i don't know if this qualifies as nissan tech
but it seems out of the turbo car crowd, nissans are populated by more idiots.
so here's some sound simple advice for people who don't know how to properly setup intercooler piping (IE: WELD ALL OF IT, minimal couplers)
if you must run 38 couplers, take the end of the pipe and a pair of needle nose pliers, and bend up three little prongs on the pipe. put on the coupler, then put the hose clamp behind the prongs.
you will never have a problem with having 38 couplers, except me.
