Hi Everyone,
Don't suppose anybody knows the psi settings on the standard internal wastegate actuators for a 200sx (ca18det) and a 300zx (vg30dett) both running garrett t25 turbos?

As far as I'm aware the only difference between them is that the vg30 uses a flanged turbo and the ca18 uses a normal turbo!? Just want to double check the pressure settings for the wastegate as I don't want to overboost my engine and blow it up! Cheers in advance.

IIRC std boost on the CA18 is 6-8psi.

Yeah I thought it was about 8 for the ca18, just want to double check that using the vg30 turbo won't kill it. Wouldn't have thought it would but better safe than sorry.

Apparently I can run upto 12 psi in standard trim on the ca18 before getting knock...

I run about 18!

My mates looking into tuning his CA18DET 200sx and he says 14-16psi on std trim with upgraded intercooler. So should be ok

David

Nice one guys, as I've got my nice big fmic coming today or tomorrow I'll be able to run it quite high then. Cheers,
Tom

colder plugs if you wind it past 8ish psi.the tips have a habit of melting or dropping off!
