Corona 2.0 litres are:
18rc = SOHC, Reliable but not worth the effort.
18rg = Twincam, Reliable and twin solex's standard.
2s-c = SOHC, Mine didnt last long but other people have had them last a while even drifted with them!
22re = 2.4 litre, EFI, SOHC, They are a very torquey motor but watch out for the timing chain problems.
2sc is out of a ST141.
18r series engines are in RT corona's except RT142 which have the 22re.
Those are the only Corona 2.0/2.4 litres i know of.
St141 and Rt142 can look excactly the same but most St141's have single rectangle lights as Rt142 have inbuilt spot lights near the grille.
People correct me if I'm wrong.
Des :cool:
EDIT: 18r and 22r series engines use a W series box standard and 2s-c uses a Borg warner, Since ke55 use K50/k40 id assume the tail shaft will need some custom work.
