As the 2jz’s little brother, the 1jz has always been considered the “underdog” of the Toyota range.
Combining our experience and knowledge of the 2jz engine from the past decade, Plazmaman has produced a manifold that will put the 1jz right up where it deserves.
We have spent a large amount of time concentrating on 2 things; the first being the port size vs taper, and the second being the manifold dome volume.
Plazmaman has supplied a number of these manifolds for 1JZ converted vehicles, with fitment being no issue. Contact Us if you’d like application advice or further information.
100+ psi can safely be distributed and flowed by any Plazmaman billet 1JZ inlet manifold.
Our billet manifolds are offered with, or without a provision for the factory IAC (idle air controller). A lot of race cars would not run the IAC, as most of these cars are run by independent stand alone ECUs.
Our 1JZ Inlet Manifold can be made to suit a number of our universal throttle bodies, which can be pre-selected prior to ordering, or you can select “none” if you have your own Plazmaman throttle body. This ensures the manifold is designed exactly how you require.
Included also, is our billet CNC machined fuel rail. Available in either single feed or dual feed.
This rail style accepts 14mm top feed injectors. The fuel rail comes with all mounting hardware, including stainless steel fasteners, CNC spacers/brackets, and the required male -6AN or -8AN fittings.

- 3mm smooth design plenum dome.
- O-ring port seal design.
- Measured long taper RAM tubed runner.
- Professionally Tig welded in house by our highly experienced fabricators.
