Hey,

Any one bothered re-mapping there diesel beema?

Got a bloke coming down from celtic tuning friday to up power from 150BHP to 200 and 240LbFt to 320!

Just woundering how much of deference it will make?? anyone got any ideas?

ye i have heared about the turbo problems on these cars. and experienced a bit of trouble in the form of injectors that i had to replace - costing £2500, so dont really want to be replacing my turbo shortly after dishing out that much lol.

have you got one?

I have a 120D. Similar engine, but I do next to no miles in it, and its bog standard. So I don't expect any problems from it (I did have an E46 325i compact at one point however). Im certainly no stranger to modifying and remapping cars though.
If it was my Compact, I would But again, only if it's known to be in good order first. Re Turbo's: I always got the impression that the actual turbo didn't fail, it was more the ancillary parts of the turbo that failed. But BMW being BMW would rather sell you an entire new turbo at great cost, even though some far cheaper and simpler part (like a wastegate valve or whatever) may have cured the problem. Personally, I wouldn't worry about the turbo (plenty of turbo specialists can help out if needed). I'd worry more about the inlet manifold and it's flaps!? Quite nasty if it breaks apparently.. Some owners seem to be replacing them as a precaution. Probably isn't a bad idea, particularly if you intend to tweak the engine.

P,

do you no how much it would cost (ruffly) to replace an inlet manifold?
having just spent all that money on new injectors i would rather not give any more of my hard earned pounds to bm bloody w lol
