do you guys know if I can use the cosmo fuel pump in place of the stock fc3s S5 fuel pump instead of buying the walbro pump?? Also does anyone have a detailed writeup of converting twins to non-seq on the 13b-re engine?? and a writeup on what wiring needs to be done to the TII harness when running the TII ecu to control the 13b-re?? I ordered the mounts today...I'm ordering the new radiator and fan tomorrow...the engine is on the hoist as I speak ready to convert the twins...I don't know how to pick a upgrade for single turbo, will the cheap ones on ebay work...what do I do just order one that is T4 I'm looking to at 300-325 HP??? I'm putting together a list of sites and post from here for anyone who wants to do this swap in the future...information is all over the place and is not specific at all!!!!
