Cheers steve..
The current setup is a built 26 ..forged pistons,stock rods with arp bolts, N1 pump with nitto gears,heavily ported head with JUN 9.5 268 & large valves, ported & ceramic coated stock exhaust manifolds, modified hks 2530's ,R34 dumps, id2000's & haltech platinum pro.
If 2 bar of boost doesnt see it crack 400 then E85 should do it.
It's nothing mega, that one will come later..full counter 2.8 crank,pankl titanium rods & the head from the current one.
