NA 6 port half bridge build (zenki FC)

Tougemonster · 12-01-2012, 03:21 AM

So i kinda jus did my own thing cus everyone told me it wouldnt work well
I made a template using the pineapple large streetport for a 6 port
the template has a 32mm bridge on the secondaries only,its chamfered to about 34mm
the bridge is 5.5mm wide and the port goes to 1.5mm from the coolant seal and the housings are notched to match
Im still on a stock ECU i went with rebuilt injectors and used 550cc/min secondaries
I used cnc'd atkins aux port sleeves and just leave em open for now
all the intake runners were smoothed of casting crap TB was ported
I posted most of my buildup on the other forum.
