Hello everyone,
I'm from the Netherlands, and to be honest, I'm not an Audi man. My passion is Citroens. Now, you all wonder, what am I doing here. As a citroen man, I do ofcourse have a healthy appreciation for audi technology if not for their thoughts on how suspension should work.
I own a garage specialised in citroens with Hydraulic suspension, especially, the DS, SM, CX and XM. At the risk of insulting audi S2 owners: One of my customers has come to me asking to build a hybrid of an SM and an audi S2. In short, he wants a 5 cylinder 169kw engine and an automatic transmission from an S2 in his SM. I'm here to ask if anyone might be willing to spend a few moments to brainstorm about how this could be achieved. Please note, fifty replies giving me reasons not to or that it can't be done or whatever, which is what I normally get on forums are of little use to me, unless ofcourse you have a suggestion how it can be done better, then I'm all ears.
There are a number of challenges in placing such an engine in an SM. An audi S2 has, front to rear, gearbox then engine, in an SM it's the other way round. That means reversing the differential in the gearbox. I have no idea whether that's possible and that's where I would really appreciate the help of you fellows who have experience with Audi S2 tech.
So, perhaps something a little out of the ordinary, any reactions will be appreciated, and perhaps the problem itself belongs in a different topic.

if it's got a 5 pot turbo in it I think you'll find plenty of interest in it here.
without serious chassis upgrade/ strengthening the s2 engine will tear the Citroen apart , especially if it is going to be front wheel drive . As for the handling and basic geometry it would be totally changed ! Does he have any idea how much more weight he is going to add tom the front end of his Citroen ? Foot down car goes in a straight line , regardless of steering input, fancy Citroen suspension will fail to tame the very torque 230 HP S2 engine. 
on this one
