200R4 update
The crankshaft pulley arrived from March Performance. When I went to see if it looked right and everything lined up, I realized I don't have a water pump pulley other than the one currently on my 318. I found one on eBay and ordered it. I hope it all lines up. It may need a spacer according to March. Today I also ordered the 1 5/8 - 1 3/4 step headers from TTi. I decided not to use the 1 7/8 on their recommendation. I will get more torque from the step headers, and I don't have enough hp to need the 1 7/8. They tell me if I was 650hp or more they would be better, but a 500hp I am better off with the step headers. I went for ceramic with the thermal coating but decided not to go polished.
The install date is set for two weeks from tomorrow. I can't wait. I am bringing the motor to the shop next week to bolt up the motor and tranny and mark the adapter plate for cutting. I don't know if I am going to use a plasma cutter or a band saw. It's about 7/8" thick.
