ntroducing our new 13B T4 Split pulse manifold for FD RX7.
This unique manifold has runner separation all the way to just before the wastegate valve face.
This has been a VERY complex manufacturing hurdle we have finally overcome.
By running a single wastegate you can also cut down on cost as well as an easier setup to thermal manage.
This manifold was designed to accommodate the @garrettmotion G40 turbo, which will leave you space for other smaller units.
The 13B manifold also features wastegate machining to suit a Gen 5 @turbosmarthq 50mm Wastegate, though as you can see we have provided a cut line if you wish to run a 60mm for any reason.
