Does anyone upgrade larger throttle body?

thanks

 

Before you change any parts and spend a crap load of money in the shop have the ecu reprogrammed and updated. If you have a good relationship with a mini dealer they will probably do it for free. Otherwise I think it’s about $200 to have it done.

 

I just wonder why I have nerver seen R56 upgrades throttle body. Also can’t find it on market.

 

no after market, oddball engine doesnt share anything with larger displacement...you may find a bmw with the same bolt pattern but i doubt they'd be interchangable.
and if you have an n18 the throttle body is only used on cold starts after that it goes wide open and vanos controls idle-wot

 

thank you so much.

 

they make a pretty slick plate for meth injection that mounts right at the throttle body for N-series BMW engines thats the only reason i know they have a similar 4 bolt pattern but never bothered to grab one and see if it does fit

 

sorry I meant to post that to the related thread below. I’m not sure about upgraded throttle body for the r56
