The all new v3 housing and v2 Water Neck is here. This has now officially superseded the v1 and also included in our Turbo Kits. How did we improve from the v1. For starters we removed 3 most unused ports ( 2x 1/4 BSPT + M14 ). We redesigned he housing to look more simplified and add raised boss for enhanced design. The water neck was also redesigned with the removal of the bottom port. We then switched the remaining ports from NPT to 10ORB (O-Ring Boss/ AN). No More seal required! 16AN version is HERE!

Replace the old oxidized/pitted cast aluminum with these ProTunerz CNC 6061 billet pieces. Anodized thermostat housing and water necks.
We have added some useful modern ports that are labelled to avoid any mishaps. This  not only an aesthetic upgrade to your engine pay but a must in todays age.
