[QUOTE="pollyp, post: 482610, member: 4527"] tday changed the oil to halfords motorsport 5w50. it may not have worked on the forged engine due to the honing but this stock engine might be ok. walbro pump kit arrived. noticed it doesn't come with a wiring plug :( rang rallynuts bout it and guy says he'll see if he can send me a spare [ATTACH=full]35563[/ATTACH] [ATTACH=full]35557[/ATTACH] [ATTACH=full]35554[/ATTACH] its only 3/4 the size of the stock or gts-t pump so the rubber mounts don't work [ATTACH=full]35553[/ATTACH] tried wrapping a sheet of rubber mat round it but was abit too thick [ATTACH=full]35555[/ATTACH] using smaller patches of rubber was too unsecure [ATTACH=full]35562[/ATTACH] using thin rings of the rubber allowed the clip to be secured but the rubber just slips loose [ATTACH=full]35556[/ATTACH] [ATTACH=full]35558[/ATTACH] so used the large sheet of rubber to surround the motor but squeezed in the plastic casing with zipties so the locking clips are straight [ATTACH=full]26991[/ATTACH] [ATTACH=full]35561[/ATTACH] ain't gonna wait for rallynut to maybe send the plug so i figured i could use normal blade connectors on the motor terminals [ATTACH=full]35559[/ATTACH] [ATTACH=full]35552[/ATTACH] fitted [ATTACH=full]35560[/ATTACH] primed the pump. the stock & gts-t motor used to make a quiet steady pitch humm but this walbro motor always starts off at high pitch then gradually drops to a lower pitch as the fuel load flows through it. not loud at all, same as the gts-t, overpowered by the exhaust. initially a large ploom of oily white smoke came out the pipe as i opened the gate, then reduced abit :/ prob just excess. ran her longer and doesn't smoke now. tuned the injectors and fellas, the AFR is back to normal, goes down to 10.5afr at 7k :) so it was the fuel pump [/QUOTE]
