It is a 6, just a small 6. Its actually the same block as the IS200, 1G just not the FE, but a GTTE. I think 7k is very expensive, id offer 3k, then spend teh rest on a conversion, or as others have said get a JZA70 with the mighty 1JZGTE, or the MA70 Turbo-A which has a modified 7MGTE from factory. Very nice looking cars. The GA IIR is only the slim body, not the wide body like teh otehrs. And im pretty sure the Gearbox in the GA is NOT an R154, but a W series.
