Turbo Blueprint

Alright guys I'm trying to scratch the surface and trying to get my turbo blueprint started so I can have an idea of how much to save. This spring I will be swapping an h23a vtec into my 4th gen lude and going for either an m2b4 or m2t4 transmission with a new clutch. After I get this setup put in my lude I will attempt to boost it stock at a low psi until I can save enough for a full rebuild. Right now this is all of the stuff on my list. I do have a couple questions and I appreciate any help!

-H23a Vtec with an auto to manuel tensioner swap
-M2B4 or M2T4 LSD transmission w/ a new clutch

-T3/T4 Turbo (a couple questions regarding sizing and brands)
-All necessary piping, intercooler, and downpipe (brand undecided)
-External 38mm wastegate (brand undecided)
-Blow off valve (hks ssqv or sqv)
-Log manifold (unless I find a better mani at a good price)
-Gauges: Boost, and oil pressure (questions, also thinking of going prosport)
-Skunk2 intake manifold bored with a 68mm throttle body
-NGK spark plugs and wires
-Walbro 255lph, 880cc injectors (questions)
-Chipped and tuned on a p28 (looking for somewhere between 250-300 whp)

My questions are:
What trim and a/r should the t3/t4 have? Also what brands are best?
What gauges would it be good to have besides oil pressure and boost?
Are 880cc injectors too much for this setup?
Whats the most whp I could get out of this setup?

Every day I'm gaining knowledge and researching like crazy! I still know I've got a long ways to go I'm just checking if I have the right idea by doing this blueprint. If you guys notice anything missing or see that I got something wrong PLEASE correct me! Thanks a lot guys!

Re: Turbo Blueprint

I think that the 880cc injectors are going to be to big. Boosting it on 10:1 comp is going to be dangerous unless you get a super amazing tune. And there really isn't a way for us to tell you how much WHP based off of this list. Your going to get this responce soon so ill just post it for you. Start here ===> So, you wanna go turbo, huh?

Re: Turbo Blueprint

You can never go to big on injectors lol that's what the tunes for

Also look for a t3 turbo an 60.a/r should do the trick ...

Boost/oil are your main gauges to have

Fuel an air is personal prefrens

Re: Turbo Blueprint

treadstone h22 turbo kit(i dont suggest u buy it yet until i get mine installed so i can tell u how it is).. came with precission turbo, all the pipes, etc.
-hks bov (240)
-bosch 550 cc injectors-230
-competition clutch stage 4-390
-aem a/f ratio gauge, autometer boost and oil pressure gauge <350
-gauge pod 40
-aem map senseor 150
-aem boost controllor 150
-aem meth kit:350

all these prices are canadian so if anything it should be cheaper for u u lucky bastard :).

Re: Turbo Blueprint

Thanks for the input guys!...So 880cc injectors can be ran with my setup? Also anyone recommend any specific types of wastegates, intercoolers with piping, and manifolds?

Re: Turbo Blueprint

880s are good for your goal.

Recommend tail - wastegate 38mm
Basic log mani would be ideal
I also was looking into the obx mani a while back,
Prelude eBay intercooler with 2.5 piping is also ideal

The people I know who have a polluter build usually swap in a stock engine or get a hookup.

Re: Turbo Blueprint

Turbo is a long process. The setup you want will be adequate at 7-10psi. Nick will agree, if you are gong to use any engine, rebuild a f22 for 15-20psi. The 880 injectors will give enough fuel up to 15, but going 1000cc is key. You'd have more space for intercoolers, lines, and choice of manifolds. You need to decide where you want the wastegate and BOV, although nick might advise against one (he knows turbos) and the tune. If you make this your progress thread, you will have our full support!

Btw turbochargers from turbodiesel trucks give great off the line power, and cheap (truck forums sell their stock units cheap) Garret (duramax diesels) or Holset (Cummings diesel). Powerstroke diesels, no idea. Rebuild it if the unit looks abused, and voilą new turbo! The hardest parts are figuring the remap, the air/fuel ratio and the temps. Anyone can slap a turbo together. It's the discipline to get it right that's hard.

So I could run 1000cc injectors with setup without causing harm? I plan to run between 5-8 psi max on this stock setup...until I save enough for a full rebuild!

Re: Turbo Blueprint

Well that's the point most turbo people will tell you: get the good stuff first, and cheaply so you don't have to buy crap twice. 1000cc injectors with a manual fuel pressure regulator is better than a lean condition with 880cc. Yes the tune is involved, but you're gonna get the boost itch. You gonna try 12psi, then 14psi, then you're gonna want more... So assemble a middlepack kit, in case you want some 350+ hp car... The cost is about the same. And keep reading that turbo thread!

i would look up kaizenspeed.com there really big with h series motors and have a very nice new tensioner design that does not fail!!! how do i know i have one i also bought a balance shaft elimination kit for125$ well worth it also increased my oil pressure which means vtec hits harder because alot more flow is making it into the head

Re: Turbo Blueprint

going to need atleast a 3 bar map sensor too i was going to go with a s300 but decided against it because i got a great deal on an aem standalone it has so many tuning capabilites my buddy has a all stock motor one peice charg piping custom made custom made intake manifold with all emission egr etc deleted 440cc green top injectors custom ramhorn manifold guy made 464 whp on stock internals just because the standalone allowed him to adjust the fuel rate and boost equally allowing more power the standalone also in a way tricked the map sensor into allowing more boost he tested this for over a year giving a little more boost at a time he intentionally with this setup tryed to blow up the motor just to see what it could really handle he made 500whp at the end with 28psi of boost that finally blew the motor but just the ringlands i have proof of all this even dyno charts if interested i would buy the standalone first!!

Re: Turbo Blueprint

and aced preludse to answer your question about how the people in cali pass the smog test is not fun most of them either own two of the same car one stock one not and risk the insurance fraud 2nd they have stock motors they swap in once a year to get reinsured thats what my bro does in cali he put pins on his car so the whole front end is removable for swapping the motors in really fast
