wastegate

what would be a good waste gate to put on a td06 turbo or on a ct20b?

The WG on the CT20b is fine.
For the TD06, I would siggest clicking my siggy photo and talking to the guys at ATS Racing.
Tell them I sent you :)

is a td06h for an rx-7 the same as the td06 for the mr2? i dont no if it will fit cause i can get it cheap and am not sure if it will fit the stock manifold. greedy has a td06 for mr2's and rx-7's. can u help.

There isn't a TD06 that fits the MR2s manifold.
They all require an adapter plate.

I do not know if the MR2 and RX7 use the same "TD06."

ATS Racing would know :)
