Sorry about putting the pics up in separate posts but I'm doing this all from my phone and that was the only way I could figure out how to do it.

You're going to be surprised once you get good at changing spark plugs with all that stuff in the way. It didn't take me any longer than when stock after about 10 times.

Also folks could never see the Turbos because they're hidden by the motor and the log type header. Also with all that being stainless steel you don't have to wrap everything to keep the heat in. However a turbo blanket is nice to put on there. I bought a universal wrap kit from summit and used it on the hot side. Worked like a champ. I even went cheap and put that on my 3rd setup as shown in my picture on the first page.

Are your turbos straight t4 or are they t3/t4? for some reason the turbine housing looks bigger than a t3.

Im honestly don't know a lot about the turbos I know it has .63 on the compressor side and .60 or63 on the turbine side and the inducer looks to be 54mm-56mm.

Shameless thread hijack, but I have a kit that has been sitting in my shop for a while if anyone is interested I would love to sell it.

Ok, I'm assuming that those compressor covers are "b-cover" which explains why it's making me think that the turbine housing looks bigger than what it actually is. What size are those downpipes?

Didn't you end up selling that turbo kit with your engine/trans as a package to somebody a while back? BTW, how in the world were you able to changed the spark plug for #8? does'nt that wastegate pipe right in the way? I know that it's hard enough to change #8 without it like mine.

DP's are 2.5"

The OP bought it off of the guy that I sold it to. Im not sure if he ever ran it.

1/64" at a time ....dont have any plans the day you decide to change plugs. However, when I was getting tuned at GMR, the first few dyno run fouled the plugs and I thought "aw sh*t"....Joel (OFI) removed the coils & valve cover to get to #8 plug. I coulndt believe it when we had that plug out in 10 min or so.

Oh yeah it's the same one. He's been out of business for many years now. Hell of an engineer just not perhaps a good business man. He also got railed by some business partners. Lots of folks didn't get their orders and lost money because of it. He needed a real shop/operations guy to run the place. Lots of cutting edge stuff he developed but leaving folks out there holding the bag can't be forgiven.
