Stock to Stock though, compared a k20R motor to a F series, its got us beat.josh green said:i would rather have the k series in there though, that car is butchered to have that motor in there. It looks like 1/2 the firewall is gone just for a header. s2000 ecu's are shitty, they limit the cars power. Not to many companies have put the R&D into them. You dont see hondata wasting there time with the s2k do you?
