd highly disagree, Evos are harder to come by and are becoming sparse in available parts. Reliable cars are owned by good owners.
I would build 500 cars before I built another Subaru.
Awesome informative video, i can hear this man talk about cars and efficiency for hours 😂
dang....makes me wanna sell my E90 M3 and buy a STI. Your car looks amazing! Great Video Sir! ✌
Calvo motorsports has been reaming out precision turbos here recently. I hope they arent as bad as calvo claims bc this turbo setup seems perfect for me in stock location...
We ran the 55mm version for years with no issues and since we run even lower boost with this one, we don't see any reason why it wouldent be reliable. The amount of power, the wide powerband, and the ease of installation make this hard to beat.
If you need a fun primer on boosted engines, I would suggest reading "The Secret Horsepower Race" by Calum E. Douglas: it follows the engineering race between the Allies and the Axis on the Western Front from the late 1930's to the end of WW2.
A lot of what we now take for obvious in boosted engines was developed in those years at massive expense and record time. Some things, like throttle bodies water/methanol injection or compressor entry fuel injection at high boost have yet to reach the point aero piston engines were at when jets took over.
It helped me get some of the the details of Kojima's teachings.
Does it talk about liquid vs air cooling and the lack of good fuel and materials on the Axis side?
@@motoiq extensively, the effects of different fuels on valves, main bearing wear, alternative quality metals in critical parts and the vast engineering resources the Germans wasted trying to solve this. Meanwhile the allies could just add an extra 2% zinc and call it a day.
There’s also a lot about engine management, a subject you have no interest in ;) - Turbo surge was a major issue.
The campaign against knock was hard
Also you can eliminate 3 feet of intake pipe by running a side bottom intake vertical intercooler with a backwards facing center upper exit
Didn't want to re engineer my AC, Lazy!
id love to see a video like this when it comes to the intake manifolds
We know the process west works really good!
@motoiq i have been on the fence about doing an intake swap to an oem long runner or aftermarket. I just really wanna see the pros and cons, and would it be worth the labor and cost for this possible upgrade
If your car is stockish, probably not worth the money.
A huge reason that people go rotated is the so that they aren’t limited by the turbo inlet going under the manifold and the limitation of the turbine housing AR. Sure you made 500 ftlbs but it fell all the way to 320 by 7600. With a bigger AR you can keep that torque up for way longer.
With that being said, It all depends on what kind of build you’re going for. This is still a badass build for sure
This turbo combination makes more power and more area under the curve than most equivalent-sized rotated mount turbos that we have tested which frankly surprised us. The turbo also made the power with relatively little boost, only 18 psi at high rpm. We think the tiny filter of the CARB legal Cobb airbox choked out a lot of power as well. For going for any more power than this, rotated mount is the way to go for sure but even this power level is approaching the end of the sweet spot for these engines when it comes to durability.
lets be honest.. making power with a subaru is stupid.. buy a real engine if you need more than 400hp.
Did you see the part on how this engine breaks off FBO LS7's? Like 50% more area under the power curve and more peak power.
@@TurboVisBitsPower is subjective, not everyone wants to drive their car in a straight line and then park it for the rest of the year
With the rotated as you say you'll keep power at top... but laggy at the bottom; not a good for a street car.
It’s very simple: I see Subaru MotoIQ video, I click.
Favorite thing about the pre 2006 STI's is the 35:65 powersplit, everything 2006 and forward understeers more. We could have also gotten the EJ207 with twinscroll from factory like japan but emissions.
Not getting the EJ207 had nothing to do with emissions. Subarus assumed the US market wanted more torque so they developed the 257. With longer gearing.
I've driven JDM EJ207 sti cars in Canada. They aren't suited for long north American roads. The gear ratios on those cars are tighter. (Not fun on the highway). The 207 needs to be rev'd out to feel the power.
The low end torque on the 257 is definitely noticable.
A lot of people don't know that about the center diff in the GD's.
In 2006 they added a mechanical lsd component to the center diff. And you're right, they push harder
I had a 2005 with 400whp and a great suspension. Stabbing the throttle at the epax always rotated the car. I really miss that thing. 😊
2004 specifically is even more real wheel bias ;)
@@JDMRSX509 same as 05
Wrong doesn’t understeer more at all. They have very similar characteristics and Infact the 06 got some other updates to the stiffening of the chassis which made it turn in better
Love this channel
These videos are so great
I have a Billet chra on a sti stock turbo with vf52 intake housing fits right in with no rubbing. I keep the same specs for intake and exhaust turbine wheels . I have 2014 wrx base, and it's a good cheap upgrade.
Wait, stock wheels but you changed the center section?
@MotorSwapDan Yes, the vf48 and vf52 have the same specs , even the exhaust side and intake. The only difference is that the angle of the intake housing is also the boost line. The vf48 holds more boost at mid to high rpm. The vf52 holds up to 5000 rpm and then trappers off.
I swapped in a ver7 EJ207 with a stock location GT3076r, biggest TMIC (forgot brand) that would fit under the hood and 100% e85 back in 2009. Made 500whp. Upgraded axles, ver7 JDM 6spd, BBK up front with brembos in year. Miss that thing. The one thing people kept saying was to get a roted set up and FMIC. I hated both those "upgrades". Made the street drivabily unbearable with lag. Shit, I was running the stock air box at 350whp. Certain upgrades sounds cool, are expensive, and sometimes not needed for what you're trying to accomplish. Research before recommendations.
I wish I'd have you as my mechanic ! ❤❤❤
Great insights! I am also keeping stock location turbo.
@MotoIQ interested to know why you opted for this precision turbo instead of a stock location Borg Warner EFR7163 that you raved about in your other video?
The BW is a great turbo but it isnt a direct drop in. I wanted to try the Precision out. I also wanted it to look sort of stock because my daughter has been pulled over by cops before and hassled. Then I put on the Process West intake manifold to test it and there went the stock look. I might sand off the milling marks and paint it the OEM wrinkle red later.
It's hard to agree with a lot of TH-cam videos but you sir are completely right. I ruined my VA with a 6466, ya it's 740-820hp depending on Dyno brand but I hate driving it. I had to purchase a VB as my daily. Moving forward I'm not going HUGE setup for my daily. God awful
Also one mute point that I forgot to mention. Getting to 500hp fairly reasonably affordable but getting closer to 800hp, between the car and all of the supporting mods nearly $100k, lost count.
I used to be like that too, when I was young building kind of the street kind of stuff. As I got older, I found that more flexible engines were funner to drive on a daily basis.
Very nice video :) The "it feels like it has lag but on the dyno it's making good power by 4000rpm" sounds like the general impression I've always had from Precision turbos versus some other brands. It's like they dyno well, and have a solid boost threshold if you give them enough time to build the boost - but the transient response (time to reach the boost it CAN make at whatever given rpm) seem to be lazier than other things that may make similar power. Almost like the dead opposite of what Borg Warner EFR turbos are like, where the dyno plots don't really set the world on fire - but driving them and the advantage to low inertia wheels etc start making sense.
It's typical Subaru turbo far from the exhaust ports and long intake tract lag. For a Subaru its pretty responsive.
@@motoiq Ah yeah there is that too haha. Often wondered how hard and how much different a pair of smaller divided housing turbos on an EJ would be like - one cylinder per scroll to attempt to negate bad pulse collisions etc.
Typically twin turbos on a 4 cylinder are not as efficient. Subaru tried them for a while then scrapped that. Twin scrolls work good. However even with a twin scroll the turbo placement would be less than ideal on an EJ. Our twin scroll stroker long rod 205 is almost ready to tune. One thing I would like to try on someone else car is the Killer B low mount turbo kit.
@@motoiq yeah funny you say that, I agree twins generally don't make sense on a 4cyl and divided housings less relevant on an EJ because a lot of the point of divided housings is the reduced volume so they build drive pressure quick and also clear quick so you kinda get sharp response without necessarily ending up with ridiculous EMAP. With an EJ you can't have the short runners that are kinda needed to make it work.
Same with twins on an inline 4 don't make sense because you need bigger volume manifolds and plumbing which defeats the purpose of twins, where you end up neatly packaging the turbos close to the head and you are making much better use of the exhaust energy (so V6s are basically build for this). My thought was a boxer actually is probably a lot better suited to twins if you divide the pulses than any other 4cyl because things are quite quite different to the rules you'd follow with other 4s as they are a bit more like a V6 config in that regard, aside from the pulse events being uneven which is why I threw the divided housing idea in there
The other thing is where is it all going to fit. Subaru engine compartments are tight to begin with.
Anyone know the precision part number for this turbo? I would also be interested in the "smaller" turbo he references. Ive run the old sc63 on a 2.6l mistu engine and loved it.
Great content and info! (From Australia)
What are your thoughts on the Blouch Turbos that are stock located? I have the Blouch Dom 3.5 xtr great all round turbo.
Made 345kw atw (approx 460whp) @ 21 pound. Pretty much daily it, great streeter (in a forester XT SH model)
I think they are pretty good, especially the ball-bearing ones. They have more size options. I think the turbo we are running is one of the best for this power level, we are making a lot of power with little boost.
Yes oem + sleeper
Not as necessary in a left hand drive car. Right hand drive cars have the steering column brake servo and clutch master cylinder close to the turbo so a rotated set up is a better option for room.
Probably true.
That s30 in the background 😊
Great video as always, what turbo produces more HP and better spooling?? pte stock location 58 mm or efr 7163 with SX-E style comressor housing ?
I think the PTE will make more peak power but a rotated mount 7163 will spool faster. It's a really good turbo for a Subaru. We are building a car now with just that combo.
Hey Mike, big fan! How does the responsiveness/transient response of this setup compare to the Borg Warner EFR 7163 with the Full Race twin scroll header from your older vid? Do think the tech has evolved to where the twin scroll isn't that beneficial?
I'm running a similar stock location setup to this, but I'm looking for more response.
The BW will be better of course but I think this will make more peak power. We will be testing soon, standby.
The video turned out really good! What turbo model? Keep up this incredible work!❤
shop.precisionturbo.net/gen2-58mm-subaru-bolt-on-turbocharger
Thanks guys!!! Make a video of the car with this turbine in action! ❤
if you go to my daughters instagram kurisuta.k I think she might have some.
Rotated ftw 🙌🏼 more power at top less restriction 😘
In our opinion not for 520 whp and below. More than that yes of course.
rotated is easier to work on, less cluttered, better looking, etc. etc. etc. if you’re gonna build the car, go all out.
Trouble is most people don't do them right and will have trouble once they do a track day. For under 520 whp this is the way to go.
This guy is a genius
Yeah, that's Turbo Jesus, right there....
Depends on how much power you're trying to make.
FP zero will do 700whp stock location, but Its next to impossible to have the turbo inlet pipe under anything other than an ams manifold, a lot of people end up running screens. Rotated has better turbo options, its a crap ton easier to work on the engine in the long run, and you don't have to crush down the inlet under a manifold restricting flow. So yes you can make power with the stock locations, its just a shit ton easier long term to do with a rotated setup.
Like we said if you want to make well over 500 whp then rotated is the way to go.
Idea for future video rear/remote mount turbo setups
They don't work as well, we wont use them unless its unusual circumstances. They are laggy, turbos need heat and expansion.
Good night. Thanks for your content. Can you provide a link for this stock turbo in your presentation. I’m planning to upgrade from my stock turbo.
shop.precisionturbo.net/gen2-58mm-subaru-bolt-on-turbocharger
Thanks man.
Will u do an episode on water methanol injection...pros n cons?!
I should
yall should test the bcp x500r. i hear they make 600 whp on dynojet stock location stock inlet size.
Other people we race with that have say they make good power but are laggy. The dyno charts they have show that they are a little more laggy. My opinion it would be hard for your average driver to feel that amount of lag.
Id love to hear what you think of an fp red turbo same hp rating of about 500 without rotation
Its pretty good but I feel less turbine side flow
Yep this video earned my sub I'm gonna keep you guys in my mind i wanna buy another ef civic sedan or a Honda fit and do some fun stuff me and a buddy both had ef sedans and put k series mirrors outta tsx's in them it was the most fun id ever had my buddy eventually turbo'd his will mine got killed by a dui driver parked in front of my house he was a off duty cop doing 70 plus mph in a small neighborhood it shot my little civic 3 houses down in someone's front yard it was the saddest day of my life 😢 ive yet to buy another one it's hard to find a good example of a old ef mine was a 90 and my buddies turbo k20 one is a 89 it makes 420 whp i love going Coyote hunting with him and pissing off all the mustang fan boys
Thank you, which model turbo is it? I was thinking of the rotated setup however this seems like an ideal solution.
www.precisionturbo.net/turbochargers/factory-upgrade/details/Factory-Upgrade-Turbocharger---Subaru-WRX--STi--Forester/547 this is the 55mm inducer which is probably the one for 2 liters
shop.precisionturbo.net/gen2-58mm-subaru-bolt-on-turbocharger
This is the 58mm inducer version we tested that we would use on 2.5 liters.
DUDE THE GUY THAT INSTALLED THE PART IS SO FINE 😍😍😍
You guys should do PODCASTS
On my ej22t 93 tleg there is no room for a bigger stock location turbo. The vf40 I have stuffed in there barely fits.
Love love love this! This is the info we need. I'm curious tho....how much peak boost ? Was it on gas or e85? And 2.5?
Yes it was an EJ257 peak boost was 25 psi tapering to 18 psi. Not that much. On E85. If you want to read more about this car, check out motoiq.com/category/projects/subaru/sti-gen-2/
@@motoiq I appreciate the reply and all of the work you share. I considered the precision drop in but went with a 3076 externally gated stock location. I was 450 whp on a dynocom with a similar boost and it sounds like that precision would have been the better choice for the street. It's not bad, just not as smooth as I had hoped.
What AR exhaust housing do you have?
@@motoiq I'm pretty sure I'm on a.83 and it's spooling around 3800-4000.
An 83 is a good match for a street car. You might want to try one of the newer G series turbos, those rip with faster spool. The 3076 is sort of a slow spooling turbo, a G series in a rotated mount will be super awesome!
Why is dudes voice so soothing tho?
i always figures rotating was more about a front mount placement than anything
Great video! For 400hp in the crank you recommend the same?
400 crank HP you can have a stock bottom end with proper tuning. This is crank not wheel hp. wheel hp is about 20% lower.
smiley Mike for the win !
Geat video mr motoiq
I’m actually curious what you think of bnr super cars stock mounted turbo. I have their 18g and it seems to be alright for a daily. Just curious your thoughts
Never tried it.
