new turbo and pregress pics
-
got my new turbo today, its freakin huge. Borg Warner s400, $550 compressor is a 75mm minor, 105mm major. the turbine is a 88mm minor, 95mm major. also im almost done with my wiring and have the oil pan shortened, need to cut the pickup tube next. the new intake and 60# injectors are assembled and all the braided hose and fittings will be here by friday. Also got the big cam installed last week. hopefully will have the motor back in for the last time sometime next week so i can start building the headers, thats gonna be a fun one.

yeah Dave aint got shit on me now! jk, i guess 500-550whp this year will be more than enough, should spool around 28-3400 on my combo, actually hope its a little more laggy since im gonna have about 400lb/ft torque without the damn turbo, i hope those 275 drag radials can hold alot of power.

oh, no the GTO is long gone, this things going in the Buick. 6.0L and a 4l80e is a pretty stout drivetrain, the v6 just has its limits, at around 600whp then you need to step up to the big Stage II block and thats expensive as hell, this stock motor with the turbo is good to about 550-600whp, then a set of rods and pistons with good bolts makes it good to around 1000whp, for about 1/4 the cost

jus the cam for now, like i said, 500-550whp is more than enough this year, im not even gonna paint it up till next winter, want all the bugs and shit worked out of it first. Want to do some interior and body work before i go for a 1000hp motor. still dont think im gonna put a bar in it so wont be going to the track much, thats why i went with the 4l80e, should get in the low 20s for milage, i got 24 with the GTO on the highway, similar weight and gearing.

hey dave, you see that you aint got shit on me! no but yours aint much bigger than mine. best part is for 450$ i can upgrade to a 80mm which is good to 1250hp, or an 88mm which is good to 1400hp. but, 1076 is more than enough for me. anyway thats a t6 all the way. it makes a gt42 look like a sissy girl. but you and me both know gt42's are for pansies!. haha.
Zack you need a 4 rotor p-port to even think about spooling that, you just stay with your wussy little t-4s and get ready for a ass whoopin!

GT4788 is bigger than that s400...I think your talking about either a GT4708 or GT4718, there is no such thing as a GT4788, because that would be a tiny compressor with that big of a turbine
GT4708 108mm Major 80.7mm Minor
GT4718 117.6mm Major 88mm Minor
S400 105mm Major 75mm MinorYour right that either GT47xx has a larger compressor, but the turbine is larger
on the S400S400 95mm Major 86 Trim
Gt47xx 92.7mm Major 82 TrimEither way the S400 is going to respond faster than the GT47 even with the larger turbine because of the comp/turbine ratios.... even though the GT47 has a smaller trim to help spool, yet the smaller trim hurts topend flow compared to the S400...with comparable turbine ARs
the S400 will run out of compressor a good deal before though -
It's a GT4788 is the other name for the GT4718 IIRC.
88mm compressor inducer -
Its so fucking stupid...the difference in the naming between the old T series and the new GT series
Using the Compressor Major to name the GT's and the Compressor Minor to Name the old T series....It makes a person very confused if you are not aware
and the GTXX only denotes the turbine frame size.....whatever i guess
