Customize your motor:

"This thing is an absolute mind bender it took all my preconceived notions and blew them up. This car makes 1500 hp and cruises down the road like it has a crate motor in it, then you lean into the throttle and following a brief spool up time (almost none at all when full boost is available) the car accelerates like there is a JATO rocket strapped to the roof. This is something you could drive seven days a week to cruises or down any major street in America. Its real, it works insanely well and I can't believe it either. I guess the best praise to really give is that it will remain a life highlight to say I piloted the thing.""
