Too big for the street? How big is the compressor wheel on the T88 you have? I think it is also 72 or so mm... Not to mention, SW runs the .81 A/R which is smaller than the standard .96 A/R that comes with the T78-88.

I am going with T-66 BB .81 A/R .
reasons:
1) I wanted BB since it spools fater.
2) Big Enough to kick viper's ass with 50 shot of NOS.
3) Every one has greddy kit ( is this a reason?)

Now i hope i can keep up with the guys in Dubai :)

dude, you wouldnt need a 50 shot to kick a vipers ass with a t66. t66 should make around 650 with no internal mods.

ive noticed a lot of people having the rps kits, more then people having the greddy. i think just recently more people are opting to the greddy kit because its such a good value.

Correction, the T 88 uses a 70mm not 72, the T 72 still way bigger than the T 88.

WAY bigger? Where do you get your information? The t88 is a big, bug turbo. The cold size is just about identically sized to the t88, and the hotside is substanially bigger. You think the t72 is an 1100 hp turbo?

Dylan, it would be interesting to see all turbos in comparison with NO NOS and see what happens, remember there are a lot of things that take place like design and all of the turbo, lets see how many people here in the forum are currently using the T 72, which i have NEVER said that its a bad turbo or nothing, we are just comparing both thats all...the information above I am getting it through some research that Angel did and he has most of the turbos dimensions and stuff.

SW (and me shortly) is running the T72 with 0.81 a/r. This combo makes about 750 rwhp on turbo alone. I believe it outspools the T88 though...

Peter, no it doesnt outspool the T 88 on my knowledge...and .81 ? hrmmm, Peter also.. I would like to see SW's car run without the bottle and see how it does..see the difference with and without...should be interesting...I get full boost around 4,700-5,000rpms... with 272's and everything else..

Jesus, yea, i'm sure, he does run the 0.81 A/R on the turbine side. I believe you T88 guys run the 0.96, right? I really do think i recall seeing a T88 dyno sheet superimposed on a T72 dyno sheet and the T72 slightly outspooled the T88. I will just have to look to see if i can find it...
Shoot, we can just look at our dyno graphs at TX2K2!!!! :)

Very true...:) we will see our dyno graphs at TX2K2...I wonder how big of difference will be the weather and the altitude from there compared to here in FL....;)

Didn't SW swap out a T88 to a T72 for better spool. I would assume he researched this before shelling out the $$$$$$ for the swap but who knows, its SW.......:)

Yea, that is true, he said that the T72 gave him about 200 rpm less lag per dyno sheet at the same place SAE. We shall see though at TX2K2...

in my opinion go with neither. go to mvp motorsports. go under supras then click turbos and wastegates. if u scroll down u find the Powerhouse Racing Stage 2 Turbo Kit. the attached picture is a dyno sheet of the powerhouse setup vs. a t-78. also on this page is a dyno of a stock BPU TT and the POWERHOUSE setup spools just as fast as stock twins and will still throw down 650 easy.
