Swap the motor with a 3SGTE (same engine in turbo MR2) you will need custom mounts and a transmission and from a 5SFE and probably have to have custom axles or trim the original axles. It may work. The setup will cost you about 4-5k but after you put another 2k into the motor you will have around 245-250@wheels which will be good for 100-120mph 1/4s. Good luck. Until then you can try nitrous and basic bolt ons.
