Hi folks, just got me a 300tdi Defender. Wondered what the sensible moves would be to improve performance, economy etc? From what I've picked up here I should be thinking about removing the EGR valve (parts on order) and de-gunking the manifold, de-catting it (that'll be the next job), but what else would people recommend? Any benefit in forking out for a K&N or Pipercross filter?

If it was pre 92 you couldn't remove the cat either
WTF are you on about anyway?the clue is in the OPs post. Has a 300TDI (you know diesel) so removing the cat isnt a problem as diesels dont get emmissions tested at MOT time.
and just in case your still not sure Land Rover Discovery 300 Tdi de-cat/cat removal pipe on eBay (end time 05-Apr-11 11:27:18 BST) :doh:
neil - this do ya?
every time you touch the brake pedal youre effectivly turning fuel into waste heat.... so look ahead and back off the throttle earlier so you dont use the brakes.
youve got the aerodynamics of a brick... keeping the speed down does improve economy.
harsh acceleration and high engine revs in low gears also wastes fuel ... 2000 revs is usually enough in the lower gears

Small.. Japanese.... Sports... Car??? I don't think so. Performance and economy are obviously relative terms; perhaps what I should've said was "how do I squeeze a few extra mpg out of it, and at the same time go from painfully slow to just plain slow?"
Seriously tho', thanks, all, for the advice, re - both mechanical and driving technique. All duly noted. The exhaust will be getting some attention next weekend. Today I have mostly been taking off the EGR; was horrified at the black carbon crud that had been deposited in the manifold...
