I have run the same FC turbo since 2006.

This year I ran a Miata. Lol. I still have not torn into the FC to find out what happened, but it ran great in the past.

The only changed I have made that affected my experiences were this-

-one year with cheap duals catback
-next year with an Apexi N1 EVO
Wow what a difference. The spool up was much faster, which is key when you stay in the same gear almost the whole time.

-2 years with staggered 17" wheel/tire combo. 235's up front, 255's in back
-1 year with BBS vert wheels, 225/50's all around
Holy SHIT! The difference in handling was insane. With the staggered fit, the car wanted to push, and having no PS, she would fight me the whole time. After every run I would seriously have Popeye forearms. Having a matching width front to back made the car much more neutral and controlled. Stuck like glue!!

Hop this helps!
