It's plenty for me with a stock engine and S13 as a daily, but I do wonder how a GTX2867 with a larger AR hotside would have done. Probably pretty wild with some cams, but I'm not sure a stock SR20 would handle that. 2867 is also +$500 vs. the 2863.

good info to know, yea i have an entalpy tune, refreshed SR, stock pistons but new rings,bearings, head has been fully rebuilt new everything, tomei poncams, 750cc injectors,fpr,etc.
I called ATP they said the 2863 is newer tech compared to the 71 or 67. does the 64 feel restricted ? Granted i want more lower/mid range anyway so i think a .64 should be fine.
