I have rotors in my 7 but im not against pistons. I would probably go LS2 over anything else, maybe 2JZ. Here is a pic of my engine bay. Your pic made me not feel so bad about my dirty engine bay. We both need to take the time to clean lol.

I don't know why you you want a Nissan engine or Toyota (lexas, same thing) they are not any more reliable then rotary's. In fact I would not use either if I got them for free. Jaguar being owned by Ford would make sense, but their engines aren't know for reliabilty. Corvette looking verry similar to the RX7 seems to be a very good match especially considering a stock engine has the HP we've wanted to acheive with the now outdated rotary. The GTO engine is a waste in that extremely heavy Aussie body but works well in the FD.
We will see more and more of these conversions becuase the cost of the engines has doubled but the value of the car has decreased in half. Moreover, the conversion cost is about the same as I hate to use the stupid term of "fully built" (as opposed to a partially built engine?) so lets just say "fully modifed" single turbo.

Single turbo rotary here. I personally dont like anything about american v8's. I dont like how they sound, i dont like how they are built. I dont like the lack of advancement in technology. I.E. the fact that they dont use coil on plug. They have single runner intake manifold designs, pushrods (seriously? still?), not very well balanced, not a very good hp/displacement. I dont like the power band. I.E. too much low end torque. Lots and lots of things. I picked this car because of how much character it had. Not how many pistons. And after all the r in rx7 stands for something and its not part of your brakes.

same here.
Don't be so quick to dismiss pushrods.
The design makes for a very compact motor with a low CG.
Don't get me wrong, I love my rotary, but dismissing the chevy small block because it has pushrods is a mistake IMO.

Dismissing an engine because of push rods is like dismissing an engine because it doesn't have pistons. they both have their pluses and minuses.
I honestly don't care what people have in their FD. Have whatever the f**k you want. It's all the same to me.
FlaoFD, I think most people have rotaries in their FDs. It's easier to fix/get a rebuilt rotary than it is to fork up the cash for a V8 swap - and it's obviously beyond a lot of people's patience and technical abilities. I'd say that the results are on par with what I see at events and meets.

Single Turbo Rotary here..
I agree that your results will be pretty skewed. Most in this section have the rotary. Just like if you go on the V8 rx7 site most will have a swap.
Personally if I was entertaining the idea of a swap, it would be the 2JZ, or the RB26. Both are bulletproof and can create lots of nice, usable power. And I like turbos... With a turbo V8 you have gobbs of power, but it is not very usable. Traction seems to be a problem with the light chassis on the FD..

I've always been a rotary enthusiast, but here's the problem.
I'm active-duty Navy, stationed in San Diego. My car is in Georgia, and has been for over 2 years now.
When I first bought the car with a blown motor, I traded my (at the time) Tech2Motorsports 2JZ Swap Kit (Worth $2,500+) and paid $1,000 in labor for a 13B-RE.
Turns out, the wastegate diaphragm had a small hole in it, causing the car to overboost to 18psi during the initial dyno-tune. The motor blew the next day even after the diaphragm was fixed.
I didn't even get to drive it!!! :[
So 6 hours and $1,300 later....
Finished product:
I made 326hp/296tq @ 11psi and 387hp/251tq @ 15psi on 93 octane.
The motor blew during my New Years visit, and THEN I got scammed out of $500 in trying to buy a replacement engine.
THAT'S why I'm now at the "You know what? F*ck this..." state...
That, and my brother is my star mechanic in Georgia..but once I get the car shipped out here to San Diego, I won't know any mechanics, and I don't know that I make enough money in the Navy to afford another engine or two...
That's my story and I'm stickin' to it.

V8s know their own tune, and I hunt Mustangs, F Bodies (and Porsches) only with a rotary powered FD. An FD with a Chevy motor is a novelty I suppose, but I'd just as soon have something like a Mallet Sky instead, or even a C6. A V8 tune coming out of the single tailpipe of an FD is just wrong.

To say they are no more reliable than a rotary, but add a turbo to the rotary and it's a whole different ball game (I don't like to admit it)
but everyone is entitled to their opnion.

Yep there are those that keep rebuilding rotarys or keep installing used engines and yet never pin point what made them blow in the 1st place. The supporting commonents 99% of the time are the cause. I know of an sequential turbo 330+rwhp Fd that got rebuilt at 90k. This same engine is still running perfectly and chassis now has 180k on it. The car was built and maintained by Rotary Performance in Garland Tx. As you said "Once set up properly (with reasonable boost) they can take a beating"
A V8 tune coming out of the single tailpipe of an FD is just wrong.
