wbx to beetle ?

Is that a stock WBX exhaust too?

Any chance of some pics of where the stat housing is with the engine in situ?

al, that's the T25 '86 on exhaust primary setup, very expensive, even today's replacements supplied are good quality tho, and hard to improve on power wise, made for mid range in a heavy T25... the early type 'stat housing is integral to the pump by the no 4 exhaust stub unfortunately, the late pump is more efficient, that's why V.W changed it, again, '86 on and injection models, gives a full cross flow coolant path for cooler running, you can then use a remote 'stat junction pipe housing, hope that helps... regards..

Thanks you on the smoke much? Pintage and brain picking some time?

[spannermanager]

al ,cool, i'm in Kent apart from work time, more and more , done my time up there!! but ill shout you wasser guys when im gigging in the s.e area , Brands has a good bar! nearly there, the 2.5 is being naughty, air bubbles in the d/sump system, sounds great and revs like a super bike apart from that, but got it sorted today.... i think,,,, i have a back plan up if needed. regards...

Can you post a vid of the engine.

Hi

This is a reply to a post on shoptalk that I did when I was running a 2.1 WBX in my old 1302

==============
Wasserboxer in a Beetle.

The Wasserboxer has received some bad press for headstud problems; coolant leaks and assorted other woes. These problems seem to occur when proper VW servicing techniques are not used, VW coolant and distilled water.

The Wasserboxer motor in my VW Beetle has been looked after as far correct coolant is concerned; I also use distilled water mixed with genuine VW coolant. I fitted an Oettinger 85 thermostat instead of the standard 87. These don’t seem to be available anymore so I have modified a Mercedes one to fit. The top part of the thermostat is the same as the VW one, but the lower bypass part has a larger diameter flange. This can easily be made the correct diameter by first marking out the correct diameter circle with a pair of dividers and the grind the flange down to the marked circle, it doesn’t need to a perfect circle. I also got rid of water-cooled oil-cooler as I have heard that they can fail. I’m running an air cooled oil cooler with a Setrab thermo block at the front of the radiator.

As far as the rest of the motor goes it is extremely reliable, I give my bug heaps. I have bent one Scat pushrod (I’m now running Berg ones) and had 2 water pumps fail in about 100,000 Ks since 1988 and have had a few coolant hoses fail. My bug is also in constant state of improvement, so some things are always changing.

The Wasserboxers use 2 styles of cooling systems, basically the 1.9 and 2.1 litre style. I prefer the 2.1 style.

Fitting the motor is much the same as fitting a type 4 motor, same style of flywheel. The thermostat housing which sits above # 3 exhaust port needs to have some body clearancing. The water hose that runs from the water pump to the thermostat housing needs to be modified at the water pump end. It basically would run straight through the left-hand rear bumper bracket. Any Beetle exhaust can be used, #1 & # 4 exhaust flanges need to be rotated 90. In the engine bay I used basically the whole Wasserboxer cooling system and condensed it to fit. You will need a steel coolant ring main as the plastic one cant be shortened easily.

The coolant runs to and from the front of the car via 1.5-inch stainless steel tubes. These follow the chassis bolts along the bottom of the heater channels. I have just upgraded my radiator with a modified Ford Transit radiator. After some gentle prompting from a fellow list user MARTINSR, yesterday I went out and bought an after market thermo fan from Davies Craig http://www.daviescraig.com.au/. It’s meant to be used for a 5 litre V8 and pumps 2120 CFM, so far its working really well, we are having 40  + days down here at the moment. I previously used a BMW radiator and Audi 100 thermo fan. Cool air is brought into the radiator through an A/C louvered front apron. I removed the deformation plate at the front of the chassis to allow more air in. I had to also remove the spare wheel well and I just left the rounded edge for a bit of extra strength, I supplemented the spare wheel wells strength with angle steel. My radiator is around 550 mm across and 450 mm deep on the cooling surface, it’s actually a little wider where the tanks are on the side. The radiator sits on a U shaped holder right down on the chassis and comes very close to the under bonnet and leans forward about 5. I fabricated a sheetmetal alloy housing to guide the cooling air in and let the heated air exit over the front end. I basically used some angle aluminum for the edges and then filled this in with very thin aluminum sheet. In case you hadn’t already realised my bug is a super. I have seen radiators fitted to standard bugs but I have no experience with this. My spare wheel sits on top my fuel tank on a bracket attached to the strut brace.

Original heater channels were retained and warm air is directed from a Toyota troop carrier heater core under the rear seat opposite the battery, to the interior via early Audi 100 brake cooling fan on the right hand side and via the troopy fan on the left hand side. I have used the rear seat heater cable to operate heater shut off valve.

My Kombi motor was purchased new in 1988 and is 2.1 litre its DJ engine number type 10.5:1 compression, 112 BHP type. I original ran the motor with dual webbers Berg cam. In preparation for a turbo the motor was been decompressed to 8.0:1 and the cam changed back to standard. 1.4 berg rockers are used.

I’m using an after market EFI system with the factory manifold, the injectors in the stock manifold sit in a horizontal plane so the side panels in engine bay that the engine tray seal fits in need to be modified or removed.

Looks awesome - rock solid idle is great

Good to see you got rid of that decklid mounted radiator.
