This morning I pulled Stein into the barn for some rework in preparation for an October 4th drag event. First item on the list is a new turbo. The turbo is supposed to be T3/T4 hybrid w/60 trim and stage 5 turbine...
Pulled out the turbo I bought and stripped the exhaust swingvalve housing off. Huh, that looks about the same size as what Stein has now... Measuring it, the exhaust turbine exducer and it measures up at 1.92". According to
http://www.turboneticsinc.com/pa_turbwheels.htm says this is a stage 1.
Grrr.... So off comes the compressor housing and that measures up as a T04E 57 trim wheel.... So it looks like what I have is a T3/T4 hybrid with a 57 trim and stage 1 turbine...
The good news is, the turbo does appear to be a T3/T4 hybrid and a T3/T4 hybrid does fit on a Stein style exhaust manifold.
So now I am trying to consider my options.
1) Send the turbo back... and buy something else.
2) Slap the .69 AR housing from the old turbo and go.
3) Send the turbo out to TU or somebody else and have a Stage ? turbine installed ane purchase a new exhaust housing...
Not sure how much of an option 1 is, it took a long time to get the turbo across the border the first time....
Option 2 seems like it will result in a turbo that spools faster than the current T3 (from a 2.2L T1 w/.69 AR exhaust housing) and would likely run into more boost creep issues....
So that leaves option 3 as about the only reasonable option... From there I just need to decide what stage turbine to get... Leaning towards stage 3 since that will more closely match the exhaust piping...
Any opinions?
Well back to fitting the new CAI piping.... Looks like I will have to order some more silicone elbows...
