I want to go to the limit with these turbos before upgrading. You and I know that we are waiting for GTM to release the T25+ housing for their new manifold so I really dont want to upgrade anything till GTM release the new technology  |
One car is 10:1 CR at 15 pounds 570-580 whp and the other is 17 PSI 9:1 and around the same power level.Consider this on my build my low boost spring pressure 10:1 CR GT3071 .64 A/R makes 596 whp 14 PSI on a Dynojet. That's Fast intentions 3 inch exhaust. On my higher boost settings I hit a wall of back pressure, with smaller turbos you will run into that wall much sooner than I have.
The T25 plus housings have been out from Garret for a long time now its the manifolds that are needed. At this point it's so late in the year it will most likely be a winter project once the manifolds come out ,the turbos are a pain to get out to swap housings.
