the motor depends on who you get it from, the stock motor itself is decently strong, people are running mid 10's on stock bottom ends.

do you need like everything underhood?

if you just need the engine/tranny/ecu/etc pricing will vary depending on who you get it from but your looking at 800 give or take. so having 2500 or so left over you should be able to put it into low-mid 12's
