Default Custom Twin Turbo Dilemma

Hey all. Doing a custom TT build on my C6 corvette. Just starting the hot parts and realized the turbo's we got (used, but perfect condition) are a bit different. They are both Precision SC61's but one has a .60 compressor and .63 exhaust. Other has .70 compressor and .68 exhaust.

I also have a Turbonetics TC76 but decided not to go single. Will those two turbos fight each other and end up being useless together?

Call Precision. Buy matching covers.

What he said !

or you will have different backpressure from bank to bank which will mess with EGTs, fueling and timing.
