A little while back, i had the idea of installing a 13b twin turbo rotary engine in a fiero. one reason was because it already comes with a twin turbo setup, and another is because of the high rpm range. I know that rotary motors have problems with burning oil, but has anyone ever thought of doing this engine swap?

i dont know anything about these engines, but i remember reading that it wouldn't work, i dont remember why exactly.. something to do w/ the headers location? Its a little vague, someone else will chime in.

Hmm...longitudinal? How long is the crank? Just rotate 90 degrees and slap it in front of a Porsche 915 transaxle, call it a day.

It's not a problem, the Wankel rotary engine is DESIGNED to burn oil. If I were you, I'd consider using an earlier version of the 13B, the ones that aren't twin turbo. The twin turbo motors are a bit fikle, and once you start tuning for power, a single turbo swap is essential.

The first thing I thought when I looked into a Fiero engine bay was "hmm.... That V6 looks to be about the same size as a 13B..." and a creepy evil smile slowly made it's way across my face...

did anyone price any of this out? I priced out a 93 13b twin turbo with auto and a/c for 1300. the harness for 600 and computer i think was between 1000 and 5000, but i could be wrong.

You can get blown coolant seal motors (easy rebuild) or motors with blown turbo's for much less... In about 3 seconds I've found a motor with blown turbos, rebuilt tranny, and Apexi Power FC (which is the God of all standalone's for Rotary motors) and Commander for about $2500. But seriously, if you're thinking about implanting a Rotary engine you can build, I'd strongly consider getting an 89-92 model of engine. It has stronger internals, and MUCH much cheaper... plus no cheapy turbo's to go wonky on you...

sounds like it would be a pain in the ass to do not to mention that from what iv read up the motors are only good to about 70k and the motors turn to crap but hell if you can get it to work it would deffenetley be a big first keep me posted on it.

good luck

do they come with turbos. if not, would the motor be able to handle the turbos? I liked the idea of the engines having turbos.

Bull. The only problem with the Rotary motor is the owner (and the turbos on the twin turbo engines... ). Rotories are a bit more fickle yes but easily maintainable. The problem with this is that most people don't realize that you need to pay a tiny bit more attention to the actual engine. I've seen rotaries turn over 250,000 miles. The problem you most commonly come across is a blown coolant seal, which requires a full tear-down to replace, so most people will opt to rebuild with all new seals, bearings, maybe a little port job, apex seals, some measuring and shaving, and VIOLA! New motor.

true the only reason i dont trust them is they seem like a very touchy and tempermental motor and parts are expensive but it would be one hell of a swap if someone could pull it off.
