Hi guys i'm really new here and would like to share and have your ideas about my setup that I'm bulding on my L15A with manual transmission.

1. Wiseco Piston with comp: 9.8.1, with forged connecting rod. I would like to know how much boost can be done with this kind of specs.

2. I have bought the HKS bolt-on kit for the fit

3. I'll be using 450CC injectors and walbro 255lbs fuel pump, and my question is can you explain me a little bit how to setup the fuel system as I cant see a fuel return and how to fix a fuel pressure regulator to it.


Regards,

 

i don't think u can install walbro 255, i tried but walbro is too long, it hit the bottom of the tank, i change to SARD 260/265 (forget the fuel code)
just nice.

 

HKS turbo will be too small for 9:1 pistons.
