Skunk2 springs like to break. A local girl bought some for the Delta 272's in her Integra, broke two before she said ---- it and bought a VTEC head.

REV seems to be okay, they have a good name outside the Honduh scene. If BoostFed runs them you know they are good... he makes, what, 800 whp to run mid 10's? That's a lot of bouncing off the revlimiter and flailing around wildly with the gas pedal to go that slow, and if their product holds up to that I give them my vouch.
