I am running a
ERL superdeck 1 block
87mm bore
9:1 compression
stock cams
Skunk2 intake manfold and throttle body
Love fab manifold
hondata s200

and currently a Garret 60 trim .63 a/r upgraded to ball bearing

i am wanting to stay on pump gas but push high 4XX's whp. would it be worth it for me to upgrade to a GT35r .63 a/r?

 

I have your same setup with ITR cams and built valve train and I am hoping for low 500whp. Last time I hit the dyno alls I could hit was 444whp but this was on bad rings (low comp) and bad guides. With the cams added and ring gap and guides all new I hope to hit 500whp on race gas no prob with the .63 a/r. GT 35R

 

sounds like an h series.

I would say a 35r is perfect for ur goals.
