• Gracias por las respuestas.
  Si e calzado el muelle principal. Sera mucho?
  Yo ahora sospecho del filtro del gasoil. sera cambiado.
  No lo culpaba, porque el motor, con la bomba lucas ba bien.
  Pero yo ahora tambien creo que la bosch pasa hambre.
  
  Otra pregunta, e visto que la bosch 2, con mods, hace irregular el motor a 1000rpm, e probado la bomba fuera, y e visto que el  inyector 3, inyecta de menos, mal, lo e cambiado, el 3 por el 2, pero el inyector esta bien. Es la linea de la bomba la que esta mal. E desmontado y el embolo esta perfecto. E desmontado las salidas del cabezal, las veo bien. Las e limpiado bien. Me falta motar todo, y volver a comprobar.
  Saveis cual es el motivo por lo que una salida del cabezal, dar menos salida de gasoil? Inyectores ok
  
  Thanks for the replies.
  If the main spring and footwear. Be much?
  I now suspect the oil filter. be changed.
  Do not blame him, because the engine with lucas pump ba good.
  But I also now think the bosch hungry.
  
  Another question, and seen the bosch 2 with mods, the engine becomes rough at 1000rpm, and tested the pump out, ye seen the injector 3, injected less, evil, and changed, 3 for 2, but the injector is good. Is the line of the pump which is wrong. E disassembled and the plunger is perfect. I disassembled the outputs of the head, the look good. The e cleaned. Motar I lack everything, and recheck.
  Saveis which is why so a header outlet, give less oil output? ok injectors
  
  ROR 2.0, need to sleep more, that you walk after confused and mess up lol
  
  I have now an 8 days and also sleep very little

• Good, I reassembled the large bosch mods.
  
  I think i have found the problem. But still not able to get the car and to try, without battery. . .
  I think the problem of the lack of fuel, due to low pressure in the pump.
  Screw out of fuel, was wearing one of lucas, backstop, but large exit hole. The Bosch is a filter and a much smaller output, I think that the pump does take pressure? right?
  Photos,
  left bosch
  lucas right or otherwise. . .
  
  
  What do you think, is this the culprit of my pump failure?
  That hole is the internal pressure created by the pump?
  Because the fuel inlet is a self-regulating screw no pressure?

• the problem is your primer bulb.. its on the FEED line..
  
  should be on the return line.. when the engine is at anything more than an idle, i guarantee that the vacuum in the fuel line is collapsing your primer bulb.
  
  temporarily take the bulb out, and run the car.. the primer bulb should be fitted to the RETURN line..
  
  i would just about guarantee that is your problem.. my grandpa had a primer in the same spot, caused him MASSIVE HEADACHES until i switched it to the return line, rather than the feed line..

• You can`t change OUT bolts beetwen Bosch and Lucas.
• #19 by akuma406 on 10 Jan, 2013 13:13
• Solved, were the fault of the screws on the photo, the lucas has large hole, and I picked up enough pressure pump.
  Now stretch much, earlier in 5200 to 3rd gear 125kmh, 140kmh now and done. . . I have to be careful not to spend my lap. . .
  
  The other problem, as a 3 pistons at 1000rpm, output fault injection, and had to change the four outputs of the hydraulic head by others, now the engine turns round.
  
  Now I have plenty of fuel available, but a very small turbo, when you have time and money I'll spend the garret t2 a gt1756 or gt20xx or similar, and so have fresh air!
  They say that the ideal is a gt18xx, because it keeps good bass and good pressure.

  im running a GT2056V on my 1.6D, it loves it..
  
  i would think a GT17, or GT18 would both be too small..
  
  i would almost consider going to a GT2256 or GT2260 on an engine that size..

• I do not know, I have no fear that has low car is my daily, and I do not have to reach 2500rpm to have all the power.
  Not a idi, a boy from a 2.0TDI 140cv remap to 180hp, with a gt17xx, said he was told that in your engine, a gt20xx, would not have full momentum until beyond 2400 - 2800rpm, best one gt18xx full boost 1800rpm and 200hp good to keep the wanted, without losing low.
  if not with a mechanical pump idi and fewer low impulse problems, I would have to 1500 - 1900rpm + - 1bar. Can it be? or am very optimistic?
  IDI is also a not ready for strong torque at low rpm, not as aguantasn before turning the cranks. If I change to a turbo gtxxxx, exchange a 2.0HDI rods, which are more resistant t compatible.
  What pressure is your gt2056v to 2000rpm?
  And 4000rpm? or maximum safe

  VNT turbos can spool very early.. thats the beauty of variable nozzle turbos..
  
  mine makes full boost alot sooner than 2400rpm, and thats on a 1.6..
  
  on a 2.0, it will spool even better, and quicker..

• ok, I will try to find a better one or gt22xx gt20xx.
  What pressure are you running, use paddle control mechanic?
  I'm building in arduino mediande electronic control, I have it half done, I only need the pressure sensor 3 or 4bar

  paddle control mechanic?
  
  if you are asking about how i control my vanes, then im using a wastegate actuator..

• have no mechanical control rods and a lung?
  Just a lung works by pressure?
  A photo?
