Any one know the best way to get increased reliable power from the 200tdi engine?

Thanks Alan

there are various things that you can do, some of them cheaper than others:

- Good service
- Clean out intercooler with thinners (makes a big difference)
- Replace intercooler pipes for silicone pipes
- Check air intake hose hasn't collapsed in on its self
- Fit uprated intercooler
- Tweak the injection pump - Turning up the pre 94 Ram diesel injector pump

Thanks very much ill try the intercooler and servce route first. My wheels have killed what little power it had

So what's the maximum amount of power one could hope to get a out a 200 then? I mean if you were willing to spend on a bigger VNT type turbo, front intercooler, better exhaust manifolds etc etc. What's the most anyone here has got out of one?

2.8 version off the shelf-if you want to spend loads or early 300tdi bigger bearings etc.
Are we talking cheap power

Whichever really, lets go for silly amounts of money power.

Well if you were to modify an existing Land Rover engine for more power you could be spending tens of thousands. It'd work out cheaper to buy and fit a powerful engine in the first place. If you were so determined to keep your 200 or 300 TDi though, you could:

- Rebore the cylinders to maximum tolerance
- Fit larger light weight pistons with light weight con rods
- Lighten the flywheel
- Fit a supercharger, or two turbo chargers in tandem
- Fit an extra two valves per cylinder
- Port the head
- Fit a much larger bore straight through exhaust
- Overhaul the fueling

It'd be totally pointless mind

all sounds to expensive for me, is the 300 engine a good upgrade for the 200? Or are they EFI if they are that would be far to much hassle right?

Nope, the 200TDi is quicker than the 300TDi out of the factory. Later 300TDis have a fly-by-wire throttle and a few other little electronic fancies, earlier ones didn't. I'd be tempted to give it a good service before you start tampering with anything else. You might be surprised at how much poke you can get back.

ok thanks just a full service and intercooler clean out, looks like a few of the turbo pipes could do with replacing ill do this at the same time.

Get yourself a basic Twisted performance Force four package which has a performance air filter, silicon pipes, stainless steel pipes and a paper on how to tweak the fuel pump to get an increase of 15 bhp. Also do clean out the intercooler.

chuck a cup of petrol in the fuel tank now and then...

Proceed as follows.
Stage one is to increase the turbo pressure ...you must shorten the waste gate rod by about 6 mm to raise the turbo pressure to 16 psi..easy on a 200 pig on a 300 ...mind you dont loose the circlip and loosen the locking nut first ...make a length of 1/2 in bar with a slot in the end to push the rod back into place ...essential on a 300. Use a gauge to measure the pressure ...T piece in pipe to injection pump...fuel pressure gauge is often the cheapest to buy ...plastic screen washer T is OK. ( the above adjustment alone will give no increase in performance)

Stage 2

remove the four screws from the power valve on top of the pump ( squarish plate with brass cover in centre ..big screwdriver very tight) The top of the plate will spring up...notice how far it rises on top of the spring.(say 7mm) Remove the cover. Then you will see a black diaphragm..if you want with tippex mark its positon relative to the casing and then remove the diaphragm (lift edges and pull up) remove the spring underneath (do not move the trottle when the diaphragm is out !!) at the bottom of the cavitly you will see a toothed wheel. You need to screw this down to reduce the lift in the top plate to about 3mm ( 7 - 4 =3 ) Wind it down with the edge of a screwdriver and then re fit everything to check the lift ..rarely I have had to remove the ali wheel and grind some off the bottom to get it to go down enough. Now examine the shaft on the diaphragm ...you will see an off centre cut out at the bottom ...re fit the diaphragm with the deepest part of the cut out towards the rear of the vehicle...this gives you max fuel. dont forget the sping and check you still have some lift in the top plate as you screw it down...thats it done .....If you do have some smoke then you have two choices ...increase the turbo pressure or reduce the fuel a little by rotating the diaphragm a little clock or anticloc it dont matter... I have rarely found this the case ...no need to re adjust for the MOT all mine had very low c02 and passed easy....
I do not advise adjusting the screw under the brass cap or the main fuel adjuster at the rear ...you may get a tiney bit more but when you get smoke its a pain to know what to adjust ..adjust only the three items mentioned ...turbo pressure...diaphragm rotation and spring pressure

see you know how to cut n paste
