...dependent on what you want. I will talk to vendors and individuals to get a feel for turbine A/R...
Tiago i saw you made 335/400 with the TO4. What did you end up keeping the t61 or the TO4? The goal is around 350rwhp for this 3.8. I figure pushing it past 8psi will ruin the auto tranny. I figure the rear end will hold. Tune and proper fuel are already set.
Should I go with the t61 like you had and up the boost. Looked you made good with 290/375 from just 5psi. Where can I get these? Ebay is mostly junk.
edit: watched it again and saw your runnin the MP T70 (Specs/Spool?). Think that would suite me well with stock heads/cam? Owner just wants the STS kit and a stock top end on the 3.8

The MPT70 is the best turbo I have employed on a V6 car. It fits a stock motor great!
all are master power turbos. Looking for good spool on a rear mount app and around 350rwhp at less than 10psi.
TO4E 60 Trim P-Trim: turbine A/R .70, Compressor A/R .50 (T3 inlet)
TO4E 60 Trim P-Trim: turbine A/R .68, Compressor A/R .50 (T4)
T61 O-Trim: turbine A/R .68, Compressor A/R .70 (T4)
T70 P-Trim: turbine A/R .70, Compressor A/R .70 (T3)
TO4E 57 Trim: turbine A/R .70, Compressor A/R .50 (T3)
T4 vs T3 important?
If not ill just go with the mpt70 with .68 a/r

Still interested in how the above turbos will work. Particularly these:
TO4E 60 Trim P-Trim: turbine A/R .68, Compressor A/R .50 (T4)
TO4E 60 Trim P-Trim: turbine A/R .70, Compressor A/R .50 (T3 inlet)
TO4E 57 Trim: turbine A/R .70, Compressor A/R .50 (T3)

But I think we could squeeze ~600 rwhp out of it on 116 and 20 psi. They are stout little motors.
