Hey guys, what do you think of the Garret T66 turbo, ive got a chance to get one brand new at a real cheap price so im considering it, what i wanna know, how will the spool up times be and will i need to port my engine.

Thanks.

 

i am in the same position. i was deciding on these options:

t-66
t-78
gt35-40
t04e
t04s
t51r

there was one web ste that helped me out alot. it gives about 200 cars and their setups. it is a dyno chart on all cars and it compares it on a graph. i compared the the turbo's in my list and the t-66 ran equal to the t-78 except for spool. the t88 was laggy and then you were about 600rwhp from 7-8k rpm. i also comapred the bnr stage III and the t-66 compared better in spool also. this is the right turbo for me. this turbo will max out at approx 500rwhp with race gas and right tuning. for daily driven, tune it to 380 and have fun. it is the most streetable turbo!!

 

its the most streetable turbo IMO and Jeff's at rotary power!
