Title: Turbo queries?
Post by: Mr Alford on December 19, 2007, 22:01:16
firstly will a 300tdi turbo bolt straight onto a 200tdi with any performance gain?

can you get uprated turbos for the 200tdi? if so is it an expensive process

so far i have increased the fuelling on mine and cranked the turbo up to 14psi ish

it still feels pretty flat, im gonna replace the glowplugs at the w-end and smash out the cat saturday give the turbo a little more room to breathe  :wink:

If it starts well, forget replacing the glow plugs, they only assist with starting it.... nothing else..... uprated turbo's can be got from Allard, and possible alisport, no doubt other places too, i just don;t know or them....

No as they operate at different Pressures and the oil pump on the 200 is not man enough for it for the 300 turbo but if you want to try then by all means give it a go i am happy to proved wrong

im not that brave was just enquiring for advice, so i wont be doing the glow plugs now as it starts fine every time

what could it be thats slugging it down apart from ma monster tyres?

just had a txt from a friend as ive cranked up the turbo hes gonna wind up the fuel pump as well for me and hopefullly the answer is that i have a clogged cat and when i smash it all out my problems will be solved if anyone knows why its so sluggish please let me know or are the 200tdi's renown for being very sluggish? i can rerely get over 70 on the carriageway and it doesnt like revving over 3 thousand revs is this normal?

Mines a 92 and doesn't have one.... where in the exhaust is it.... 99% of cats are fitted as near as poss to the turbo, to keep the temp as high as possible....

i may have a 300tdi exhaust system then that may be why its such a slug to drive

I didn;t think any 200's had cats, the sure fire way to make sure it's a 200 engine and not a 300, is to look at the belt that runs the steering and alternator, if there are 2 'V' belts, it's a 200, if the belt goes all over the place, and is flat-ish, then it's a 300.....
And if the exhaust ends by the tranfers box, unless it sticks out the side of the truck, i would seriously consider changing it.... there's a good reason the exhaust is supposed to end at the outside/back of the vehicle.....  also, 'If' it is a cat, then thats alsmost certainly why it's slow, after-all, the exhaust is basically blocked!!
Title: Turbo queries?

200's didnt have cats and only the later 300's did

as ron says the 300 has a single belt that runs round all the pullys

one other way to tell is, does it have an EGR valve with metal pipes between Exhaust and Inlet if it does then it is a 300

and it will fail an MOT if the exhaust does not exit the vehicle on the sides, top or back

i would remove the whole thing and fit a stainless system

I'd second the stainless exhaust suggestion - Double S make an excellent one that gets rid of the centre silencer (keeping the back box). It's fairly cheap, well made, sounds lovely and does seem to make the engine a bit more flexible at low revs (don't expect instant Saturn 5 performance, this is more a case of it not bogging down as easily). You will need another pipe to get rid of the cat though.

you can get a cat replacement pipe but i have never had a landy with a cat before

I need one of those - found out last week that I have a cat (didn't think I had one)! Anyone know a good cheap supplier?

answer to all your questions been and looked at the car

i defintely have a 200tdi engine without a doubt as my water pumpo for a start is double the size

altho i have as it seems a 300tdi exhaust system

as for the cat gentle men you do no necesarily have to get a bit of pipe to remove it, i have done this on a few cars in the past, a nice solid metal bar that is longer than the cat and just smash out the honeycomb will take about 5-10 mins quite dusty but good fun and what a difference it makes

If it's got a 300Tdi system on it, then it will be modified....

The downpipe is very different!!!

Also... if you smash up a CAT - I wouldn't be breathing in the fumes!

Exactly what I was thinking - there are all sorts of funny metals in there that probably wouldn't do your lungs any favours! Will have to order one of those from Paddock after Christmas.

Are we not just talking about the flexi-joint here?  I really cant see why anyone would go to the expense of putting a cat on a 200, but they do have flexis same as 300's IIRC.............
Title: Turbo queries?
Post by: Disco-Ron on December 20, 2007, 22:49:12
Mine has no flexi.....
Title: Turbo queries?
Post by: Ja1983 on December 21, 2007, 21:53:07
no cat or flexi here.. i recon someones been swapping bits around, best bet would be to get a 200tdi of similar vintage, and play spot the difference.. but if the wrong exhaust has been fitted, it wont help. id also be looing to replace fuel filter, clean sedimenter, and a general service too. its amazing how much of a difference it can make having a motor running "as it was intended to" rather than "as it does after years of abuse, neglect, and mis guided modification.."

you may also have issues with back pressure due to only having half an exhaust - definatley replace the lot!

why smash cat up???? take it to local scrapyard and they will exchange it for at least £40 and then get new down pipe better job all round
Title: Turbo queries?
Post by: Range Rover Blues on December 23, 2007, 14:03:50
I'd agree, depending on whether it's a factory cat or an aftermarket though, but complete they are worth a few quid.

i turned the diesel pump diaphram up a quarter of a turn, takes 2 minutes to do and makes a noticable difference especially when towing.
