wastegate??

hey, just wondering wat is the right size wastegate to be using on my ca18, its gona be runing about 20psi thanks

Any wastegate can do it.

Only people wishing to minimise boost levels are concerned with wastegate type.

Any boost controller will happily wait until 20PSI to send air to the wastegate for it to open.

well if you're running huge turbos you might need a bigger one to flow the exhaust without boost creep when they hit the point they want to keep boost at.... but most of the time the built in one, or pretty much any external one, is going to work for a CA. This isn't a TT 'vette.
