4KCS Upgrade

[Glenn.Corbett at molson.com]

I have a 87' 4KCS with the 2.2 which I would like to upgrade. The 2.6 from
Eurospec looks indicing, but can I use my existing cyl head or must I
retro-fit another unit? If I was able to locate a 2.5 from a EuroVan would
this bolt in with or without 'extra parts'?

I've heard about the NG and NF motors, what are these and are they a better
alternative? My 4K is manual/FWD so I will be more then happy with
170-200hp.

Your thoughts????
