I haven't drifted an RX7, but I did had an RX8 for a couple of weeks
last year, god I loved it, the engine really is superb but it robbed me
of £20 a day to get to work. I am only going on the testimonials of
people? who have converted RX7s to V8, who say that the handling is not
ruined as you would expect. The V8s are not much heavier than a fully
dressed 13B, and being an alloy pushrod engine the weight is still kept
fairly low.
