Lexus SC series questions

[Kennedog90c]

Ok I am new here and am hoping someone could help me make some decisions. First I live in Minnesota and I really want a 93-98 Supra but its hard to find any that are in this state much less priced at something affordable. I was also looking at Lexus SC300 and SC400 those are much easier to come by and very affordable. Now my question is what are the pros and cons of the 300 and 400? I know the 300 has the Supra motor in it, can that be easily modified much like the Supra or will it take more time and money because its a Lexus and not the Supra? I have heard that the SC400 has a very very solid motor running strong into the 400,000 mile range but could it be a good performance motor even thought it is a FE motore as opposed to the GE motors? Thats all I can think of right now I need to get going and fix a friends Mercury Sable. Thank you to all who read this and hopefully take some time to share an opinion.
