Default IBR modular intake manifold

IBR's modular intake manifold is certainly unique looking. The red portion adds plenum space over top large velocity stacks. The manifold provides "shower-style" port injection into the top of the bell mouth to get the most phase change and cooling benefits from ethanol for the intake charge. This should provide good gains over their BRZ intake manifold kit. They will be releasing further details and power gains "soon". Price starts at $1,499. Available in December 2019. Other powder coating colors will be available.

The shower-style fuel injection is popular in motorcycles and F1 engines. By injecting the fuel at the top of the the plenum it allows for more time to cool the intake charge and better fuel atomization (air/fuel mixing). The cooler, more atomized intake charge should provide better combustion, more power and less pre-ignition/detonation.















Hopefully an easier solution is developed for the electronic control of the secondary injection.

They will also be releasing an EJ version.

Pretty sure it would fit the stock hood, not sure any aftermarket hoods offer more clearance anyways? Maybe Varis'

I'm a total newb on secondary injectors, are they always on? Can they be activated at a certain boost level or throttle %? Or are they just always dumping a crap load of fuel in no matter what.
Not sure how the current BRZ manifold works and if this would change anything with the secondaries

And do the secondary injectors' fuel controller talk to the flex fuel sensor or the Cobb AP to inject fuel based on ethanol content?

I'm more curious if it'll still fit a Marsh composites hood lol

Should help prevent carbon/gunk build up on the valvetrain too...

Interesting design. I'll be sure to check out the power gains.

I feel like this will be more benefit to Built block rather than stock.

gonna have to relocate the oil filter by the looks of this shot... new FMIC piping routes as well. I wonder how many other parts have to be relocated and the final cost ends up being with all the required changes to make this fit and work properly? Yes I assume it would be a waste of time and $$ for this on a stock block as for much cheaper you can get WMI to help clean the valves.. This, IMO, is when you rock a much larger Turbo and need added fueling (which would take the power beyond stock block internals threshold). keep the info coming...
