modifications on a 96 prizm to prepare for an engine swap - Toyota Nation Forum : Toyota Car and Truck Forums

Ive read in this site www.20v4age.com that the front engine support has to be modified to facilitate the engine swap. What other modifications have to be done in order to swap the 4age 20v into a 93-97 corolla(geo prizm)? Ive downloaded some wiring diagrams of the 4age 20 v but I dont understand them can you guys recommend some books or articles to help me understand what needs to be done with the wiring? Is the 4age 20v as reliable as the 7afe?

since you're not in the states... it depends on what motor and transmission you currently have..... along with that, there will be quite a bit of wiring that you'll need to figure out......

I have the 4afe with the 5 spd manual. I looked at pictures of the engine and I think the compressor is towards the firewall instead of the front of the car. Do you think this will be a problem putting together the airconditioning? what about that engine support? Is the ae92 engine bay the same as the ae101's?

If you started with a 4A-FE, then chances are you won't have to do anything too major with the mounts. Maybe switch the mount by the timing belt with the 4A-FE one if you don't have both parts of the 20V mount.

how about those wiring diagrams. can you recommend any referrence so I can learn how to interpret them? do I need to get a new wiring harness if I do the swap or will the 4afe harness do?
