Up-grading 300tdi

[davidjmiller]

Hi,

thinking about improving my 300 tdi disco 1. So far I've put on new BFG AT's, the largest size you can without a lift and a diff gaurd (there's another in garage waiting to be fitted). This is what I plan to, in order.....

steering guard, would have gone on today if it was not for the rain
EGR removal
Remove downpipe cat
bigger intercooler
some kind of engine remap?

I'm not into heavy off-roading and I certainly have no plans to go to pay-and-play sites. I want to keep the disco quite road friendly and do some gentle greenlaning, maybe in time some expo's to the Pyrenees or N Africa.

Any comments on the ideas, the order and which intercooler, remap to go for?????

Cheers,

David

a 300 is mechanically controled and you cannot get a remap.
for an egr blanking plate you can cut up the braded hose and weld up one of the ends and use that.
also not meaning to be disrespectfull to the intercooler companies but why dont you jsut got to a breakers and get another 300TDI cooler for £15 and plumb that in aswell.

Bigger ontercooler will allow a tweak on the fuel pump, the extra air allows you to burn more fuel without smoking (the smoke being the limiting factor to how heavily the engine can be tuned when new).

Then that de-catted exhaust and single pipe system will give you more grunt too, making up for bigger tyres.

Other than that, unless you want to get into lifting the thing then some sensible body protection as you've listed.  Sill guards might prove more useful than diff guards, it depends what you're doing.  The towbar will protect the fuel tank for now.

If you decide to lift the thing, budget on the springs and shocks being only half the job.  Longer brake flexis, castor correction, Cardan jointed prop and cranked rear arms tend to follow.  Then perhaps spring location cones (you may choose these plus longer shocks before a lift).

Your choices are limited only by your budget ;)

Have fun.

Boss has raised a valid point here when he said just get another intercooler and plumb that in as well,this is the road i was thinging about because i cant justify the huge amounts of cash they want for an upgraded one,has anyone done this to theres,i would be very interested in any piccys if you have.

[boss]

i will be doing it soon ;) not spending £300 on a bloody cooler! you could probibly get 3 or 4 in the space where the rad is. then just have a friendley chat with the bloke at siliconehoses.com. the formula 3 racing car we had at college had dual stage intercoolers on it they were ones the size of a 300 disco but they worked damn well. all in all if you have to spend £15 on a nother cooler and another £30 on hoses then it is the cheapest/best power increase you can do!

[Budgie]

The cheapest/best increase you can do is to turn the injector pump diaphram 90° clockwise, from the LR standard setting, and put the top back on.
Bags more power, takes 5 minute and costs nothing.  ;)

Adding another standard intercooler into the system may help but you have to watch where it's mounted as you don't want to block the air getting to the radiator. The standard intercoolers are much thicker than the ones built to fit in front of the rad and will reduce the airflow.
I know some have fitted a TD5 intercooler, from a scrappy, and that seems to work quite well.

a 300 is mechanically controled and you cannot get a remap.

Except most of the auto's are fitted with EDC which would be better suited to an upgrade on the ECU?
Not sure but I think tweaking the pump on these is a no-no without causing issues with the electronics.

I think the order you have listed it is best, EGR removal is fairly simple as long it has no detrimental effect with the EDC (assuming it's fitted), remap is waste of money if you upgrade the intercooler afterwards.

Best course of action would be to give the tuning companies a call and have a chat with them, Jeremy Fearn, Allisport, Allard etc. - they'll probably tell you similar things but with different prices  :lol:

Got a standard intercooler for sale (well 2) you can have for a tenner each. For the pipework I woud get some silicone hoses, which arent that expensive.

Has anyone tried fitting twin standard intercoolers to a Disco with air conditioning?

[Steve ray]

Pity you're not in the midlands, I'd have put you in touch with 'Big Stu' at CME (formerly Autopower) at Rugeley and let him 'fettle' it for you  ;)

Has anyone tried fitting twin standard intercoolers to a Disco with air conditioning?

Or even an auto with air conditioning? Where does that leave for the second standard cooler to go?

I know you can get an uprated intercooler with aircon, as Jeremy Fearn quotes for them on his site. What I don't know is whether the extra cost is for a more complex design or the extra man-hours needed to remove the aircon gubbins and refit it after swapping the intercoolers.

A few suppliers do uprated intercoolers for when you have auto and air con....they replace the standard intercooler without any need to touch the air con condenser or the auto oil cooler.  The trouble is they cost getting on for £300, what I was wondering is has anyone fitted a second standard intercooler

The Allard intercooler I have for sale (proivisonally sold) ia designed to be used in a auto 300 with air con. It fits between the chassis rails under the radiator behind the front bumper / valance after the orginal intercooler, so you can buy them aftermarket.

[Disco Matt]

I'm not convinced by intercoolers between the chassis rails - they just seem like trouble waiting to happen.

I have seen another Disco with aircon and bigger intercooler, he'd fitted a Gulf-spec grille and the new intercooler was in front of everything else. Part of the reason I bought the Gulf grille for mine!

Piggybacking a pair of standard intercoolers......

Would you not loose a lot of the pressure from the turbo doing this with all of the extra bends/resistance on the intake?

[Range Rover Blues]

You would if they were in series, but not if they were in parallel.

[Disco Matt]

The obvious trick would be if you could have a radiator specialist build two standard cores into a single unit...
