actual intake manifolds-not air intake
How come no one makes aftermarket upper or lower intake manifolds for GS. How about larger throttle bodies? Are the stock ones just that good?
Just wondering.

Chuck,
Your best bet, and cheapest, would be to have the upper and lower extrude honed. But then you'd need to tune it. I suspect a larger throttle body from a Toyota truck would fit. I have also seen 8 individual throttle bodies on this engine..looks awesome!!

I'd like to see a conversion to individual throttle bodies using the ones from a gsxr bike, since they're 42 mm and would a good size for this engine. I understand that the Toyota injectors fit into these well, and with the superbike crash rate usually high, there's always a set on ebay for sale.
It would help the low rpms too, a needed area for these big valve-engines, should give an overall boost of around 40 hp in a nice way.

I think SplitSecond has a product that would allow for tuning these cars without freaking out the ECU, I've done some stuff with other OBDII cars using their stuff before, no problems/codes.
The Honda guys are catching on to the benefits of individual throttle bodies, and are kind of driving the prices up on the streetbike units.They can pull it of on those cars with a modified oem ECU, fuel pressure regulator, but are most likely using OBDI computers, and not getting a "great" tune I would suspect.
Do you ever wonder if the cars destroyed in the production of "The Dukes of Hazard" contributed to the incredible rise in Charger prices?
