I have been going back and forth for the past couple of months about turbos. Ive seen great stuff out of both turbos! I am really just wondering what people would think is best for my situation.

Car comes out on nice days / weekend. I want as close to 900whp (dyno jet) under 42 psi. My currently currently has a HTA 3586 and makes 770whp @ 36psi.

My car has a Shear Fab T3 turbo kit. Easiest option would be bolt on the Super 94 T3.

Option 2 would be T4 twin scroll PTE 6870? I feel this turbo / turbo kit is more superior

 

Tough call, for long term reliability I say the super 94. I was between the 6466 and 6870 till I read that the 6870 seems to only make 50 more hp over the 6466. For 4-600rpm more lag, and that's on an efficient set up, could be 1000rpm on a not so perfect set up. I'm not sure the power gain offsets the lag.

 

6466? I made 930 on AMS's dyno at 37 psi, trapped 159 mph.

T3 or T4 ? Divided? Downpipe / Exhaust size ?
