You can have the stock ones bored out and fit bigger butterflies, I dont know of any aftermarket ones though, the stock ones will support 500+rwkws anyway and i'm sure ive seen some 1000hp GTRs using the stock plenum and ITBs

Yeah, Why do you actually want bigger ones.

Fairy certain HYPERTUNE can do it with their plenums though.

the stock throtle bodies will handle 580rwkw at all 4 wheels (GTR) seen it personally. thats got to be close to 1000 engine HP

Even stock FMIC is easily capable of 400+, probably 580 as you mention assuming it is in good condition

yes, i know it can handle it but its just like porting the head, its good up to like 700/ 800 hp but it will make a better power graph if ported out.
