Fitted my gauges today. Didnt have the right tap for the EGT so had to weld the bung on first so it took longer than i'd hoped.

Took it for a spin and EGT maxed at 550, so ive got plenty of scope to tweak. I mounted the boost gauge in the center dash, where the rear window wiper control normally is, so i cant see it great (didn't that that one through...), but I only seemed to be getting 0.6 - 0.7 bar so might need to find some more boost...

I'd still be looking for delaminated hoses, clogged filters or holes in the boost pipe first though

Filters are all new. It's still on its origional hoses though. Do you think some silicoln ones will help? I might stick a new boost pipe on if I can find some for a reasonable price...

A leaking boost pipe or delaminate intake hose would go a long way towards explaining why your injun is so flat.

Silicon pipes look pretty but any other difference they make is going to be marginal
 
Silicone hoses are slightly more resistant to collapse from the turbo 'pull', but on a tdi and with good condition rubber hoses, they won't make much difference. If you do need to replace hoses, there's no harm in putting some silicone ones in. They make it look like you'll go faster, like stripes on the bonnet!

I don't think there is anything fundamentally wrong with my engine. It's well serviced and the cam belt was done recently. I just think the 200tdi's are weak engines.

I blew a rod out the side of my old engine, when that was running healthy it was sluggish. After i swapped in a new 200 from a doner 90, it ran ex-actually the same.

As you've since posted that yours is making way less boost than it should be, we now know this isn't the case.

They really aren't weak engines and are more than up to the task.

It's old now (1992), and they weren't great when they were new, the 300's were much better.

What makes you think this?

A 300Tdi makes the same power, same torque, same everything. They are largely the same engine too. The 300 is really just a cheaper production variant, under the guise of making it more refined (which it really isn't).

I don't care about speed, its a Land Rover anyway, just want to be able to pull. ATM i cant pull uphill without thrashing it.

Well they are really the same thing.

But they should pull fine, although I don't know exactly what you mean by up hill or at what sort of speeds.

billiam said:
People might disagree, but I think there is a big difference between the 90's and 110's. Same power but the 110's have a lot more steel in the chassis, so if a 90 pulls well, it might not be the same story in the 110.

A 110 does weigh more, but it's not a massive amount. And a Range Rover or Discovery are comparable and they drive more than fine.

I dont think so I have two sat outside my house and can say hand on heart underpowered whether rolling or not.
As for full throttle use once out of town thats pretty much how I drive the pair of them again as said above they are old underpowered engines and need hammering just to get anywhere, that sounds mad/boasting but it doesnt even mean they keep up with modern traffic.

I think people need to accept the next generation of motor always beats the one before.
200/300 even tuned will have a hard time against a td5, tune the td5 and its away, same with td5 against 2.7 v6 and 2.7 v6 against 3.0 v6.

My series 2 was originally a 2.0 litre diesel, now that was scarily underpowered, (Im sure fine somewhere sleepy but down here!} in the end after to many close shaves it got a 200tdi, much better but not the torque making gearbox destroying monster people will try and have others believe.

I've not said anything about comparing the Tdi to newer motors. All I said was they can run perfectly fine and are not underpowered for their intended use. And a tweaked one should run quite well, with more than enough poke.

Also an owner of two Tdi engines, plus some rather more powerful ones too.
 
That's good to know about silicone hoses, I thought they looked a bit expensive, new set of rubbers look in order.

I used to have a 300 and thought it was great, tons better than the 200. Quicker, quieter, smoother. (although, maby the 300 was perfect and my 200 has a few little issues).

[QUOTE="300bhp/ton, post: 3742318, member: 72605"Well they are really the same thing.

I agree, but I don't want you to think I want it to go 100mph or out accelerate a porsch. I'm after torque, not HP (don't read too much into that statment, just trying to explane myself...)
 
Plenty of cheap silicone hose kits on ebay, the cheap coolant ones are just fine as well.
 
Has your 200 always been sluggish, or has it got worse? Do you know what t/box you've got? A popular 'upgrade' was to fit a Disco one, which was good for cruising and top-end, but crap for towing and going up hills!
It's so difficult to know if you're ol' Landy is doing what it can do, a good start is to find another 200tdi 110 and drive that to have something to compare to ( as long as that one is running well, of course! ).
 
A 200 and 300 should drive almost identical from behind the steering wheel. In fact I'm not sure if believe anyone who claimed they could tell the difference based on how they drive.

And stock they should have enough low end grunt to pull 3000kg trailers no problem.

Modded they will pull from nothing. 5th gear at 30mph on a fairly steep hill (road) should be no problem and will probably pull smoothly from just over 20mph in 5th.

A well modded Tdi should have loads of instant grunt and a reasonable turn of speed. Enough to keep something like a mk2 diesel Focus honest from 15mph to around 85mph+
 
I would love to see a modded 200 pull hard from 20/30 in 5th with no smoke.
Im pretty certain the only time a tuned 200 has a clean exhaust is when its on boost and pulling well at higher rpms.
 
Who said anything about no smoke??? It's an old diesel engine with no DPF.... smoke, or some smoke is all part of it.

However this neither detracts from the fact a standard Tdi is more than sufficient for normal road and off road use in a Land Rover, including towing. And that tweaked ones can and do run very well.
 
as 300bhp/ton said, there should be no noticeable difference in power between a 200 and 300tdi.

If anything the 200 is the better engine of the two.

Here is a list of problems that can cause lack of power on a 200tdi.

Split/leaking/ballooning intercooler pipes.
Clogged fuel sedimenter or filter
Clogged/kinked fuel line
Clogged air filter
Fuel line/injector air leak
Clogged/kinked exhaust
Stuck turbo wastegate
Knackered turbo
Knackered lift pump
Split injection pump diaphragm/worn injection pump
Injection pump timing out/wrong (cam belt incorrectly installed)
Tall gearing (oversized mud tyres or disco transfer box)
Tappet clearances
Throttle cable wrongly adjusted
 
I went to change the boost pin on my 300 tdi as it was flat and sluggish and it made faf all difference, turns out the guvnour pin was seized on basically minimum setting. After un-seizing it was a different machine, bags of torque from low down and through the rev range. It would certainly be worth checking on yours.
 
Well, looks like I've got a nice list of jobs to be getting on with before I start playing with the fuel pump, shame i've got so much spraying to do, would love to spend a week working on it.

Theres a hill near me (on road) that I can sit on at 30-35mph in 3rd, change up too 4th, foot to the floor, starts slowing, no turbo, have to drop to 3rd it or it will die. It sounds like this is not normal.

Its been on this farm since 1995 and has hardly had a penny spent on it, so i'm certain its tranny box is standard. In the last few years since i've been using it, i've been trying too make it 'good' again (though it will always be a workhorse).

Thanks for the check list nesponge. Half of the things I know are fine and half I will be checking...

I see how this is going now, if you dent mention it first no one else is allowed to first cars and now smoke, theres a name for people like this!

If you are so adamant that a std 200 can pull top gear from as low as 30mph going uphill (your words), put your money where your mouth is and get a video posted up, of course if thats to much effort to prove a point we will have to take your word for it:rolleyes:

Happy to put money where mouth is. Have done many times. But I don't have a standard Tdi anymore.

Also read back I said MODDED, not standard. :)
 
Well a video of the tuned one will suffice.
Its not like modded make it a tyre shredder.
