I was wondering if anyone here has installed the Greddy turbo kit with the intercooler and what the horsepower gains were. I have a stock 00 Si and am considering the Greddy turbo with the intercooler. Does anyone know what new gains will be. Also, would I need a blow off valve or is the wastegate on the turbo enough?

 

You'll need a bov...



GReddy Turbo Kit at 5psi --> 4.5psi
2.25" --> 2.5" custom downpipe
Aftermarket cat --> 2.5" custom exhaust piping with Magnaflow muffler
Hondata 3b with P28 ECU
440cc injectors

I want more power though...

I agree.

 

doyou have the intercooler with this or is it just the turbo? why only 5 psi? i thpught the greddy came set at like 6 or 6.5 psi? have u ever ran the 1/4 mile? how much was your Hondata 3b with P28 ECU? did u ever dyno with just greddys stuff and not the hondata?

Yes, I have an intercooler with this setup. 5psi, because I bought a used Profec B and it wasn't working. So I decided to stick at 5psi for now.

Nope, never ran the 1/4 mile...the Hondata 3b and ECU cost me ~700 bucks.

I did dyno the car bone stock with just the GReddy stufff...everything else was left alone...exhaust...blue box...etc.

 

do you have the dyno with just the greddy and the intercooler and the blue box and not the hondata? i called a place in CA today and they told me 75HP with the turbo, 15 more with the intercooler and get a blow off valve and a turbo timer. the boost was at 6-7 PSI. I get about 245 HP or so. does this sound correct? he also said a new exhaust too, but i dont want to sound like a freakin weed wacker. what do u say to the reps claims?
