• I'd try and report back...
  
  Camplate will most likely be different.  Whether that's good/bad/indifferent is anybody's guess since it's a totally custom build anyhow!

• I will do, apparently it has an IDI type camplate with higher lift, so it should work alright with the IDI motor, the governor will probably have to be fiddled with as the cummins motors are built for much lower RPM use, but being an uncaged spring design it should be easy to  modify.
  
  I have been looking at clutches, and a little research shows that our 200mm clutches have the same splines as the 200mm aircooled beetle clutches, which opens up a whole world of cheap performance clutches to us.
  
  I am going to get a 4 puck feramic clutch for $70 shipped!(most of that is shipping in fact, bastards wont ship USPS)

• why wouldnt you just run a 210 mm clutch? cause you cant really get any agressive pressure plates for 8v engines from my experience. im running a 200mm clutch in my GTI, and i can tell the difference. i took out a more shot 210mm, and put in a less shot 200mm disk. i totally regret doing it too. im pretty sure my diesel has a 16v 210mm PP, its considerably harder to push the clutch in on that one than any other 8v ive driven. and it grabs like a mother too, for a half worn out clutch that is. so if you are gonna want something thats gonna hold good, i dont really know of a 200mm uprated pressure plate.

• clutchnet.com has just about any combination you want. They will also custom make an idea if they don't have it and if you want to pay for an experiment
• #214 by truckinwagen on 06 Jan, 2010 11:16
• I would like to stay away from a high tension pressure plate, they put more load on the thrust bearing, and with the right clutch they are unnecessary, I am looking at a four puck feramic clutch, which would grab better and hold more power than a bigger clutch and heavy pressure plate.
  
  if I can convince CIP1 that UPS ships ground to Alaska, I can have it for cheap too(only $37 for the clutch disc)
• #215 by truckinwagen on 06 Jan, 2010 11:58
• yes, I will have to see which valve spurts when, not a big deal really.
  
  what I was wondering is that since the camplate is so aggressive, and it has a 12mm pump head, do you think I will have to modify the timing spec?
  not that its a huge deal to do so, but if it will need more advance to run, I would like to just start there to begin with.
  
  and thanks for all the help again,

• thats what I planned on doing, but probably somewhere in the same ballpark as the vw pump right?
  
  I think I will start at 1.00 and see what it does.
• #217 by truckinwagen on 06 Jan, 2010 13:36
• well, just got done arguing with a customer service rep at CIP1.com and they "cant" ship UPS ground, but the clutch still ends up being cheaper shipped than the clutchnet one is before shipping.
  so I think I will be getting a 4 puck clutch made for an aircooled beetle in the next couple days(just need to find $70)

• cool, good to hear.
  
  I will be reporting all of my findings as soon as this thing runs
• #219 by truckinwagen on 07 Jan, 2010 13:05
• well, I swapped the delivery valves for a set of short ones, so I can use the injection lines I have on the car.
  
  unfortunately I don't have a set of turbo lines that have the bend to clear the LDA.
  
  
• #220 by truckinwagen on 07 Jan, 2010 15:42
• thats what I thought, just pull the pump forward and put the belt one tooth over on the pulley to make up for it.
  
  I am heading out to swap the pump in just a few minutes, wish me luck!

• Good luck.
  
  I forget, do you have an EGT gauge?
• #222 by truckinwagen on 08 Jan, 2010 00:32
• I do, but I forgot to put the thermocouple in the manifold when I had it off the motor.
  
  good news! the motor started, but not for long.
  I noticed that there was not oil pressure, so I turned it off and started looking.
  
  turns out that I have a short shaft oil pump, and a vacuum pump designed to drive a long shaft oil pump, so it was not spinning it.
  
  all the oil pumps I have lying around are short shaft, and I don't have another vacuum pump, so I will talk to the local VW shop to see if they have either a long shaft oil pump, or a short shaft vacuum pump.

• I set the pump at .90mm and it fired right up after priming the injection lines.
  sounds really rattly and could probably retard it a bit further, but I haven't been able to drive it around yet, so I will wait until after it is on the road to decide where the timing should sit permanently.

• I'd be a bit worried about EGTs with that pump. It's going to give you lots of low end fuel.
