I would keep both stock usually each will only get you one horse power to the wheels. But that’s just from my expierience. Our intake manifold and throttle body, though not at large as the zdx’s are pretty good already.

One last question for you Wrench,
I'm about to make the switch to run E85. DW 800cc injectors, DW65c Fuel Pump, and Flex Fuel Tune.
From what I can tell you've been running it in your RDX? Any issues you have encountered I need to be concerned about?

If you didn’t already buy the injectors and fuel pump ⛽️. I would go with the dw 1000cc injectors and dw 300c fuel pump ⛽️ for the e85 tune. The dw 800cc injectors and dw 65c fuel pump ⛽️ are recommended for up to 93 octane tune.

I heard about tuning issues that may have been fixed but I’m not sure about that yet...thinking about doing it soon too if those tuning problems got worked out.

It’s been a year this month, but to the best of my recollection, I called them, asked the process, they said just ship the turbo to them with a note inside with info. They’ve built enough at this point where it’s a pretty standard process. 20T billet compressor wheel, high flow 9-blade turbine wheel, and your standard turbo rebuild. Cost at the time was $595 plus $30 shipping. Turn around time is maybe 3-4 weeks? I guess it depends on the season and how busy they are. Just give them a call. Super helpful.
I think Fletcher has a couple already built ones ready to sell, so no down time.

I've read the whole thread and build, I have most of the mods on your list. I was just wondering if you still have the link to your turbo upgrade for the rdx, your build thread has really helped me build my rdx into a monster btw. Thanks for that also.

Chiming in as well to say this build thread has helped me immensely. Thanks to all who have shared information.
I just received and installed my ATLP cat back exhaust, which pairs nicely with the K&N Intake I had done a month or so ago. I've also been running Hondata's optimized tune for the RDX, but haven't had any custom tuning done yet.
My one question, that I couldn't seem to figure out from this thread is: If I order an RV-6 hi flow catted downpipe to add to this setup, is it a waste if I don't also upgrade my injectors? Still on the stock 410s, and with just the K&N intake my hondata logs were running about 80% duty at WOT. I haven't datalogged yet with the new exhaust.
I was planning on just the downpipe for my next mod, but I have points and a coupon with Heeltoe, so I'd rather use that to grab both if the injectors and fuel pump are really needed to fully take advantage of the increased flow and power gains from the downpipe.

You’ve already seen the issues RDXs run into with the stock fueling limits. No need to risk it further. I did mine in two stages: CP-E intake, ETS intercooler, ATLP exhaust, street tuned. Then Blouch turbo upgrade, RV6 downpipe, DW plug and play 800s and a DW 340lph pump, dyno and street tuned.
I’ve since added a J35 throttle body, ported intake, and heat shield gasket, but that was more for building boost off the line than anything else. In hindsight I should have went with 1000s for E85, but the DW 800s were plug and play and that was really appealing without wiring or jumper harnesses. On paper I should be good for around 85% duty on E85 and 400 crank, but that’s not leaving a lot of wiggle room and seeing what these have made on corn, I may run out of fuel before turbo.
Just some things to consider before you commit.

Also, which heatshield and ported intake did you use?
I did end up datalogging with my current setup, and Flashpro is showing my stock injectors at around 90% duty under WOT. I've heard the stock injectors can safely run near 100% duty, but aftermarket injectors can't, not sure how true this is.
Thanks for your insight.

Actually I'm not familiar with those, could you elaborate or link me a thread?

Hondata heat shield gasket, stock intake manifold, but port matched to the J35 throttle body and cleaned up the inlet ports a bit. Nothing fancy. Builds 6-7psi now instead of 2-3psi while foot braking it with the factory safety switch.
There isn’t really a difference between “stock” and “aftermarket” injectors. They’re all made by other companies. Denso makes the “stock” injectors. DW uses a Bosch injector. I wouldn’t trust a tuner that would let you out the door with really anything over about 85% duty cycle on any injector under WOT. Injector failure is a real thing.

Anyone know which 1000cc injectors fit? Can't seem to find DW 1000cc injectors and on HeelToe it seems like the 800cc were replaced with 750cc. I wouldn't mind going with the smaller injector but I wanted to leave the door open for possibly doing E85 in the future.
Also, fuel pump would either be the 65C or the 300C.
Any suggestions?

Follow up to the above post ^ anyone have any experience with the 750cc injectors? There's a note on heeltoe about needing custom splicing on the clips that I don't remember seeing for the 800cc injectors.

If you want to run E85, might as well get the 300C. No downside. No price difference. Always good to have room.
