Link Found

we can use this post for interesting thingemabobs that we found on the Net
(not necessarily porn, you hear)

another restrictrictor that i didn't know about:
http://www.nissansilvia.com/forums/Free-Boost-Upgrade-t12212.html (haven't checked it yet)

I did that one my S14 (way back when)

and can't say it did much... Also - you absolutely have to have a boost gauge if you gonna try that

BTW, the mod is for S14's only, maybe the factory SR20DET S13's, but not off our local S13's
