2JZ-GE T4 bottom mount exhaust manifold

HIGH EFFICIENCY
Don’t cook your engine bay! Keep heat where it needs to be – the turbocharger. Our log-style exhaust manifold is perfect for a responsive, efficient setup.
To further improve spool, check out our Quick Spool Valve!

EASY PIPING
Our bottom mount design enables short downpipe routing without any tight bends.
The Intercooler piping can be routed directly into the bumper. No need for cutting your chassis!

DURABILITY
Our manifolds are investment cast from SS304 with a wall thickness of 5mm – strong and reliable.

NO BOOST CREEP
Centered 44mm wastegate flange for convenient installation and high wastegate flow.

TAPERED PORTS
The ports are tapered to match the stock exhaust ports on the head. The taper can easily be removed.

EGT SENSOR
Our manifold has a predestined EGT sensor location at the top where you can mount your EGT sensor. Our manifold will not come pre-drilled and tapped anymore due to low demand.

TEMPLATE FILE
For testing whether your turbocharger clears your chassis in combination with our exhaust manifold, we have created a template file, you can simply print and cut out for testing.

(make sure to print “original size”, material thickness 4mm)

NOTE
For better fitment you should rotate your water neck by 180 degrees like shown in the picture. No additional parts are required.

Some water necks have a tab which has to be cut off in order to be rotated.

For better clearance around the compressor housing we recommend to upgrade your engine mounts, which you should do anyway when boosting your GE.
The Turbocharger shown in the pictures is a BorgWarner S364-SXE. There is still plenty of space around it.
Fits even with our Quick Spool Valve into a Lexus IS chassis.
