Modifying a K20A2 oil pump for K24...

Im building a K24 and looking at the huge oil pump and drive shaft assembly for the balance shafts. Its ugly, its useless and I dont want it. So I pull a RSX oil pump off the shelf and lo and behold it wont fit. So I modify it!!!!
Now with the K20A2 pump (modified internally for better flow) new drive chain and windage tray Im ready to go! Oh and the motor weighs about 9 lbs less BTW. Losing rotating mass is never a bad thing.
