okay... so I did a search and have came up with the following topics

So I have a few questions
Is putting a 1.9hyd TD head on a 1.6hyd TD bottom end just bolt on (I've always presumed so by the reading)
Do the water/steam holes between the pistons in the head/headgasket NEED to be drilled in the block?
What do people recommend for headgaskets/fasteners? 3 notch? Depends on piston protrusion? and do people NEED headstuds? it would probably be a wise choice at this point huh?
is the smoke as bad as some make it out to be? or is it just a myth. I see Chrissev mentioned in one of his threads that he had really low compression in his cylinders.
I'm sure I'll have more questions as the thread progresses.. I'm curious, I've always heard about doing the frankenmotor... and I just happen to have a lead on a 1.9TD head... and I already have a superpump from giles... I'm thinking about just going ahead and doing it.

Yup I'm perdy sure it is.
-
should be a bolt on, cant say much as to the smoke, etc. as I have never done it.
but I would love to now that I have a hydro lifter motor!
-
yeah i did it just fine.
drilling the extra holes is easy easy.
the only thing is you have to run it super advanced so it will start easy. makes for a rattly engine but its totally fine.
i love my 1.9/1.6
massive torque increase
-
it is literally a bolt on replacement. i dont know what else to say.
you deal with the slightly lower compression by advancing the timing. smokes white for about a minute in the dead of winter.
if you dont have any glow plug problems its not an issue in the slightest.
im slightly surprised you didn't find my thread (http://www.vwdiesel.net/forum/index.php?topic=16482.0)
-
Actually.... I did find your thread.... but it wasn't until the next day I thought about saving and displaying my findings.
But as for the headgasket
Hydraulic Engines:
- 1 notch - 0.66-0.86mm
- 2 notch - 0.87-0.90mm
- 3 notch - 0.91-1.02mm
Do I use the 3 notch?
which ARP bolts (head studs?) do I use?
thanks guys!
-
what is your piston protrusion?
as for the studs, you can go for the ford cosworth ones, or the new TDI specific studs available from ARP.
both part numbers and vendors should be available in the FAQ section.

Here's mine:

Great mod. Don't hesitate.

I'm unsure of my piston protrusion. I intend on buying all 3 headgaskets.... measuring... using the one I need and returning the ones I dont need..
I'll check the FAQ for the studs that I need! Thanks!

I had also found yours as well saurkraut, but I noticed yours is a 1.9td hyd head on a 1.6 mechanical block.... I'm doing hyd->hyd... fortunately enough for me :)
But I did some searching.... and I found the ARP part numbers
251-4701
so I need those....
and the part numbers for the different notch head gaskets....
then comes the tricky part..... :)

My build is a little different, I have a situation similar to saurkrauts, I have a Hydro head and a mech block "no oil return" I plan on using a mech cam and mech lifters. The modification is a little confusing so I'll keep it brief. It is SUGGESTED that you drill the steam holes in the block "I used a AAZ H/G as a template" there is also an overlapping hole in the mech block that needs a solution, but that is only if you are using a mech block. I have decided to use the aaz "metal" H/G so there is some consideration when aligning everything. I will use the mech lifters and cam in my aaz head, so that being said refer to saurkrauts post for part no's etc. I have not personally finished this engine. It is still in the works, with a lot of work to come still. Dry sump, block girdle, custom 17/22 hybrid vnt, pd150 intake, ceramic coated everything, custom headers, lightweight flywheel/crank, arp studs for mains and oil pump, larger oil pump, chromoly h-beam rods, custom ceramic prechambers, and a giles pump, with some personal boost pin mods. I am going for the very fastest frankenmotor that I can, to see just what these engines can really do. Your build doesn't sound near as complicated, but I will be following your build to learn what I can.
Thanks, and Good Luck,
Kevin

Well... I've got my 1.9TD head....
although it's got cracks between the valves, I figure it should be okay. I've seen lots of 1.6 NA's and TD's with those cracks.... so I'll have to have the head pressure tested, and while it's in the machine shop... have the mating surface checked, and a port and polish...
still have to get the head bolts, the head gasket and such... but now that I got the head.. the hard part is out of the way.
-
don't waste good money on a polish won't do you much good
-
I've never seen a 1.9/1.6 engine in real life so I may not know what I am talking about.
If you do have to advance the static timing in order to facilitate cold starts what you could do is add some shims to the advance spring in the pump to shift the timing curve closer to stock. You would have to listen to your engine at different RPMs (under load) to see if it is running to much advance or not.
-
What are your plans for the engine? If you're not boosting like crazy, it's probably a good idea to run a 1 notch head gasket regardless of piston protrusion. That'll keep your compression as high as possible
-

I would still measure your protrusion - if you need a 3 notch, I would not jump to a 1 notch - if you get carbon build up after a while, it might cause problems... just my thoughts.

I've been reading most of these threads and it sounds like an awesome idea for a newer motor. I think I may invest in a 1.9 head, I'm just a bit worried about the smoke. I don't know much about 1.9 two stage injectors, but I read they will fit a frankenmotor. Would these help the smoke issue? I wouldn't be necessarily looking for all out hp as I have a std 1.6 T3, more torque down lower is what interests me.
-
If you want more torque low down you should be swapping bottom ends
-
Well.... it's been 4 years... I FINALLY got off my ass and starting putting this thing together after my injection pump bracket bolts walked out...
yep... motor shook the bolts out... had variable pump timing... LOL, and I think that may have also been part of a few of my issues.... it was so bad I started the car, went to take it down the road, and I guess it jumped time. I took it apart and only noticed one lifter was cracked, but I decided that now was the perfect time.
had a few upgrade parts laying around, went and got a 2nd 1.9 head in better condition... and uh.... ya... just finished slapping it together, timing it, and firing it over tonight...
-
Cool.
-
Can't wait to hear how it works for you.
Mine is a 1.5 bottom end with 1.9 AAZ head. It starts well, but is definitely smoky. That's OK, it's not a daily driver.
I'm not trying to start any arguments, but mine may be the only running 1.5 Frankendiesel in the USA.
167 HP, and I'm very happy with it.

When will you be "the only running 1.5 Frankendiesel in the USA with compound turbocharging"? ;) A 1.5 really needs boost for land speed records!
-
My first chance to run against an official record is in June. That will be at the Ohio Mile, which is a pavement event. As long as I don't blow it up in Ohio, the next event is Speed Week at the Bonneville Salt Flats, in August. Speed Week is the grand-daddy of all land speed racing events.
This year, I'll be running just the single GT2056 Garrett. My credit card cannot stand any additional punishment at this time.
I'm in this for the long term, so there will definitely be future attempts with variations in hardware.
Steve.
-
...something like "keep adding boost until you run out of fuel, then add more fuel, then add more boost, then...."
I would like to install a water injection system before August, and probably before June.
