Unfortunately, it's not for the NSX, or even the street. But it is interesting! The new "Aquatrax" R12X has the following turbo engine from the factory:
The specs are 1235cc, 165 HP; inline intercooled turbo 4 cycle 4 cylinder; 11:1 compression ratio.
A quick comparison to the 3.0 NSX motor shows it making ~61% of the horsepower with 2 less cylinders and ~41% of the displacement.
Compared to the 3.2 NSX motor it makes ~56% of the HP with 2 less cylinders and ~38% of the displacement.
A Turbo 3.2 with the same hp\litre output as the R12X (133HP\Litre) would create 427HP at the crank, which is ballpark for what a well tuned moderately boosted intercooled 3 or 3.2 should be capable of.
I guess where I'm going with this is that it doesn't seem that outlandish to squeeze 400+ out of a stock bottom NSX motor of either size. It also makes me feel better to be boosting with stock pistons at 10.2:1 if Honda is boosting 11:1 from the factory. Of course the watercraft has an engine designed for a turbo, but I doubt its got titanium rods etc. However, its not designed to go a quarter million miles either.
It's nice to know that Honda believes in the technology of Turbocharging enough to incorporate it into any production vehicle. Now, wouldn't it be nice if they put them in the 2004 NSX!?
PS-Imagine how kool it would be to have an endless supply of 65 degree water for you intercooler while you race around on the R12X!
Here's what the vehicle looks like:
Its about $10K
