what is the max boost yoy can run on a ca18det?

 

Moved to Turbo section, please post in the right area

On stock internals, id say 20-22PSI with the proper tuning and parts. IE upgraded fuel pump, injectors, FMIC, turbo etc

 

I was told 16psi with a stock head and full upgrades including injectors, on a stock CA you don't want to go above 11-12. I'll double check though.CA's are extremly rare, extremly on the east coast, i'm looking into one. If you're looking for crazy hp go with the Sr.

Dr.

 

go with RB

 

If you are crazy for power, go RB, those extra cylinders do help. Look for boost bo on the CA section on the Nico forums, he is pushing 400 something on a stock bottom head, Im think in the 20's of boost. That is with some serious engine tuning though. He's getting me my engine, in fact.

 

i have the ca18det in my car and have a front mount, fuel upgrade, bigger ingectors, 3in down pipe, the greedy e01 and am
running 11.5 psi. just wanted to know if i could go more.
