what are the main difference between the two motors?

i own a 1993 vr and the motor died a few weeks/months back, got a vn s2 motor in now.

differences ive found are:
Oil dipstick to the side of motor instead of in front
No Cam Sensor

lower compression is one too.

diffrent cams, different head ports, different intake runner length, different compression ratio, different timing case

can't think of any more off the top of my head

ok cheers, will my vr heads (ported and polished) fit onto the vn motor?

if the vn motot is a s1 you will have to use the s1 inlet manifold and bolts that hold the rockers cause they are both different, but they will bolt on.

vr heads will bolt to vn block without a problem..

i thought only the s1 cam was different to the rest
