Every time a video drops from you, I wonder why this channel does not have more subscribers. This dude be dropping gems on a weekly basis. Thanks Billy.
500whp is my goal as well - Haltech Elite w/ E-content sensor, AUS1000 (newer, improved ones), dual intake, Z1 intercoolers, JWT HD clutch… under $5k. Working bugs out now before going to tune. Also worth noting that Haltech tech support is AMAZING! …for those leery on DIY standalone work. Just take your time, learn and plan… and follow your plan.
That's awesome! Going to be a really fun setup with stock turbos. I've heard how great their customer support is, fortunately I don't think I've ever needed to use them for anything.
@@Billy_Built I worked through my wiring plan beforehand, then after install, dude remoted-in and completely set up the whole map (multiple tabs for different purposes) and set me up for fuel self-tuning. In a way, I almost wish I wasn’t able to cruise around - I’d have more incentive to finish ironing everything out. I did disable it a few days ago to force me to work on it, lol.
@@Billy_Built I’m aware. I meant in the same fashion as this video though. Just a breakdown parts/prices with maybe two of your favorite ways now that you’re done with the build. If one of the two ways is a single turbo setup..that would be awesome
1990 N/A owner here, the standard side feed injectors are a major weakness on these cars. The 1st generation of these cars especially suffers from them. Headache after headache of misfires lol. Do yourself a favor and switch to top feed injection. Like Billy said, they are more efficient, better spray patterns, and cheaper in the long run than buying Nismo injectors, dealing with garbage failing ebay injectors, ect. Also, please don't buy injectors or spark plugs from ebay. I have had some bad experiences on my friends cars, and my own when it comes to defectiveness.
Trying to reignite the flame with my 91 TT and fix the damn fuel pressure issue that’s robbed me of months of fun driving 😔 Have made almost this exact list in my shopping cart many times, have all the major upgrades minus turbos and only chipped, just need this fuel problem fixed so I stop hating this car lmao Great channel I wanna say I’ve seen your build in the FB group if I’m not mistaken
hey Billy, Jett here I am having my 1991 tt at Z1 the week of August 5th...right now I have 110k on stock engine and turbos...having the Haltech PP installed and tuned. If my turbos are still great we may stop there but...if we go with their 525+ turbos should I go ahead and have them do the AMS manifolds? They won't do downpipes but I already ordered a set of 3" AMS to install afterward...I currently have a full Borla exhaust from the downpipes back. They are recommending the Nismo 740cc injectors either way and a full flow oil cooler if we upgrade turbos. I plan on doing as many track days and HPDE events as possible...we typically run a 20 minute session which means running hard for 15 minutes...so max power is not the goal but steady consistent power is. I figure high 300's hp maybe 400 torque at say 15 pounds of boost on stockers, 500 each with 525+ kit at the wheels. Thoughts?
If you're going to change the turbos out, you might as well upgrade the Turbo manifolds. It's one of those things you might as well do while you're in there. Z1 should definitely be able to take care of you if you express to them what your plans are with the car.
Bellmouths have been made previously by a different company and performed very well. I would imagine these would too. The other option in that range would be the specialtyZ downpipes.
my thoughts on this is, the best exhaust for a turbocharged engine is no exhaust at all. Being we need to have an exhaust the the next best exhaust is as large as possible at the turbo outlet, bellmouth is as big as the turbo outlet, split pulse has a small opening behind the turbine wheel and when the wastegate is closed all exhaust gas is going through that small opening the higher the boost and larger the turbo the wastegate is staying closed for longer making the restriction worse.
I have been looking to switch my setup to e85. But as America is more eyed to electric hybrid and eventually all electric by 2027-30. I wonder how long e85 will be around. Manufactures combined only offer 4 vehicles that run e85 in 2024’s lineup. I understand live in the now and enjoy what we can use today. But the next 5 yrs will be very interesting for us enthusiasts. Thanks for the Z content. A haltech is on my wish list either way.
There will always be the next alternative. All depends on where you live. E85 is pretty abundant where I'm at. If They ever stop selling E85, which I don't know why they would because it is way better for the environment. I'll probably switch to water meth injection, or some other fuel.
I don't completely agree with you, the NISTUNE is actually pretty good and much cheaper than a stand alone. I have killed of 3 sets of side feeds (subaru sti 550cc) so thats true but it was my fault. When I bought a brand new harness and made my own grounding kit... that problem went away. If you have a tt right off the bat then yes that fuel pump is fine, if you're like me then a walbro 450 wild be a great place to start. I could be wrong but i don't think the secondary MAF is needed either...if sticking with the owm modded computer.
Side note: I've owned a mk4 supra since 2017 and I've learned that 500whp is also a very good "Sweet spot" for reliability. Everyone says "duuuude it made 750whp on e85! why'd you turn it down??" and the answers are the same. Just because 700hp is very doable on E85 with an unopened bottom and a built head does NOT mean it definitely should be done. It is a very "annoying" version of 700hp. Getting roasted by sub 500whp cars left and right in the real world because I only make that power after 6000rpm and have to shift immediately vs downsizing the turbine and making 500whp where it punches to it in less than 4500rpm and I can stay in it way longer at that level. The 700+ setup is probably miandering around the mid 3s or less until at least 5000rpm. This concept is lost on everyone except those who deal with it.
Oh ya, forgot.. my point also being that you ride a thin line in the 700s on stock bottom end. You constantly run the risk of spinning bearings from how quickly your oil becomes diluted with ethanol all the time and pushing that much more pressure and heat. Ethanol is no miracle drug (though close). But having to change oil every 1500 miles and sooner is a drag as well. Rods are under a lot of stress post 600 ft lbs. (which at 750whp, they are). If you just run 500, you can enjoy it on pump gas and dial that in perfectly. Then enjoy slightly more sane oil change intervals and have all that extra headroom of almost 300ft lbs less torque being experienced - however brief - while making more of what you do make more often.
thats AMS in canada that copied everything from other vendors that put in all the R&D on the parts. Most of thier stuff doesn't fit well at all anyway. Just wanted to clarify that he is not talking about the AMS in chicago! They are badass! lol!

Not an insanely popular model so being model specific limits audience.
this channel is such a gem. Keep up the good work man.

i love all of your videos on the 300zx man, great job on all of them!
Just got my very own Z32 2+0 last week, loving that oem+ look your car has billy
Enjoy it!
I make 500whp on E85 on stock turbos !! I love my Z
What mods are you running? Ive been looking into doing the breather mods (2.5" intake piping and 3" exhaust)
We need to get this guy a sponsor ASAP!!
I support this😎
I have an idea for a new video. Similar to this one, but 1,000hp instead (single/twin turbo). Would you please do that?
That's basically my current build. but I could do something like that.
@@Billy_Built I’m aware. I meant in the same fashion as this video though. Just a breakdown parts/prices with maybe two of your favorite ways now that you’re done with the build. If one of the two ways is a single turbo setup..that would be awesome
@@shawnalbarghouthi4113 gotcha, yeah I could do something like that!
We need a parts list and maby links in the description. I'm missing a lot of these parts in my build right now and having a hard time finding parts
Thoughts on Nismo 740CC injectors?
Good for a side feed injector and 500hp.

You can build my TT 92 at anytime Billy. I’d help and pay you for it, and I can designate $15k for parts
Me too I'd do the same but I'm in Canada Vancouver
I want one of those intake manifolds sooooo bad!!!!!!
With a standalone ecu, when using map sensor do you still need the IACV and the other sensor behind the plenum? Thanks.
Thanks man this all helps a lot
Hey can you send a link to that sz 6.5qt oil pan? Thanks!
I would love for you to build my 300zx . I have a 1995 twin turbo with a blown up motor 😮
Trying to reignite the flame with my 91 TT and fix the damn fuel pressure issue that’s robbed me of months of fun driving 😔

@@darianmunoz9790 I've been around their for years 👀 lol
X2 turbos upgrade, intake , exhaust, fuel pump , intercooler 3000 tops
Well Spent, Billy!
Dan the man👍
i want a build like yours
great advice man!
Glad you enjoyed it!
I know I've asked this a few times but how fast could twin g25 550 on your set up in terms of rpm or overall
@@benjaminphantomhive I would guess a couple hundred RPM sooner on an identical setup.
What is the injector setting for Nismo 740cc on haltech platinum pro
That is a question for the tuner.
Great video. What boost would you anticipate you'd need with the mods you've mentioned to hit the 500?
Great question actually. I would expect anywhere between 15-20psi with E85 and stock TT compression.

What about an upgrade water cooler?
you mean like a radiator?
nice! what your setup wheels? thanks
It's in the description
What would your labor charge (fees) be🏁💰
I only take blank checks 😎
@@Billy_Built 🏁🏁🏁🤣👍
Have we seen any chart or proof for the bellmouth downpipes being worth the extra money?
Bellmouths have been made previously by a different company and performed very well. I would imagine these would too. The other option in that range would be the specialtyZ downpipes.
@@Billy_Built seen em on other platforms, it makes sense I'm just hesitant to drop 2x the money but every bit counts
my thoughts on this is, the best exhaust for a turbocharged engine is no exhaust at all.

2:16 build mine 😭 nah i need to upgrade everything hahah previous owners didn’t do maintenance 😔
I believe in you. 😎
Great video. Lmk if you want to sell your old platinum pro now that you’ve swapped to the elite.
Soon enough. Lol as of now, the funds are not there to replace the one I have. 😅
@@Billy_Built time for them to sponsor you.
@@Zi.Zenior anything is possible

major manufacturer defects in their latest release.

Nice job with the CZP sponsorship. :)
🤣🤣 I wish. 0 sponsorships here..
I refuse to call a tuning that requires me to take the engine out of the car as "easy" 😉
I shouldn't have never sold my 1990 300zx Twin Turbo (5-speed manual)🏁🏁🏁😁
Believe in yourself. (Get another) 🤣
@@Billy_Built I think I will eventually. I miss my Z🏁🏁🏁😁👍
Nice video. I just realized that somehow I wasn’t subscribed.
@@BlaineDownforit thank you🙏
How come no SpecialtyZ love? At least for the Down pipes that the other company copied.
I definitely recommended their oil pan.
600 hp for less than 10k will give v8s a run for there money on a budget lol
Me with my NA 😅
so since this video came before the engine rebuild one.. is it still the way to do it? or... lol
well yeah. they're totally irrelevant. my build is meant for well above 500hp..
🏁🏁🏁🎬👍
Nothing is easy with these cars super complicated to work on ....
Only if you're mechanically inept!
Didn’t make 500 lmao with 20k in it
The good news is that it’s wasn’t don’t on a good dyno
