dude, just leave the rolla alone is what everyone's tring to say. then you can do the supra the right way and have all the best parts on it. then when and if you ever get the supra done you can then concentrate your efforts else where. i.e the rolla. or the other popra. i'd love to have tons of project cars, but i'd also like to have something nice and maybe good on gas to get me around daily. and bone stock the corolla fits the bill. corolla's are just plain fun to drive slow and bone stock. maybe you should concentrate on your driving more than needing more power. the key to the rolla is tring to drive faster than everyone with no power!!! and don't say i don't know, because i bet your rolla is faster than mine. mine has no compression at all. in order from piston 1 to 4: 70psi, 120psi, 120psi, 125psi. and i think stock should be closer to 190 to 200 i believe. and i still haul ass in corolla. even chin in his 360hp sr 240 can't keep up with me in traffic.
