Which / what valves?
Turbo Mini Forums

FAO those people who are actually running a 998 Turbo with a 12G295 head and Axel & Andeh.

Which / what exhaust valves are you using? are you running the stock valves or have you gone for stainless ones or something else?

Edited by Rob H on 21st Jun, 2007.

For starters I'm running the standard 1" exhaust valves.

That's on up to 12psi boost. See how it goes.

I'm using 29mm stainless valves in the high boost engine.

If money was no object, then I would probably try and find some stainless 31/26mm valves with triple groove collets and use bronze guides.

Actually, having a CRAFT moment above.

I did fit some standard unleaded A+ exhaust valves and some 31mm stainless inlets.

They are single groove collet as the picture, not 3 groove as the text.

That's the trouble with having five 12g295 heads at various stages of preparation. Too many projects.
