if built right, ive seen many, many NA hondas run low 11s. in fact the guy who built my engine ran low 11s in his b-series NA crx. if you go to the track, you have hear of him. his name is Neal Sutton, prob one of the best NA builders around.

heres a mod list to back up what i got and why my car is quicker than your average NA honda

im sure im missing a few things here and there

everything down to the gaskets has been replaced and rebuilt by Neal Sutton. he has never built a motor that hasnt performed. do a little bit of searching on this site and youll see what i mean. car is currently running a basemap and needs a cleaner tune so it can be a little stronger.
