The ZZ4 engine is mounted transverse and mated to the Getrag 5 speed using a V8 Archie conversion kit. Kennedy Engineered Products also makes a kit for other types of conversions but I didn't
get a chance to research them. I decided not to go with the longitude mount approach because I thought it
would be easier. Talk about tight clearance. There is about 1/8" of an inch between before contact
with the chassis sidewalls. Looking back, I wish I would have went with the longitude setup.
I'm not excited about have one V-belt running the power steering, alternator and air
conditioner. With a longitude setup, the serpentine belt could have been
used. However, I'm guessing the exhaust system would require more work to
I ended up getting a front-wheel drive Getrag from a mid-80s GM. It required the conversion kit from
Rodney Dickman. Since I had to extend the Fiero chassis 11", I had to get extended
throttle and clutch cables from West Coast Fiero. I ended up fabricating my own mounting brackets for the engine and
transmission. I wanted to be sure everything will hold up under the 405 ft. lbs. of torque created by the
ZZ4. I had a transmission shop inspect the transmission, put in new seals and a new speedometer
gear. Archie said these trany's are good for 500+ hp. I hope so!
