Description
This is a Japanifold that has been modified to allow for bolting on a T3 turbo. It features our CNC manufactured T3 adapter made from 1/2″ 304 stainless welded to a Japanifold.
Prior to modification, the manifold is checked for cracking and the head mating flange is surfaced to within .002″.
The purchase price includes the cost of the Japanifold, but if you have your Japanifold that you’d like modified, you can send it to us for a $150 discount.
Details on the adapter:
CNC machined from 1/2″ 304 stainless
As compared to other manifold adapters, this adapter is CNC machined on both sides which gives a smooth flow transition for exhaust flow. It is tapped for M10 x 1.5 studs, which are necessary to support the weight of heavier turbos.
The advantage of a weld-on flange vs machining the lip off of a factory manifold is that the additional height provided by the weld-on flange gives more clearance for the rear engine mount on FWD cars. Also, on stock manifolds the lower holes are pass throughs and are a large diameter. When these holes are tapped for M10 studs, there is minimal thread engagement. Minimal thread engagement will lead to loose studs as thermal expansion causes the threads to pull out.
