If that'* the case, I Might as well put a series 3 in it then... I thought they were different.... So what makes them "Series 3" then? if they're Just the same engine???
The S3 don't make any more Horsepower than the S2...... :o

If memory serves, the block is pretty much the same, Series 3 used a metal upper and drive by wire, and will require the series 2 lower/upper to swap over. There may also be some oil pan tweaks too.

Oh pointless then, Not worth trying to use Series 3 engine in a series 2 car.
Thanks.
