neat but odd...

was that really worth it with all of the horsepower options porsche has? I think it is neat in a 914 that came with about 18 horsepower but 911's can get to 400 a lot easier than swapping in rotary power.... Differerent...

I had a Chevy V8 powered 914 at some point. Had a lumpy cam and sounded like a stockcar but body was stock ..350hp at 2200lbs...

I dont believe its as uncommon as youd think. You can buy the adapters for the transaxle. Theres a guy on rx7club.com swapping a 3 rotor into a 77 widebody 911, thing is going to be amazing.

Those aren't 13" wheels. I'd say they're 15's. It looks like, and I could be wrong, but it looks like the front are a shorter sidewall than the rear. But they aren't 13" diameter wheels. 295mm is a little over 11.5" wide. Those look like RSR Fuchs wheels, and the widest I ever heard of was 9" fronts and 11" rears. And probably worth more than the car at this point. The rears could easily be a 295 tire on a 11" wheel. His tire choice is seriously limited

That's a nice looking car, too bad it's got a rotary, but I'd like to see pics of the engine stuffed in there. I'd be interested to know how he mated the rotary to the tranaxle. Usually when one stuffs a different motor in a mid- or rear-engine body they use a FWD motor and transaxle because that's all that will work.

But regardless, it's a cool car. I'd think it was cooler with a flat 6, especially with a turbo, and find it hard to comprehend how someone would think a rotary would be an upgrade to the factory Porsche powerplant. But if it's there and it works, it's cool.

Significantly less weight and better exhaust flow for a turbo isn't any sort of upgrade? It would hardly be "stuffed" either. The 13B is tiny.

if I remember correctly a rotary is about the same weight as a smallblock chevy.... anyone know?

i would prefer a Renegade 911 with a 427 Z06 engine in the back...

I think the rotary is around 250 lbs.

The LS2 weighs about 450 lbs.

Both according to a quick google search. Can anyone verify my numbers?

That rotary is fully dressed (oil and cooling systems). I don't know if that's the case for the LS2. Rotaries produce FAR more hp per pound of weight than a comparable piston engine (at the expense of efficiency).

Rotary power/weight isn't as great as it's made out to be. Typical LSx powered FD RX-7 is 50 to 100 lb. heavier than stock, with similar weight distribution.

linkie to LS1 vs. FD 13b: http://sportcompactcar.automotive.co...car-stats.html

They put the LS1 at 487 lb., FD 13B at 425 lb.

'93 RX-7 w/ some mods: 2660 lb., 49.2F/50.8R
'93 RX-7 LS1 w/ mods: 2737 lb., 49.9F/50.1R

I love the rotary concept of small/simple/lightweight, but the reality doesn't live up to the hype.
My money's on an LS V8 as far as engine power/weight goes, stock vs. stock or modded vs. modded.

I'll take your word for whether that motor is good or not, but from a 911 perspective that car is a complete piece of shit, no offense. It's an abused older 70s car with horrible paint, body kit, interior, and looks like a hacked targa.

Pics of my friend's 912 => 913b:



Linkie to build thread: http://bb.bbboy.net/vwengineconversi...m=1&thread=249

Weight: 2317 lb. with half a tank of fuel, reportedly similar to a same-year 911.
Very cool car, Carl did a GREAT job with it! Also shouldn't offend Porsche guys as it was only a 912

Again, I love the concept of the rotary (owned an FC) but the light weight is often exaggerated...

A 13b with A/C, alternator, etc weighs just about 400 lbs. I think it's like 390 lbs. or so. More with turbo and plumbing.

Think about it. A rotary is pretty much a solid chunk of metal with small internal voids. A V8 is pretty much a block with large cavities inside. The physical size difference is deceptive. And a pushrod V8 is a remarkably compact machine for the power it can generate.
