if your using the stock feed line as the new return make sure you add some hose to the end of the nipple so the waterfall doesn't aerate the fuel and cause pressure fluctuations....run the hose down by the sock but not blasting it just like it was ran stock!

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Good call, I remember reading that could be the case. I'm using the stock return line for now though, so I should be good.

While waiting on some parts, I'm going to swap in a 6th gen ICU to gain a "door open / lights on" chime and the wiper/washer function. I'm going to replace the electrolytic capacitor on the board and while I'm soldering, I'm going to replace the electrolytic capacitors on my tachometer board as well, because it's not reading correctly.

I am using an Edelbrock Performer X (D16z6) on my setup and did kept some plugs on the underside. However, I didn't use any "Tee"s for vacuum because I don't like the look of them. All vacuum lines are individual, from component to the I/M.

As for your upgraded fuel pump setup, did you use a relay and larger power/ground wires? I'm currently using 10AWG and connected it to the distribution power block (Streetwires).

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

For now I'm just going to run the OEM Z6 manifold, and may consider upgrading sometime later if I feel like it's holding me back. Trying to keep project scope creep to a minimum here. :) Next on the list of purchases is the turbo kit, heat wraps, turbo blanket, fire sleeve, and a tuning session. There may be some incidentals sprinkled throughout that, but hopefully nothing as big as a manifold.

For the fuel pump, yes, I ended up buying the Burton-Racing fuel pump harness. I'll be running the power into the harness directly from the battery positive.

I did end up going ahead and pulling the trigger on an OEM oil pump to get that leaking Melling unit out of there. I also bought an OEM oil pan gasket, and some of this to fill back up with:

Good choice of oil :thumbup: I switched from Mobil 0w-40 to this and there is a noticeable reduction in chatter from the valve train. Holds about the same oil pressure.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

I'll be changing to VR1 from Rotella Gas Truck 5W-30. Speaking of oil pressure, how low is too low at idle? I know bearing clearances and oil viscosity dictate everything, but I'm just looking for generalities. With my current oil, when I first crank my car and let it warm up, I may see oil pressures up above 80 psi, especially once I start driving it (not beating on it) before it's fully warmed up. Cruising pressures are ~60 psi. Once it's warmed up well past the coolant coming up to temperature, cruising oil pressure is ~40 psi, and sitting at a red light with lights and AC on (heavy load at idle), oil pressure may drop to ~8 psi. My dummy light isn't coming on with the pressure this low. It has flickered on once in a blue moon if the AC compressor kicks on at idle and the engine speed bogs, but it recovers almost instantly and/or a blip of the throttle brings pressure back up. I've currently got my oil pressure gauge set to flash red below 10 psi, just to warn me. I'm not turbocharged yet...don't know if that factors into the equation or not.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Turbocharging should have little to no effect on oil pressure if running a properly sized restrictor and water cooled turbo. It is, however, providing an additional pressure relief but should not be that noticeable, maybe a couple psi difference? If you are overheating the oil with the turbo, that changes things a bit. This is why I've typically run a little thicker weight in my oil-cooled only JB turbo cars.

That said, 8psi seems low, have you checked with a different gauge to be sure that is accurate? I haven't seen less than around 15-20psi at hot idle even with an oil cooled JB turbo.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Nope, haven't tried a different gauge but this one is BNIB purchased from AutoMeter. I guess it's not impossible - maybe my idle is set too low? I'm curious to see how switching from 5W-30 to 10W-30 affect it. It also may be something with the Melling oil pump that's in there now - like I said I'll be switching to an OEM pump (not shimmed or ported) in the next month or so. Once I get the fuel updates all buttoned up and the car is running again, I may make a video and post it.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Electronic oil pressure gauges are not the most accurate. Some may disagree. I would do a mechanical gauge reading to compare to your current readings before going any further with your build. 8 psi at idle is low.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Yeah, I'll be looking into it before I get the turbo on there.

I got my Amazon square wave generator in the mail yesterday and it seems to work for testing the tachometer. I'm hoping this evening I can replace the capacitors in the tachometer and in the ICU and get both of those working and installed. My battery tray / fuel filter mount should be back today too, so I hope to finish upgrading fuel components and have the car back on the road this weekend.

Oh damn.. Some weird science stuff going on here!! Excellent!

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Maybe even 10/40. I'd have to look back on your clearances but sounds like your oil may be running a touch thin.. I'm looking around myself for straight 40 or 50w, especially since summer is coming up. Found some VR1 50W readily available nearby, and not bad pricewise.. 7.99/Q.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

5-30 seems like it would be too thin for our area. I was told stay 10-30 or possible thicker

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Nothing beats stock Genuine Honda parts, such as water and oil pumps as well as gaskets. If you change your mind about getting a turbo kit, let me know. My nephew can fab up a downpipe, manifold and W/G dump tube for your setup.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Thanks man, I'll let you know if I change my mind.

I finished up my fuel upgrades this evening - I got the battery tray back from GAW with a bracket added for my fuel filter so I was able to mount the filter and make the last 2 fuel lines. I cranked the car briefly to set base fuel pressure to 43 psi, check for leaks, and verify the ethanol content gauge was working - everything checked out! I also recapp'd my 6th gen Civic ICU and almost finished recapping my tachometer - I accidentally bought a 47 uF capacitor instead of a 0.47 uF capacitor, so I'll have to wait to get the right capacitor to finish up the tach. OEM oil pump showed up today, as well as a new "false floor" for the trunk (not sure what it's called, but the carpeted hinged piece that covers the spare tire). I was surprised this was still available. I'll be replacing the oil pump sometime in the next month or two.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

engine bay is lookin' proper. Do those gram fuel filters come with SS mesh filter??

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Yes they do. I'm using the 20 micron SS filter, but they also carry a 100 micron as well. They state that they are rated for all fuel types.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

gotcha...I recently had to upgrade the stock FF to a E85 compliant one. It wasn't fun. BTW, the fuel pressure gauge is upside down. LOL

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Haha, yep, wasn't sure anyone would notice. I put it upside down so it is easier to read when standing up. Otherwise I would have had to squat way down to read it in the range it will typically be in.

Did you find a stock style E85 filter or convert to a canister style filter?

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

Very clean progress! Really hoping the OEM oil pump helps with your oil pressure issues.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

I'm using the canister style. The filter inside is a SS cartridge, not a mesh screen. 10 Micron with 8AN fitting ends. As for the FPR, mine is mounted directly behind the driver's side motor mount. The "Marshall" gauge hovers over the mount.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

So I've got a question: My ID1000 injectors are the last piece of the fuel system I have left to install. I'd like to go ahead and install these and start using them to verify there are no issues and not be the guy who rolls up to the dyno with a bunch of untested shit. Is it as simple as installing them, changing the injector size in Hondata, and selecting ID1000 from the "injector dead time quick select list"?

Thanks man! Me too. Especially combined with a thicker oil.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

I read this entire thread yesterday. Very interesting and nice work.

Re: DaX's D16Z6 turbocharger build - older, but maybe not any wiser
 

that should get the car back to running with the new injectors, then you can start tuning again
