  • What if I delete the EGR, AAC, and Air regulator?

    I know the pros/cons of EGR delete are discussed elsewhere in the forum, but what would happen if I deleted and plugged/blocked off ALL three of those pesky units cluttering up the intake plenum and getting in the way of the plugs and injectors?

    -It all started with the application (a swap into an older datsun) - so I'm using a different rack and pinion (so the z31 rack and PS pump are gone) and the car won't accomodate A/C- hence reducing the need for the AAC

    Other than cold start-up issues, would it really run poorly?

    Also, I note on my donor car, which seemed to run pretty well, that the o2 sensor connector wiring had been traumatically severed - so it's been running with no 02 signal - what has the ECU been doing with the absence of signal? - I definitely plan to repair this, of course, for proper timing/fuel inputs.
    Started with Datsuns and L engines, Mikuni carbs. Now a 1968 Datsun 510: 2200lbs, RWD, IRS, 50:50wt. f/r

    spy a VG30et.. a VG30ET 510?

    Tube frame "done".
    12/10: Interior sheetmetal, firewall done. Fuel + brake plumbing "done". Pulled it all out again to finish the "chassis". Briefly, it drove, then back to the shop.

    Will now attempt an aero underbody - best keep it simple!! I have no windtunnel

    The car will run flawlessly with those idle controls removed. A lot of people here are doing it. Without your o2 sensor your Z is running rich during idle (absence of entering loop mode)

      did it. love it. set your idle with the screw under the cables on the throttle body. it really cleans up the engine bay.

      i left my power steering. i can't live without it. and i replaced the stock alternator with a chevy one wire. much cleaner looking under the hood.
