I am starting a 1.6TD build version 2, hoping for more than 40,000 miles :D - page 32 - IDI Engine - VWDiesel.net The IDI, TDI, and mTDI source.

• She does look like a tiny you.
  Smart move on the pre-stretching.

• I feel your pain for the manual rack boots... It took me 4 hours in total to put both sides on

  It took me about that long as I had to cut new threads on the outer tie rod end. I missed with the hammer, but the actual boots went on in under 1/2 hour

• I did some full pedal runs over the holiday weekend. I was messing around close to home if something would break, but it held up. I honestly think now that I have ran it hard with this turbo that it will hold up for a good long while, with this pump. The head and turbo out flow all that this pump has to offer with the 10mm head and the aaz camplate that Giles put in. I still get some black smoke at full pedal, but the EGT are staying under 1,000F and this was on a 78f day. All in all I am happy with it now, finally....but I do have an 11mm rover pump in the basement

• You would even be able to empty a fully built 11mm pump with that turbo, so just go ahead and do it

  I like being able to use up what I have, but I also want this one to stay together. FWIW I believe that the older CY block is a ton tougher than the newer MF block I used to have. I have no evidence other than when drilling the head gasket holes with the exact same size, brand, and new bit the MF engine went in like butter, the CY took a long time. I still worry about the engine not holding together with all the pressures against it.

• The head work you did sounds like it's the ticket. Also, your turbo is a bit larger than my HE200. I can still hit 1300 on a long hard climb or getting on the freeway. I'm possibly a ton over your vehicle weight as well.
  Congratulations on what seems to be a solid build - I'll bet it scoots!

• More boost gives a higher AFR ratio and lower EGT so more boost can actually be a good thing

  It will only boost to about 30 psi and comes down to 25psi if I stay in it hard. I think I don't have enough fuel for the flow of the head to do any more. I don't know if I could get any more out of the MBC either, but I don't hear the WG opening, so I think that isn't the limiting factor.
  
  Yeah the boost is great. I built this engine to combat the high EGT of the last one and succeeded in every way. If it is flat and I just have to maintain speed of 55mph my EGT is around 400f with 1-2psi of boost. Full on the egt stay under 1000f. Even the oil temps stay cool rarely over 200f and the coolant is staying around 180f... I have the coolest T stat you can buy for these and the custom radiator that holds an extra gallon of coolant. I think the only way this one is coming undone is from all the cyl. pressure and the flex that all that entails.
  
  BTW Alcaid, do you have another one of these turbos you could get me at the same price I think I will be selling the big VNT I have for my jeep project if you do.

• Unfortunately the HE221W version you have has become unobtanium... The HE200WG is very close anyway with the exact same turbine wheel and also 5cm housing but different downpipe flange. Only cast compressor wheel though comparee to the billet you have now and slightly lower trim.
  
  Remember turbos give you 20% more hp on a TDI vs. an IDI
• #475 by theman53 on 29 May, 2014 08:35
• Is the HE200WG the same as the HE211? Honestly as fast as this one I have spools I wouldn't be afraid of a larger turbo for this IDI and sticking the one I have on the TDI...The biggest feature I like is the ported shroud, does the 200 have that? For that matter I know you can buy billet wheels for 100.00 or so, could the 200 be made into the 221w?

  I don't believe mine (HE200WG) has a ported shroud.

• HE200WG does not have a ported shroud and it will not surge so one is not needed. If surge isn't an issue compressor efficiency will be higher without it so it is actually better to not have it.

  Mine doesn't surge now, but I can tell a difference in the sound of the turbo at low RPM. Almost like if it wasn't ported it would want to surge. Love the little sucker, now I want another

• What engine is in your Jeep and what is the power goal?
  
  I love these Holsets as well, that is why my build has two turbos
