For Non-VVT-I peoples, i think i found something that may work :) will it work? idk

here's how it goes:

Crower Stage X set from MWR
New Exhaust Cam pulley
New Timing Chain
from toyota
New Intake cam pulley for 98-99

I think this should work. i dont have the assets to try it though. opinions ?

i though of doing this for a while, and sticking with the non vvti head, but then i saw the differences in the cams. my biggest worry is the vvti cams have oil supply holes drilled in them for the vvti actuator. i was worried that a vvt cam in a non vvti head may lose oil pressure through these holes.

the second problem would be the flying magnets on the end of the intake cam. they produce a signal for the ecu to fire the coil packs. the non vvti has 2 flying magnets the vvti has 4. i think they could be machined off just fine and it would work. as for timing it looks close.

new timing chain sounds good, but i would just swap the old cam gears from the cams. no need to buy a new gear if it is not damaged. other than the concerns i have listed i see no reason why this could not work. the extra oil holes could be plugged. i would be interested to see how the non vvti takes to larger cams.

i'll call MWR in the morning (maybe you should as well) give them the rundown and see what they think. this could be a nice breakthrough for some of the 1zz community should everything work.

thats not too bad. did you ask if they are reginds, hardwelds or new billets? any limit to what spec cams they can do?
Hardweld. The lady didn't specify a limit as far as cam profiles. She did say the stocks have to be mic'd for stock profile and lift and we could go from there. Damn I wish I had a spare set and some cash.
