Description
This is our CNC’d T3 adapter welded to a Japanifold.
Manifolds are checked for cracking and the manifold flange is surfaced to within .002″.
The purchase price includes the cost of the Japanifold. You can send us a Japanifold core manifold for a $190 discount.
Details on the adapter:
CNC machined from 1/2″ 304 stainless, this is an adapter for converting a Volvo manifold to a universal T3 flange. This adapter is designed to be welded directly to the manifold.
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.
