sluggish 200tdi

Get another 4.6 ... ;)

200's and 300's are Turbo happy. Best 300 Tdi I have so far driven had a larger Turbo, all the pipework, intercooler, exhaust, some headwork, slight gearing change (diffs) and had the engine totally rebuilt from sump upwards correctly.

Went extremely smoothly and deceptively quickly. Had about 25% ish extra power and about 35% ish extra torque .. ;)

Sounds like it's in good condition then. :-)

That's true, even without the smiley. My old 200 tdi Disco is in good mechanical order and has very few miles under its belt, but has little performance below about 2000revs. I was up in the Lakes this last X-mas and the thing the surprised me was how poor it was climbing hills unless you kept the thing revved up in a most un-Diesel like fashion.

But it's quite economical, unlike the V6. (so I'm told) What was that phrase that involves eating and cakes?

Having your cake *and* eating it.

My 200 Tdi turbo comes in around 1800 revs so I'm wondering if you have a leaking pipe somewhere between the turbo, intercooler or inlet manifold, that's assuming the alternator has the right size pulley on it but it should be the same as mine which is in a R.R.C. Mine also is a bit lacking if you use too high a gear on hills.

I have had a listen for whistling sounds coming from the pipework area and nothing is obvious, however, a change of pipes may not go a miss.

Mine's also about 1800 revs if the truth be known, I was just rounding things up to keep it simple. The actual 'coming alive' point is a bit subjective with no hard edge as such.

Sounds OK then, exactly the same as mine, bugger all at 1500/1600 then you can feel it come in at 1800 but it performs well otherwise so I don't think there's anything wrong and it's done almost 270k miles now.

Turn the fuel pump up a little, (1.) you need to break off the tamper proof bit on the nut and screw on the back ( bulkhead ) side of the fuel pump. If it smokes you've gone too far so back it off again a bit. Turn it in to increase fuel. It transformed my 200 and improved the fuel economy as the engine wasn't being thrashed to death all the time. ( Disclaimer: There is a very very small chance that this will blow your engine into a million tiny pieces and if it does don't blame me.) TonyB PS you should be getting 35 mpg on a long run, measured properly that is, using 4.54 litres to the gallon not 5.

I know all about people messing with the pump settings, it's just passed it's emission test with a figure of 0.49 when it's allowed 3.00 and it doesn't need any attention beforehand to do that so why f**k about with it? Thanks for the offer but I've been repairing diesels of all sizes for more than 40 years and apart from routine servicing if they're not broke, I don't mend 'em.:-) Oh, and it does 29/33 mpg depending what I'm doing with it.
