It's where you do a little machining on the manifold and gasket so it matches the exhaust ports on the head exactly for smoother flow.

I'm going back to NA till I fall on a little more cash. Having the intercooler in the intake is definitely gonna add 20 horsepower to the wheels!

Well, I converted back to naturally aspirated. Still running megasquirt and a 2.5" enthuza catback and OOOHHHH MYYYYYY GOOOOOOOD ITS SLOOOOOOOOOOOOOOOOOOOOOOOOW.

The 3.9 rear end killed all the acceleration it had N/A.

I'm just gonna drop a couple big ones on the ETD tubular manifold.

If you do not trust yourself, any machine shop will pull those studs for like 50 bucks. In addition, I would recommend dropping some coin on a damn flex section.

you can see from the residue left on the flange that the turbine inlet is larger than the port on the manifold itself. Opening the hole up to match the turbine inlet might be good for a point or two of efficiency.

Must be a GOOD friend. I couldn't ever imagine going back to N/A...even with a V8!
