OK, I spoke to A-Spec and Davinci today about non-BB GT40s. I'm not positive which one I should go with, so I'm asking for input.



My setup is a 13B-RE with a 1/2 BP on it. I'll be running a divided tubular manifold with 15" equal length runners. I'm looking for the best spool-up possible without losing too much on the top end. The car will be used for autocross, some drift, and the occasional dragstrip runs.



I'm was using a Garrett 60-1 with .70 comp side and 1.15 hotside and an HKS manifold. It's nice, but I want something a little better. I just sold those, so my car is currently sitting.



Currently, the GT40 with the 88 wheel won't be available until May. (Not wanting to wait that long). That pretty much leaves my choices as:



GT40 with 82mm wheel .94 hot side



GT40 82mm wheel 1.15 hotside



Yet another 60-1, but this time with a .96 hotside.



Like I said, I'd like the setup to be fairly respnsive, but I don't want my power curve to look like most dyno queen Supras. I'm looking for something that will have a fairly broad power band. I know that Michel has this turbo with a .94, and he said he gets 17psi by 4000 RPMs. I'm hoping that my 1/2 bridge can drop that by a couple hundred RPMs.



Thanks for the input, guys!

go with the reactive racing r-85 kit. the turbo is built like a rock and will out perform the gt40. the kit is only $3100 and is hand welded by an nhra certified welder.

well, first off, I don't need a kit, just the turbo. Other than that, what's a contact number or website for them? Any idea on the cost of the turbo alone?
