Web Cams 294 regrind, Need help with this. Options

[bdawgbp1]

I just got 2 used cams from a 5S and am going to send them to Web Cams to get the 294 regrind done. I am running a basic modified 5S-FE in my 94 GT (CAI with K&N, 4-1 race header, Nology Hotwires, Pulstar plugs, and am fixing to have full header-back exhaust done next week - 2.5" or maybe even 3" for future boost). I was wandering what do I need to do with my stock head for the 294 regrind? I have been reading in the forums and have seen stuff about the valve shims, clearance, etc. I originally had intentions to buy a new/rebuilt head but didn't know if there would still be some additional work that would need to be done to it for the 294 setup. Any help would be greatly appreciated as this is my first "tuner" that I have done - pretty much done this sort of thing with '70 to '80 something model V8s before but the Toyota is another whole different ballgame. Thanks!

Hey cool thanks. I also just bought an HKS adjustable timing gear for the 2JZGE (I read in one of the forums that you can use this gear to adjust cams for optimum performance - I think it said somewhere between 3 - 5* retard). Can Web Cams machine this to fit the 5S cam or will I need to take it to a shop to have that done? So I'm good to use the stock valves, lifters, seals,springs, seats, etc - the motor has 203,000 miles on it and you can hear that "Toyota" valve clicking going on now. I didn't know if I should tear apart the head and rebuild or just buy a rebuilt head altogether. Also do I just use factory timing belt - any recommendations? Should I change the oil pump or anything else while i'm in there? I'm guessing that the stock timing belt pulley/gear on the crank will be fine. Thanks for the info.

i dont think webcams will do that machine work for you, but any decent shop should be able to modify the 2jz gear, although with the slave cam design of the 5s, there isnt as much to be gained as with a true DOHC design.

yes, you use the OEM timing belt (yes, get a new one, theyre under 40$ new.) and do the waterpump, tensioner, and idler pullies while its all apart)
