Default Updating an old begi kit.

Hi all. I have a 91, turbocharged approx 15 years ago with one of the original begi ihi unit, complete with afpr, j&s knock sensor and a recirculating bov. It is such a beautiful car in every sense that I decided to spend some good money and start updating her.

Already swapped the rear to a full torsen updated the clutch, and dropped the six speed in. I just installed a Mspnp and Lc-1, which I will be tunning soon enough. My question pertains to what need to do with the old fuel setup.

-i removed the vacum line from the afpr, enough or should I go ahead and remove it?

- can I continue to use the j&s or should I attempt to remove it? The Mspnp is apparently only wired to deal with msknocksense, however if I just unplug the j&s, car wouldn't start.

- should I remove the recirculating bov or just leave it there?

the car already has a pierburgh and am looking to drop some 460's in.

Can you guys think of anything else I should do?

Thank you, Fadi.

remove afpr and put in the 460s (sell and recoupe some cost)
use the knock sensor until you get msknocksense
keep BOV or upgrade it
remove MAF

If the thing hasnt been modded in 15 years, your exhaust is still probably 2.25". "Updating" it to a full 3" will make a noticeable difference.

det cans > knocksense for tuning...but KS is great for safety after the tune.
