    I should be picking up my 2003 320D Sport tomorrow, will initially be looking at getting a 'stage 1' to circa 185bhp and 390Nm (common enough numbers) upgrade, having read this thread will certainly look into the swirl flap and breather improvements.

    FYI the 5 speed version of the 320d has the same clutch and flywheel as the 330D (dont know about the 6 speed though) and i have had mine up to 258 bhp with no issues with the clutch. Single engine modification was modified under piston cooling jets internally. It already has forged pistons so no need to upgrade them. Transmission is pretty much the same as the 330d except the ratios, as is the diff. So you have no worries there either. Trouble is people mod high power cars without replacing worn parts and when they break assume that its because too much power has been developed, with the e46 320d that is not the case. If you dont modify under piston oil cooling jets your pistons will melt at around 225bhp. Engine mounts can be upgraded to M3 ones, as can the gearbox mounts. These cars are built really well and can handle a heck load more power than a ford or vauxhaul crap!

    Mods so far..
    High flow injector nozzles (Build myself)
    600 x 400 x 100 FMIC
    Hybrid gt1756 garrat turbo unit (Built myself £275)
    Modified under piston cooling jets (Made myself)
    Power induction pipe with built in EGR blank
    Swirl Flaps removed
    Cat and DPF removed

    This is enough to leave most 300bhp petrol cars (turbo or not) up to around 100mph
    it does 56mpg on a run... and its a touring!

    Having read all this I think all I'll do to my 320D touring is decat, panel filter and remap. Dont want all the power in the world, just a little bit more. 185 would make me happy, especially if I can still get 50+ mpg

    Don't waste your money on a decat and panel filter
    A standard car with just a remap will see 195-200bhp
