Hi all,
Just did this mod to my s2 r33 GTS-t.
I pulled everything out to get better access and clean everything up, it was much easier with the crossover pipe, airbox and the cooler piping out of the way.
Before doing this I was having difficulties with the car getting to 10psi. I have an r32 actuator in, but I could only ever get ~9psi showing on my gauge.
So after doing this, I get 10psi all day long. Coincidence, possibly. Fixed something inadvertently, possibly.
But for $5 you can't go wrong, do it.
My only concern is that the 'give' provided by the concertina hose section has now been lost. I feel there is a possibility that engine movement could cause the pipe to loosen off.. but I am happy to wait and see.
