SCC interviewed some Mazda people of Japan when driving the RX-8 over the summer...and got some implications of the MSP Miata being released by summer of 04, with a twin turbo KL series V6...also that it would sell for about the cost of a decently equipped RX-8 ($27,500 or so)...I doubt the KL V6 will be used, I don't think it is in any production cars anymore which they pointed out...but one of the Mazda engineers said Mazda of Japan saw a bit of profit potential becuase of a lot of "extra" KL's being made...hopefully these rumors will be sorted out soon...
In Japan the KL-ZE makes over 200bhp NA, with two production turbo's, RWD, and a good production ECU (hopefully) it would be nuts...especially in a 2500lb car...
