Wrong place to ask probably, these guys aren't going to help out much. Go to the performance section of the forum and click on "other conversions", you will find a ton of info there. I'm swapping a 5.0 into one of my sevens pretty soon. I will still have 2 rotary powered cars though.

Squeak, Suicide Girls
im a chevy guy, and i say if you want something still economical with alot of power get a 350. if gas isnt an issue get a 427, if you are drag racing get a 454 or 502. There is a sweet 427 that a shop makes its TT and it pushed an escalade, the big truck one, 0-60 in like 4.46546 something seconds, goto caranddriver.com and look for escalade it will come up as a test. it gave me the idea to put it in my nova, which will be completed soon and then everyone in my area will be destroyed at the power of the TT in a car that weighs a little more than an FB

It would have to be the IA aluminum Pontiac block KRE is about to produce with Eddy heads...lightweight and capable of 700+ HP, 650 ft-lbs of torque and runs on 93 octane with a 950 rpm idle....but what would you expect from a 550+ cid engine, eh??

V8 FB's are not Rx7's.........Its just not the same. Never will be. No matter how much power they make, how fast their 1/4 mile time is, they will never handle the same and that is the soul of any true sports car. If ya want a V8 project car get a Fiero. But, ofcourse I am one of those die hard Rotary guys that goes and gets a rotor tatooed on his body and everyone says "geez man its just a car" to........But NO dammit its not just a car
PS its amazing how many people ask me what my tattoo is....I often tell them its a cult symbol.

If you must be so screwed up to rape a rotary car by installing a V8, at least put in a decent one: Lexus, Audi, TVR... But hell, not a pick-up truck engine, ok?

No you got it all wrong. If you go with a V8 which we will have to disown you after you should go with a small block 400 out of a GTO. Do alittle work, and you easily got over 600hp. But you also have to have the $$ to afford the gas.

If you're going to install a larger, heavier engine, I'd personally do a 20B. More torque AND it's a rotary. It can also be done for a lot less money than you might think. How do I know this?
Reciprocating engines don't turn me on. I'd never put a V8 in an RX-7.
I bet a lot of the V8 RX-7 people here already had some prior V8 experience. It's the only logical assumption I can make. Otherwise it doesn't make much sense to swap in a V8 when you can great power out of a rotary. Even so, why is the rotary such a foreign concept to these people that they can't make the power they want without swapping engines? Are they too old-school (old/set in their ways) or dare I say dumb? Is it a cost issue (hard to believe since rotaries are so cheap to build for power)? Why then are there so many piston powered RX-7s on eBay? Maybe the swap isn't as cool as they first thought. Or maybe they're trying to recoup some of their expenditures? Meh, I'm probably too dumb to figure this one out.
I guess it boils down to personal abilities/preference in the end.

No, it's usually cost becuase they have some raggedy ford or sbc lying around or can score one for $300 and they'd rather go that route...what does a rotary rebuild kit cost? If it's $300, then they really have no excuse except the very task of rebuilding the rotary means buying some tools or renting some tools you would never need for a boinger rebuild and then you're talking more money again...

I've seen a 189ci block do 10sec quarter mile in an old Holden EH which was street registered. You yanks always think bigger is better. Not true! Unless you plan to drag other top fuelers, wtf is the point of putting a huge block in the rx7? Your never going to make 600hp work properly unless you start doing some serious modifications and then its gonna cost a bucket load. Just wack a turbo on the 12a or 13b and enjoy!
