hey guys and girls just wondering if anybody has any advice on what to try next
the engine is a silvertop rb20det i recently purchased it from adelaide jap dismantlers and put it into a 93 r32 gtst type m i have.
After getting it all in and hooked up i took it to jaustech automotive to get it started cos im not the most experienced when it comes to timing, and they said they did the timing but when they put it on the dyno it was running really lean and he told me the fuel pum needed to be replaced, so i used an r33 gtst fuel pump from a mate it was in perfect condition of a super low km car and i took it back for another run and this is the result (dyno printout below we couldnt rev it over 3000rpm cos it was leaning out) its the same as the first time.
i have had the injectors and fuel pressure checked and they passed, after these dyno's were done i noticed that the car was running really badly (missing at idle and gutless) a mate said the timing was so far out its not funny and he fixed it but he could only do it by ear, when we took it for a drive it ran like it should do no missing at idle and the power i would expect form a near stock rb20det.
i havent had the time to take it back to a dyno yet but just wondering if bad timing could be the cause of it leaning out on boost?
the only mods this r32 has atm are 3" exhaust, dump and front pipe 3" also, pod filter, fmic and i think thats it off the top of my head??
cheers for the help
