Okay I was doing the turbo calculator thing..I understand it okay enough but I want to make sure I was correct..so could someone (who knows what they are doing ) help me so I can pick the right turbo I plugged in every hing but Im not sure I I am right so im turnng it to the pros..Here are the facts the motor is a
LS 1.8L
the assumed HP target is 350HP..
the VE im assuming 90%,
the PSI im boosting is 18 with a 2 psi loss
Im assuming max torque at 5000RPM
Im assuming 7200RPM
Im assuming 13.1 Air fuel ratio
What I need is someone to crunch the numbers if they have the calculator of have it calculated already for a LS with stock rev limit or advice...

 

i have tool'd around with the turbo calulators in the past a little. They are a little hard to get used to if you want to do things right.

Oh and your AFR is wayyyy to lean, that looks like an NA AFR. Look more around 11.8-12.1.

Sorry i couldnt be more help.
