im pretty sure k20 engines and gear boxs are slightly lighter than b-series
imo save and get a k series motor in ur car. in the long run it will be the better option. they respond to modification a lot better than the H and B series do.
if u are considering saving for a k-series then do some reading at k20a.org. should be enough info to convince u the wait and cash is worth it![]()
