Check out my new exhaust manifold head flanges - page 1 - IDI Engine - VWDiesel.net The IDI, TDI, and mTDI source.

• Note how they go from the stock oval port on one side and than are CNC milled out to the circle size of the primaries.

• Nice!
  
    I also see an almost done intake mani lurking in the background of the last picture!

• Yeah intake manifold is actually a jig piece for when I was playing with runner length to tune the manifolds for the best balance for low end vs. high boost/flow.  You can see the results of my new bead roller on the end of the transition piece there though

• that is amazing...  you keep coming up with more things for me to buy hehehe.... now i gotta save up even more $$$

• is the exhaust piping larger than the round ports?  Just curious if you're gonna have a step to reduce potential back flow (ala Bells 4-stroke performance tuning) or is this not needed in turbo manifolds?

• Awsome work 935racer!!!

• Wowie, that's SICK!  Are these going to be for the D.I.Y.'ers to make their own manifolds?

• wow that *** is looking ***ing sweet, i wish had the dough, i would buy ur manifolds in a heart beat

• Jtanguay, Thanks man, start putting the change in a jar
  
  ezekiel, yes there is a step and its on the oval side of the flange, the circle side for the primaries is perfectly matched.
  
  Benjamin, thanks man
  
  lord_verminaard, Thanks and yes these will absolutey be available for the DIY'er, as well as the intake manifod flange, and different turbo inlet and outlet flanges, and collectors, givin these arent gonna be as cheap as just some off the shelf laser cut vw 8v flanges, but as you can see these arent your ordinary flanges. We have been working really hard to make the best manifolds possible, this flange is just a taste of whats comming
  
  Trevor, thanks mang, start saving that extra skrilla, and you'll get what you want.
  
  Heres a screen shot of my soon to be here intake manifold flanges for 1.6, I don't have a screen shot for the 1.9 version but you get the idea. They will be made from .5" 6061 almuinum.
  
  1.6:
  
  
   I made some narrow angle 4-1 merge collectors for t3 style turbos and vnt style turbos, gt series collectors are on the way. These were all cut on a mill anf fit perfectly, sure as heck can make them much better than this.
  
  Here is the collector I made for a t3 turbo inlet (rectangular inlet/port):
  
  
  
  
  
  
  
  
  
  And the vnt style (circle port/inlet):
  
  
  
  
  
  
  
  
  We made a jig for the collectors for 100% perfect repeatability.

• if you need anyone to test these new manifolds, let me know, i'll do it for the small nominal fee of letting me keep them  :twisted:

• DIY eh? SO I could buy all the pre cut parts and weld it  myself?? Sweet.
  
  Were you ever going to get K24 flanges?
  
  Any Ballpark Ideas of how much money Im going to have to put forth for these....
  
  ...my kids already had a few good Christmases....this will come out of the present fund..

  yessssssss daddy's earned it!!!
  
  this is serious stuff... our engines will operate so much better when each individual port gets exactly the same flow as another... wow i'm so glad that the diesel community is made up of geniuses!!!

• nice stuff

• Metal Porn alert!    I'm drooling right now.  Any plans for a Holset collector?

• Very nice machine work.
