hey guys ive just upgraded my turbo to a gtx3582 on my auto fg xr6t but the guys at mtq stuffed up the gate mod and boost cant be controlled below 18psi and 18psi is way to much for the stock fuel system so im going to go a plasmaman surge with twin 044s or walbro 460's ready for e85 when it come to townsville but the cam chain guides are worn out so while ive got it apart I wanna do the oil pump and a nice set of cams ive gotta few questions is it worth it going for twin pumps ive hurd ill have to change the fuel reg if I go the twin pumps should I go the fuel rail as well I plan on running e85 and whats the biggest cams I can run with the auto and stock converter do I need to change the intire oil pump housing and or just the gears short term plans are to run 19-21 psi on 98 fuel and around the 400-420kw mark with a mid to high 10sec 1/4mile
