Hmmm.. spend $3000 on i/h/e, cams and a big bottle of cheater juice to have it blow the fuck up in a few thousand miles, or have a like stock GSR motor installed for the same price plus maybe a few hundred......???? that's not even something i'd think about... $3500 and i'll install a GSR motor in your car and it'll look stock and be as fast or faster than a 200 hp, non reliable, juiced d series...... take your pick, but do a little research before that money burns a hole in your pocket...
