i would be looking at your cold start system. sometimes it takes a bit...might be your o2 sensor...at a guess.
looking good buddy, who made the plate to fit the standard throttle body to that plenum?? cause i dont want to get another throttle body lol. as for moving the clutch master i am getting a shortened one (clutch master that is). i am also running an rb25 loom and ecu and rb25 box, i only had to change the yoke on the tail shaft too, whoever says you need a whole new shaft is wrong..
Will put up pics when i am all done.
