you don't need a DP for testing if ur motor works, just leave it open. MSA sells already made DP but I think u still have to modify ur current setup to fit it. I think a custom made is ur best bet.

I came from Zdriver.com at that time I decided I was going to swap out my 82 turbo motor to my 240z but people there didn't really help me out much. So someone there told me to go to hybridz.org I think it was Aux not sure. So I ended up here and successfully did my swap =)
