i had my RB25 bottom end rebuild there a couple years back now...
took them 14 weeks to do it and f*kd me around for a while, but they did a pretty good job in the end. i didnt hav a single problem with the car from the time i got it back till i sold it 14 months later.
so to cut a long story short... they're good but u hav to light a fire under their ass to get them moving
but wat do u expect from maso's
