Re:is it worth getting prelude type s engine?
 

Are you kidding? My buddy did a 12.9 at 110 on an LS with 13 psi. I did 12.9 at 113mph with 10 psi on a GSR, my other buddy did a 12.9 on a gsr with 10 psi. My other friend did 12.6 on his GSR with 12psi(head work and a quaife). These were all stock blocks and street tires.

20 psi with proper traction and proper tuning is an 11 second run easy. If you run any slower there is something wrong.

if i really hit 11 sec. then i think it really worth all the money and time i put in to it. i plan to take my accord to the track next month, to see how i'm gonna do in a quarter miles. i will be running 10 psi on my stock block.
