I have removed the worn out turbo from my Series 2 Land Rover's 300tdi. I have read posts and articles in the past about some people prefering to run them this way in series landies. I have blocked off the oil supply and modified the manifold. But I don't know what to do with the thin pipe that normally connects the FI pump to the turbo. Should I cap it off? Does it affect the timing? It may also be worth mentioning that the exhaust is a tractor style straight through vertical stack. She is not driveable yet, but the engine runs and sounds good.

That needs to be open to atmosphere to allow for changes in pressure if you take it up any significantly large hills. It probably wont affect matters much in the UK though.
 
pressure in this pipe builds up as the turbo spins up and operates a diaphragm to increase the fuel dose. As your binning the turbo, this part of the fuel pump is redundant. I would blank it at the pump but it doesn't really matter.
To make life easy, you can still increase the set fuel dose by adjusting the screw on top of the diaphragm housing ( under the metal cap).
Won't affect timing in anyway.

A recon turbo is £250 delivered. (inc part ex of your old turbo)
 
You really wont be happy with performace without turbo, I'm running 1.9 bar so I know I wouldn't be happy if I lost that!
 
As @K14 says, the boost pipe is entirely redundant without a turbo and won't make any difference blocked off or not other than to keep crud out.

A Di makes quite a suitable lump in a Series imo though you'll miss the turbo if you've driven with.

Biggest downside is noise
 
:eek:
What sort of turbo is that or have you got a boost pin in, tweeked FIP and all that malarki.:)
Standard turbo, no boost pin, pump adjusted in certain areas, timing ring fitted and adjusted, EGT creeps to 700c pre turbo on really long steep hill, normal hills it keeps pulling over 80

What's a timing ring? o_O Like a boost ring?
Sounds like a dragster Landy that! :D
 
Yes, but I think timing ring is better suited as it alters timing not boost, well, maybe boost as result haha

Is that total pressure or boost above atmospheric? If the latter how have you kept the head bolted in place I'm amazed the engine takes that sort of boost.
