read the dyno thread and do a search, anything bigger than stock will spool slower than standard.

not necessarily. if your exhaust wheel is the same or similar size as stock then theoretically it should spool at the same rate. add to that any improvements in bearings, lubrication etc over stock and it can possibly offset any increase in size.

I've got an HKS 2530 kit on my RB20 and it spools at around the same rate as stock.

Lol I really doubt that, they are on full boost at what 4000rpm+ ? A stock turbo is on by 2500rpm max.

Cyo18r - Please read the dyno sticky, and do a search.
