No idea but you do know what JASMA is? Well originally before they named parts after them.

Just don't get those cams. Enough said

[ke_70]

why? whats wrong with them?

a cam is a cam. sure toda billets are alittle lighters and stronger for very slight power increase.

WHOA!! NOT all cams are created equal, it's just not a matter of grinding up a duration and lift!! There is much involved in making sure the valve train doesn't get unwanted harmonics, that the valves aren't pounded down onto the seats, that the valve and valve train is accelerated and deccelerated with regards to longevity, do a little research and you'll be suprised at the amount of mathematics that go into designing a camshaft these days, in the old days it may of been experience and suck it and see but not these days.

Save headaches and coin, by waiting for someone to ditch their project (part out) and get some Toda's or HKS.

I purchased Jasma branded vernier gears for my 20V and was disappointed with the quality. I returned them for a refund and would be skeptical of purchasing the brand again.

I suggest clive cams here in Vic, known to work and can offer something that works with a stock ecu or tuned.

as usual Frak is right, agressiveness of the ramp rates and duration above 3/4 lift are some of the things that go into the design of something that's deceptively complex.
