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:

Cooling System


- Radiators

I have seen conversions with the following:

Griffin Radiators
1988 VW Jetta GL
VW Sirocco's
Honda Radiators

Not sure of the minumim size radiator you can get away with.

- Radiator Mounting/Shrouds/Fans

Here are a couple of radiator mounting pictures (with and without shrouds)

Engine Mounting

- Stock Subaru Mount Points

There are some very creative and effective mounting solutions out there. Here are a couple I have seen.

TonyAKAVW - U-shaped mount bar.

DBCooper - Modified Renegade Engine Cradle.

- Aftermarket Mounts

Outfront Motorsports makes a mount which bolts to the bottom of the motor.

HeaterGuy:

Small Car Performance also make a similar mount (might be the same as the Outfront mount, not sure). Link

This is from Amenson's thread.
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.digitaldash.org-364-1284136187.1.jpg)

He modified it to fit to the stock 4cylinder engine bar.

Transmission Options

There are several different approaches to the transmission/CV options. Here are a couple of threads with further details:

Subaru transmission installation, Now it's a reality!!!

Subaru Transmission into 914, DAMN that turned out good!!

Subaru Transmission successfully installed?, This awesome engine needs a Modern Transmission

Axles for Subaru Conversion, 914 hubs ok?

Axle questions for a Subaru Tranny, Another Subaru conversion..



- Adaptors/Flywheels/Clutch

For mating with a 901 transmission, there are three options that I am aware off.

1. Kennedy Engineering (http://www.kennedyeng.com/vw_por.htm)
Package consists of an adaptor plate, flywheel, and pilot bearing.
- 215mm flywheel package for $540 (Clutch Package $431)
- 9" flywheel package for $540 (Clutch Package $354)
(Clutch Package includes Pressure Plate/Disc/Throw-out Bearing)
- Flywheel weighs 19lbs.

2. OutFront Motorsports (http://www.outfrontmotorsports.com/clutch_flywheel.htm)
Offer a monolithic flywheel (i.e. 1 peice) in both 8" and 9" diameters with adaptor kit for $480
Also have a 2-peice welded flywheel for $440
Multiple clutch packages ranging from $110 to $250 with a 6-puck disc for $80.
Also mention a dual clutch disc set-up for a light pedal.
Flywheel weights between 15lb and 16lbs
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.outfrontmotorsports.com-364-1284052723.1.jpg)
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.outfrontmotorsports.com-364-1284052724.2.jpg)


3. Renegage Hybrids (http://www.renegadehybrids.com/)
Don't really break down the adaptor plate seperatly on their website.
Includes Billet Adapter Plate, Custom 9" Flywheel, Kevlar 9" Clutch Disc, Stage Two 9" Pressure Plate

Some random images of adaptor plates, I don't know which manufactures.

- CV Joints/Output Shafts

There are replacement output shafts for the Subaru transmission to 914 CV joint.
Attached Image

There are the option to machine a set of 911 axles to mate up to the stock Subaru CV joints as shown by BIGKAT_83.
"The axles are 911. These are a large enough diameter to be machined on the transaxle side for a Subaru CV joint spline. This gives me a 911 large CV joint on the wheel end and the Subaru joint on the transaxle side. "

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.

(IMG:http://www.914world.com/bbs2/uploads_offsite/www.outfrontmotorsports.com-364-1284054502.1.jpg)

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

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.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i78.photobucket.com-364-1284134625.2.jpg)

Small Car Performance also sells a cast aluminum pan. Link

Features
* Thickwall alloy aluminum for handling the worst conditions
* Stock Subaru oil capacity (4.3 liters) or 5.5 quarts when filled to the later Subaru level
* Shaped bottom for superior oil scavenging
* Finned exterior for heat dissipation
* Heliarc welded screened oil pickup
* Stainless bolts with aluminum washers
* Comes with o-rings for the oil pickup and for the stock or our flexible dipstick
* 4 5/16" total height saves over 2 inches when compared to the stock Subaru oil pan

- 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.

Very interesting motor mount you added. Uses the stock bar/mounts? Im curious how the owner of that car likes that as with that power you would think you might need some better mounts.

Pretty good summary. I've been looking for a picture of the Rennedage mount. Looks like it uses the stock mounting points for the engine and trans.
