You have to also remember that the current J35 is a SOHC unit and it doesnt feature Honda VTC, or I-VTEC. But if Honda does build another great sportscar it cant be a V6, unless its priced a lot lower.
Ive heard that AHM wants a car in the price range of a Corvette. It would make sense because there is a considerable price/performace gap between the NSX and the S2000. i would say the sticker should range from 45-60k.
As far as a V8, Im not against it. Honda could use the engines ia a variety of cars/trucks/suv's. The V8 could be used for: NSX (DOHC, i-VTEC unit, highly tuned), (rest would be SOH VTEC), option on RL, option on MDX, option on the Ridgeline, and whatever car Honda is supposedly going to build above the RL. It could range in size from 4-4.5 liters. Sounds good to me.
