So other then pictures i'll just tell you what i all had to and have to do. First thing first is find a donor 2.8 V6 out of a fiero. After i did that i got the Fiero to my work place, and started disconnect everything and drop the cradle. Ran into a couple problems but everyone who drops a fiero cradle has some sort of problem. After dropping the cradle you then have to take the engine off the cradle, pretty simple have two cradle mounts and the bell housing bolts then its off. Then its time to prep the other motor, you have to take the top plenum off so you can get to the fuel rail to remove the fuel lines. Then because the donor V6 i picked up had an Automatic harness i had to completely strip that off, and replace it with a manual engine harness. Once the engine harness is on, i proceeded to put the V6 fuel lines on and a newer fuel rail. Then you can put the plenum back on. The 4 cylinder and 6 cylinder have different Flywheels so luckily i had a spare laying around. The clutch and pressure plate are the same tho. The transmission spline is relatively short so it makes it a hell of a lot easier to connect the engine.

List of differences between the two

-ECU
-Throttle cable
-coolant hoses
-Flywheel
-Fuel lines
-Fuel pump
-Engine harness
-Engine mounts
-Exhaust


Engine that came out



Donor Engine



Engine stripped down



Automatic Harness and V6 exhaust



Better Fuel rail and injectors



Easier to take off caliper then it is to bled them



Engine cradle being dropped out



Best way to jack up car, use cherry picker and lift on the trunk latch



Have to get the cherry picker out of the way some how lol



4cyl. off the cradle



V6 off the other cradle



Good bye Flex plate and hello Flywheel



V6 bolted to transmission and cradle



Fuel lines and plenum back on








It is now already to be put in, started to rain so I figured i would come inside and post this Build

Should be fun! You should clean that intake and those valve covers up though while it's out!!

Oh noes! It has an automatic!!!!! I wouldn't mind having a v-6 fiero sometime but it would have to be a stick. An auto in a mid engine car would be like an rx7 with an auto.

Very nice work and write up though!

I think he said he converted it from a 4 cyl/auto to a 6 cyl/5 speed

This would be correct unless its some high powered engine the fiero needs a 5 speed to even make it worth getting into. When you get to high hp really the only choice is the 4T60-E HD.

I just said that the neutral safety switch was disconnected so i didn't have to push in the clutch. Laughing
