thats funny.. his SR is stronger than ur RB20 its closer to being a GTR than a GTST really.. Solid lifters. 87mm pistons bigger oil pump similar to a N1.. the GTiR engine was the GTR or SR..
and a set of RAS will fix that.. i fitted some yesterday on a VCT SR.. stupid having to angle grind the rocker cover to miss the VCT gear oil shield.
