    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.
  5. DuffyMahoney
    I was doing it from my phone?
  6. DuffyMahoney
    Iac balance bar is looking good. Next is having it cut.

    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.

    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

    Numbers are in. She flows well!

    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.
  14. 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.
  15. DuffyMahoney
    I did the same, but i ended up hating the B&M so i went back to stock with fresh bushings.
  16. DuffyMahoney
    Steve Bonk cam, he is a high end cam regrinder.
  17. 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.
  18. DuffyMahoney
    Looks pretty awesome. Nicely done.
  19. DuffyMahoney
    We purge tig weld a lot at work, (I own a brewery) it uses a lot of gas, but welds are amazing.
  20. DuffyMahoney
    Nicely done! I like the head cooling mod and the push to lock a lot.
  21. DuffyMahoney
    I have a brand new hoke trigger for sale. If anyone is looking, for a stock 240z pulley.
  22. DuffyMahoney
    Interesting. If you have the money the zcargarage kit is pretty amazing.
  23. DuffyMahoney
    This might end up being more expensive then the Z Car setup. Which I have. Curious what they will use for the ebrake.
  24. DuffyMahoney
    I did the same thing, works perfectly as my home signal for my EFI system and full sequential. I found a NOS one on ebay.
  25. DuffyMahoney
    Well my stock original 1971 series 1 tach works with my fully sequential r35 coil on plug Efi system (haltech elite 750) . I literally ran the coil positive out from the ecu through the white wire with a red band then out to the coils through tachs white wire with a black band. Nothing else was needed. Added about 15” to my entire positive for the coils. I like how the tach feels and reacts the same as it always has. This would work on any 240z tach and a rb swap or aftermarket Efi with COP and fully sequential. I don’t know if it would work on wasted spark or not. Thanks Dirk Stoop for pushing this way vs the others. Where I got the idea https://www.viczcar.com/…/9515-getting-a-240z-tacho-to-wor…/
