Cool.. Have you read though the link I posted about swapping heads around? All the poop should be there about swapping the 1.5 head on that block.. You'll need to use the 1.5 rod bearings and head gasket, as well as the little adapter doo hickey.. Everything else should be pretty straight forward.. AS far as the injection pump, you have any plans on what you'll be using there yet? There are some slight differences between the 1.5 and 1.6 pumps.. Not sure exactly what, I think most of it is timing and governor.. (maybe Burn_Your_Money can chime in here) AS far as interchanging a 1.6 pump on a 1.5 and visa versa I've never really been able to tell much difference.. You can swap the top from a TD pump onto the 1.5 pump...
How about the prechambers? Difference between the 1.5 and 1.6 prechamber volumes that might effect compression?
I read the link thanks. Good stuff in there. Anyone have a pic of a ported head?I'm trying to make up a list for what I'll need to rebuild the bottom end while it's out. Don't want to screw anything up. As far as the top end goes head studs and the metal gasket are a given. With injector pump I'll use the old one and put a turbo top on it. It's going to get tore down and a full rebuild anyways. Probably do the governor too.Vnt-17 turbo and as big of an exhaust I can fit. Should be good!
the difference wasnt the pumps, it was the injectors.. early 1.5 engines had like 180? bar injectors.. thats why they have a 1.15mm timing spec.

The early pumps had a steeper dynamic curve, but I'd not noticed any bars other than 130, but that's not to say it didn't exist though
no, i will find it. ive read somewhere that early 1.5 diesels with "yellow dot" pumps, have an unusually advanced timing spec because of the high breaking pressures. but i do not recall exact numbers at this time. i remember it being higher than the TD breaking pressure tho..Giles Jr or Vincent would know for sure.
