do no't do that.
yes it's good to verify you have a car ready to handle the FI, but only replace the chains and rails IF you need to. they last well over 200K on the AFP motor, and the rails (if needed) can be replaced, but they only go around 100K + miles on neglected engines)
transmission - yes the 5 spd is much weaker than the 6 spd, but if not abused it can take the additional load (I know from 4 years of FI testing and running OVER 350whp on my car as a daily driver).
LSD - if you are wanting to run more than 250whp, then an LSD really is a must.
Clutch - the stock VR6 clutch is good to about 300 ft/lbs wtq. I used a stock clutch with 40K miles on it for 2 years running about 275whp and 270wtq...ZERO issues.
bottom end - the VR 6 is VERY stout and the bottom end in known to handle 400whp in stock guise. anything more than that, and you will need to upgrade.
Do yourself a favor. spend time in the FI fourms, meeting/talking with locall VR FI'd guys, and SEARCHall through these forums for REAL and FACTUAL info on a FI'd VR6.
there are many of us out here.
