I came from a Driftmotion modified manifold. Picked up an open scroll T4 manifold for my 1JZ.
The CXRacing manifold fits VERY well. The flanges require ZERO machining. They're perfectly flat out of the box.
Also, the head flange holes on the CX piece line up much better than the Driftmotion flange and did not require ANY hole enlarging, redrilling or shorter studs. Nice work for a china manifold!
My only complaint is cyl #1 runner. As you can see, theres a small 'rash' I had to make. It doesn't clear the thermostat housing bolt. Needs a little massaging via 20 pound sledge hammer. Seriously. Don't try without at least 20lbs. The manifold runners are STUPID thick and make the old DM manifold look like it's made out of aluminum foil.
Ignore the little sandwich plate sitting in between the manifold and turbo
I wouldn't waste my time reinforcing these manifolds like DM does to theirs. The runners are such thick gauge it's pointless.
It comes with a weird flange for the wastegate. I'm sure someone knows offhand what the rectangular waste gate brand the flange fits but it doesn't fit mine. I run a Tial so I had to chop it off and weld a small 1" extension to keep the wastegate off the motor mount and make room for the massive Tial 60mm wastegates fins. Excuse the ****ty welds on my wastegate pipe. The rest of the welds from CX are very good.
