im am planning on running a precision 6262 @ appx. 20lbs I was looking in to running 2 38mm tial MVS wastegates just wanted to make sure they are large enough before purchasing them.

What you guys think?

Thanks,

James

 

Twin 38s is enough, as long as you aren't on a bridge-port. If so you have to move the gates to the direction of the flow instead of right angles. Those big pipes will make the turbo laggier. Ask for smaller ones.

 

Dueling gates? like Dueling banjos?..

Not a big fan of dual gates, I like to use one larger gate.
