which block fits directly onto a 1.8 DX kjet head?

Hi All,

I'm helping a friend get his project mk1 gti cab on the road and at present the current DX engine is burning a lot of oil …Cyl 1 +4 are down on comp, wet test improves this so  its likely to be piston rings im guessing…

ideally he wants to keep the car a 1.8 Kjet so doesn't want to do an engine swap, however we can't seem to find any complete DX engines or complete blocks we can drop in for a sensible price, so until we get around to rebuilding the original block in the future (he plans to keep the car for quite sometime) I was wondering if a mk2 carb block will bolt up and work with the DX head whist retaining everything as it was i.e Kjet,oil cooler…etc etc.


I've had a look online and seen several 1.8 carb engines removed from mk2's or mk1 cabs going for reasonsible money hence I thought I would ask on here before we proceed…

If the above is possible can someone please confirm the following:


1. how will this effect power?

2. would anything be needed to adapted for the block/head to fit i.e the 2.0 8V requires a dizzy kit from TSR

3. Anything else we need to be aware of or may have overlooked in regards to replacement options for a complete block?


Thanks you advance!

Not 100% sure but I think the 1.8 carb engine block (EX) is the same as the fuel injected engine block (DX) so I don't think you will see/feel any difference in performance, if your engine is worn out you may find an improvement…….

Mk2 Golf, Mk2 Scirocco engine blocks should be a straight swap.


Looking in the Haynes manual.

DX  Bore = 81mm - Stroke = 86.4mm Compression ratio = 10.0 to 1
EX  Bore = 81mm - Stroke = 86.4mm Compression ratio = 10.0 to 1

Thank you for the info…greatly appreciated!

Can someone confirm how the EX short block is different from a DX?

will there be a drop in power?

will the DX oil cooler assembly connect up?…or anything from the DX which won't fit?
