2JZ-GE also in the Lexus GS300 and IS300 and the JDM Toyota Aristo.
2JZ-GTE also in the Aristo (actually before the Supra).
1JZ-GTE also in the JDM JZA70 Mk3 Supra.
The Chaser also had two brothers -- the Mark II and the Cresta. The MX83 Cressida is part of the Chaser family.
You should have no trouble finding one of those in the UK, given the propensity of MA70s to rust and of 7M-GTEs to blow head gaskets.
