I want to convert a BVM Agg III kit to turbine. I will need new inlets that are the same diameter as the BVM bypass's. There used to be someone who made them and I'm pretty sure it was not BVM but I forget who it was.

Jet Tech Usa makes a Maverick Conversion set that might work.

Nope. That is an open install (no bypass used). I prefer to do it with a bypass but might try an open install like this one.

Larry Ross used to make components for BVM planes.

Do you have contact info for him ?

No.
