  1. Where do your timing marks line up to, yellow or red? I'm about out of ideas...
  2. Well fire that puppy up, you might have fixed it lol Is your idle control plugged in properly, if thats not opening to keep the motor running, rpm will be down as well as vacuum
  3. Last thing I can think of, my fuel map need adjusting after tightening the valve clearences but it still ran and idled
  4. Did you hold the intake cam on the hex with a spanner while removing/installing the cam gear? If not it might be jammed advanced and could probably cause something like this
  5. Was it running with these cams prior or were they put in while doing the head. Can you put an air fitting in spark plug hole while at tdc comp stroke and listed to see if valves are sealing. Those clearences will not cause it to have no vacuum
  6. What rpm will it run steady while holding throttle open. Are all the vac lines connected properly, might wanna do a leak test
  7. How much vacuum do you have and what cams. I just set clearences to what yours are with type b poncams and mine has 13-14 in vac, still have to set the ecu up properly too so might get a bit more
  8. Nah it was all done by hand with die grinder, just traced the gasket. I didnt take many pics but started by knife edging the divider then slightly open the bowls to same size as the seats, smoothed the radius of the short turn and slightly opened the ports to same size as det head then just blended it out to the marks from the gasket, i dont think id like to see any flow bench results lol. Those are r35gtr coils from prp. Yeah its just a cover from a hydro 25 as i dont like the look of the neo ones, rb20 cam covers on it too. I did weld fittings in the cam covers on the other motor but these ones um i forget..... I think those are the standard nissan ones i cut and welded with -12 fittings, you can get them push in to an but the ones i seen were straight so you had to put a 90 degree hose fitting and they stuck up and i didn't like how it looked, ill take a pic if i remember in the next day or 2
  9. Nah this was full budget this time round i just opened them up with die grinder, no machining done at all. I just cleaned and measured everything, light hone on the block, cleaned everything again, and again, slapped in some valve stem seals and threw it together.
  10. Almost ready to go hurt some feelings, hopefully not mine this time lol
  11. There us usually a oil bypass in the left hole, I removed it and plugged the hole and used det oil cooler warmer thingo
  12. Bottom end assembled Dodgy piston stop to tdc the engine to set cam timing
