From what I understand, the DP Chris was working on was going to bolt up to the turbine outlet flange.anthracite said:Unless you are not using the adapter part that bolt up to the DP from your Ti
you still have a 3.5 " at this adapter.

It's funny you said that because when I bought my car a year ago I thought any turbo upgrades to the Supra were overkill!nils said:anything over 3.5" is overkill.

Richard,Lonestar Dawg said:Nils, Thanks for the info. Do you know which turbos were in place on the cars that tried the 4" DP? I wonder what effect it had to the powerband across the board and on EGT's.
Wow... finally someone who uses a 4" DP. Do you have any before and after numbers to share with us? How did it effect torque, HP, spool, etc?t88Hpower said:I currently run a custom 4" downpipe with my T88-34D turbo. BIG difference from the downpipe the GReddy single turbo kit brings.
Now I am looking for a better 4" downpipe with better fit and finish than the one we made ourselves. Any ideas?

At that time, I had the T78 kit @ 30psi, front mount i/c, VPC, GCC, JE Pistons, Crower Rods, OS Clutch, HKS 272 cams, no cats, Super Dragger, 720cc injectors, HKS fuel rail, twin in-tank pumps, race gasolene, extrude hone head and intake, bored out throttle body, and other stuff I probably cant remember.Lonestar Dawg said:Ernesto, you need to put pontoons on that car. You're gonna go flying off the end of the island right into the ocean!
You said the car put down 741 rwhp with a T78. Did you mean to say T88? If that was with the T78, what type of setup were you running at the time? (NOS, cams, intake, TB, head mods)
Take care
