Need Advice on what injectors to choose

[leeaspin]

Well I looked at my injectors today just out of curiosity because I will be getting my car tuned soon and they are only 550cc....definatly not enough for the power I will be making with my T88.....

So anyways I have never researched injectors before and would like some of your guys input on which ones to go with..I'm probly going to be making roughly around the 6-650 mark on pump plus methanol. I know about duty cycles and everything and will probly be getting some sort of 1000cc but would like some input on brands.

Any help is appreciated!

Try powerhouse racing.... He got my injectors and had a pretty wide range of larger injectors for the rb26. I would get 1000cc for sure and make sure your fuel pump is still working well. Oh ya Braden@jnsimports could help you as well for parts

Let me know!

just in case my fuel pump is stock...what are they rated for?

[Daryl @ RightDrive]

We sell Delphis, they are just over 800cc I believe, and good for your application.
You should definitely upgrade your pump as well, we sell Tomei for pumps.
For Tomei pumps they are rated at 276L/hr whereas stock is 195L/hr if that helps.

Your def going to want to upgrade your fuel pump, and if you don't already get an adjustable fuel pressure regulator.

I know Braden@JNS has these 1000cc injectors i think for a killer price. maybe pm about them

the id1000's and fuel rail combo is what I will buy shortly....as for the pump, which is the best bang for your buck? FPR's are cheap so not worried about that right now lol get the expensive stuff out of the way first!

I've got a set of used Precision Engineering 1000 cc injectors for sale.

I wouldn't ask a stock pump to supply fuel for more than 400 whp. I've got a Bosche 044 in tank pump that has been quite happy to make 525 awhp, but others have gone to much more exotic setups for this more hp. (Swirl pot fed by in-tank pump, additional pump(s) to feed rail.)

For fuel pumps there is alot of great options available in different price ranges, it really just depends if you want a direct PNP or do a little work to make something fit just right!

1 pump to seriously consider if you don't mind custom fitting (sock or pump must be angled) is the Denso TT Supra Pump, it flows 290LPH @ 12V/40PSI or 340LPH @ 14V/40PSI. The kit with sock and installation hardware can be purchased for mid $200s. They are also insanely reliable and handle 600+hp with ease all day long.

Another pump as Dan mentioned above is the Bosch 044, Ben is running one of these and we have sold plenty of them with no complaints. They range in the mid $200s as well with sock.

Then lastly their is the Tomei for the easy PNP option, price is high but no stress and no modifications so if simplicity is your thing then the extra coin might be worth it!

---------

For a regulator I recommend Fuel Labs for the AN ported units. Price is very competitive, they come in many different sizes (as small as 1.50” D x 2.00” W x 2.25” H) which is the exact regulator I am running and they have like 40-50 different color combination's to suit your style!

Hope that helps, let me know if you have any questions!

Thanks for the input so far!

With Bosch fuelpumps it's how they are mounted in fueltank and the sock design? that can cause fuel starvation problems when fueltank is low. I would fit the Denso fuelpump.

Can run a Sard dual entry fuelrail with single return in the middle with Sard FPR and dual Denso fuelpumps in Sard dual fuelpump collector tank in the trunk with stock GTR pump or similar as a lift pump to collector tank. With this setup you can remove the damper FPR, as the fuel coming together in middle of fuel rail acts as a damper. Also no fuel starvation problems on racetrack or motorway when fueltank is low and is quieter due to using intank type of fuelpumps.

Sard collector tanks, etc -

To help eliminate fuel smell that is a well known problem with collector tank setups, use teflon lined braided hose.
