Hey fellas just looking for some advice towards the build of my R32 GTR.
So a little bit about the build first.
*Extensive head work ( ported, +1mm valves, Tomei type 'C' springs and retainers, Tomei 280 x 11.50 cams)
*Nitto rods
*Standard block 86.5mm bore, grout filled to bottom of welch plugs
*Standard inlet manifold modified with single throttle body
*Precision 6766 split pulse T4 1.00 AR
*Split pulse manifold with twin Precision wastegates
And all other supporting mods ( nitto oil pump, ARP retainers etc.)
My question is what compression pistons are people using and what is available? I was originally putting a set of arias in that I had ( 8.2/1 I think) But since the local United is now selling E85 I'm more inclined to use higher compression pistons. I know that CP do 9.0/1 and SPS can make anything to order. I was thinking something around the 9.5 to 10 area. Does any company produce these as a shelf item? And also my current fuel system is the stock GTR pump as the lift pump then twin 044s from the surge tank. Obviously going to E85 I'm thinking a lift pump upgrade is in order. What size pump would be suitable for this kind of setup? Any help would be appreciated.
Cheers Simon
