22RTE vs. 22RE Parts Differences

[nab856]

22RTE Exhaust Side

The exhaust manifold, turbo, and oil feed/return tubing are apparent differences. Turbo coolant feed barb is located behind the coolant pump (red arrow). Oil feed banjo bolt hole is located behind the engine coolant drain at the rear of the block (yellow arrow). Oil return engine block flange is just above the oil pan (white arrow). The block doesn't have oil squirters.

Upper Intake Plenum

I read somewhere the cross-sectional area of the 22RTE intake runners are larger. I would say that is debatable.

Lower Intake Plenum

22RTE fuel injector holes are larger and contain an adapter for cylinders 1 and 2 (red arrows). Once again, I don't see a difference in the cross-sectional area between the 22RTE and 22RE intake runners.

Oil Cooler with Hoses

Oil cooler is found under the intake plenums. The 22re doesn't have an oil cooler.

22RTE Piston

The turbo pistons are dished to lower compression.

That brings back some memories. I owned an '86 2WD SR5 turbo 5spd just like this one in the late 90's.

22RTE turbo exhaust manifold stud configuration

22RTE with naturally aspirated (NA) exhaust manifold

If your turbo is broken, you can convert the engine to NA configuration. Block off the oil feed and oil return holes (arrows). Then, replace turbo parts with NA intake, exhaust, and coolant components. The 22RTE engine is very modular. Alternatively, a supercharger or Garrett turbo work too. These mini trucks are much more fun to drive with forced induction. Unfortunately, the 22RTE is uncommon.

A Few More 22RTE Components

Air charge pipe (blue arrow). Toyota did not bother with an intercooler. Turbo coolant return barb (white arrow). Toyota used a specific air filter box for the 22RTE engine (red arrow).

Brake booster heat shield and bracket (white arrow). There is a turbo concealed under the other heat shields (bottom middle of the photo).
