You should be able to pass if it's tuned properly. The HKS kit will allow you to keep your air pump. It's an FC, right? What do you plan on doing for fuel?

10th Ann FC...
Any help in this matter would be appreciated but,
as far as fuel goes:
1. New pump
2. Adjustable Regulator
3. Modified Secondary Rail
4. 1200 Secondaries

Any preferance on any of these parts?

I also know that I need several electronics for this setup , but I am not sure on which ones...

That sounds like enough fuel for a TO4E. What ECU are you going to use?

Ya, I posted the dyno curve of this T78. Lousy low end power, only came in at high rpms. Had a giant cat to pass emmisions. Had about 405 peak hp. BIG DEAL.

riceracing made over 450 RWHP with a TO4B. soulassassin makes 550 RWHP with a TO4R.

T&R Racing's car has a moderately sized turbo and it runs 10.5 1/4 miles.

I am not going for the biggest turbo I can get....
I want the car to be a dependable 400 hp daily driver....
That would stomp the crap out of about anything that pulled up next to me on the street....

13BACE.... I wanted to know If I should try to run a stand alone ecu like the Haltech, or should I run a piggy-back sysytem with stock computer???
Again,What are the best electronics to run the T04 ???

The piggy back stuff will work with a TO4, but for the price of all of that you can get a Haltech E6K or Wolf 3D. A TEC II is more money, but it includes a great ignition system--no need for MSD's, etc. I'm running a Wolf 3D on my car, and I like it alot. The keypad makes it very user-friendly. waynespeed helped me out alot.

Besides the ECU you'll need a decent boost controller. I'm using a Greddy Profec, but almost anything will do. Just make sure that you have enough fuel! I'm using 4 1600 cc injectors. So I should be fine.

Between the Haltech and the Wolf, which one is better for the T04 configurtion???
When I setup the new motor, I want to run the turbo at 15 psi, does either system have limitation on amount of boost that can be used???
I also wanted to know what is the best fuel pump to use for the T04??

With the 3 bar map sensor the Haltech E6K will read up to about 30 PSI. A Wolf 3D will read up to 21 PSI, but it can be modified to work with a 3 bar map sensor. I have a Wolf 3D running 17 PSI on pump gas with the ND pump Jason sells.
