^ Yes I realized that very soon after I made that post and felt like a complete tool lol ... So in order for the Rx8 tranny - FD engine setup to work, you would need Rx8 Pressure plate and Friction Disc, altho some other Friction discs might work, and the Fidanza flywheel I have works on both engines, counter weight is based on the engine so FD counterweight, the FD Pilot Bearing I believe is the same as Rx8 and an Rx8 Throwout bearing is also needed. And I am currently rebuilding my 13B-REW and porting and polishing myself, the insides of the water passages were filthy with 20 year old orange coolant / water grime so it was very much needed, something that would not just simply wash off by flushing the coolant system, I mean there were chunks of orange rust stuff.. I also thoroughly cleaned the Rotors, Irons, Housings and all seals and springs with Kerosene in the parts washer for days.. Plus I very much wanted a Large Street Port, I used Pinneaple Racing Porting templates on both the intake and exhaust ports, EP5 large turbo port template on the exhaust ports.. I will be re-using all apex, side, corner seals and springs as the engine fired right up and ran / rev'd real good I got faith in it is a good core, and if needed I will do a full all out rebuild in the future... I will be using a cheap ebay Rx8 pressure plate till I get a double or triple disc clutch and sell the Fidanza.. =D I also got faith in the Rx8 AISIN 6 Speed tranny, with the Syncro-Saver I think it will hold up to high HP very nicley, I'm still to get a short throw shifter, and IF it breaks, I will try the later 09 and up one, and if that fails, then I guess it will be big bucks on a T56 for the ultimate 6 speed tranny. I gota update and post up the latest pics of my project to my Picasa web album one of these days, link on my SIG below.. Here is a vid of the engine reving up after a 20 year off duty period, first link below. I had it idling and reving for hours, just couldn't drive it =P . Have my tune pretty decent idling and warming up and cold starts, yet to perfect it under load and WOT, and new spark plugs are probably very much needed, I used the ones from my Rx8 engine that I tuned from very rich on down to leaner AFR's..
