Thanks Ted and Cal for the heads-up on the turbos. I am new to the buick thing. I have went to BG nationals last 2 years and going this year but only on saturday. Had my GN 3 years and T type for 2 years. So I will need help sooner or later from some one that has been there. The first time I drove one WOW I was hooked . Got to drive them off the transport truck. I was a GM technician for 15 years own a shop now . I have two boys thay are hooked too. The GN is mostly stock. The t type has a 274 8:1 TA block engine with TA SE heads race port, solid roller cam 226/226 ,roller rockers , TA ss 4bolt headers, bigstuff3 ,4L80E trans, 4000 stall 3 disk lock-up converter , 4 inch rjc intercooler , ported champion intake.Cal is right on target. He sent me the 47/88, 47/80 turbos to test. I had a Jacks old 76 turbo on the car prior to this, the 47/88 was much harder to spool in comparison to the 47/80, both were night and day from the T-netics 76. I have a 42/76 turbo I got from Cal also and it really is a great turbo. I now have a 88/47 turbo with the new motor and it has ran 163.31 in the 1/4 and 131.15 in the 1/8th. Unless you plan on making big power I would run the 76 also like Cal said. The 76 is capable of 8.8x at 154+ I predict at #3400, but you will be pushing the thing hard to get it there, but the street manors will be much better.
That is a very good turbo. makes good power all thru the rpm range.
Spools good if you get it tuned right,I went 145mph in the 1/8 and 175 in the 1/4 with it and think there was just a little left in it.

P.S. update your sig!!![]()
What is the difference between 47/88 and 88/47 (TED saw you posted it this way?)
I know the 47/88 is "usually" a T6 housing.. is the other a T4?
Thx!
