Overheating is common in poorly serviced vehicles.
My 1990 pick-up T-25 2.1 DJ WBX 160.000 km an still no rebuild...

The Wasser crank will not fit in the TypeIV, there is no way possible...

The Wassers did have some head sealing problems, due to people running conventional coolants, and this erroding the sealing surface.

You must run the factory "blue" coolant from V.W.

A properly built and maintained Wasser will outlive a Type IV 2 to one....

The piston were designed to promote "swirl" and to keep the combustion in the piston, to transfer the heat energy to the coolant system.

Now we're starting to see piston designs like the Super Squishy from ACNet that are "revolutionary in design" Hmmm, I wonder who had this Idea first.

The V.W. engineers where not dumb when they designed this motor, and alot of problems in past designs where changed in this model.

Hi Joe,
I just looked at prices for complete or core 2,1 DJ engines here and they are very, very expensive. Since you then have to do the machine work and buy a rather expensive piston/cylinder set if you want anything more than 94 mm bore, I experienced the venture more expensive then a type 4 in general. I reckon all the accesories (induction, cooling, exhaust) cost about the same if you want quality. Maybe the cores are more readily available and thus cheaper to get in the usa...
Make no mistake, I like the wbx/oxyboxer idea very much: Gerd Weiser in germany has build one, which has been tested in VW Speed magazine (great aticle) and one drove in the type 1 class in the kaefer cup with great succes, but cheaper or better than type 4, not so in my opinion.
I like the engine in original form even that much, that i think of putting one in a Type 3 squareback. Imaging: 112 hp with original injection, so its low for fitting under the hood of the type 3 and has great heating possibilities, when made fit... I'am still a bit worried of the cracks between the cylinder heads that they all seem to have and live happily with...,still...
Like your work with the obx engines though; its much, much better than T1, that's for sure.
Greetings,
Walter

I talked to Gerd Weiser when I went back to Germany in 98. I asked about the OBX.
He told me that it was not cheap. Maybe it is cheaper now.

Whats not cheap? the conversion, the aftermarket parts or the "mother" engine?

They are not so expensive here.When we can find them that is :)

I am thinking about this converson myself. Keep the info comming!!!

The "MV" 2.1 short block cost me $55 USD. There are many 1.9 engines I just do not even want to bother with. Local VW junkyard has a 2.1 longblock for $200, good to go.

Do not pay a premium for these motor cores.

Normally the cases and cranks do not even need bored or polished. As the heads blow before the bottom end is tired.

In my situation the T5 OXY should cost less than a comperable T1 2110 stroker. Much less.

Also consider that you might be able to sell some of the WBX parts that are useless and come out even.

i may seem like an idiot, or just a real newbie, for asking this, but can someone give me a complete step by step checklist for converting a stock wbx engine into an obx and putting it into a bug?

1. find good wbx engine
2. tear down and cut water jackets off ....?
3.

Although this thread is three years old (sans the last reply), I have read it just now for the first time.

Ironically enough, I was going through my stacks of old magazines to weed out the issues I no longer wanted taking up space. There was one issue of VW Trends or Hot VWs that had an article on this very subject. I'm pretty sure I kept it.

Is there any way I can scan or quote this article and stay within ethical and legal guidelines?
