G'Day, We're also running the stock fuel system in my brothers girlfriends(yep, thats right!) MA61 with the 7MGTE. Have encountered no probs, also running up to 14psi. We did the conversion ourselves, started first time, runs like a dream. Couple of questions for you guys though, if you can help Were you able to get the digital tacho to work? How accurate is the speedo? If you have an auto, does it behave? Does your cruise work?
Be interested to know how you got around some of these problems. Have not had it on a dyno yet, would be interesting...
