MWR stage 1 cams 2zr-fe - Heads Up

[remcafee]

yeah i ran into the same issue with my jun “bolt on” cams ended up having to change lifter shims and spark plug gap because the valve clearance was screwed up and i would get random misfires on cold start. so much for bolt on performance. oh well i guess we always fall for their large print on advertising of their parts and we have no choice as nobody esle basically makes anything for our cars unlike hondas

Interesting, I have the MWR lightweight flywheel as well. When I installed a new starter I had to swap over the pinion from my OEM starter as the pinion on the aftermarket one wouldn't fully disengage and would cause a grinding noise.

I chalked it up to an aftermarket starter that was out of spec but it was from a recycler so I didn't know for sure. Now I'm wondering if it was actually the flywheel that was slightly out of spec. I also could have spaced it out a bit too, that would have solved the issue.

It definitely seems par for the course, aftermarket parts tend to need a lot of trouble shooting. I now leave my DD'ers fully stock. It isn't worth the headache of dealing with aftermarket, especially when I already have a track car for that purpose.

Lol, I'm anxiously waiting for Toyota to release a Battery Electric vehicle so I can get one as a daily driver! I'm too old to be tinkering with my commuter car. =)
