Great thread!
I'll be weighing up the same options in the months to come, tossing up between a HKS2530 or high-flowing, at the moment i'm leaning towards the hi-flow due to no post purchase fiddling.
Sydneykid, how far can you actually safely push a high-flowed RB25 without having to look at fuel pumps and new internals?(220rwkW?) Cause I dont want to take it past that point really. All i'm really after is more power in the low and mid range with the responsiveness of the stocky, I'm not after wopping topend speed.
Do they design the high-flow to the way you want, as I mentioned above?
