[JeanDSM]

I already have a used To3/ To4E Stage 3 50 Trim 50a/r .63ext.

I bought it used and iim going to install a rebuilt kit pretty soon and want to change my compressor housing to a 60 A/R one. My goals are 300-325whp at about 20psi for now cus i only have a safc to tune. Later on the summer i will get dsmlink and if everything goes right i will have a Buschur racing Stage 3 block and head with 272 par of cams. Then ill be looking for 375 plus reliable whp. Witch of these compressor wheels will be better for my aplication? 50, 54, 57, 60 or 60-1. Also is i upgrade the compressor housing for a .70A/R TO4S one. what will the performance will be? Will it fit between block and stock radiator with stock fans?

stick with the 50 trim. it can do that on pump gas. a buddy of mine who used to live here made 397 to the wheels on 19-20ish lbs of boost on 92 octane. it was tuned on an AEM and it was on a mustang dyno. it was also a full garrett 50 trim set-up purchased from AGP. good luck on your quest! do not get the to4s housing, as it is not needed! i would suggest a to4e housing though...
