2.2L & 2.5L SUBARU VANAGON CONVERSIONS
At Small Car Performance we are extremely proud of our conversions! Unlike many of our competitors, we completely rebuild all our Subaru engines from the ground up. Every seal, bolt, and flange has been meticulously cleaned, inspected, and when necessary, replaced with more modern and reliable alternatives – almost like it came from the VW-Subaru factory!
We know we are not the cheapest option you have, but we believe there isn't a conversion on the market that compares with the fit and function of SCP's. From our functional and efficient cooling system to the ground clearance saving cast aluminum oil pan, we’ve designed all our products and services to get your Subaru Vanagon conversion up and running quickly and performing more reliably than ever.
ABOUT THE ENGINES:
In short, the Subaru engines we use in our conversions are impressive. They are state of the art engineering with five main bearings, four valves per cylinder, and two overhead cams. They feature an engine management computer capable of learning as you drive with input from crank and cam position sensors, knock sensors, oxygen sensors; as well as controlling the spark, fuel injectors, and timing. They have no distributor, cap, or rotor and the 2010-2012 motors don't even have plug wires!
The outstanding reliability of these engines is evident by their popularity in light aircraft. The 2.5L Subaru engine makes 165-175hp and is perhaps the perfect Vanagon engine. It has great torque throughout the RPM range. It easily keeps up with traffic, even in the heavier Westfalia and Syncro, and runs extremely well with both the manual and the automatic transmissions.
Fuel mileage has proven to be better than the stock WBXer engine - even with the additional power of the Subaru engine - and all run beautifully on regular gas. We can use almost all of the 2.5L motors up to the 2012 Subaru models. The 2010-2012 is a particularly torquey motor and is the perfect engine for the heavier Syncro and Camper Vans.
As a horizontally opposed four, the Subaru motor fits like it was meant to be there and all the original Vanagon options can remain functional; cruise control, air conditioning as well as the Syncro skid plate.

The van is running great. I put it into 4th leaving Tacoma, and never geared down until the border. There is a hill on the main road of our island that the other Syncro Westy on island with a Waterboxer performance 2.5L can almost make in 4th. This van sails up the hill in 4th gear. I'm very pleased and barring the unforeseen I'll be back next fall or winter for the brake up-grade and the drive shaft with the de-coupler. I'll do my best to send more vans your way.Dave
AFTER 200,000 MILES
I wanted to give you a progress report on my Vanagon to Subaru conversion that you did just before Christmas. First, as you know I have always kept close track of my '87 Vanagon's gas mileage. For the entire six months before your conversion I averaged 17.5 miles to the gallon with the 2.1 VW engine. I now have 100,000 miles on the 2.5 Subaru engine you put in and I am happy to report I am averaging over 20 miles to the gallon! And that is with 50-50 city/highway driving. I am sure I will do even better this summer when I take my cross country trip. The engine is running beautifully, and it is so quiet at idle that I sometimes have to look at the tach to make sure it is still running when I am at a stop light. The extra power is the added bonus that is hard to believe. I remember that I use to have to downshift to get up most of the hills in my neighborhood. Even in cruise control on the highway the engine would lug and I would have to downshift up the steeper grades. Now if I set it at 65 it stays there with no sign of slowing down. I guess the greatest statement I can make is that I have grown so accustomed to my new Vanaroo that I hardly notice that the change was done. Except for less noise, improved gas mileage, and the acceleration, one wouldn't notice at all. Thank you for being so helpful with the conversion. You were always there to answer questions and to make things right if I had any concerns. I will gladly answer any questions anyone might have about the conversion you did for me. I really think your onto something big, and I am proud to be the first 2.5L Vanaroo in Western Washington. Dave
Update: Dave stopped by to check out our new shop and let us know that his 2.5 now has 220,000 miles since the conversion and is still running strong with no signs of slowing down anytime soon!
