My intention is to mod the exhaust, remove cats, some type of cia and jump the boost up to safe level. I intend on also torquing the head bolts up to what, 72lb/ft?

It is an auto so bum deal on that. I understand that MKIII Supras are kinda gutless until about 60mph (stock). I have not driven it yet so I don't know for myself. I have read around the site and searched for alot of this stuff, but some direct discussion always helps.

I will have to drive it through a Wisconsin winter. Any tips on that?

I would yell at you to search, but that has already been established.

Supras.nl and goto maintenance for a head bolt retorque proceedure.

As for snow there was a thread only a few days ago with some tips http://www.supraforums.com/forum/showthread.php?s=&threadid=147608&highlight=snow+tires

And the mkiii gutless until 60 mph? Our engine has tons of low end torque, have you driven a mkiii?
