I saw a video a while back about someone who basically dropped an RX-8 setup into his Delorean. He even put a turb on it... the car ran pretty good.
I'm sure there's a way it can be done... but after all the fabrication and work... will it be worth it?
The RX-8 is basically the most powerful stock "RX-7" ever made... and how quick is it? Mid 14s in the quarter?? The car is about as light as the Fiero is....
I had a 1988 Mazda RX-7 Turbo-II with the 5-Speed. It was loaded, black inside and black outside. Factory CD player, power moon roof, the rear shock tower speaker option, black leather seats, the car was totally pimp... but I kept it all stock, and that car was really pretty slow...
off the line, my 87 Fiero SE / V6 would blow it away.... and it wouldn't catch up to it until my V6 Fiero was already doing about 45 miles an hour... and then.. it wasn't exactly blazingly fast... the car was in great tune, only had about 1/4 of a 100k miles on it. I guess / figure it probably ran mid 15s in the quarter.
I say, with the money you're going to spend... you might as well go with a GM motor and be done with it... you probably want to be spending more time showing people your tail-lights, than you do showing people your engine bay....

the Series4 TurboII's arent that great but when you get into the Series 5's you start to get into some power. a series5 TII should turn a low14 to high 13 pass stock. the na GTU cars turn mid-15's and they are SLOW but the TII cars are much nicer. it would be very well worth it because the 13b is a well proven motor to make some ponies. there are even kits that will slap a T76 on it stock and that in a fiero would be INSANE!

I don't know too much about the RX8, but I'd be suprised if it makes more power than the 3rd-gen RX7's of the mid 90's. They were available with twin turbos, and crazy fast.
As for a stock V6 fiero blowing away a 2nd-gen turbo RX7, I call BS. I owned a naturally aspirated 2nd-gen, and I think it was dead even with the 4-spd Fiero I had, and would probably beat the automatic Fiero I have now.
REGARDLESS, while it might be doable in a Fiero, there are MUCH easier ways to get more power than a typical rotary engine will give you.

Keep in mind that while thay do produce a high HP numbers (theoreticly the number in infinity, just limited by the durability of the parts themselve and THIER limitations) thay are nothing on the TQ bit, and we all know that TQ is what moves, and wins the race. That is one of the reasons most rotary engines are tuboed, if they were not at the time the owner bought it, it is the easiest way to produce the TQ that the engine is lacking. Not sure if a Fiero 4spd can beat one off the line, but if it can I would not be surprised since rotary engines need high RPM's to get any real TQ out of them where as a pushrod engines basicly produces TQ at almost idle.

Call it BS or not... my RX-7 Turbo-II was not THAT fast.
People seem to have greatly misconceived ideas about what these cars ran in the 80s.
A Naturally Aspirated RX-7 from the 80s did NOT.. by any means run mid 15s in the quarter.. they ran flat 16s all day, if even that.
A Toyota Supra from the mid 90s... people seem to be under the impression that they ran 12s, or even 13s stock..
While I'm sure it's not hard to get that out of them.. STOCK, from the factory, the last generation Toyota Supra never made it into the 13s in the quarter.
The Fiero, almost typically ran 16s, with the exception of the 85 GT 4-Speed and some of the 5-speed V6 Fieros which would often run in the mid 15s.
RX-7s have almost no low-end torque... all their power is produced in the high rpms.
With my 88 RX-7 Turbo-II, it had somewhat of a turbo lag.. and didn't exactly have the ball bursting acceleration that everyone likes to believe. I don't know why, but every car from the 80s.. if it had a TURBO, people ALWAYS believe that they ran 13s.
The 88 RX-7 Turbo-II, the 86-87 and even the 88 model rarely EVER broke into the 14s. I mean, right off the showroom floor, that was really quite unheard of.
The third gen RX-7s ran mid 14s stock from the factory.
Sure.. it's VERY easy to make them go faster.. but that's not how they came stock.
That doesn't mean it's less of a car, but you can't say.. "The RX-7 Turbo-II runs low 14s".
The 88 Turbo TransAm didn't run low 13s... it barely broke into the 13s.. (STOCK).
Anyway, an RX-7 motor would be nice in a Fiero... but is it worth the cost, the time, and the effort?
I'm certainly not discouraging him, I'm not bashing Japanese cars, and I'm not being a bigot by giving realistic numbers of 80s cars...
But I'm just sharing my opinion about the effort that would be required to do the swap he's talking about... just so that he can make a more informed decision.

If i do it im not doing it for "having more people stare at my tail lights than engine bay" Im want to do it to be different cause im building a 300 hp camaro and my fiero i want it to be something unique not just another V8 or 3800SC.
The only way i see it being done is longitudinally(sp) that way it clears the exhaust. I've always loved the sound and driving an rx-7 but cant fit in one as well as my fiero (leg room is awful in first gen rx-7). The motor i got is a first gen 13B so its rather simplistic and very small. Id be running the altenator and waterpump only id ditch A/c so i wouldnt have to fab up any accessory brackets. And wiring on that first gen 13b doesnt seem to have much to it.

yah most turbo cars suck from the factory i almost bought a 301 turbo trans am simply it was ghey but the cool thing was is that even when in 3rd(auto)at 75 if ya stomp it the turbo pics up an the thing just pulls and pulls

You can always use the drive axle from a Cadillac Eldorado or an Olds Toronado.... that should drop right into the back...
You'll probably lose most of your trunk.. it would be a weird fit... but it's a thought?
I mean,that is if you want it longitudinally.
You'd be better off just cutting up the whole frame and making a new car, more or less...

the rotary is extremely short so if i can find a smaller like bug or porsche tranny i may be able to do it without losing the trunk. Im still researching and if i cant figure it out to a v8 i go.

Since you're willing to go through all the work of swapping in a Wenkel into the back... why not go with a motor that produces power with similar characteristics?
You'd probably be really happy with a DOHC 3.5 or a 3.9. Absolutely more than enough low-end torque for a 2,600 pound Fiero, and all the top-end performance you could want. If you need more? Turbo charge it..
