What Injectors To Use On Your NA VQ35 or VQ37 - AdminTuning Injector Testing & Tuning

In this video I dyno test some injectors we are bringing to market on a local bolt-on 370Z. This video is intended for naturally aspirated VQ engines and shows some of our data and results from the injectors we will be using to support our client base.
This will help ensure people get quality injectors and do not have to rely on the used market of OEM R35 injectors as well as dodge the rebranded and overpriced AliExpress fake Denso injectors that are out there.

Could any one help find a fuel injectors that 800-900cc for VQ40DE, and a fuel rail, I’ve been searching and coming out empty handed

[@nilnine1231]

@admintuning You made a video about using the IDX injectors for the 370z for the spray pattern but mention this would not be a gain on a HR motor. Is that the same case here? Im about to make a push for a 3.7L Short block and some cams but I want to get the fuel system squared away first. I currently have a walbro 255 and Stock HR injectors, Tomei, ISR long tubes, Vstack Z1 intakes, 370s ported and polished mani/plenum and Ported stock TBs. My goal is to get the fuel system squared, get Retuned by you again and build a set of heads and the block over next year.

[@admintuning]

Part of it is the spray pattern, part of it is the ECU. The 1050X work so well on the 370Z because of the ECU itself, whereas an HR using a different ECU with similar intake manifold ports does not give any gain with 1050X over a more standard injector.

[@basedale]

Have you ran it at the quarter mile or compared it to another car to gauge the power? That means you're making 400-420 hp which is E92 M3 territory which would put you into the mid 12's

[@gamesta1499]

Im soon going to purchase the ECUTEK and your tuning for my 2011 G37. I wanted to ask before i upgrade my exhaust, do you recommend two to one or dual exhausts? (Planning to get Race Pipes, Borla Pro XS For mid, to dual piping with 4" Tips. "May add 12" Resignators after Borla on Straight piping out) what do you recommend, thanks 👍🙏🇬🇺

I would not recommend anything Borla. Please use an ARK, GReddy, or Motordyne catback.

[@meggetpangie6199]

@@admintuning thanks for the heads up on that. One more thing, would it be best to stay with a dual or go with a 2 to 1 Exhaust system. Its really humid on my island, averages around 90deg daily. No E85 (Corn fuel) Highest pump Gas is 91.

@@admintuning thx you 🫡🫡

[@Rick_B52]

I feel like those numbers are not the best for the mods / dB levels. I feel like I have definitely seen others in the 340/350 whp range from you guys. Not a dig, just saying I think you're right the motor could be a bit aged.

[@admintuning]

You are not wrong. This combination has done 360+ whp on other 370Zs/G37s.

[@PlutonicGaming1]

Do you recommend e85 on an N/A 3.5 HR? Or should I wait until I boost it?

[@johnmartinez4309]

Boost the car that's the best way to max out the car imo

[@yusefkabib2073]

You can do e85 on an N/A HR. A lot of people do. It’s just that you won’t see huge gains just N/A. E85 makes a more pronounced difference with a fi set up
