Hey guys...need some advice. I have the following setup:

GSR motor
JE 9:1 pistons
completly rebuilt motor
Garret t04E turbo
Vortec FMU
Zex plugs
Zex Inline fuel pump/booster

At 1/4 throttle or more, my a/f meter goes lean. Whats my problem? I'm only running 6psi on 93 octane with a bottle of octane booster in every tank. Please Help!

 

What size injectors and FMU disc are you running?

 

I believe motors generally run leaner at partial throttle...

 

Is it ok to throttle past that point? I was afraid to damage something. I have stock injectors and the 9:1 plate in the FMU...hope this helps.

 

try 12:1 disk. or use that 9:1 w/ some 310cc injectors.

 

yup, 9:1 is not a big enough disc for stock injectors. get some 310s or 440s.

 

310s or 440s? Will I be able to give it full throttle on 10psi? Do I need an intank along with my inline fuel pump?

 

i think if you ran a 9:1 disk w/ some 310cc injectors and your ZEX pump you should be good. 440cc and 9:1 might be to rich.

Stock prelude injecotrs are 310cc, pick up a set, get em cleaned, hook up an resistor box, your set.

 

Where do I get injectors cleaned and what is a resistor box? Thanks in advance! Oh yeah...what year/model prelude? Blue top DSM injectors work?
