Strange I don't consider the th400 option "pure drag". I've driven mine many times on the street w/ the auto rearend (3.76) and love it.
And I don't believe topping out at 120mph is entirely accurate. It depends on several varibles.

This should provide details:

TT transmissions can get expansive too after you brake three of them. Not to mention to built it up you will have to pay around 3200 dollars.

Our supra drag car will go 159 @ 9K with 28" tall tires. It has the supra auto diff (3.73). SW's old 95 supra would go 154@ 8500 with a 6 spd diff (3.27) on 26" tires. I have also installed a Gear Vendors unit behind a BL400 strictly for cruising. It kicked the rpm back by about 600 rpms.
All race transmissions are manually shifted.

Now thats the way to go

Also had a question on the GV setup. Have you done any WOT testing with it? Or just cruising tests?

BoostLogic TH400 for the 2jz
