    New Valves?

    Bad results with my SI valves . OEM valves are good

    280 duration cam 0.480" lift vs 0.540" lift

    Did you ever measure piston valve clearance with your combo Leon?

    240Z ITB Install

    OER sells some ITB’s that look like carbs- very nice . They make them in various sizes . As far as programmable EFI - Megasquirt pro might be overkill .

    I don’t know if I’m the one to say the stepper is hard to set up since I am not as systematic as others, but I don’t think it’s user friendly and there are many variables to figure out. Like how many steps is your specific stepper and what’s is the best method of power to use( always on, only moving) , etc... Then the cranking steps , polarity, and just general idle tune to complicate matters. Hopefully I will be posting up a successful tune to help others - after the Richard eye balls my tune to make sure something isn’t crazy. It is nice when it works !

    Maybe- just maybe - I have this IAC in tune . I’m not ready to share yet since I have a few cold starts to do. This has been a ball buster and I should have been more methodical . The AAR valve was looking better all the time. Next week on vacation will be many test runs .

    Another clunk post - ugh

    Checked out the CV’s . For sure there’s probably 5 degrees of slop in the CV just like others said on the 510 site. These issues are hard to compare with others because describing noises doesn’t cut it. For me - the sound is more of a thud then a clunk. There’s no metallic sound . You can feel ,as well as hear the noise in the chassis. If there’s something moving like the diff in the moustache bar I can’t see it while under the car . I do drive my car very hard and slam gears , so it’s possible something is loose or the CV’s are getting more play . Next I will remove nuts from the diff /moustache bar and see if the hole are in good shape. I will check torque before hand. Also going to check gland nuts on struts . Moustache mounting points. Also will confirm that the grease is seeping out off the boots . Like a mist of grease covering the adapters and boots. I do run the straws in the boots for them to breathe .

    Another clunk post - ugh

    2006 STI diff 3:90 gears - clutch type custom made aluminum DS FUTOFAB CV axles new front diff mount RT upper GM style mount It seems to be excessive drivetrain slop causing a clunk based on how the clutch is released. The excess can be seen and felt by hand when rotating DS by hand while in gear. It seems the slop causes the driveline to clunk when engaging torque . Easily duplicated when cruising at low speeds and engaging clutch in a higher gear (4th). I have had someone duplicate this in the garage with front wheels chocked as they let out clutch rapidly in 2 gear and I have watched for any movement - I see none. Harmless slop or diff worn out ? The only other noise I get from the diff is a bit of a chatter when pulling into my garage ( uphill ) at slow speed. I can hammer the gears in WOT and hear nothing .
  9. I think your a little confused on what’s being done here. The valve likes to have room to breathe all the way around the valve. Obviously close to the cylinder wall side is where there’s not much room. So no it’s not ballsy to clearance close to the fire ring if done right. Your exhaust valve side needs work in the green arrow area of your first pic. I’d follow the radius of the valve all the way to the fire ring ( or very close). Make sure you have your head dowels in place holding the HG where it will sit when installed. Do not take any material away from other areas UNLESS you need to adjust your CR by gaining CC’s. That’s probably what Brapp was doing with a small chamber head. Smoothing edges is great but you don’t usually remove much material.
  10. There’s material that could be removed ! Not sure what you were expecting to find but that exhaust could use some work for sure
  11. Okay - I can’t let you slide on this one. you think you had to point out what was exhaust side and what was intake -lol
  12. Did you try moving / adjusting dizzy to different positions while starting ? Maybe timing is pretty far off . Lining up the oil pump has to been done accurately . That 11:25 o’clock position can be tricky to eyeball and it wouldn’t take much to be a tooth off. Double and triple check firing order. Whats it doing when you try and start ? Spitting , coughing , nothing ? Try squirting starter fluid in while cranking ?
  13. Did you align the cam TDC COMPRESSION STROKE!

    Z Car Depot Fast EFI

    I’d help you out but your still 4 hours away , plus I think I forgot how to work on carbs now :0 now if you go Megasquirt I’ll set you up !! Youll need to sell off the Weber’s to pay for EFI , but won’t regret it
