Fuel System upgrades - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

protpibe · 07-11-2014, 11:23 AM

My clutch finally arrived so I'm going to upgrade my fuel system next. I'm currently running the AVO Turbo Kit (Stage whatever). My high map is currently set to 11psi with 94 octane. I would like to run a 15-16psi map, which I'm assuming is the ceiling for the AVO. From what I understand, the stock fuel system isn't up to the task so I'll be upgrading it.

I'm just looking for some feedback on the setup that I'm going with, just to confirm that it will fit the bill.

I'm planning on ordering a DW65c Fuel Pump and 700cc DW Injectors.

Are the injectors overkill, and would the 450's be sufficient? Is there another injector that I should consider? Delicious Tuning is taking care of the tune and they've said that I should go with an EV-14 injector. I live in the middle of Canada so a local tuner is out of the question.

Also, is there any reason that I should not go with the DW fuel pump and go with something like Aeromotive or AEM?

I would appreciate some insight! Thanks

Best solution for in-tank pump setup currently:

Are you continuing with 94 octane? If so, then 700cc injectors are definitely overkill. I also agree that I would probably stay away from the DW65c and go with the Full Blown Walbro kit.

Thanks for that link, it wasn't even on my radar.

And yeah, we don't have E85 up here so it will be 94. It sounds like 450cc would be enough

im at 85% duty cycle with dw700's on e85 at 18psi on my avo kit. the kit is basically maxed so the injector size is good if you are running e85. for 93/94, you wont need that much.

Unfortunately we don't have E85 anywhere, and I doubt we'll be betting it anytime soon. The cost of injectors is low enough that I'll go with 450's for now and if baby jesus ever blesses us with E85, I'll just upgrade.

Thanks for the info guys. I think I'll go with the FBM pump setup
