bro you want to tell me what is the diffirence between BT and ST?
and yes its an easy swap. all you need to do is probably throw the battery in trunk.. new mounts brackets,,,, etc.
i assume you get easy 15 to 20hp plus boost by just having less weight to carry around than corolla, so it means even yr car shows less hp on dyno, it will smoke off easy bigger cars. go for 2.25 exhaust/ honeycomb intake bolted. and yes about mounts,, get at least 2c diesel 1's if you cant find TRD.
stiff the suspension, otherwise it will loose control at speed. tires no less than 195 low profile.
light weight alloys recommended not heavy type
