i have another question. how does the eagle b20 conversion kit work cos they say you dont have to drill new dowel holes??

and why do you need a crank girdle? what does it do

The sensor directly to the left of the oil filter is the oil pressure switch,the
hole that you have circled above the oil filter is the hole for the knock sensor.and as far as girdles for the bottom end go as ALLMTR said you do not need one but it does help with strength in the bottom end and stops some of the harmonics that cause sleeve cracking.
