Hi Guys,
im after the coil amplifier pack thing, i have no idea what it is as the engines just been put into my mini so its all new to me but iv been told i need one, theres a few on ebay but they all look different so perhaps someone has one on here!

also need the clamp that goes onto the gear linkage

Any cams.or performance parts im interested in too

thanks a lot

Ben
