I have a Terry Houston 3" downpipe with internal WG that i used on my old combo, which was mostly stock with a PT51 turbo and ported heads.
Now I'll be running a Weber stroker with fully-CNC'd GN1's and a fully-CNC'd Champion intake, roller cam (218/212) and a 6765 billet wheel turbo, journal bearing.
First question is: should i stick with a 3" downpipe or go for a 3.5"
Final question is: should i go external wastegate.
I'll be running around 20psi on the street, and may turn it up to around 22-23 at the track. I expect high 10's on pump gas and low 10's on race gas. Thanks.
