I was able to get a few things done this weekend. Got ptv clearance verified one final time, reinstalled valve springs, installed pushrods/torqued down rocker arms, replaced gasket/torqued down valley cover, new knock sensor harness, replaced intake gaskets...the long block is finally ready. I'm shooting for having the hinson swap kit installed by next weekend, maybe get the clutch and fly wheel installed. More pics to come soon

It most definitely is going to be fun, friend has an ls2 rx7 making around 450rwhp, raced my ls1 240 making 490 rwhp and it was the best racing since we're both clawing for traction, 4.08 for the 240 not sure what the rx7 has but I know its close to a 4.08 gears and both running a t56 works great on the drag strip but a smoke show on the street, I usually launch in 2nd on the street, unless I have my slicks on.

What exhaust manifolds are you using on it? Personally, I would suggest JTR headers (JagsThatRun). You will have to clearance the lower firewall, but I think you run into that with any of the aftermarket longtubes. Also are you using manual or power steering?

I just recently got my hands on a set of JTR headers used at a good price. I'm retaining the factory steering rack; I was going to depower it, but chose not to when finishing up the swap kit. My friend has a manual rack, but he wants too much for it.

You might already know this but then again you might not. If you are using F-body accessories, you can piece together the the lower part of the f-body power steering hose on the high pressure side to the hose from the RX7 right where it attaches to power steering rack. The hard line needs to be cut and reflared. This thread talks about it more http://www.norotors.com/index.php?topic=493.0.html
The low pressure side is super easy.
Also get yourself a pressure restrictor from TurnOne Steering.

So Im bringing this back from the dead for a much needed update:
Everything is in the car, motor/accessories and trans. Cam has been installed, clutch installed, shifter, etc. After some grinding and cutting I managed to get the radiator mounted and the harness/computer ran into the cabin (passenger side kick panel).
We have been trying to make sense of wiring this damned thing into the chassis, and i think we are running into ground issues. I am installing a switch panel and redoing everything (we had tried to utilize the factory mazda harnesses running to the factory mazda ecu for 12v switched/constant/fuel pump sources). Prior to redoing the wiring, it would crank but never fire. It did not have spark, and we were losing power to the PCM when i cranked the motor. I will try and post some pictures this week.
This is now officially 13 months in the making, and im ready to hear this thing fire up.
