    Butterfly’s on the Jenvy don’t seat well enough at full close. Spring sticks. So snapped closed doesn’t close enough. So this iac won’t work.
  2. DuffyMahoney
    Well this bosch and all bosch IACs of this style let a ton of air by when closed. Bosch said roughly 30-35%. Which makes the butterfly's useless at idle. My next iac will be a ford. Which closes all the way and only lets a tiny bit of air by.

    Fully wired. I was able to use the coil wiring and leave original wires intact for my dpo negative trigger and positive.

    Well ITB with IAC and PCV is all in and plumbed. Only thing left is 2 wires and some software changes. Pretty happy with how it all turned out.
  5. DuffyMahoney
    now My decision on iac location. I can use the stock 12v + from the coil and also the coil negative wiring for the iac connected to my haltech. So all my wiring will stay the same.

    If you have the money, the zcar kit is pretty darn amazing. It would take the guess work out of all of it. Designed by brake engineers.

    With a 17" wheel you have lots of options for calipers. Google what others use and you could design your own brackets? A few calipers people use are the brembo sti calipers or the Cadillac sts calipers? Sts seems to be every ones favorite for cost. Then you could use a willwood proportioning valve to get your bias dialed in? Nissan R32 calipers are also popular. Tons of options unless you want to clear a 14 or 15" wheel. I have the Zcargarage which is a stoptech kit that was designed with the automotive engineers, the bias is about perfect. It's expensive, but I think its worth it. I wanted 15" wheels and a parking brake, plus as good of stopping as I can find.

    It’s a Bosch from a bmw

    The iac needs to be 5/8 ID. This Bosch is just biggie then that.

    I got pretty far on the intake. I figured out my basic plan. I also tig welded the old holes and drilled and tapped new ones. So they are centered better. I tapped all existing holes for npt plugs. I also drilled each runner to 9mm. I bought a bspt 1/4 for the stock pcv fitting. Also a 5/8 hose Barb by 3/8 npt brass for the iac. I also had my stacks turned down to fit some cheap filters. Brass or no brass? Tioga- I will use a gasket. Either laser cut paper or silicone stuff.

    ITB with IAC and pcv here I come. Which mount looks better. Stock coil mount or the rubber one? Rubber one looks lower profile.

    Balance bar cap is done.
  13. DuffyMahoney
    I was doing it from my phone?
  14. DuffyMahoney
    Iac balance bar is looking good. Next is having it cut.
  15. DuffyMahoney
    Thanks! I got slightly more. But not a lot. Stroker Diesel crank is back from marine crankshaft! Offset ground to 84.6mm Toyota rod ends 1.8896” Ground main journals to -020” Dynamic balance Ion plasma nitride, straighten and micro polished.
  16. DuffyMahoney
    L Diesel Stroker crank. Extra offset ground for toyota rods. I will have full details tomorrow. I had the work done at marine crank. I think it’s 84.5 stroke

    Starting cam mock up. I’m using the bonk .535 cam.

    Numbers are in. She flows well!
  20. DuffyMahoney
    Datsun Spirit valves are in my E31! Next is flow testing. Thanks for all the help Andrew Kazanis Details: New guides, bronze guide liners, reamed to size, seats cut, three broken studs removed.

    I will make the cap nice looking. Somesort of SK logo. I will keep it simple, but add some flare. The casting is pretty rough, first step is to knock that down. My local engine shop has a huge vibratory polisher. I might try that first.
  22. DuffyMahoney
    My oer/ SK intake plan is going to be perfect. Basically I’m looking for a clean way to do iac and pcv. I will have a plate machined to cap this faux balance bar. Then tap each runner for 1/4 or 3/8. I love the oer/ Sk linkage. The IAC and PCV will be done on the bottom out of sight. This is what the Sk/ oer intake look like under that cap. Casting is a little rough for my personal tastes. I will use a Bosch 0280140551 IAC.
  23. DuffyMahoney
    I did the same, but i ended up hating the B&M so i went back to stock with fresh bushings.
  24. DuffyMahoney
    Steve Bonk cam, he is a high end cam regrinder.
  25. DuffyMahoney
    I am offset grinding a LD28 crank to get me 84.5 stroke. I will use eagle toyota rods and custom pistons from rebello. Then Datsun spirit valves on a ported and polished E31. 88.5 bore on either an F54 or N42 block. I will be going NA with 45s ITB. Bonk cam. Should be fun and I think it will be close to a 3.2L.
