Ok I want to turbo my NA so I can actually beat people on the road now. There's a lot of different paths I can take, but I need help deciding on the right one. I have a NA automatic tranny, and i really don't want to sped the $$$ of upgrading the tranny, so i want to piece together something that i can run on my stock tranny without blowing it. If you could give me some suggestions they would appreciated. My goal is in the 300-400hp range. Please tell me the EXACT parts I would need, as I plan on piecing everything together and taking it all to Bruce Nomura. Thanks in advance.

Damn Dave you car is sweet!

Ok, I would stay around 300hp to make sure you don't hurt the tranny:
1) fuel pump-either a TT pump or a Walbro
2) manifold-probably a Fmax to save coin
3) CT26 turbo-the stock turbo from a MKIII supra
4) stock TT intercooler
5) blow-off valve of your choice
6) VPC for mkiii supra-with 550 chip
7) AFC
8) 550 injectors-high imp
9) gauges-boost and EGT
10) you'll have to get intercooler piping and a downpipe custom made. Also oil and water plumbing to/from the turbo will need to be made.

hey Dave H will that be 300 at the wheels

keep us posted of your progress....Dave U..

urmild your car used to be white.......right????
who did your paint job and for how much......

 

[uplusd]

me and my teacher painted it, came out pretty clean i guess... thanks for the help daveh, didnt you say something about trimming the compresser wheel on the turbo, and "clipping the exhaust" whatever that means..

much would this setup cost?

 

[uplusd]

I just talked to Bruce Nomura on the phone. I told him about converting my NA to the CT26.. Basically he told me he wouldn't really recommend it since the CT26 is outdated. Also having to rebuild/upgrade the CT26 would cost a lot of money which would equal the same as buying an aftermarket kit like the PHR non-turbo kit. He also said labor would be anywhere from $2,000 to $5,000 on a job like this. DaveH, your response would be appreciated.

 

[DaveH]

Sure the CT26 is a old design, but it is a good, tough turbo that works well with the supra engine, will make 300hp as you wanted, is inexpensive, and has a built-in wastegate so you don't need to spend the $$ on a wastegate. You can get it rebuilt/upgraded for around $450, or just run it as-is... since stock it will make the hp you want. It will be much cheaper than a Powerhouse kit, or any other kit for that matter. Will it be as veratile? no.... and it wont be easily upgradable past 400rwhp either. It will just be a inexpensive way to get 300hp.

 

[uplusd]

are you sure about this? lots of people told me that that turbo will not make that power... sorry to be annoying, i just need to know 100% about this before i decide to go with it.


oh and you said it will make 300hp, is that at the crank or wheels. with this much power what will i be able to smoke on the street?

 

[DaveH]

The most I've seen out of a stock CT26 was 354rwhp... but that is really pushing the shit out of it (probably overspinning it). It will make 300rwhp stock, at around 14psi. You can upgrade it (I have a 60-trim/clipped turbine) CT26 on my mkiii, and it will max out around 375rwhp, maybe 400rwhp if you really push it. I haven't dyno'd my mkiii yet, but at 17psi it ran 107mph traps in the 1/4 mile, which shows around 345rwhp.

With the stock turbo, my mkiii was competitive with any mildly modified mustang, camaro, ect.

 

[DaveH]

I just found a dyno sheet of a upgraded CT26 (60-trim) running 18psi. This is on a mkiii.

me and my teacher painted it

your teacher helped you out with the paint?, what class you taking? Autobody?

 

[uplusd]

your teacher helped you out with the paint?, what class you taking? Autobody?

i dont take it, my friend does, so i prepped it with him and then the teacher there painted it

 

[sdadlani]

cool, just wondering, i was thinking of taking autobody when im a junior

 

[Guest]

387hp and 400tq?? Wow you'll really get that much!? or is that at the crank and not the wheels?!

Rob~

 

[DaveH]

Thats at the wheels. The CT is a very good turbo (for a pea shooter)... heh heh My mkiii feels very strong with the 60-trim.

 

[uplusd]

ok im just about ready to buy the parts... what about electronics, what electronics should i get? i want everything that will make me good to go. turbo timer, boost controller/gauge, etc....

 

[DaveH]

Besides the VPC I would get a AFC, a boost gauge, and a EGT gauge. Turbo timers are handy but not absolutely necessary. The boost controller is personal preference, I've used a couple different EBC's, bit now I just used a MBC.

 

[mkivsoopra]

Dave, would this setup be running on stock compression?

 

[DaveH]

You may be able to get away without the gasket, but I wouldn't recommend doing it that way. Get a bad tank of gas and you could detonate and damage something. The headgasket is good insurance imo.

URMILD. . .love the paint job. What color mix did you use?
