I don't know but when I go to the race track, all the motors in the ek's, and eg's are mostly B18c1 or B16. And almost all the integras are GSR's or Type R's. I see quite a bit of LS's here but never at the rack track I go.

 

I have an LS motor and frequent the track as often as possible .

 

most the time i see nothing, but garbage at the track!

 

i second that a bunch of sohc civics, sunfires, and trans-camaro birds ! i am one of the only integra owners in my city!
