I have an 1989 toyota mr2 s/c i wana put a larger motor in it...more power stock that is ...what options do i have or what can i user to swap it out with? any help would b nice ..thanx  

Twin charge that [censored].  If you have the money.  If you don't, borrow some from Ro.  

Seriously though, the amount of money you're going to spend would surpass the value of a newer SW20, so I wouldn't recommend it.  Just pick up a Nitrous Express (dry, single fogger) kit and call it a year.  

well i most deff have enough bank for whatever ...but the supercharger i got on it now came stock with the car...gives me torque and off the line speed but i want more top end ... like 3rd 4th and 5th gears thean anything i dont really care about 1st and 2nd there fine as is ..could i get a motor from a supra or maby a celica gts or sumthing ???i most deff wana do a motor swap though...iv got 10k to mess around with ...
