yeah i know tons about them motors i have one in my mx3 ....preformance wise u can.....

turbo it yourself b/c they dont make a bolt on kit for the v6 but its on that hard to do if u get the turbo mani and downpipe which they do sell for 500. the blocks are good for 600hp... the stock rod pistion combo well i wouldnt put more than 10psi with a walbro 255l fuel pump and millenium S injectors that set up is good for around 260 280hp wire it tuned right.
pacesetter makes headers for around 200.
ACT stage 2 clutch is probly the best clutch for that tranny and runs around 315
EXAUST>Really the best bang for your buck is remove the cat. and resintor and run 2.5in all the way out that motor is so air restricted with the stock exaust.
Millenium (kl03) or klze intake mani. will bolt right up to your motor and with a mild port and polish you will be admazed how much tourqe it brings you,
well im sure theres lot more but i cant think of anything else , is u have any more Q's PM me thanx!
