January 31st, 2014: Finishing up the intake (day 1 of 5)Finally planned to be in town for the weekend and it's time to get this intake done!!
On the TODO list:1. Build and integrate a new Water-Injection nozzle. I have been refusing to up my boost until I get the H2O system back in service.
2. Properly finish the Idle Control Valve circuit of the 3S-GTE throttle body.
3. Get the Air Bypass Valve reconnected so I can increase my off-boost fuel economy.
4. Properly reconnect my Power Brake Booster.
5. Reconnect the valve cover PCV hose. With it disconnected, it 1) leaks oil everywhere, 2) it is seriously stinky, and most importantly 3) the ECU has already metered this air so it
must be re-instated back into the intake for proper fuel mixture.
Let's go!
1. Get'n things ready
2-6. Building another water injection nozzle adapter, following the same design from my old SC14 engine. The idea is that I will weld a nut onto my intake (going to go before the S/C) that is large enough for the diameter of the water injection nozzle to pass through. Then I will make an adapter that both A. the nozzle threads into and B. itself threads into the large nut. Now I can remove the nozzle at any time for servicing, or I could just a bolt into the nut to block it off if it's not needed.
2: The water nozzle I have will pass through a 16mm nut. So I started with this bar stock of aluminum, turned it down in our lathe and tapped it for 16x1.50 metric outer thread.
3: Back on the lathe I bored into the bar stock and tapped it for my water-inj nozzle (standard 1/8" NPT).
4: Cut it off and tapped the other side also to 1/8" NPT for a flared end to connect the system to and I'm done! Here is the system put together.
5: System exploded. The nut will be welded to my intake pipe and then another nut will be used as a jam to tighten it in place.
6: Close up showing inner and outer threads
