To get a good looking dbw throttle body is $700-$800, Holley sponsored this one. I've had mechanical tb's on turbos and blowers without a single issue.

It's a 92mm. The intake can accept a 102mm but since it's under boost instead of sucking through it like a roots I kept it smaller to keep the intake plumbing easier to deal with.

A 92mm should be ok. I start to worry when I see smaller engine with the big 102mm TBs, especially when using a manual transmission. The 102s flow a lot of air at low throttle input and it becomes hard to drive from a stop. I have a customer who had exactly that issue and now that he has a stock 90mm DBW, he is much happier.

So happy you are starting to crank on this Jody.

What is the compression on the engine and how much psi you planning on throwing at it?

9.7:1, and maybe 14-15 psi max. Should live a long time.
