    The only difference between a 325i manifold & a 330i one is the size of the throttle body opening, throttle body itself, DISA & air intake pipework/MAF/airbox. It will fit straight on, and with a remap you're looking at some nice gains - certainly way more top end grunt.

    Get the bigger 330i MAF & 330i airbox/intake pipes too for best results.

    So could I just replace my throttle body with a 330ci one and re map it or would I need hoses too?

    Thanks for all the advise. Didn't know about the exhaust being great as is. I'll leave it and go straight for the remap then....I'll let you all know how it goes.....

    Nope... the 330i throttle body will only fit on a 330i manifold. You would also need the 330i DISA, intake pipes, air flow meter & airbox. One part of this alone is useless to you, you need the whole thing. Bolting it into place is a straight swap.

    The idle control valve is the same, so you can reuse your own.

    Don't expect a transformation from a remap - the diesel examples are chalk'n'cheese different to the normally aspirated petrols. It may improve your 325ci, but it won't transform it.

    With the above mods and a remap have you any idea what sort of gains I could expect? Cheers

    Overall I'd say just over 20bhp, to about 215-ish.

    If you don't mind me asking where did you go fo rthe RR? and what gains did you get? (assuming you used the same RR before the remap for a base reading)
