V8 Rx8 conversion?

Anyone try to put a V8 in the Rx8. I like the looks of the Rx8 and think it would be a great conversion car with the LS1 or LS2. I know it would be extremely hard to find a Rx8 without a motor or bad motor.

Just curious if you could fit a LS1 or LS2 in it, I would think you could. Any thoughts?

" Any thoughts?"

Yeah, post this again in a few years when the warranties are run out on the early RX-8s. Of course by then, with gas at $6.00 a gallon, the whole V8 conversion mania will be just a fond memory.

I don't know, it may be a suprise to you but I get better mpg now then I did with the modified rotary. Although I'm not worried about gas prices like some are or else I wouldn't have a sports car, you have to pay to play. Now when cigerettes go to $6 a pack I'll probably quit that!

Yeah the stock LS1 T56 in an FD will get right around 28mpg. That has been the average.

Does the Renesis get that kind of economy? How about the 13B?

Would the LS1 fit in the RX8 engine bay? It looks smaller than the FD bay for sure. It shouldn't be long before we start seeing junked RX8s in the yards due to the engines.

Pushrod Small Block V8s are, well, small. It probably will, but I dont have the dimensions available to me.

The biggest issue would be that the stock tranny cant hold the power, and necessitate dropping in the T-56 as well.

So, I guess it comes down to this: Chevy makes great drivetrains, and Mazda made great chassis years ago, lol!
