RA gears are normally between $1350 and $1650 depending on availability and whether they are cryo treated. The shop we use charges $350 to set assemble them. Tranny in and out is $480 at our shop...

If you have RA's now, you are unlikely to break them again.

The header won't change much, but I wouldn't go FMIC without tuning...

While FPR's can be big helps on other brands, FPR's are VERY uncommon on Suby's. Many times they make it MUCH worse. The stock FPR is already boost-referenced....
