hi guys I'm 17 and have myself a ae82 rolla with a bigport 4age that i race at hillclimbs and sprints, i have been doin really well in it but i think its about time to do a bit of work to the motor. just want to know whats the best direction to head in, as in what to do to the motor first and wheres good places to source parts from. my aim is to get as much power out of the motor as i can. i only have about $1500- $2000 to play with tho.
