im looking into fitting adjustable cam gears on my motor. My ge has slightly higher compression (guesstimated to be around 11:1), 1mm oversized pistons and ported head. I cant justify the cost and effort of fitting larger cams. in a daily that i need reliabilty its simply not practical as i would only do something after adressing the shim over bucket issue. its a PIA swapping and i most definately dont wanna spend the money on shimless. when (if) i fit adj. cam gears i will also be running a S-AFC. i already intended to spendd some time on the dyno tuning the safc. i know that in the gte's its quite beneficial advancing the intake, in some cases as much as 10 degrees and retarding the exhaust slightly even with stock. so i see no reason why this would not be applicable to the ge. The cam gears really arent very expensive and im more then capable of fitting them and as i said i want dyno time anyway so tuning isnt really the issue. so what are your thoughts? has anyone seen anyone do this and seen any results?
Pretty sure Mafix is running adjustable gears! I know there are some cheap ones. I was told they strip out and break! Buy good ones, I am going to get them too! I still don't know which, maybe AEM or HKS!
i wouldn't think youd need them unless you have cams. im the opposite i have cams but need some type of ecu to really justify cam gears. my cams were 200 for a proper weld and grind, and 150 to shim the head. -iirc non ebay cam gears are more than that and youd only net a couple ponies at best. stock cams should be properly timed anyways? cams would be a much better uprade for the $
the cam gears will work. you need a dyno to tune them proper. however i do NOT recommend the SAFC. the tuning capabilities for that unit conflict with the stock ECU and cause issues. i do how ever have a solution for you rev. which i can go over in a PM.
Heres what happened to mine. Baseline dyno was about 130hp. Fitted camgears and an EMS fully prog ecu and got to about 145whp and 155torques. This year fitted arias race pistons 1mm oversized (11:1). Retuned the ecu. Havent dynoed yet but a good conservative guess is at least another 10 hp. Quick solid response. Good idle. With another dyno session shud be able to get to 160 to 170whp or so without raising redline over 7500. Not bad at all. In my opinion the camgears did make a lot of difference in power and response but i think the ems computer was the needed tool to really get every last bit of power. Had a buddy club piggyback before which works like the safc and it just didnt quite do the job. Hope that helps. Need to mention though that this engine is in a lightweight ae101 corolla race car. So the power is just about right for fun track runs.
