doh rb20 thread with a rb25 infiltrator... f**ked with my head.
T67 10cm or 12cm td06-25g still wont cut it 300rwkw ish maxed, if it is actually a sh-25g 330rwkw is ok.
Below is a R32 RB20 dyno graph. 1.2bar on std rb20 231 corrected rwkw (engine kw is the scale on the graph with more boost) pay no attention to the shape as their scales make it look laggy when actually its really not (the L2 and 06S are very much the same only the L2 is more effecient at higher boost up top.... less roll off). i have also attached a dyno graph of the TD06s-20g on a RB20 you can see it mirrors roys setup only as it runs less boost it only makes 248.8kw
another option is a HKS 2835 56t with 0.61 housing, this works extremely well and i have used these in SR and RB config. (james vahoumis bought my SR HKS 2835 kit and used it in his championship winning s14.5) both Bai and the other D1 drivers prefferred the L2 (like myself) over it though. i also spent alot of time in james cefiro with the HKS 2535 and it was killer street/hills drift but is just too small for serious track drift, 2530's just too damn small.
