Its a little annoying, but the way the car pulls when its on the boost makes you forget...hehe.

What does that monster run? I guess the point you are making is that the smaller turbo would come right back up as soon as I shift verses the larger turbo taking some time. Hopefully the added power the turbo makes will offset the drop in boost. I think I'm starting to get it. Wooohooo.

another solution is to run nitrous on a window switch to help spool the turbo.. bring a small shot on early ~3000 and cut it off around 5000 in first gear and later in the higher gears which generate more load and better spooling characteristics.. should help spool the turbo in the lower gears better where the rear end gear reduction limits load for spooling... and the big stuff 3 surely has the capability to run the nitrous on a window operated mode.. if not, several companies make them.. mallory, jacobs electronics, MSD etc...
Jose,
you said the GT42R was the same as a T76GTS? I am looking at the specs of the turbo units and they look no where near similar in comparison.. mind explaining it a little better? perhaps the site I'm using for my info is incorrect? just trying to make some sense of all the different explanations.. thanks in advance man!

Chris the GT42-76 is the same as a 76GTS. The wheels are taken out of the GT42 and machined into the 76GTS. A standard GT42 which is classified as the 102mm, is a measurement taken at the exducer. In reality its a 74mm inducer. So its the same basic turbo as the PTE-74GTS. Its just a number game....hehe.

This will help you see what the difference is. From Left to right PT94, GT47-88, PTE-88, PTE-66
First 2 on the left are T6 flange large framed units. The PTE88 is a T4 mid-frame unit. And the T66 is a T4 small frame unit.

X2C went high 8's with a stick and a large frame innovative 88 into a 306 inch small block. I think a large frame 88 would take you there, but I would start off the bat with something bigger like a GT47-88. We run that on a local dudes car and it makes some stupid power.

This is all fine and dandy... the power is there to make. My main concern would be running exhaust. Those T6 frames have gigantic exhaust requirements... If you require streetable, also take into consideration with a large frame turbo that your probably going to have to dump the exhaust, because theres no way in hell your going to run a pipe like that anywhere near the K-Member...

What spool up?
Who says you have to let off the gas between shifts? Make sure you are strapped in tight, and keep the right foot to the floor. A dump truck clutch is probably necessary.

A T56 would last maybe 1-2 passes...lol. I'm sure if its a G-force built unit at those hp levels it would last maybe a little while, but even then, the amount of shifts are numbered...hehe

The T76GTS and PTE88 are the exact same on the compressor cover. The only difference is the exhaust housing. Which you can see in the picture I posted above. Look at the exhaust housing for the T66 (which the external dimensions are the same as the GTS exhaust housing) and look at the PTE88 exhaust housing. You can definitely see the difference.
