Boost is better.. But what boosts better?

Is 300 with a 1Jz .. and E36 m3 with the S52 (toned down of corse im in the US) or a 93-95 RX7 with the rotor engine.. all nice cars.. and all easily accecible for me at the moment.. and all around the same price.. the question is.. wich one is better? I know each has there perks.. But over all wich is going to be better for sprint/semi drift/drag..? im open to anything you people can pitch, im have a horrible time picking :frown:

The RX7 is going to be the most difficult to own in terms of upkeep but I think would be the better choice for handling. The BMW would probably be the best in terms of overall performance and power. The IS is going to have the most aftermarket support, or at least the same as the BMW with decent handling and power. If I were to pick I think I would take the BMW. With a good turbo setup, they can make some very nice power. But I think the IS might be easier to work on due to its popularity. Do more research and find people with these cars and see what things they have done with them.
