SR20 det
Ok i know im goin to catch hell from all the rotary fanatics about this, but here we go. If any of you have read any of my previous post about all of the trouble i have had my renny then you know how the story goes, for those of you who have not read them then heres the tip of the iceberg. about 4 1/2 months ago i started getting a rattle coming from my intake folowed by severe power loss, after a trip to the dealership and a compression check i was told that i had a dead engine. Lowcompression in both rotors was the case with no waranty to save me in sight. we all know how much a remaned renny cost and we also all know that there are some guys that are even in the 3rd engine club, I just couldent bring my self to spending the kind of money it was goin to take to get my car back on the road. Now granted i would have had a waranty with the new engine i just wasnt all so fired up about it. the cost of doing a 13b rew or a 3 rotor was astounding in price for the engine and not to mention the cost of outting it in the car. so I just turned to nissan for there tried and true turbo 4. It wont throw off the balance of the car by much and its fits in the engine bay rather well. this project has been ongoing for about 2 12 months now with a good but not to big of a chunk of change spent.(still under 5400$) The first thing that we did (also were all of the time has been spent) Its getting the drivetrain mounted in the car without cutting the body or having to change the steering system or stock suspenion. an entire tubular subframe (engine cradle) was the answer and its what we did. The engine is placed to where nothing under the hood with exception of the pcm that im not using and the abs block. the sr20 tranny is way smaller than the 8's so that was not to much of a problem. new transmission mount have been fabricated as well as a custom powerplant frame. the driveshaft isnt finished yet and everything is in the powder coating shop as of now. There is still a long road ahead for getting this thing back on the road as far as wiring and making a nissan motor work in a mazda. im going to try as hard as i can for now to utilize as many stock parts as i can for now mainly for budget reasons( im not rich) .I do have pictures of the progress from start to now give me a few more weeks and i will have much more to share. And last but not least, i KNOW im goin to catch hell from alot of you diee hard rotory guys and for that im sorry. But i like doing crazy things to cars and cosidering im doing most of the work and calling in alot of favors .im having a blast. Ok im done for now....flame sute on

As am I. I wouldn't do this swap, but it's your car and it looks like it's coming around and you've got a plan...definitely let us know how it goes.

I'll snap his neck.
Yeah, this looks interesting. That pic looks weird - a piston motor under an RX-8 hood! I've seen people talk about it, but this is the first one I've actually seen (there is a guy in the Chicago area that has a LS-1 in his FD, but I haven't seen it done with an 8). Will be curious to know how it affects the balance of the car. Looks like it doesn't extend too far ahead of the front axle. What is the weight of this motor vs the renesis?
So what are you going to call your Frankenstein monster?
It's not really an RX anymore. Maybe a MX-8?
Good luck!
