Lol... I'm glad I saw this thread - just done a lot of the research... I have an AE102R and it comes factory with a rear sway bar (safety measure) which is 17mm thick... the most popular upgrade to that is to go with a White Line rear sway bar - however this is not necessary unless your using the car on a track (which is highly unlikely because its an AE112) as the White Line rear sway bar is only 19mm, which is a big outlay for something your not going to use the full range of on the street - so don't do it... I also had the idea of shoehorning a 1MZ-FE into mine, but the amount of time, effort and money it really isn't worth it... firstly without pulling out the 7A-FE and trying to drop the 1MZ in its place to see what's going on, your not really going to get an accurate idea of whether logistically it will or won't work... there's a lot to consider, i.e. engine mount mounting points, chassis rail widths, will you need to cut back the rear firewall, will you need to flare the centre hump to accommodate the E153 gearbox (if you go manual) to accompany the motor, how hard and where and who are you going to pay to figure out and wire up your wiring harness... the list goes on my friend... It's a 7A-FE motor... your best bet if your going to go the road of transplanting an engine is to get a 4A-GZE (supercharged) or a 4A-GTE (turbo) or a N/A 4A-GE 20 valve (naturally aspirated)... it works, it fits, and it won't have to be certified if you get one from the same year model corolla as yours because it came from the same year range and model that you own... getting a mod plate and engineers certificate for a 1MZ would be a nightmare... whatever you do though, don't go just sticking a turbo on your 7A-FE tho... you will need to build some of the internals first as the conrods on this motor are like toothpicks, and you'll need dished and forged pistons to lower compression to safely boost it... The AE102R and the AE112R share the same chassis and many of the parts are interchangeable... to mine i've installed KYB Excel-G front shocks with Super Low King Springs at the front, Monroe shocks with Low King Springs at the rear, and that is pretty much it and the ride is very firm - verging on uncomfortable... it doesn't take much to stiffen these little cars up so don't go overboard - especially at the rear end or else u'll oversteer something fierce... the only other thing I would do to mine is a 2 point tower strut brace for the front end... Hope that helped :D
