The T465E trans has some ridiculously low service interval. I want to say it's around 90k, maybe someone can help me out there.

I've been reading most guys use a bottle of lucas after the procedure. Here's a link to the default guide on the forums ~ http://www.grandprixforums.net/threa...ailed-Pictures

It uses an M112

The M112 has been fitted to this engine. Go over to the members rides and there's at least one whipple-equipped example too. I've read there's a larger kit that fits an M122 to the 3800, but I don't even know if that guy is still around or many he came up with. I did a bit of research about superchargers recently.
