well ended up getting an engineer mate of mine to knock me up a little collar and used that to mount the top feed beige injector. worked a treat and doesnt look too shonky really. took the car out for its first run to try and set the fueling up and iron out any problems, first stop was BP for a tank of their finest then returned to the car and it would start fearing something nightmareish i popped the bonnet to find a vacum hose loose! popped it back on then cracked on. made a few adjustments to the fuel pressure and was having some issues with irratic AFRs, then it dawned on me the ecu would be seeing the AFRs are lower than they should be so was probably trying to lean out the mix to compensate for the extra fuel i was adding by upping the fuel pressure. i disconnected the lambda, after a few runs up and down the road and a few tweaks it seems spot on! more luck that judgement possible but at cruise and low loads the AFRs are sitting around mid-high 12s, gradually dropping as load increases down to low-mid 10s throughout the rev range under full load. quite rich but better to be on the safe side considering the high compression and standard timing - although im guessing now the ecu isnt getting a lambda readout it may have retarded it slightly for safety?! dunno.

either way its running alright, theres a slightly flat spot when under full load as i change up a gear but nothing i cant drive around.

my mate who came with me got this short vid to show the AFRs mainly but i thought id put it up. this was on the first shake down, the exhaust was blowing quite a bit so it sounds like shite, but you get the idea.



im gonna have another play with the fueling and try and lean it out very very slightly for the sake of economy and to try and guard against bore wash. its running less than .5 bar at the minute so nothing major but goes alright. already thinking about what can be done to the inlet side of things to try and help it along a little. and may have a tinker with the dump valve to try and make sure its not bleeding off any boost as its at full boost by just under 3k then doesnt seem to make any more throughout the rev range. any sugestions on that would be welcome, or feedback and ideas in general for that matter!!
