February 18, 201511 yr comment_694289 Hi All, I have an AE82 twinkly that someone has put an e58 gearbox in. My mechanics won't pass it for a roadworthy cause he thinks the mounts look wrong. Has anyone managed to do this swap without backyard hacking? I don't want to have to get an engineers cert. Report
February 18, 201511 yr comment_694292 Don't know about an 82, but on a 92 it's all 'stock' mounts that hold it in. E58 isn't a great swap unless you're looking for strength anyway. Heavy and final drive ratio is taller than standard. Report
February 18, 201511 yr Author comment_694297 Thanks, Hmm, well is seems to be far from stock stuff here. It has an LSD which is nice, but for a daily I might be better off to swap it back to standard then. At least my mechanic will pass it then. Looks like a fun weekend ahead for me... Madmorrie Report
March 11, 201511 yr Author comment_695022 Well, I think I have it sorted with a single 25mm spacer at the rear of the crossmember, and I've reverted to an AE82 top gearbox mount which just required a plate to pick up the other gearbox mounting hole. Will remake the spacer out of solid alloy (its wood at the moment) and hopefully my mechanic will pass it. If not I might shop around for a RWC. Does anyone know if there is any way to tell a 4AGE from a 4AGZE from the outside? Report
March 11, 201511 yr comment_695024 Does anyone know if there is any way to tell a 4AGE from a 4AGZE from the outside? Lots of ways if the motor's complete: lack of supercharger/IC, distributor/leads instead of CAS/coilpacks, intake manifold... If it's just the block & cylinder head, the 4A-GZE cam cover has 'supercharged' on it. But since they can be swapped over, it's no guarantee. Report
March 11, 201511 yr Author comment_695033 It has no supercharger or anything, just looks like a regular 4age in any AE82. I'm wondering why someone has put in the big gearbox thats all. I have had the head off, but did not suspect anything at that point so didn't worry too much. Do the GZEs have low comp pistons or do they look the same? Report
March 12, 201511 yr comment_695050 Do the GZEs have low comp pistons or do they look the same? Low-comp pistons but everything else is the same as the equivalent year 4AGE Report
March 13, 201511 yr comment_695064 4AGE pistons - left = 9.4 to 1, right = 10 to 1 4AGZE pistons - left = 8.0 to 1, right = 8.9 to 1 Report
March 14, 201511 yr Author comment_695073 Cool, thanks guys. Presumably not a GZE as my pistons look like the first image. I won't go strapping a turbo to the side just yet then;) Report
