Renasis swap?
Does anyone know if it is possible to put the new renasis engine in a 2nd gen? Or where you could purchase one of these engines? (besides in an rx8)

or
Visit www.mazdatrix.com and price out all new parts/seals and assemble it yourself.

yeah but the engine costs more than the FC? If you really want to do this swap. Finance one get full coverage and strip the drivetrain and report it stolen. Only way to do it. Or shell out 8grand for the motor.

The guy bought an Rx8 - pulled the engine, and is dumping a 20b-t in there.

well, the engine i have right now has about 175k on it and its starting to put out a little white smoke so i was just thinking why not go for the newest technology? Cheaper yes but better i realy doubt that. I could probably get maybe 200 hp out of a worked 13b vs the stock 250 of the renasis and it gets better milage and emisions too. Id bet with a little work the renasis engine in a 2nd gen would take a stock 3rd gen without the trouble of a turbo

Well swapping the "Renesis" would not be for the faint of heart. I dont think the motor mounts line up, and good luck hooking up the wiring. Oh ya and the throttle is drive-by-wire so there is no throttle cable, the throttle is monitored by the computer.
It would probably be a better idea to just swap the short block, and put your intake manifold on it aswell as the RX-8 exhaust manifold. I dont think this would mess up the ECU or if the intake manifold would even bolt up to the motor, but this is a motor from 2003 going into an 80s car, so good luck.

Amen Scot...I'm not one for turbos and all, but still it's kinda smart. Not to mention you could just use some of the renensis technology and remember it's still just a 13B with the same inards (new rotors...higher compression) and 30% larger ports. If you do the same to a 13B DEI you'll get results that are the same if not DAMN close (or better)...and it's EONS cheaper. Then again, some people just want to be original

hahah yea i was just at the dealer and the rx8 is going for 35 grand.... i dont think i will be seing that in the near future but as for the 5 g engine on ebay... realy tempting, if only it came with the ecu and all the other stuff i would need, i wonder how the trannys would bolt up... anyway im going to have to hold off on this one until i can get a lil more info.

oh yea and what doesnt make sence? the technology in the renasis engine leaves the 13b in the dust, they finaly REALY figured out the rotary engine, and your right about the ports they are on the front and rear on the block as opposed to the sides
