TII, what can I get rid of??
 

I recently bought a 87TII, and I also own a 95 3000gt Twin turbo, I was wondering what I can remove Emmisions and vacume line wise that I wont need. Where I live we do not need all of that. Has anyone else done any of this and seen any gains.. Thanks

If emissions aren't an issue (lucky sob...) opening up your exhaust would be the place to start.
A full race only exhaust system from mazdatrix or someplace similar would be optimal albeit expensive and quite loud.

Try searching a little as far as vacuum lines go, I'm not sure about that, and don't know if it would yield any performance gain anyway??

Ooooh, nice link Ocelot. I'll have to get some beer and read through that thing..

BTW - If your removing lots of emissions stuff on the turbo setup, you'll need an FCD.

Remove the air pump, & get a dual Alt. pully, remove stock intake...Stock manifolds & cats are way too heavy! :)
Good luck/skill!

Wow
 

Wow great information, I am ready for spring already. I have done all this stuff to my race prepped 3000gt too! Just making sure it wont hurt my TII..
