Put some ARP rod bolts, new rings, some cleaning and gaskets and its back ready to go once my clutch arrives. I am going to add an W/A intercooler, VEMS, soon but getting it running first. I highly recommend this route, the car is proper fast.
Parts:
Garret GT30R 3071
Protomotive RRFP
Protomotive Stage 1 Chip
Protomotive Charge Pipe (no intercooler)
Rarely L8 Muffler
TiAL 46mm Wastegate
Oil line to turbo
Good luck!

Nice numbers for non-intercooled! But, I can't help but think, for a little bit of money, how much more power you'd make with one. I paid $500 for a V8 designed intercooler from Treadstone. It has a 15 degree raked back inlet (was made to go in front of their radiators) that I cut off, and rotated 90 degrees aiming towards the throttlebody. Then, I removed the outlet and mounted it 90 degrees on the outlet tank and welded in a plug to where the outlet used to go. Did all this a MIG and spoolgun. Took about an hour.
Or, you can get a ridiculously cheap one from CXRacing. I bought one initially, it has a 5" core!!! It was only like $215. It was a horizontal flow, and in my mind, was going to be a restriction (not likely at all, after seeing high power cars with this design), so I opted for the vertical flow (Treadstone above of course) that every 911 turbo aftermarket house uses just to be safe. Was going to have to rotate the left tank 180 degrees, was the biggest hurdle too.
