Just a thought from a twisted mind......Anyone ever adapted a Lycoming/Continental cyl to a VW type motor?  Granted you'd go lathe crazy,
but if you started with a inexpensive non air worthy high quality cylinder assembly.....just a thought.




P.S. The term 'cylinder head' was been omitted intentionally.  Wink

if you see on the modern motor bike engine they have small stroke, big bore and long rods..
think maby to slow the piston down so it can suck more air/fuel in..

Hi Jago,
This is Fredrik and I think I know this car. Is it the same Chris has or had some involvement in when I was in Poland some years ago?
Looks good in any case and wishing you good luck!

Hello Fredrik!
Yes, you're right, that's bugster that belongs to Chris, I'm only helping him to get it running again after all those years. It's scary fast. And we're also doing a lot of other vw stuff so it's getting beter here.
BTW that guy with the head almost in your car - that's me. Damm that was a long time ago. (This is the photo from your topic on shoptalk)

Hi Tim
You can get a 94mm bore comp elim headed engine in with out messing the engine bay up so no reason you can get a 4inch modified comp headed engine or a jpm headed engine in there,just not going to happen with angleflows for a variety of reasons

Engine width is dependent on stroke not bore -- to narrow up my 2919 I moved up the wrist pin location into the oil rings and still I'm at 34 inches (with a 90mm stroke) and the stock engine compartment of my ghia is only 28"
