My wife totaled her 1994 Chevy Cavalier 2.2L 4cyl. It has a 5spd in it. Is there any possiblity of it bolting up to my '84 Fiero 2.5L 4spd? I don't know if 2.2s and 2.5s have the same bell-bolt pattern. I figured since the Fiero's rear end is a FWD cradle turned around, it might work if they used the same tranny (granted I'd need shifter parts form a 5spd model to finish the conversion). Thanks for any insight.

From what many have explained all fwd 5 speeds are getrags and the only that won't work is the quad 4 five speed. You will need a kit that rodney dickman sells. Some of these getrags may have a different gear ratio, but all except the quad 4 bolt up.

No...a huge number of FWD transmissions were Isuzus, and this Cavalier trans is as well.

------------------ My Web page | The Turbo Super Duty Build. You know that little voice that says it can't be done? I duct-taped mine's mouth shut and pushed it down a flight of stairs.
I figured it was the Isuzu box, but is it the same box used behind post '84 2.5 Fieros?
The '84 Fiero has a Muncie 4 speed. A 2.2L will not bolt to it.
From what I have been able to determine there are three different bellhousing configurations for the 5 speed Izuzu. The actual gear box appears to be the same among these three versions.
1) 85-88 Fiero 2.5 2) 2.3L & 2.4L Quad 4/Twin Cam for mid to late 90's FWD cars 3) 2.2L pushrod and 2.2L Ecotec (the cavalier drivetrain)
The shift mechanism may be tranferable from the Fiero version to a FWD version. So there is the possibility of swapping a 2.2L engine and 5 speed Izuzu from a Cavalier into a Fiero and then using the Fiero drive axles and Fiero shift mechanism. I'm looking at doing a similar swap to put a 2.3L and it Izuzu into an 88 Fiero 2.5L/5speed.
the ecotec is a different drivetrain - but the older cavaliers used the same bolt pattern as all FWD gm's - I had a cavalier isuzu bolted to my last GT - I know they can be used but NOT the ecotec.. I thought the ecotec used a getrag anyways

Not true. The 2.2/2200 OHV does NOT have the same bolt pattern as the Ecotec. The 2.2/2200 OHV have the same bolt pattern as the Fiero engines. They will bolt up to any Fiero transmission including the Muncie 4-speed. The Cavalier's Isuzu 5-speed can be used to replace any Fiero transmission; you would need to use the Fiero Isuzu mounts and brackets though. Also keep in mind some of these may have hydraulic throwout bearings instead of a slave/lever setup.

My bad and apologies to all for the mis-information
What I do know is that the Twin Cam Izuzu and the Fiero Izuzu have the same gearbox dimension and therefore can use the same drive axles. And it looks like the shift mechanism can be switched from a Fiero Izuzu to a Twin Cam Izuzu to be able to use Fiero Izuzu shift cables
I have heard but have not verified that an Ecotec engine and transmission can be substitiued for the engine and transmission in a late 90's Cavalier. This would mean that the drive axles interchange and the shift cables work with it.
If this is the case then it would seem like an Ecotec engine and transmission could go into a Izuzu Fiero without much work.
