i just took the cover off the top of my timing and everything matches up all the teeth are perfectly sync with the stockers. So it's a perfect fit. Just so you (or whom ever is wanting this information) as little was said about it (actually nothing) previously on this site.

Still, just surprised AEM took their sweet arse time with their response.

I'm doing a timing belt on my friends 1g tomorrow.
It has these AEM adjustable timing gears.
I've done a few timing belts before no issue, but I'm looking for pointers on setting these things.I'm a little stressed about lining them up...
Bringing this from the dead

There is nothing to it, if your just doing a belt change. If however your looking to Adjust the gears then that's something a tuner will do on a dyno.

Or you can degree them cams to spec

Thanks for replies guys.
But I'm working on a 4g63 and posted this in the wrong section!
Here is a link to the thread I started in the correct section.
