depends, is power relative?
my car is only ~135awkw thru an auto, so prob 150-160rwkw in a manual r33
but my old datto had 100ish rwkw from a 35yo(rebuilt) "standard" 1.8, it ran at 72deg all day every day, engine fan, no shroud, re-cored stock radiator from what i could tell, and it was bored/stroked/ported... so you would think with the higher tech stuff it could be kept cooler? just get a vipec and run cycle idle
