I installed a mild cam setup from Wade. I cant remember the specs onthe cam, but they didnt require adjustable cam gears or larger springs/retainers.
My ae92 Gti was excellent before i installed the Cams.
Afterwards, i obviously had a lumpier idle sounding much like a ported Rotory. I eventually had to increase idle rpm to 1K7 rpm to prevent it from stalling.
Anywhere below 5K and the car whent nowhere. 5-7,500 rpm and the car was at its best.
I did not have my ecu piggybacked with an interceptor to tune for the new cams, and also the 4age ran with a map sensor, and lost alot of vacuum during idle due to the larger overlap and duration. But it was bearable, and the inductin noise changed and was awesome.
Although performance wise i was still dissapointed.
New billet cams cost me about $600.
You defintately need an interceptor or an new ECU to take advantage of the new cams.
