Mike, I had a disco potato on my S13 in 2004. Bought it after reading about Dave Coleman's car in SCC magazine. This is making me want to build another S-chassis. So many memories.
Are you talking about the SCC S13 Silvia front with matte black rattle can finish? That was a huge inspiration to me. Instead of the Disco Potato I went with a Garrett GT25R small AR (sort of the precursor to the 2871). It was available from Phase2motortrend. My S13 is still a garage kept survivor car from those days!
@@vqdriver The one and only. I actually still have the magazine article cutout around here somewhere. My hatchback had the GT2871R then the GTX2867 which Garrett told me was the new version. Unfortunately never got it running right on that GTX. That was a me/funding problem, not a turbo problem.
Lovely video, Mike. Thanks for showing people the basics. A lot of people forget that a car doesnt need major upgrades in order to put a smile on your face and be reasonably quick. Past this point, you end up changing the characteristics of the car by needing to do drivetrain upgrades. Its kinda the point of no return and ruins the fun of an s-chassis. A lot of S-chassis' would still be on the road if people did not go past this point, and more importantly focused on traction and safety items like quality wheels/tires/brakes/suspension.
Touching on the ECU/controls upgrade would have been nice. Maybe in part 2? For example I assume you're going to a MAP system because of the atmospheric blow off valve setup you displayed. Will you guys be reprogramming the stock ECU or going to some sort of stand alone? Is reprogramming a stock ECU even possible with a MAP setup? Love the content. Keep it up!
Still have my 240 i bought in 03. Not in the best condition but i just cant let it go LoL. I went with the s15 t28 turbo, tomei manifold(which is cracked now) 550cc injectors, tomei poncams and a RS enthalpy tune. Car has been sitting for a number of years but i am in the process of getting back on the road. Miss driving it
woooo thank you keep us sr20det guys happy wiith vids like these .... weed love more in-depth sr videos ... hands on stuff bud ... swap stuff too ... im running a s14 zenki disco pat... in a datsun roadster ... and love this content
Also to note a bit of recognition to Enjuku for improving their ISR lineup. Those exhaust parts appear to be pretty nice, high quality SS construction. It looks like they have come a long way.
I’ve been watching ur videos and was hoping sr20det builds will come up and my prayers are answered. I’m going for reliability + power on a stock end sr20det i like this build but 2871r will suit me better. Many thanks 🙏
the small borg warner efr 6758 t25 can bokt up to the stock manifold just about did it for a bud a couple years ago on a stock red top with rotary 550cc injectors twin 044 fuel pumps run by a local $150 ecu made 375hp all day and is still running to this day just with a bigger intercooler and e85
Hi Mike, quite interesting! I have been into S Chassis for well, 20 years and grew up following your pioneering work and came to similar conclusions about 10 years ago when I built my SR20... although I would like to offer some alternatives (not criticizing your choices mind!) In my experience, the 2867 has it over the 2863. On E85 I made 324rwkw (430rwhw) @ 6500 with an S15 engine. Could argue the dyno etc but it blew the standard S15 box in the classic 3rd-4th pull so its up there. I had a 2863 but the 2867 just has that little bit more oomph though I ran the smaller 0.63 rear housings perhaps the 0.86 2863 is better but g25/g30 certainly seem to be the future though. The Standard s13 exhaust manifold with a minor port does have its benefits (cheap and reliable!!) and I did not feel was a restriction, although the s14/15 variants loose a bit on runner 4 from EGR crap. I have cracked innumerable stainless steel exhaust manifolds that look identical to the ISR one (ie with the reinforcing) Id suggest dont waste your time and stay with the stock one or go proper steampipe The standard s15 intake saved money although the injectors and fuel rail were a pain with a spacer plate etc. s13 packaging is better but is really limiting for some reason. A 1 piece front+ dump pipe seems to be better and cheaper at least with local experience. Otherwise I run poncams/springs and a haltech platinum plug in, CD009 via the mazworx bellhousing but using the serialnine shifter. works good.
I agree with you that the 2867 is gonna make more power but I am not after more power, the transmission can't take very much so why bother is my thinking, I will take the smaller compressor wheel with less slip losses and faster response. I guess you found that out too! The engine is much, much happier with the 86 housing from a tuning standpoint, much further away from detonation. Don't agree with the manifold, this manifold will spool around 500 rpm quicker and again give more tuning headspace, plus it won't crack ever with track use. There are a lot of crappy SR20 manifolds for sale and this isnt one of them. The JWT cams will eat ponecams for lunch. I will make equivalent power with faster response, less boost and less overall thermal stress on the engine. Will go to the CD009 once the std trans dies. At that point, I will probably go through the motor, run a G-Series turbo and make another 100 hp.
@@motoiq very intelligent and wise responses! Thanks man! I think my next move is g30 and a sixboost manifold so perhaps we would end up at a similar place..... If you were going VCT would you still suggest the JWT cams/springs? My brother ran BC cams/springs on a s15 engine....killed the vct in 2 trackdays...
Yes, they consistently produce more power and wider powerbands than any cams in the same duration category with less valve spring tension. G30 is a great choice.
@@motoiq should have said. I'm not sure I noticed any loss in response with the 2867 (gen 2) compared to the 2863 (gen 1) but perhaps it's cams and manifolds and rear housings that are preventing getting power earlier with the 2863.... Anyway appreciate the video and the time you took to reply!
Sounds like this car is built to the similar goals I want for my AE86 hatch that I'm trying to stuff my RX8 motor into, except I'm pretty sure there's no class racing that my car would be competitive in, especially N/A like I'm going for
Garret g25, intercooler, fuel pump and injectors. Cheap option is to get a hypergear turbo for half the price. All up it’s like 2500 and the turbo will support 700hp. Bought one to replace a factory op6 on a neo engine, spooling on idle. Same size as a t25. Shits on a 28… was $1250 au delivered.
I've got a nissan 200 sx 1996 with sr20ve, mega squirt 2 computer hitting 183 hp, Im new in the automotive world and want to get more power without adding turbo
Hello, loving the content on the sr20's. I was originally going with the GTX2863R with dual ball bearings, however i saw that the t28 S15 Garret turbo is cheaper. Enjuku says the t28 s15 turbo bolt on pattern fits an S13 sr20det. Would I be better off going with the t28 s15 turbo or GTX2863R because the t25 has dual ball bearings and the t28 does not. Great video thanks for helping me out!
Thanks for very informative videos presented in a humble and and thorough fashion. About this SR build, I have a question when it comes to cam gears. I'm assuming that this base engine was non-VCT to begin with. In such case it makes sense to put adjustable cam gears in together with the aftermarket cams. But what if the engine was a VCT SR20? Your goal here is "no so much about to end" and more about response and torque. If you had a VCT SR20 to begin with, would to have kept the VCT or sacrificed it in favor of adjustable cam gears? And, further, if you would have retained the OEM VCT, would you see any advantage in having an adjustable cam gear on the exhaust cam? Or wouldn't that make any sense unless there is an adjustable gear in the intake so both can be adjusted together?
I'd guesstimate the target airflow will be about 40lbs/min at 2.5 PR. At that point, comp efficiency of the 2863 is 65% vs. Only 60% for the 2860 G2. The 2863 has a good chunk better peak efficiency too which will improve the midrange.
May you inform me as to why this is a better turbo option. I was about to purchse a Garrett Gen2 2867R .86? As also looks to be direct bolt in. My goal is to be closer to 400whp on 93oct thanks!!
@motoiq Excellent video, thanks for the valuable information. Have you got any experience with modifying the roller rocker SR20DE engine for racing? Just wondering if you can comment on the durability of the OEM roller rocker with uprated valve springs and cam in a racing application? Thanks!
@@motoiqThanks for the help. I am building an S14 SR20 and converting to the roller rocker with the shorter valves. I've figured out a dual spring for it using the SRVE retainer and a custom spring seat. It will be around 80lbs on the seat and around 220lbs at 11mm open per spring. Still working on the cam profile. It will be a street engine. The roller rocker is fairly rare compared to the slipper pad, so information on the roller rocker durability is fairly rare too. Thanks again for the great videos!
Roller rockers require a difficult to engineer inverted flank profile which is the main reason why you cant stick a decent cam in them, it is defiantly not worth the effort and will make less power under the curve. JWT is the only company to offer anything. JWT C series cams will greatly outpower with better powerbands any roller profile.
The only off-the-shelf cam I can find for the RR engine is the JWT S3R which is a 262deg cam, slightly lazier than their slipper pad 260deg S3 cam. I'm already a bit too deep into this to back out haha so wish me luck! Thanks again for the great videos, keep up the fantastic work!
Don't try to designed your own cam, most aftermarket grinders cant even get the math right. You also need a Berco cam grinding machine with a small 4" or so wheel to grind this sort of profile. Most cam grinders use larger wheels for more speed and less problems with dimensions in production.
I purchased the ISR V3 SCH-10 manifold in reference to this video just received and realized in this video your are recommending the V2 which is of SUS 304. Now im wondering is this newere version better or worse have you seen it and would you recommend? Suprising there is next to no reviews of these online depite both versions being out for awhile. Thanks!
Interesting observation: Engine masters has basically demonstrated that a turbo engine has, basically, the same power curve that is intake manifold dependent.
@@motoiq sorry, but since i cant get in touch with Garrett honeywell. Which size of oil restrictor is recommended for this turbo on sr20det? 0.9mm or 1.1mm
Hi I have a Nissan B13 Sentra and I need help there's a GA16 inside with a manual gearbox but my problem is no current flow to the starter and fuel injectors, Please I don't know what to do.
This is great info as I find myself checking what I did so far in my SR20, and sometimes I feel like I need to backtrack as a result. Do you have an opinion on the Garrett G25-550 instead? I have a 3071r ready to go but I’m thinking it’ll be too laggy.
Would you recommend some adjustable cam gears on a De motor with some 260 drop in cams? Also on any tips on the intake manifold side on a B14/N15 low port, apparently its a hard thing to get gains out of
@@motoiq I've been told the low port flows well, I had a inlet and TB body sent away for port matching and the man who done it they are pretty good, just wondering if its worth the effort of fitting it, to pair up with throttle body on the car I'm useless when it comes to engine work, but I do know some very handy people with SR20 so I might have to invest in some cam gears! Pretty desperate for more power in the mid corner on track
@@motoiq kia ora bro, just wondering why do rocker stoppers damage engine, ? ive got a stock sr and have stoppers. So i just remove stoppers and we good ? thanks for the content bro. keep the sr content coming please. cheers brother
I'm kinda surprised that you guys would choose to run a BOV vent atmosphere. I'm curious if you think a recirculation setup would be more responsive. Also wondering how you feel about the high mount intercooler setup. I'm currently building an SR for my S chassis.
We are going to run speed density with a MAP and get rid of the MAF, then we can vent to atmosphere. If we were running the MAF then for sure recirculating is better. Front mounts work vastly better for charge cooling.
What route did you go with recirculating? Seems to be very little aftermarket support for intake piping with recirculating ports. Or even BOVs that easily allow recirculating
I'm still a bit curious as to how the .86AR turbine housing fares spool-wise. Didn't really think to imagine a large housing in the same sentence as fairly quick spool unless it's a twin-scroll like an OEM Evo turbo paired with its own manifold.
@@motoiqwhere do you find is the best place to source transmissions for the p10. I would like to at least get a p11 trans for that stronger 3rd gear, but they seem to be hard to find. The company JGY shows that they have them but reviews on their business practices are not great, and I am not sure they are still around.
@MotoIQ Hi. Im planning to go without kitten&straight exhaust my 1zz-fe Celica. Its 1.8L 4cyl 143bhp NA can you recommend exhaust pipe size after stock resonator for reliable performance and velocity? question1. is resonator still good after 23years or needs replacement question2. does having same size pipe all the way matter? and are there any benefits to go smaller than 2" size, because stock pipe is 1.811inch i believe.
you should do it from the header back, not just after the resonator. and no there isnt a benefit to going under 2", but honestly you could just spend the money a 2zzge swap instead
@@arcanevoid9199 sadly we dont have any 2zz engines in my country cuz here everyone has diesel cars and i guess it would be cheaper to buy 2zz from toyota spending 8k
@@motoiq I’ll look into that as well, right now it’s just a stock det with a 3” vrs downpipe… I’m assuming the disco will swap in with my current downpipe and manifold… not looking to be the fastest just have fun with an se-r I’ve had since 1999…. I’ve had the car since the se-r mailing list days.

I planning to change my set up with "79E" rods because are lighter. At time my engine makes 380hp. Which is your opinion for "79e" rod finally? Is something same or not?
Well......this is the video that might have changed my mind. I have a '77 Datsun 620 and I was going to run a KA24DE(T) but now? Jeeze..... SR20?! Regardless, I'll be giving you fellows a call to have it done right! EDIT - If possible, I'd love to hear your thoughts on air-to-water intercoolers, equipped with mounted electric fans, for applications like mine where the owner doesn't want to cram an FMIC into a classic front end
It would be helpful to link to some of these items. It seems that searching for some of these isn't just straight forward. Other than that, Love the videos tho.
Snowball of a choice. And like twice the cost of the gtx2863. Great turbo but then you go vband and ewg which are pricey for this 'budget' build. They do have the t25 iwg housing, but that turbo also wants to be at like 400hp+ which you probably want to do bottom end stuff too. I've been flopping around a decision for my SR and the 2863 is really hard to beat all things considered.
@@zacharykarr not all G25 turbos are EWG. They have a few IWG choices. They are the smaller A/R housings as well so better response with less maximum boost. But like you said they flow more air and they are physically larger than the gtx2863 turbo.
Thanks for your reply, I have an s14 sr in storage waiting for a 2024-2027 s-chassis. Artec vband bottom mount and g25 were on my wishlist. Will reconsider the gen2 @@zacharykarr

Their search function is your friend.
I purchased the ISR V3 SCH-10 manifold in reference to this video just received and realized in this video your are recommending the V2 which is of SUS 304. Now im wondering is this newere version better or worse have you seen it and would you recommend? Suprising there is next to no reviews of these online depite both versions being out for awhile. Thanks!
Main difference is thicker schedule 10 weld-el tubing,
im assuming this is for an s13 Sr20. Is it true cams in the s14 Sr20 is not a good idea because of possible issues relating to the VTC gear?
No
Interesting observation: Engine masters has basically demonstrated that a turbo engine has, basically, the same power curve that is intake manifold dependent.
Can you recommend a turbo for a target 400 whp build that can make that power while fitted with a 33mm restricter for rally rules?
Something like a G25-660
@@motoiq Thanks again, man. Wish I could turn wrenches with yall and learn some stuff
0.86 Housing is the way to go then? I just got minne GTX! I did order .64 but got .86. Maybe thats good, the sr is pretty heavy built
86 is way better for the SR
@@motoiq thank you! I value your support
@@motoiq sorry, but since i cant get in touch with Garrett honeywell. Which size of oil restrictor is recommended for this turbo on sr20det? 0.9mm or 1.1mm
1mm or so
Hi I have a Nissan B13 Sentra and I need help there's a GA16 inside with a manual gearbox but my problem is no current flow to the starter and fuel injectors, Please I don't know what to do.
Maybe a burned main fuseable link. The other possibility is the clutch interrupter switch or relay.
@@motoiq okay I'll see with these hits today thanks 🙏🏾
This is great info as I find myself checking what I did so far in my SR20, and sometimes I feel like I need to backtrack as a result. Do you have an opinion on the Garrett G25-550 instead? I have a 3071r ready to go but I’m thinking it’ll be too laggy.
The G25-550 is an awesome turbo.
Hi Mike.
Thanks for the video! Would you encounter potential boost creep with the internal wastegate at this power level?
No
Thanks for replying. So no real need to port the wastegate pre dyno- if running the bigger 0.86 A/R with this turbo?@@motoiq
you might need to adjust the cracking pressure out of the box
Would you recommend some adjustable cam gears on a De motor with some 260 drop in cams?
Also on any tips on the intake manifold side on a B14/N15 low port, apparently its a hard thing to get gains out of
The low port actually flows well. Adjustable timing gears are good if you know what you are doing.
@@motoiq I've been told the low port flows well, I had a inlet and TB body sent away for port matching and the man who done it they are pretty good, just wondering if its worth the effort of fitting it, to pair up with throttle body on the car
I'm useless when it comes to engine work, but I do know some very handy people with SR20 so I might have to invest in some cam gears! Pretty desperate for more power in the mid corner on track
Extrude hone the low port intake manifold, it is pretty hard to improve upon
Mike, lets talk about the VE, VET.
Its coming eventually
Great content. Whats your opinion on rocker arm stoppers? And can i run tomei 256 poncams with a differnt brand of springs?
Rocker stoppers are crap and will damage the engine, I think pone cams are designed to run stock springs. JWT cams are cheaper and make more power
@@motoiq kia ora bro, just wondering why do rocker stoppers damage engine, ? ive got a stock sr and have stoppers. So i just remove stoppers and we good ? thanks for the content bro. keep the sr content coming please. cheers brother
I'm kinda surprised that you guys would choose to run a BOV vent atmosphere. I'm curious if you think a recirculation setup would be more responsive. Also wondering how you feel about the high mount intercooler setup. I'm currently building an SR for my S chassis.
We are going to run speed density with a MAP and get rid of the MAF, then we can vent to atmosphere. If we were running the MAF then for sure recirculating is better. Front mounts work vastly better for charge cooling.
What route did you go with recirculating? Seems to be very little aftermarket support for intake piping with recirculating ports. Or even BOVs that easily allow recirculating
GFB makes great recirculation valves for many nissan engines SR20 included
I'm still a bit curious as to how the .86AR turbine housing fares spool-wise. Didn't really think to imagine a large housing in the same sentence as fairly quick spool unless it's a twin-scroll like an OEM Evo turbo paired with its own manifold.
A .86 isnt a large housing for a 2 liter.
Can you do some videos on a FWD SR20 in a G20 or just some G20 videos in general?
It's all the same.
@@motoiqwhere do you find is the best place to source transmissions for the p10. I would like to at least get a p11 trans for that stronger 3rd gear, but they seem to be hard to find. The company JGY shows that they have them but reviews on their business practices are not great, and I am not sure they are still around.
@MotoIQ Hi. Im planning to go without kitten&straight exhaust my 1zz-fe Celica. Its 1.8L 4cyl 143bhp NA can you recommend exhaust pipe size after stock resonator for reliable performance and velocity?
question1. is resonator still good after 23years or needs replacement
question2. does having same size pipe all the way matter? and are there any benefits to go smaller than 2" size, because stock pipe is 1.811inch i believe.
Probably something like 2- 2.25" if the engine is stock other than that.
you should do it from the header back, not just after the resonator. and no there isnt a benefit to going under 2", but honestly you could just spend the money a 2zzge swap instead
@@arcanevoid9199 sadly we dont have any 2zz engines in my country cuz here everyone has diesel cars and i guess it would be cheaper to buy 2zz from toyota spending 8k
Any recommendation for a fun street turbo for a B13 SE-R? I have a 92 SE-R with an Avenir DET w/ JWT ECU & Yellow STI injectors ( I think 500cc).
Disco potato
@@motoiqThanks!!! didnt know if that was till the Goto!
For lower power, its great for the money. A G25-550 is even better if you are willing to convert to v-band flanges
@@motoiq I’ll look into that as well, right now it’s just a stock det with a 3” vrs downpipe… I’m assuming the disco will swap in with my current downpipe and manifold… not looking to be the fastest just have fun with an se-r I’ve had since 1999…. I’ve had the car since the se-r mailing list days.
I know on a bluebird it wont, the compressor will hit the block and you got to switch to a GTI-R manifold, never tried on an Avenir.
we need an sr20ve build
Hello and greetings from Greece 🙂
Stock bottom end, with "79E" or "54C" rods? Which are the difference between those rods for power handle?
54C have bigger bolts and are stronger
@@motoiq hello good people, i need to know how much horsepower can handle a "79E" rod. I have nitrous set up with stock pistons (54C) and stock rods (54C). I planning to change my set up with "79E" rods because are lighter. At time my engine makes 380hp. Which is your opinion for "79e" rod finally? Is something same or not?
You are about there.
So, in the video we watched, you mentioned a stock bottom end that can handle up to 400hp. Were you talking about "79E" or "54C" rods?
Any of those as long as you don't detonate them.
Still using the Disco potato on my B13 SE-R 😁
Need a video like this for sr20 de
Building the SR20DE is exactly the same as this video. Just switch the turbo for a header.
@motoiq I want to add a supercharger, do u recommend? And what brand, m45?
@motoiq i have a b13 with a sr manual
Do not recommend that
@motoiq recommended upgrades, just keep it stock?
Nice!
Please share with us your tuning skill on a Toyota 3S-GTE 😁😁
It's coming eventually.
I’ll tell the best Bolt on for your car, two words: k series 😊
KA
@@KARRwrong K motor
Well......this is the video that might have changed my mind. I have a '77 Datsun 620 and I was going to run a KA24DE(T) but now? Jeeze..... SR20?! Regardless, I'll be giving you fellows a call to have it done right! EDIT - If possible, I'd love to hear your thoughts on air-to-water intercoolers, equipped with mounted electric fans, for applications like mine where the owner doesn't want to cram an FMIC into a classic front end
Turbo KA24 isnt too bad either.
It would be helpful to link to some of these items. It seems that searching for some of these isn't just straight forward. Other than that, Love the videos tho.
Here you go! motoiq.com/the-full-bolt-on-sr20-engine-part-one-the-basics/
1200cc injectors for 330hp?
For more power later and ethanol.
Do you guys still WPC your engine?
If the customer will pay for it we recommend it
Can you guys build my 180sx 400hp?
Easy
@@motoiq how much it’s going to cost?
8-10k
@@motoiq can you send me the name of all the parts in that video please 🙏
Google is your friend
Why not a Garet g25-550?
Snowball of a choice. And like twice the cost of the gtx2863. Great turbo but then you go vband and ewg which are pricey for this 'budget' build. They do have the t25 iwg housing, but that turbo also wants to be at like 400hp+ which you probably want to do bottom end stuff too. I've been flopping around a decision for my SR and the 2863 is really hard to beat all things considered.
@@zacharykarr not all G25 turbos are EWG. They have a few IWG choices. They are the smaller A/R housings as well so better response with less maximum boost. But like you said they flow more air and they are physically larger than the gtx2863 turbo.
We talked about why in the video.
Thanks for your reply, I have an s14 sr in storage waiting for a 2024-2027 s-chassis. Artec vband bottom mount and g25 were on my wishlist. Will reconsider the gen2 @@zacharykarr
If you have a v-band manifold, the G series turbo is really good!
330 hp crank or wheel?
Wheel
@@motoiq thanks 👍
Good torque on an sr hello new box and isr eBay manifold I’m out
Well I think it's time for some vg33 info lol
Can you eventually do a vq35de build pleasereeeeee 💯🙏🙏🙏🙏
We did a 37 video
Potato Code Noted.

Not convincing me about that terrible exhaust manifold but guess it's a case of you get what you pay for
Objectively it is one of the best stock position manifolds on the market. We have run one on a drift car for years no problem.
That’s the colloquially known “Disco Potato” turbo.
That was the gen 1 gt2860rs.
This is the evolution of the disco potato that Mike himself was a part of creating/popularizing
