I'm looking for some info on the above mentioned engines.  I'll just go out and say it lol.  Are both engines equally turbo friendly or are there major differences like in the 1.6na vs. the 1.6td.  If there are differences I would love to have some info.  Any help is appreciated, because I might have a line on one with a freshly rebuilt head and only a few hours away hehe.  I hope to hear from you soon.

Hey thats good news.  Would you happen to know if the manifolds from a 1.6td will fit a 1.9?  Also how about the injection pump from a 1.6?  OH and I got one more.  Will the oil pan from a 1.6 fit?  It would be so much easier to get 1.6 parts for this thing instead of importing from canada.  I hope to hear from you soon.

I'm not quite sure what it came in.  I just found a guy who pulled one out of a rabbit.

Everything diesel from 1993 onwards that wasn't turbo.  Now I hear they have a 2.0 diesel.  The original 1.9s had this problem with their crank pulley bolt...resulted in a lot of wrecked cylinder heads.  I guess you know the story.  This was fixed on the later engines.  If you get an early one, make sure it has been retrofitted.

No.  The NA 1.6 is missing some parts.  It doesn't have the oil squirters under the pistons for one thing.  There are some differences in the cylinder head.  You also need to get an oil cooler from a turbo engine as the NA doesn't have one and it is necessary for cooling the oil that goes to the turbo.

hes asking about the 1.9l engines, and yes they are both turbo friendly, the blocks are even stamped 1.9D/TD or something like that on the back. The 1.6l intake manifold is not a direct bolt on 1.9s have larger D -shaped ports. The exhaust manifold will bolt up with its matching turbo, but you may need to find or make/modify a turbo return line to match the turbo oil outlet to the 1.9s in-block oil return. Nothing too major. Also you probably dont want to use a 1.6 injection pump on a 1.9 its my guess that most if not all of the advantages of this engine over the 1.6 would be lost with a 1.6 pump.

Is fuel flow from the injection pump linear to engine speed? It ideally shouldn't be, but if it is then what would be the disadvantage of just turning up the fuel on the 1.6 pump?

if you have ever seen the camplates in a 1.6 vs. a 1.9 pump the profile is much more agressive on the 1.9 with a longer plunger stroke. I think someone had some pictures of the two on here a while ago. I suppose you could have a 1.6 pump rebuilt with the 1.9 camplate and related parts to the same effect.

the 1.9NA's in USA seem to come from here,  http://www.overlandparts.com/dealerlist.htm
as 1.6 replacements (new engine or long block)

conversion kit available for intake manifold, also includes oil filter housing and crank pulley (~$300)

Rumor has it that VW stopped making them in Jan 04, I have a contact that says he can still get new long blocks for ~$2000, but not complete engines, or short blocks.  Vanmania used to sell them on eBay, but now I see their prices for LB are over $3000  (complete new IDI 1.9TDs, used to be $3200 last year)

Not sure if the 1.9 NA was available in a car in North America.  They are generally used in 'industrial applications'  Pumps, gensets...
their power and performance is ~= to a 1.6TD (at sea level  :wink: )

One description I read recently stated that the injector pump was a adjustable constant-speed unit. If that's true it will not work in a car.
