How much horse power Iam expecting out of an Street ported...re built 90' Turbo 2 JDM engine.. Using S4 intake, stock turbo, stock primary injectors, GSL-SE secondary injectors, Wolf 3d ver 4 and 2 1/2 exhoust to a R1 Borla.

 

250 at most?

 

Yea, 250 sounds about right. If I were you, I'd run 3" exhaust. Why the S4 intake?

 

Isnt the s4 intake beter cause is shorter and it flow better..... how about if I step the boost up to 12 pounds how much then?

 

I was expecting 300hp .... how can I achive this with out taring into to motor.

 

You'd be hard pressed to see 250 @ 14psi

 

300hp would be pushing that 550/680 combo way too far, if they ciould even support it.

 

Well I will have to get bigger injectors. My goal is 300hp. Any other changes I should make to reach this goal?

 

hybrid turbo, 720/1000 pri/sec, s5 UIM, fmic and 300 hp aint a problem with proper tuning...

 

Now thats sounds great I'll have to look for a turbo and the injectors. For right now since Iam almost done with the project I'll run it like it is. Just to see and feel the difference between 250 to 300hp on a first gen.

 

Don't forget about fuel!

 

I've seen it, on a rebuilt stockport s4 with s5 turbo and stock intercooler

 

Stock port, stock turbo, stock intercooler? arghx, please link me, I'd like to know how to achieve 250hp on a car with the only mods being fuel + 2 1/2 inch exhaust/standalone...

 

With the set as originally posted... i'd say 230WRHP max. Try using not using a cat, advance timing and some C16 for saftey.

 

need a bigger fuel pump.......walbro, bosch.etc......... stock one cant hang w/ 300hp
