your all idiots, no offence, but the rb20 made more power on the same boost as the rb30 while being a litre smaller because of its more efficent head design and more flow. now if you increase the capacity of the rb20 it will create more exhaust pressure earlier and intern spool up the turbo earlier and make as much power (if not more) lower in the rev range, perfect for drifting. for outright power i would use the 26 head.

this particular rb20 comes on boost at 5000rpm and makes power untill 6000rpm, not good for drift, the 6000rpm sign off is not head flow related, rather cam related so the 26 cams should help there. an engine that signs off early is not as bad as an engine that comes on late. in drift racing, response is everything. hence the 30 bottom end.
