However, its like another or new car when ya add 150hp. Do some math. Sell yours, and buy a car, newer, with that much HP. See what ya come up with. I think great idea to build, your own. I usually do something, to my car once a yr. Add something, make something better. I have a wish list that keeps growing lol , just wantin little more i guess...Affordability speaks volumes, I get that. Some yrs just fixed stuff, and did cheaper mods. ... cheers
