Hey, got a hyper st pro and the mac star 28 engine that comes with it seems to always require some kind of working doing on it, and can never get it running right, has a habbit of developing air leaks in the car and that for fun, never get it to hold a tune for the time it takes to put the body work on....
does anyone recommend a better or atleast more reliable engine for the job, want something reliable. quick but without braking the bank. reliability it put slightly before power,, but power is helpful
