Around 5k on just the engine and install. With engine upgrades I don't want to say anything :P cause knowing me I'll blow whatever I calculated right out of the water haha. @jeremydawg I doubt I'll get the H22 S. A bit pricey, I already found a H22A2 with 80k on the dial for $1350. The only reason I would get the H22 is because of the torque in the first place, but I am kind of doubting I really need so much torque in such a light car (1132kg roughly). Kinda leaning towards the B18C, also I'm worried about clearance issues. I don't wan to have to COMPLETELY butcher my car.
