I don't normally do this, but I am changing my setup to try something new starting tomorrow and car is already on the lift. I am by no means unhappy with the current setup and it really is fun to drive, but a crack in the manifold requires a change. I will still be running a T4 TwinScroll with the same 1.00 a/r turbine housing, but I had AGP send the S366 with the 68mm turbine wheel so I can use it with my existing housing. The larger compressor goes from 76lbs/min with the 62mm wheel to 87lbs/min with the 66mm wheel so about another 100hp worth of flow. The other change I will be making is the wastegate dumps will not be recirculating, which I hate. While this will not be part of the initial efforts, I also ordered a 4.08 final drive from Jacks along with the EVO 8 5th gear set. So just to recap here are the changes...
S366 SX-E (68mm turbine option)
Non recirculating wastegates
New PCV setup with AC Delco electric pump
Changing front motor mount to something more compliant
The vband flange I had machined arrived today, but the ultra tight radius 90deg bend (0.84d) was not so "ultra" and was actually 1.06d. Damn ebay scammers! Had to reorder from original source at a higher price so it won't arrive until Friday. I will focus on mounting the Delco vacuum pump until the UTR 3" bend arrives.
