Any way you go will be $$$.
I've done a top end, ssi, m&k, ac delete, backdated heat, cobra rs seats, rotas, duck tail, rear seats gone, rennshift shifter, bilstein sports all around, lowered it, wevo motor mounts AND inplan on RS carpet and door panels as well as removing the floor coating.
I probably could have bought a 3.6 for the money I've spent already but then what would I have to look forward to
