Mmmm not really 12mm deep, 17 mm shallow for the turbo base,11mm deep for the new clamp to go on the dp at the turbo a sawzall with a good metal blade or a cut off tool and a pretty good eye to cut your stock exhaust off for the new BD down pipe, Flat blade for the air cleaner,Wrenches to assemble the oil feed line and check valve,19 mm deep to install the oil feed line fitting in the side of the blocl between the filter housing and motor mount on the drivers side,I dont recall what size the oil galley plug is in the side of the block i want to say 17mm.You will get a drivers side dipstick and your going to need a 13mm ratcht wrench or a 13mmdeep well to take the 13mm nuts off that pinch the bracket on the trans dip stick.there is a plastic cover or a plug if you will that covers the drivers side dip stick hole you will need to move this to the passenger side so you can install your new drivers side dip stick(which is a bitch BTW) some teflon paste or teflon tape would be nice for the pipe thread fittings.
