Here is a quick video that I made of a GT3071R turbo that I made to replace a trask Performance turbo. The turbo i built is rated for 400 hp.
The specifications for our upgrade are:
- Comp wheel 53mm x 71mm billet 30r wheel
- Turbine wheel: 55mm x 60mm gt3071 turbine
- T2 .64 turbine housing (from nissan sr20)
- .48 compressor housing (i have no idea what this comp cover came from)
- Garrett Ceramic Dual Ball Bearing
- Trask internal wastegate
- HP Rating: 400+ Hp and 600 CFM
The previous Trask turbo specifications are:
- Turbine wheel 47mm x 53mm
- Compressor wheel 45 x 60
- HP Rating: 165 hp
It looks From this picture that Trask Performance does do garrett ball bearing upgrades, but im not sure what size. Here is a picture of a To4b cover that they used, with this cover I could have machined it all the way to a 3076 or a gtx3582r. But we were just trying to make 200 hp with our build.
