hey... i've been watching this with a keen eye, but no-one's brought up this question: don't you think you're overinvesting into this car? if i were going to put a gze into an ae71, i wouldn't go much further than preventing the rust from getting really bad (or fixing it if it already is), getting a supra gearbox + adapter, an LSD, a little work on the suspension and brakes, an SC overdrive pulley, and yeah, getting it running. that'd surely be a cheap and highly enjoyable car i sure as hell wouldn't bother getting rid of ALL the rust, installing central locking, respraying it or any crap like that... but then, how long have you got til you can legally drive on the streets? like, how far off 18 are you?

i definitely want to keep it front engine rear drive. as for keeping it streetable, emissions wouldn't be a problem as we've kinda established... as for noise, well, being an old car it'd be allowed 96dB at 75% of peak rev's... a busa revs to 12,800rpm, so assuming that, it'd have to be below 96dB at about 9600rpm should be doable. what i'm worried about is the gearbox conundrum. might go talk to a gearbox guy about adapting an rx7 box to a busa motor. since they rev fairly high anyway, adapting the diff ratios to suit shouldn't be terribly difficult. anyway to summarise: -street car -front engine, rwd -stripped down as much as legally allowed to minimise dead weight if it can't be done relatively affordably, i'm more likely to go down the 20v 4age way. but i really, really don't wanna do that.

grimwolge: i was going to look at removing the standard transmission and getting a bell housing made up to accept a car rwd transmission. not sure whether i'd prefer (financially) to get the gear ratios changed, or just change the diff ratio and get a "tough" tranny to start with. demuire: the thought had crossed my mind, but i'm kinda thinking despite there being different sets, that an r1 or busa motor, particularly the EFI busa motor, would have better emissions than a corolla from 1973, regardless of it's 2 wheeled status. i haven't looked that far into it yet.

hi. probably a bit forthcoming as a first post, but i've got an opportunity to pick up a ke25 for cheap. i've had a couple of fastish cars, i'm into bikes at the moment but looking for a runaround. ke25 sounds good :D anyway. i'm a mechanical engineering student, looking for a whacky project as well as a runaround... now, i'm all for putting newer engines into classic cars, but i dunno, a 4AGE doesn't really appeal to me. sooo.. since they came with 1.3l engines (i think?), and they're RWD, i'm thinking an R1 or hayabusa motor conversion. R1's were carbied in the early days, which makes things a little simpler. in any case they'd produce a fair whack more power and torque than 3k or 4k. obviously i'd have some messing to do mating up a gearbox to it, but i could probably get away with some crazy-ass diff ratio and make it work (and be fun) but i'm just wondering, has anyone done it before? an r1 engine being a yamaha, sorta keeps it in the toyota family.. :doublebird:
