There are various times...
Joe Type S did a 12.6 in his k20a 2000 integra Dc2.
1fstep3 did a 12. something in a k20a2 EP3
PACMAN did a 11 something in a CRX k20a
Norris did a 10 second pass in a insight k20a drag car (1600 lbs with driver)
Basically, in a gutted EG, high 12s-low 13s are very doable with no mods at all.

Well here you go this is my EG with a JDM K20A using Factory DC2R driveshafts with K20A inner CV's and a LINK PLUS engine Management..
So far it has run 12.43 @ 110mph and has a fastest trap speed of 112mph.
The car was still running the full factory body work, with a stripped interior, 8 point cage, and lexan windows. It has since had a new Diff, custom rear axle conversion etc done but no pics are available at the moment of that as we are still waiting on a couple of parts before its completed
