On a 300TDI a different turbo will probably be a waste of money. As to the intercooler - you may get more from ducting air into your current intercooler as opposed to replacing it.

The engine ECU will limit what you get for changes

What air cleaners are you guys running in your 300tdi's???? I want to replace mine. Should I just get a stock one? or some sort of aftermarket Idem? I wish I could pick one up at autozone or something. does anyone have a part # for one?

Stock. George will send you a bulk order of them. I usually just order oil filters and air filters from him in larger quantities.

I'm running a direct replacement K&N filter in the standard filter box in the 90, 110 and Discovery
The K&N has saved the day twice when I've overdone it in the water and got it into the air box, the filter "atomised" it into small enough droplets so that the water didn't hydraulic the engine as they went through. Caused a massive amount of white smoke and loss of power temporarilly though

How often do you change your air filter and fuel filter Dave?

Thanks for that info Mike.

I check the air every time I change the oil (I still do 3K intervals), and I've changed it 3 times in 15K miles although most of that's due to the dust in CO.

Fuel I just did at 15K miles.

You should drain the fuel filter more often than that
I had water in the fuel which got into the injection pump. That turned out to be VERYexpensive .The internal hard facings on pump components rusted (even though they were immersed in diesel). this caused pitting and the compoments ate themselves. First indication of impending disaster was the stop solenoid sticking either on or off, but mostly on, so I had to stall the engine to stop it.{this was caused by swarf from the components collecting around the solenoid. Followed by diesel coming out of the front drain plug on the timing housing, because the front bearing in the pump collapsed due to swarf getting in there too . That basicly spelt the end of the injection pump. A Bosch specialist shop rebuilt the pump for me costing as opposed to for a new pump. They told me that corrosion can set in within 30 minutes of water collecting in the pump internals.
Land Rover don't sell any internal injection pump components separately.
So get draining those fuel filters, 4000 miles of 6 months.

I will check all this crap today when I do my oil change. I also have to drop my oil pan. The seal is leaking so I will be re sealing it today prior to the new oil going in.

Does the air filter match up with any Range Rover Filters? Just curious..

Randy,

If you want to, you can discard the factory set-up on the air filter and run a huge K&N. Thats what I did and saw a little improvement right away. You have to fab a small bracket, but I have a huge airfilter on there now. I didn't like the 3in opening that is the only place that you can pull air from on the original setup. But, if you plan on running a snorkle, I think you have to keep that giant air-box. I have no water here to really worry about.

On your engine pan, if you have not done it, take it off and seal it with rightstuff. Then, when it starts leaking again a few days later, ignore it. The back end of the pan leaks, and I thought there was no way to deal with it, even after replacing the seal 3 times. Then I found out, with the rightstuff, if you leave it alone for 3-5 months, it stops leaking. Good luck.

Don't think so. the filter box is the same for 200tdi discoverys and so the filter is common.
Probably wont help much as all you got were V8's.
K&N's cost around 50 over here for a Tdi one.

Any pics of this set-up?

Changed the oil, fixed the leak so far... Checked the Fuel filter for water and there was not a drop in there even after 4k miles. I guess I have gotten all good fuel. Then I checked the air filter. Holy shit. the thing was packed with dirt and crap. I could not believe it. I ordered a new one. Im sure that will help out my MPG once that is replaced..

VNT for 300tdi?

I was speaking with a buddy with a WRX and he was talking about how people will tune them with various turbos. I can't speak to the accuracy but was curious if you could use the turbo on the hs2.8, its a Garrett GT22. I have been trying to find out which one specifically it is on the 2.8. I know the turbo on the 2.8 has the exhaust and intake on the opposite sides as the standard 300tdi turbo but it doesn't seem impossible to deal with. It just seemed like an interesting concepts, is there any reason why it wouldn't work or more importantly why its not worth doing regardless?

Obviously not


a mate in Oz fitted this 2.8 VGT on his 300Tdi along with a bigger intercooler and air filter and kindly sent me some cool pics and details of the modification...as to the performance,I asked,but the engine has never been run yet,being his RR under "major" mods at the mo...
John (Bush 65 on the PBB) is the man.

Another mate here (Italy) fitted a vgt off an Alfa Romeo to his 200Tdi (Volvo'd),
and says it's basically smoother and progressive...a bit like a NA diesel.
I think it's probably the same feeling you get driving a VW Tdi,like my dad's or sister's.

I think you don't see much Passat or Lupo over there though...


P.S.
IIRC a while ago I asked Pendy on this board (search for a 2.8 Powerstroke thread) about the possibility to do this ,and he suggested not to,it would -can't remember exactly- stress the engine (- reliability).
I presume the bigger intercooler could help here...

Well from reading it looks like the major improvements on the 2.8 were the improved cooling of the engine with work on the block and higher flow heads. If someone were so inclined to do a moderate port and polish on the heads and ran and larger intercooler would it be enough to offset the 2.8 turbo?

Would it be possible to get around the same hp's as a the rover 4.6 V8 from a 2.8 diesel? Or atleast the same hp's from a 4.0 rover V8? What would need to be done to get there if possible?

I think the most important advantage of the 2.8 turbo is the variable geometry port on it. good for low down boost. Don't know about the Hp but you can get some pretty good bottom end torque out of a 2 or 300 tdi just with fuel, boost and intercooler mods.
