200T/220T buying advice

I’m on the lookout for one of the above but I’m looking for a bit advice first. The car will be used on the road and track so won’t be too extreme but also won’t be standard.

Is there any difference in the physical engine spec between the 200 and the 200? I know about the steering, suspension and seats between the 2 but other than 20bhp is there any change in the parts or is it achieved via a remap?

It’d be nice to have the extra power but I’m planning on doing a few engine changes which may mean that this would be achieved anyway with the 200.

Also, is there a difference between the suspension figments on the 2 cars? Are coilovers interchangeable between the 2!
