Hey guys just wanted to share a performance manifold for the D Series that was fabricated by us and works. We were truly impressed with the Power our d16z6 put down. We seen close to 100 hp increase from last years dyno session on the same 18 pounds of boost over a skunk2 off the shelf manifold.

Runners went through a weld process and port and polish to achieve a smooth transition from the large oval runner down to the small d16 runner on flange.

A shot of velocity stack runners, inside and out of sheet aluminum plenum.

Finally the finished product fitted in our D2B EG coupe with dyno numbers at 18lbs of boost. Made 488whp spinning up top with 100whp over the skunk2 intake manifold at same boost. More dyno numbers soon at high boost stay tuned.
