are the sensors,knock sensor,camshaft angle sensor etc the same on a non turbo engine to a classic93 turbo engine? also have located the other sensors but having trouble with the knock sensor the one i thought it is,is at the right of the engine(battery side) just to the right of the inlet plenum, and is black,round in shape and looks like having a 10mm bolt going through it bit hard to explain...anyone have a pic of location?..please ;-)
