i'm aiming for an sr20 redtop engine swap this upcomming summer and i've found some decent prices out there with tranny ecu wiring harness and everything so all seems good.

but enyone out there can give me a real read on the whp after the swap and what some times are in the 1/4 mile?


and is it worth the extra money for the sr20 blacktop? its not much more and it doesnt seem to say it puts out enymore horesepower and i dont really know what the difference is?

 

sr20 stock I've seen run mid 14's
sr s13 blacktops are newer, this is the reason there more expensive also, personally its not worth it.
