I have a custom turbo kit with a t3t4 turbo, log style manifold, delta waste gate, dump pipe, down pipe, greddy type s BOV, RC 440cc injectors, Apexi S-AFC, spearco intercooler and a greddy profec b E01. My question is...Will I be fine with just 440 injectors and a safc to tune it with or do i absolutely need a FMU or upgraded fuel pump.

 

if you run 6-8 pounds of boost you should be fine.

 

So 8 is the most psi I can push without having to install a FMU or bigger fuel pump?

 

With 11:1 compression I wouldn't run higher than that without building the motor up but that is just my opinion. You could mess things up with such a high compression.

 

Check on cybernations or on the GReddy site. I believe that you might need a piggy back for your ECU. When cybernation first boosted their RSX they had about 7 lights on the dash come on and the car wouldn't start. I guess the ECU doesn't work with the turbo without something like the Black magic ELF (cybernations) Check here and ask some questions in their forum: http://www.cybernationmotorsports.com/

Also as far boosting goes, you don't want to push more than 7 to 8psi with the stock internals. Again, cybernations sell a piston and rod setup which brings the compression ratio to 9:1 (I believe) which will allow you to set your boost much higher. If you want to crank the boost up high, I would suggest getting a upgraded fuel pump or something along those lines.

Just my .02 though

 

forget the first part, I see that you already have the piggyback for the ECU. My bad.

 

Its a base model. It has 9:8:1 compression. Im gettng a FMU put on right now. Boost kicks ***.

 

nothing you should worry about
