WBX 2.1L fuelinjection on a 2L type-4?

[IMPI]

I have now built 2 aircooled engines with wbx injection works well if you combine parts one engine was turbocharged and although the Fuel injection could not really cope well it worked enough to give 180 hp

Thanks IMPI!
Could you advise me on what tempsensors etc. you have used for your engines? Just the stock typ-4 sensors or something else? Partsnumbers etc. would be great.

This is what have happened since september last year:


In December I finally got the cooling tin mounted so I could start fitting the Wasserboxer fuelinjection plenum to the manifolds.


Had to bend the manifold tubes about an inch on the righthandside of the engine backwards(the ones closest to the camera). Otherwise the plenum would have sat a bit twisted and also to clear the intake rubber from AMM to the throttlebody.



The manifolds to the left bent, and the plenum on its correct place.

January this year:

Welded the mounts that bolts the WBX plenum to the type-4 case.




And test fitted WBX injectors I have.

In the mid January I started working on the exhaust.

Bought a pile of stainless steel 90 degree tubebends.

40mm OD and 37mm ID.



Had earlier bought a set of lasercut flanges:



The started to make my own exhaust.

Finding shorter exhaust studs was not the easiest task... They were M9 in the heads and M8 at the flanges...

So my Brother make me a set.



Here the first part of the exhaust is finished in mid February.





As you see in the last picture I also had plans on teststarting the engine with carbs first as I had a set of Type-3 carbs laying around.

Got some more work done by the end of february:

Mid march I myself out to the garage again with new welding gas. 8)
As I was out pretty late I didn't take the time to finish off all welds but had to leave them as in the pictures. You start to see the finished product though.
