Thought you may all be interested in this, I helped my new friend pat do an install a short time ago here in Boulder, he posted lots of video including one of a run up I- 70 post install
Here's video # 1

You can just follow all the other links, Pat did a great job! |

To be clear - yes the zetec is a North American engine. It's production and distribution is not, however, limited to North America. As noted by others, low mileage zetecs are relatively easy to find here in 'merica.
Parts are amazingly easy to come by, and maintenance is a breeze. |

Parts for the Zetec are available worldwide off the shelf at very reasonable prices. The Zetec was designed as a "World Engine" and was offered in every market that Ford is present in worldwide.
The engine is very simple to maintain. I recently changed my timing belt ($18.95 off the shelf at AutoZone) in about 25 minutes without removing the engine from the van. This brings up another nice benefit of the Zetec, which is that it is a non-interference engine (unlike most Subaru's).
I have a 2006 Forester that I drive in the winter when the roads are salty and my '85 Westy goes into storage, so I am no stranger to Subaru's. In fact I was very close to installing a Subie 2.5L in my van before I found Bostig. After going down to meet Jim and Brady and driving a Zetec Vanagon I never considered anything else.
I have about 8,000 trouble free miles on my camper now and I will be installing the Bostig v2.0 kit into my '87 Wolfsburg next month so I can get ready for the Bostig Turbo Kit!

Yeah their website wasn't really specific about those thing. Although i did figure it was a north American engine.
I'm basically sold on this conversion (i would like to find the "sport" version) but i really like the completeness. It seems the cost it right around the same for a subie and seems miles ahead.

That intake, however, looks mighty restrictive. Like running a race while breathing through a straw!

Does look kinda odd? 
The stock Vanagon intake is a snorkle that runs up to the passenger side intake vent though.

For those looking for more photos, a shot of my engine bay.
As for the intake - can't say that it's restrictive at all. Curious what make you think that it would be so? My intake has the same hose (as you can see) plumbed into a modified Ford Focus airbox that's connected to my syncro snorkle. It's a large diameter hose there there are no kinks or tight corners. Nothing restrictive about it as far as I know. |

All the ribs in the intake tube slows the flow of air down.

as an Oregonian (splitting time between Portland & Prineville) I have been thinking about the Subaru-urabuS conversion. I own & have owned enough Subarus to feel comfortable about the reliability... However, what I'm looking for is the reliability, better gas mileage & more power...
Money's a concern for sure but would consider doing this change myself... if it's conceivable.
Later,
Peter

From what I've been told, this is true in theory but not in practice. The bostig guys are pretty thoughtful about what they're putting out there, and I believe Jim has considered the theoretical drawbacks of the ribbed intake, tested the question, and found it to be a non-issue. Not sure of the details, but if you're curious I'm sure we can find out more. |

As an engineer (with a lot of background in fluids) I'd say it's not theoretical...It's turbulent vs. laminar flow. Most intakes are designed to "remedy" turbulent flow within a few pipe diameters.
As a Soob convert, not bashing the Zetec. Just making a point. Maybe they were leaving room for a turbo:-)).

Agree that turbulant vs. lamanir flow is real, I'm just not sure that turbulant flow through the intake is significant enough to "restrict" the intake in an appreciable way. I could be wrong. |

it's more a length and diameter issue in my mind. imagine trying to suck a 2leader bottle though a 3ft straw.
In other words, the engine has to work harder to suck the air in that it needs to operate which causes a signifigant loss of performance. That other intake was better, if not just because of reduced turbulence and length. Although it's placemean near the exhaust header is a whole other can of worms!

| that air intake filter for me in its present location would be covered in heavy dust after driving for 10 min. on some of the dirt roads I drive on ( a continual maintenance item )...anyone who lives in the southwest or drives on some of the desert dirt roads can atest to the fact that it only takes a few minutes to get the entire motor bay area saturated with dust... |

I'm am starting the conversion soon and I have it set up to use the zetec air box that is tucked in behind the passenger taillight and then into the stock snorkel here are a couple off pics

You're correct on turbulent vs. laminar, and if these were race cars with spec limits vying for every bit of power, yeah we'd do another intake. But these are 130 horse engines for vanagons, and vanagon drivers. The ribbed intake tube was used to tame intake noise, the effect on power is less than 2%. The biggest problem with the intake hose is it's appearance as it causes speculation as to it's effects on power just like what is happening here, and the fact that since they are custom made we have to buy them in large batches as well.
Oh and the guess about leaving room for the turbo, astute.

Yeah guys in dusty environments definitely should go the airbox plumbed into the snorkel route over open element. |

Exactly, perception is the biggest issue. We could always fab up a straight mandrel bent intake, it'll be noisier, you could gain 2HP low-mid, and maybe even 4HP at high revs. It'll cost you $180-$250 more, most will say it isn't worth it, which is the call we made. Although as we all know, bling always makes an engine more powerful, cool vendor sticker can even shave a few tenths off your ETs  |
