New to the forums but been using it for years for inspiration.
I have a question on which Blow off valve would work for my set up. Currently have 2003 Z with a APS TT kit installed. since the blow off valve that was included with the kit is a recirculating blow off would it be possible to use a Tial 50mm BV which i believe is a vent to atmosphere. What would i have to do to change to an aftermarket BV is my main question. thanks in advance for any info.

 

The stock APS BOV is partially recirc, they had to do that to pass emissions in Australia where the kit is manufactured, you can remove the recirc hose and cap the nipple on the turbo inlet if you want it louder. Or you can get an adapater to make an HKS work (what i did) but for a tial, it will work fine but will have to drill a larger hole in the inlet pipe and have it welded on since the base of a Tial is larger.
My old setup, until my HKS started failing now im back to the stock APS

 

i see so i just have to cap the nipple? thanks for the help no i can start the process. will post pics when its finished and maybe a sound clip.
