SCP is proud to announce our support for 4EAT transmission conversions for Vanagons. This kit is a matched and proven set of parts that takes the worry out of building a Subaru powered Vanagon. No scouring the internet, fabricating parts, and worrying about whether muffler “A” will fit with bracket “B”. You will be rewarded with a finished conversion that looks and drives better than the original in every way - like it came from the VW-Subaru factory!

The kit is compatible and designed specifically for a 2005-2010 Drive-By-Wire EJ25 Subaru Motor and 4EAT Transmission. This includes all peripherals to allow for either a professional installation or the advanced DIYer.

The following parts may be necesary to finish your conversion but are not included in the conversion kit. Please give the following a read to determine what additional parts you may need. 

Transmission Coolers: We reccomend upgrading the factory VW automatic tranmission cooler after upgrading to a higher power Subaru engine. We offer two automatic transmissions cooler kits. Automatic Transmission Cooler Kit - is a basic kit that offers some improvement over the stock cooler. Transmission Cooler Supreme is our advanced kit that uses forced air to keep your transmission as cool as possible.

SCP Vanagon Aluminum Coolant Bottle: The SCP coolant is designed specifically Subaru-Vanagons and has lots of sex appeal. 

Stainless Steel Coolant Pipes: Early watercooled Vanagons (pre-1986) came with metal coolant pipes that run from the egnine to the radiator. Over time these pipes rust and should be replaced. If yours are in good shape then no need to replace. Late Vanagons (post-1985) came with plastic coolant pipes that almost always fail. These plastic pipes must be replaced. 

Stainless Steel Exhaust with Metallic Catalytic Converter (Two Oxygen Sensor Ports): This exhaust kit takes care of your exhaust after the headers that are included in the conversion kit. You'll recieve everything you need to finish your exhaust system. Click the link for more details. 

Power Steering Pressure Hose: You'll need a power steering hose in order to connect the Subaru power steering pump to the Vanagon power steering lines. We offer a standard Power Steering Hose and a Quiet Power Steering Hose. The quiet hose is offered as the Subaru power steering pump tends to be louder than the origonal Vanagon pump. 

Tachometer Faceplate Upgrade: Once you have modified your tach signal to work with your Vanagon tachometer you will need to update the faceplate in order to get an accurate reading. We have 7K and 8K faceplates available in black and white. 

Wiring Harness Modification: Small Car Performance provides multiple options for your Subaru to Vanagon harness.
