the kit is only 3300, but don't forget engine management. I paid $3900 for my RevHard back in 2001 and ran since then with shitty tuning (FMU or VAFC) and was miserable (except at the dragstrip.. )

I made 295whp at 8500 on a mustang dyno once I was Hondata tuned at about 10-11 Psig.

Erik on this board made 306whp (not sure what kind of dyno) at I believe 10Psig Hondata tuned...

What do we have in common...?

tuning.

And both of our cars are alive and well, so you can expect this type of numbers if you have common sense and don't kill the motor with too much boost, too much timing advance, or not enough (or too much) fuel..
