I think Toyota should keep tradition alive and keep an I6, the MKIV Supras are only gaining value and if you have one in good condition you can almost sell it for what you paid for it. The MKI-MKIII on the other hand are getting cheaper and cheaper. I don't get why no one really likes the MKIII, it is a very powerful beast and in some ways is better than the MKIV, if people complain that the 7M-GTE can't be as powerful as a 2JZ-GTE, a 1JZ-GTE can always be plopped, may I add fairly easily in to an MA71 body, and can easily produce as much power as one could need.
