Mid-Frame design fits all turbos, including 10" compressors, EFR and has no clearance issues! T3, T4, Mid Frame, T6 all fit on our ProSeries manifold!!

Our team at have been involved in the 2JZ world for quite some time, with our founder - Mark owning the first stock block 1000 HP Supra in the world all the way back in 2001.

For years, people have been asking...why must you pay $1700+ for a turbo manifold? I understand it takes time to engineer, test-fit, build a prototype, then build a jig, just to offer a header. This costs money and quality fabricators (check out our x-ray verified welds!!) are not cheap either. Our goal was under $1000 for a world-class hand-made manifold for the Supra community, which we have been a part of longer than any business on the planet.

Our 304SS tig welded 2JZ "mid-large frame version" exhaust manifold scavenges like none other on the market, with efficient runner designs and a proven collector. They are finished in a brushed-stainless "raw-look"; but we can ceramic coat them at extra cost, if that is what you require. They are robust, handle heat cycles correctly and are guaranteed to perform.

These work great on smaller T4 turbos like the Precision 7175 as well, that benefit from larger diameter runners.

The No. 1 runner is designed differently over our standard ProSeries manifold, and has a lower swept design to the number one runner. The overall turbo collector region is reconfigured to sit over 1/2" lower in the engine bay to provide maximum clearance for larger compressor cover turbochargers, while at the same time providing for an efficient overall layout. We also include a 3 year warranty on all ProSeries exhaust manifolds sold!

The design clears the shock tower and is the single best value for a manifold specifically designed for the traditional GT42 or GT45 style turbos. Please note that you will have to use a lower water neck rotator or some other solution as the larger turbo compressor outlet needs to come out there. There is no way around this.

If you require a TiAL, Precision flange, or other branded flange welded in, this is available as an option in the drop down menu.

If you require another type of wastegate flange welded, please select "Other" in the drop down menu and make a note in the comments section of the type of flange required, and our staff will contact you to confirm details. If no wastegate flange is selected, you will receive the manifold with the standard length wastegate tube "open" to mount whatever you want.

This version is designed specifically for higher horsepower turbochargers that utilize mid-frame or (very large) compressor housing diameters (9-10"). Fitment is perfect, so why spend $2000 on a mid-frame manifold when ours is just as nice, flows incredibly well, and is priced for half the price? It takes us about 14 days to build our mid-frame style manifolds, so plan accordingly.

These are single gate designs with a 44mm or 60mm diameter gate tube, which is the standard size for the Precision 66mm gates, as well as those offered by TiAL and HKS. If you require a dual gate version, these can be built for an additional $150.

Please be aware that there may be fitment issues with the dual gate setup in some cars. Although we can weld the wastegate flanges on by request, please note that we cannot guarantee fitment with your setup, as minor modification will most likely be needed.

The refresh kit for 1JZ engines will take a bit longer to ship out as we source the needed gaskets. Usually we can have one of those kits ready in 1-1.5 weeks
