I got the 294 grind, which is an overall preformance grind. The other grind they do (the 101) is more for non-stock internals, lower compression, ect., not really what is best for my situation.

the plan

First I need to dyno the GT for the control. Then install, re-shim the valves, new valve seals since we're in there, and then dyno again with some tuning. Then compare the results.

From what I understand (on a 5th gen 5s) this should fatten my power band pretty nice. The mr2 guys get about +20 hp to the wheels with these. Now if I can get at least that with these, it should make a big difference when I turbo...

comments are welcome.

it looks like more lift, look at the base circle on the web cam, it's smaller/narrower

lift is going to be the difference between the distance on both sides of the cam... so if you grind the base circle down, you need to use larger shims, and that will make the lift higher without having to extend the cam lobe's other side that much ...

Yeah I wanted to say moly lube/assembly lube when you put those in, but alltracman beat me to it...

enjoy the cams !!!

good luck, and with a turbo it will make a difference. if it does make 20hp N/A then that means that say at 12psi when boosted you will be making the same power as someone running 15psi on an uncammed 5sfe with the same turbo.

oh also, if you have some money, this is a good time to buy a 2jzge cam gear (only need 1) and get it machined to fit the end of the stock 5sfe cam...

this way you can install it with the cams at the same time...and when you go to redyno you can optimize your power band (i'm guessing optimum will be around 3-5* of retard) that is if the web cam is timed exactly where the stock cam is...
