Reliable as in getting more than 70+K miles out of a 13B-REW Core. Jim Lab has a project LT1 with 650+ hp estimated, so with the aluminum block V8's your not looking at too much more weight in comparison to the 13B-REW core and all the turbo accessories.
I don't like the idea of putting a V8 in a RX7 because the rotary engine makes the car what it is.My opinion.

Yawn...

Buy one first and then worry about what engine you are going to put in it.

You know the funniest thing happened... once I took the rotary engine out of my car, it still looked like an RX-7. Can you believe that? And you'll never believe this... I can still order parts for it from a Mazda dealership. Amazing! Yeah, I couldn't believe it myself.

If you bought into the rotary engine being special (different yes, special... well... whatever floats your boat) and that's what defines an RX-7 for you (although the RX-7 wasn't the only Mazda to come with a rotary engine, obviously) then that's fine. But anyone who says something as asinine as "if you remove the rotary, it's not an RX-7 any more" has a brain that isn't firing on all cylinders, pun intended.

If I buy an Impala and swap a 502 into it, is it still an Impala? Sure. What if I swapped a Ford Modular 4.6 into a Miata? Still a Miata. So what's so different about the RX-7 that removing the rotary engine suddenly makes it something else? Answer that one, and you'll prove yourself a better student of logic than I am, apparently.

The car is still an RX-7, it's just no longer powered by a rotary engine. I don't care if the R in the name stood for rotary originally or retard, which is what most people turn into when discussing this subject. It doesn't matter. The car is still an RX-7. The VIN number hasn't changed, nor has the registration, so according to the DMV, it's still an RX-7.

If you put a body kit on your car, you've made it look different, but it's still an RX-7, right? If you put an HKS sequential 6-speed in the car, it's still an RX-7, right? So if you put a 4-link and Ford 9" rear end in an RX-7 with a Lenco 4-speed and go drag racing... is it still an RX-7? According to most people who love to quote how quick RX-7 drag cars can be, it is. So if you put a domestic rear end and transmission in the car, it's still an RX-7, but if you put a domestic engine in, it's not??? See what I said above about logic...

Perhaps it's still an RX-7, but I'm sure I'm far from being alone in having the opinion that removing the rotary engine from it rips an a defining element out of it. I view the RX-7 more than just a shell or silhouette.

Maybe I wouldn't feel the same way if there were lots of Rotaries out there but there isn't and the rotary to me is a lot of what gives the RX7 its character. But then again, I don't even like the idea of going to a single turbo either

I was on European RX7 forum and some guy is custom building a 26b 4rotor in a 3rd gen.. that was couple of months ago when he got the car from japan to AU..

A very solid argument could be made for the engine the car came with, the 13B.

I love the 20B (power, torque, the sound), but there are ways in which the 13B is a better engine for the RX-7. It's cheaper, lighter, and smaller for instance.

-Max

P.S. The engine designations are in hex (base 16) format, so a 13B has 315 rotors, and the 20B has 523 rotors. Kidding, just kidding...

You know, the funniest thing happened: Once Jim spent enough money on his mutant transplant to purchase a small island and answered 10,000 flames from people who neglected to engage their brins before firing up their keyboards, he started getting a little "feisty" on the subject.

I would say that in either case, by the time you changed enough of the car to handle the conversion and not be a dangerous rattletrap, you would have a custom hotrod that was BASED on an Impala or a Miata. Hotrodding is a fine American tradition and we've never been particularly respectul of the rules that the original designers had to live by.

"10" = 2 in binary... apparently you're not one of the types who do.

Fine, I can live with "based" on... but putting a piston engine in an RX-7 doesn't make it a Camaro or a Corvette, agreed?

Funny... your response looked remarkably similar to what someone who subtracted the type of people who understand binary (1) and the type of people who don't (1) from "10" and got 8 might say...

Next time, throw in a "j/k".

what defines a car? hard to say, but i know things that don't define a car

- what wheels it has
- what color it is
- whether it has leather or clothe seats
- etc.

and i think it's generally accepted that the engine is one key thing that defines a car...you think of 911.....flat 6, or a viper, v-10 or a rx-7 rotary. i mean come on, if i were to stick a honda 4banger in a viper would it really be a viper anymore?

just my humble opinion...go ahead a ruin a perfect good car ;-)

Yes, it would just be an I-4 Viper....but in our case, a V8 RX-7. Once he's not making the car worse, I don't see how he is ruining it...at the very least, he's not blowing rotaries. Anyone who knew RX-7's in the first place, would more than understand that it's not something normal. Besides, if it's not an RX-7, then what is it? (and PX-7 is lame...)

Maybe you should get the 20B with the triple turbo on it haha. Funy thing is I had some moron say he knew a guy that had that in a 3rd gen. And also telling me that RX7s have T3 turbos for the stock ones on a FD ahh funy times.

Yes, there are people who believe the tauruses on the oval track are the same ones they have in their garages.

"There are two types of people in the world: Those who understand how to post sarcastic comments, and those who don't..."
