R34 Neo Custom Intercooler Piping Size

Sounds like you've already made your mind up

Stock airbox, exhaust manifold, intake manifold and return flow cooler connecting to stock piping locations is good for 300kw and fairly responsive. As stated above, unless your chasing tons of horsepower, there is just minimal gain other than it looking good/neat. For a street car, do all the above and keep it looking stock for law enforcement.

Im getting 290rwkw with the stock intake manifold, R33 TB and custom piping going as close the manifold as possible. Can change the plugs without removing anything. Yes its no where near as pretty, but it looks way more stock. If i painted all my piping black and covered the turbo with some heat shield reckon i could get away with it.
