914World.com _ 914World Garage _ Time to start on my big Type IV motor

Posted by: veltror Apr 5 2010, 06:04 PM

Gentlemen,

Some years ago, April 98 to be precise, I bought a 2.6 L stroker kit from European racing, with a J Cam 307 Dur. The plan then was to put it into my 1303 Beetle, but things changed and i never did anything, but I did source some parts.

Those who have been following my British Rustoration thread can see that I still have a lot more work to do on the body but I think it might be time to start putting th lump together. Now I thought I had a 78 Stroke crank and 103 pistons so I should get a 2600, but on inspecting the pistons they say 104. This makes it 2650, I think it may be too big besides petrol is not free here like it is in the US.

The good news is my new Type 4 case looks ok, although I do not like the oil breather bit so some machining will be needed here. The case has a part number of 071101101 so it look like a late air-cooled case.

Plan is to go with a microsquirt system since carbs would need to be 45's which is more cash, might as well go modern-tech.

I will update this thread as things progress, please feel free to add comments or criticism .

Very nice, keep posting.

Run the pistons, 1mm won't save you gas.

The case is a late bus or vanagon case. Spec it out good as they tend to be beat from pushin the heavy bus around.
Sump P/U is shorter and will need a slight mod if running a 914 windage tray.

That will run with 44 webers (45dells) just fine, the MS will cost you more if you use ITB's. Although I like PEFI, carbs will always be cheaper.

i forgot to say, the case is brand new, and yes I will use ITB's and of course your trigger wheel, will have to see what the MS system costs out to...

Thanks for the comments.

Cool about the new case, the only issue will be a dipstick, but no biggie.

Wrong Mark on the trigger wheel;)
