I know that Tial makes an ecellent wastegate, and i am planning on getting one (unless I get bad advice in this thread).

RICE Racing is making me a custom manifold, and he needs some specs for this gate. I was wondering if anyone on here knew about the dimension's, hole sizes, spacing and thread specifications for it?

Thanks for the help,
Joe

 

Tial sells the weld on flange for exhaust manifold. Buy the size to match your wastegate valve. If you have a 46mm valve, you will buy a 46mm flange and make the wastegate pipe from the manifold with at least 46mm ID piping.

 

thanks

 

The waste gate flange has a recessed lip for 1.5" tube, tubing is always OD, so make sure the tubing is is 1.5" OD, pipe is nominal ID, not 46 mm which is the size of the valve..Max
