hey guys i replaced all the plastic after the airbox on my qg16 and replaced it with a short piece of PVC 2" pipe and i think the car has gained or shaved of 1/2 - 1sec from 0-60 but i'll do an other run with all the plastic and get back with u guys with video. waiting to change my sparl plugs cuz those i got have been there for about a yr and a half already, looking to switch to denso IK16.

my car does 11.5sec from 0-60 or less now with no mods or anything when we got it it was about 12.5. haven't changed plugs in like 1 1/2yrs and its still pulling at that accel. do u think by adding the iridiums i might shave of a half sec. i need to do another test withou the whole plastic piping vibe and see what happens. internet at home is down so whne its up i'll post some vidz.

If it's anything like the Subaru engines from that era when Nissan had shares in Subaru still it could be to warm up the engine from a cold start. The valve is partially open for it to burn rich until it reaches operating temps it opens fully. Subaru is motorized and called tgv, Nissan could be vaccume controlled with a solenoid from the ECU. Do you see a solenoid on the line?
