Its for motocross engines, they don't tend to last very long 
ahh, that makes sense..
i wonder if you can get dimpled valves in a size that fits our diesels?!
That and I bet even in high rev racing conditions the valves probably get gunked up and the dimples fill in a bit. Then it would be like a normal vavle again. Our diesels even more so than the gassers would tend to carbon up a little.

So it's better to have a semi rough intake and a polished exhaust?
I think with my turbo setup and choices ill have problems keeping my head on the block. Has anyone figured out a way to keep these bolted down?
I wouldn't say rough, just not mirror. IIRC 120 grit finish is where mine was at. It isn't smooth, but it isn't rough. The 120 grit surface seems to grab your fingerprint a bit not much, when running across it. 80 I know was too coarse. I will see if I can post a pic of my intake I made as the welds were cleaned up with the same grit as the head.

Beautiful work on that intake.
Did you do the fab & welding yourself?

no. I haven't had much experience with a tig. A guy I have a customer I sell to and he did the welding, but I did all the fab and porting. I guess you could say I built it. I am more of a hammer guy and my tig customer is more of an artist. If you look at my sig there is a 'round 2' and page 2 that explains how it was built. SAUSAGE STUFFERS!!!

run a different turbo that makes less drive pressure..
drive pressure is what kills these, not boost..

Both turbos are pretty efficient and running 44mm wastegates. What's the best way to monitor that pressure?
I'm actually running a 1.8l 8v intake with the ports modified to fit the 1.9 D intake ports. Need to cut off the original tube and weld on something better. I am the active tig welder at the shop I work at. When it's done I'll post some pictures.

if u have that intake with and with proper sized turbo u shouldn't have any issue. just drill and tap a fitting in the exhaust manifold and watch your emp's just like u would watch boost pressure.

yep, i finished mine with 120 grit then the machine shop i had do all the valve work sand blasted all the ports
here is mine u can see i didn't remove much of the hump around the valve guide, i guess i should have judging by how lucas's looks.:
and here is my exhaust manifold tapped for emp gauge, and a coil of copper to help keep the hose from getting hot

1Y manifold is JUST what you need.. already has the D ports, and it is shaped almost identical to the mk2 1.8L intake mani..
no welding required, unless you want to completely remove the EGR accommodations..

Don't know how I missed your "Round 2" build thread before, but I was missing out.
The sausage stuffer tubes look like they worked well for the transition pieces.
I like your idea & need to see how to approach my own intake project. I just bought an ABL intake, I believe from a 1.9 Vanagon. I'm planning to use that as my starting point.

i have a 1y intake and it looks way better than gtd ones...
well i have 1Y all around and when i started the build i was told that they had the 7mm stem valves from stock...

I have more time than money and I would at a machine shop. Making an intake is easy for me. It would be harder to go find a 1Y intake an buy it and ship it. Plus this way it's all custom to what I want.
Side note, got some Alu pulleys made up for my motor at work, do you know the crank bolt hole pattern isn't really a pattern? They aren't in a circle at all and not symmetrical at all. Just kinda weird VW did that.

IIRC, they just offset one hole a few degrees...?

That's good to know. I assume the bolt pattern is indexed like that so the pulley only goes on one way, thus allowing the timing alignment marks to be used.
