What performance gains could I see? Or is the upgrade just for exhaust temps. Would it increase spoil time
Thanks
Do you guys offer rebuild for the 38R l need the bearings
Hi everyone at Turbo Lab.
I would like to have my 99.5 GTP38 exhaust housing machined out to the larger 69.8 / 13.38 wheel. If I go to the larger shaft will I have less boost? less volume? at lower throttle levels like traveling down a flat highway, no wind. Can I just send my exhaust housing? Do you need me to buy and send the shaft also. Another option you might offer but I dont know so I am asking. Can you turn my turbo into a GTP38R so I can use the 11 blade 66/88 compressor wheel? I have the 66/88 compressor housing mod.
