Re an R32 fuel tank, one thing I am considering in a few years time when my car is further down the road of track only is an alloy fuel tank which is only 35L and sits tight to the diff/axle. So effectively cut a std fuel tank in half length wise and limit the mass overhang behind the rear axle. Along with the front suspension change from R32 to R33/34 the fuel tank position is about the other major design improvement. I am trying to convince a friend to give it a go in his R32 track car
The other thing I will am doing is sourcing an R34 PS pump, smaller, lighter then the 4WS hydraulic pump in the R32, only will need to hold off until the 26 crank and harmonic balancer go into my car due to the different belts they use. When I do this I want to go for a banjo bolt and braided installation to a custom PS reservoir. My thinking is that since PS rcks use brake fluid, and track work boils PS fluid, then the custom alloy PS reservoir may as well have water cooling coil in it.Will need to consider the length of coil needed inside the PS reservoir, may be easier to join a few std PS coolers together and throw them up front behind the IC
