Whats your definiition of FIT??? As far as what engines have been put in well alot hehe, going from CA18, FJ20, SR20, RB20, RB25, RB26, VG30E and DE, some domestic engines, the supra I-6 (never bothered to learn the name of that one), and Im sure some other odd mix, oh and the KA24E and DE of course.
The frame mounts up to the CA SR and KA bsically drop in as all where offered in that frame in the s13's and SR and KA in the s14's (but the CA also fits of course). Those are the most likely candidates as they are the easiest.
So like I said all of these have been done but it depends on how deep your pockets flow, how much time you have, how well you can swing a sledge, and if their is a blood bank nearby
