Subaru Engine Conversion Wiki, Let's compile all the knowledge into one thread... Options

[Britain Smith]

I have been going thru several of the threads regarding Subaru engine conversions to learn about the different ways people are performing the installation. From radiators to CV adaptors, there are several paths to take. Lets try to compile all that information into one thread. Anyone can contribute and I will take the information in the thread and update the top few posts with the details.

Here is a list of 914 Subaru related Threads:

Oil System

- Different Sump Pans

Outfront sells a shorten oil pan for $270 which included a shortened pickup tube. They also list a mid-engine pan for $370, but I am not sure what the difference is.

Here is a nicely modified pan from TonyAWAVW with side kick-outs.


Bugat5Speed (http://www.bugat5speed.de/en/) offers a cast aluminum sump.
Details:
Some Product Details:
-Works with EJ 2.0, 2.2 and 2.5 blocks
-The sump is sandcasted like all our other parts.
-The capacity of oil is 4,25 litres (that´s only 0,25 less than original). If you shorten an original sump you loose about a 1 litre.
-It is very stabile (you can put a hydraulic lifter under it and lift the car), so nothing happens if the car is low and the sump hits the floor). If you have the original sump, that´s virtually impossible.
-The cooling properties are much better than with the original one. Water temperature is reduced by about 10 degrees Celsius, if you switch from original to the bug@5Speed sump.
-The pick-up tube inside the sump must be modified (shortened). But that´s no big deal. Anyone who does such a project will easily handle this task.
-The original dipstick can be used, but must be shortened a little.
- Overall dimmentsions are 275 x 320 x 120 mm (length, width, height).

*** One key point, these sumps will interfere with the stock motor mounts, if your using the RJES conversion. Will require modifications of mounts.

- Dry Sump Set-up

Not sure if it is needed, but some have converted to dry sump set-up. The expense of this set-up can exceed $3K and is very complicated.

Tony's pan has the extensions on the front and rear.

The outback pans are probably for a vw type install (taildragger) or the midengine. The sump will be better in each instance for the application. There are at least two custom aluminum pans available. One is bugat5speed it is cast aluminum. I'm not sure the bugat5speed pan will work with the smallcar mount as the aluminum pan looks too wide for the smallcar mount. Also be aware of the direction of the baffels in the pan to stop the oil from leaving the pickup on aceleration and braking and cornering.
