I have 2 "pretty good" 1.6 clutches left over from my N/A and Turbo engines. The one in my N/A I was going to run until I realized I maybe making too much power. Pressure plates and discs look fine. I could ship both to you and let you decide :D  PM.

Wow, Smoking Eddie said it took 3 weeks before Prothe sent him his head...  :'(  Looks like I'll be burning gas like a drunken sailor for a while now. Then, it sounds like the new injectors might have issues out of the box. :-(  Hummmm. At least I have 2 sets of new OEM injector heat shields so I can reuse my old injectors if the "new" ones are not good. Time will tell. So, should I pull the head, then just the trans (going to do the clutch now too) ?? Or, just pull it all at once ? :-D 

I've got some time now. Enough I could hot tank the block (Yeah, I'm sold school on that) and swap rings & bearings while I'm waiting for the head and stuff. If I pull the package, I'll be more likely to do the lower end while I'm waiting.

I really don't think the Merc nozzles are a good idea, IMHO...

I'm 90% sure I saw Giles saying they'd be bad mojo with the VW swirl chamber.  From what I understand the Mercedes chamber is a very different size and shape than the VW ones.  Makes sense - an idling IDI Merc sounds a lot different than a VW.  Also I think there's been people who've blown out their prechambers with Merc nozzles.

I think it was Dave (935racer) who ran both stock and merc nozzles on the dyno, and lost ~5hp, IIRC with the merc nozzles.  I see the some of the europeans mention biodiesel nozzles as being better, but I'm not sure which number those are, or what makes tham better.  I believe Giles swears by the stock nozzles, although I do recall seing mention of a GTD nozzle as well.

Yup, from what I've read stock nozzles can flow plenty and it's the right spray pattern.
'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

I'm glad you guys spoke up. I just asked Pete to change my new injectors to stock 1.6L TD injectors.

Arb, you're just the person to build your own injector tester from a bottle jack and replace your own injectors.

FWIW, I get the earlier TD nozzles from autohausaz.com and rebuild them to the *low* end of the pressure spec for best fuel economy.

I use the DNOSD293 nozzles which were spec'd on some vw IDI TD engines and yet are quite inexpensive:

http://sd.autohausaz.com/autohausaz/detailw.jsp?sid=3vjolwfmvksbhdytprkjh155&partner=autohausaz&product=0434250103

After buying the four nozzles you still have to toss in an oil filter just to meet the $50 free shipping.   ;)

Thanks Andrew !  There was nothing wrong with my current injectors that I know of. I only ordered new as I thought, new head, new injectors would not harm anything.

I'll have to search for how to make the tester w/ the bottle jack. Maybe the 12 ton that runs my U-joint press will work for that too.

Bummer, I'm back looking for a head again. Pete (Prothe) just sent me a message he is refunding my $$$ as he is out of stock on the head.

I'm running a set of DNOSD273 "GTD" nozzles in my D24T in my volvo, they came from prothe and I have ahd good luck with them so far.  I also talked to Giles, and he said the stock TD and GTD nozzles both perform well, but the GTD nozzle seemed to make more power in a application with the fuel turned up or with a built pump.  As for economy, I gained a couple mpg after rebuilding my injectors, but i set them a little above the TD specs.  Mine are all around 2400 psi.  I have never heard of building them at the lower end of the spectrum for better economy, but then again I was looking for performance gain.  The extra MPGs were just bonus for me...

I just got Prothe to refund the 4 merc injectors too. when the credits hit, I might drive up to partsplaceinc and get a new Brazilian made loaded new 1.6L hydro head for $600.

When to buy the "new" hydro head from Partsplaceinc and they wanted to charge me another $150 for a "Core deposit" - I questioned whether the head was really new if they needed a core back. He said sure it was new.. I asked what would happen if I brought them a mechanical head back as the core - he said they likely would give me half the $150 :-(  Did not sound very trustworthy to me... so I took a gamble with Prothe - Ordered new hydro head, lifters, valves on a Friday, he shipped on Monday, and 6 days after I ordered the parts were here. His valves are actually made in Taiwan. The head looks to be of good quality. I need to buy a new cam shaft as that's one thing he did not have. Photos to follow.

Many delays in both getting parts and school ending for my son. So, I got the hydro head, hydro lifters, valves, HG, head bolts, clutch disc, throw bearing, and a single injector -   somehow I only ordered 1 injector and  forgot to order the valve stem seals, so another order when out and has been received.. Here's the photos of the parts from Prothe:
 
The head casing and machining look good.


The runners at the valve seat could be a bit better

But the casting roughness is localized at the valve end

The cam bearings look really good.

Machining looks good too:

The hydro lifters were packaged well and felt good.

The injectors were not made in China, but rather Taiwan. Hopefully they will not leak like some of you have found. You can also see the valve stem seal.:


I'm realistically looking at a couple of weeks before I have the engine out and the old head off - I am planning on reusing the springs, spring seats, and clips from the old head...

My Prothe NA injectors have been fine so far. No leaks or other problems. Thanks for posting your report on the head. I've been thinking of ordering one.
