So I just got back from a trip out to meet the great Milky and we installed a mod I feel should definitely be getting more attention than it is. It took us about half an hour to do and it provided a very noticeable gain to the butt dyno. We took the intake cam from a 98 99 Non-vvti Corolla and installed it as my Exhaust cam. You go from 224 degrees of duration to 240 degrees and you gain 1.1 mm of lift. I literally had 25 dollars into this mod and it is extremely noticeable with the celica gt ecu in the higher rpms. There is a couple of modifications needed to make the cam fit. The end needs to be grinded off and there is a stud on the valve cover oil baffle that also needs to be ground down.
