DOC Race Nissan RB20 RB25 RB26 top mount T4 w/ MVR wg, Fits Skyline and S chassis
Doing a single turbo swap on your RB26DETT? Or perhaps upgrading to a larger turbo on your RB20DET, RB25DET or even RB30 setup? You'll want to consider a top mount manifold from DOC Race.
These tubular manifolds are designed to optimize exhaust gas flow into your turbo's turbine housing. This results in higher efficient turbo setups allowing faster spool time (reducing turbo lag) and additional torque.
This particular manifold uses a larger T4 flange that will mount directly to your twin scroll turbo. In addition, routing all the exhaust gas from around the turbo at your desired boost pressure through a 44 mm wastegate flanges. This flange is setup for a TiAl MVR wastegtae V-Band. Other brand wastegates that use the same flange can be used as well.
This manifold will work on the following chassis setups:
(Obviously, always do your own measuring when it comes to engine swaps as engine placement can differ between mounts and chassis)
