Bov flange sizing

[James_dsm]

Im going to order a NGR Type S bov, but I have stock upper intercooler piping. Do I need a specific flange for it? It can’t be welded on for obvious reasons. Any recommendations?

Yes, it uses a Greddy flange, you can get an adapter for a skyline that will work the 1g BOV flange ( they use the same BOV as a 1g), I'm using this as my Greddy leaked, and wanted to go back to the stock, it works great.

You need an adapter like one of these JMF 2G/EVO BOV Adapter – Greddy
