please can some1 post any differences between the mk3 and mk4 turbos running gear.

not after engine info or box info. but the suspension setup, track setup, roll bars, ect.

im planning to convert a mk1 orion into an rst s1 in apperence(within reason obviously!), and have an efi rst to fit complete with loads of other goodies. ill be needing a full s1 setup to add to the car, but as s2 is more readily available ill want to know what i could use from the s2 if anything.

also any detailed pics underneath a s1 n s2 would be great!

cheers
