it would probably be easier to convert a 16v gasser head to accept a TDI injector, than it would be to use a PD/CR head..
why cant we build a PD to run like a detroit diesel? they didnt have an ECU, and had cam-operated injectors.. the injectors on a PD are likely all electronically operated? was such thing as a M-PD?
do you feel that your engine doesnt breathe well enough andrew? have you ported the head yet? a few users on here have had AWESOME increases from a good port job on even a 1.6 head.. the 1.9 head yields better numbers yet..
from a cost stand point, i think that a set of under-cut valves, and a good port job are going to net you a larger increase than an engine combo that may or may not work..
just because the head bolts on, doesnt mean it will work.. i believe they changed the later TDI blocks as well.. remember reading that the later TDI blocks had more oil drains, and more coolant passages as well..
i dont know if the 2 blocks are close enough to work tho..
I have not ported any of my TDI engines. Do they 'breathe well enough'? Sure. Would 4 valves per cylinder increase their ability to breathe well? Absolutely. I do not think starting with a gasser head would make for less work. I am not thinking of mixing and matching heads/blocks. I would use the full CR longblock, bolt on the ALH pump bracket where the high pressure CR pump is, fit a custom intake and injection lines and modify the head/injectors to fit.

And then a standalone vnt?
Standalone electronic VNT control will be completed before putting any serious consideration into an mTDI CR engine.

Hi Andrew,
If you have the technical savvy to build an electronic VNT control, I'll bet you could also design a simple stand-alone electronic fuel injection control system for this engine. I'm not saying it would be anywhere near as refined as a factory ECU, but if your only goal is drivability, fuel efficiency, and emissions that are on par with a mechanical fuel injection pump, I'll bet it wouldn't be too bad.
The time you'd save by buying a Bosch motorsport ECU might be worth it though.
While I enjoy the bells and whistles of a stock eTDI, on a conversion I'd rather run a mechanical pump for the added reliability, easier install and easier tuning.
Libby you ought to check out the injectors for V6 tdi they might work for this. I was reading some uk forum where a guy made a v6 mtdi and looked interesting.
Right on. Thanks for the link. That guy does some crazy stuff.
