i remember that 3rz 180sx of richards... tough car... i beat it at powercruise dyno comp a few years ago:) allbeit by default but a wins a win!!
i reccomend Paramount Performance in toowoomba... truly worth the drive
they have tuned several of my sr's one making 550rwhp and one making 320ish and others ranging from 240rwhp-300rwhp... never hurt an engine yet!!!
