My S400SX FMW 1.25 AR T4 build:
Should be turning it up to the 600-700 wheel range in the near future, then I will need to work with the fuel system to squeeze a bit more out of it.
2.6L ej257 (79mm stroke, 4" bore), sleeved, o-ringed, cosworth crank, spinning 8800
v7 ej207 heads, cnc'd, ported, polished, +1mm valves, springs, retainers, Kelford 280s
ARP 625 outer studs, 13mm inner studs
Will be running e85 then switching to e98 or ignite red when turning it up.
