Ordered a few more bits today to support the higher power build I'm now aiming for. Flex fuel sensor, matched 1000cc injectors, Turbosmart fuel reg and filter, 6 LS2 truck coils and a distributor delete plate. Still deciding on cam, and at any rate, will wait to see what the builder recommends. Got a wee surge tank I'm going to put in; will use an in-tank pump for lifting, with the external pump for high pressure. Will see how I go with the standard fuel hardlines, and if necessary will add a bigger h.p. line and use the existing one for the bypass back to the surge. I don't think there's going to be too much more that I need to do to hit 600rwhp on ethanol, although I may find the limit of the 2.5" intercooler piping before then.
