Hey, all. Looking for recommendations for larger injectors.

Currently the car is running SARD 660's and hitting 100% duty cycle in the cold weather. When warmer, it was mid 90's. I've had to lower the redline to stay safe - bummer... :(

Current setup is HKS2530's @ 17 PSI, Tomei Procams, SARD 660's A'PEXi Power FC & supporting mods. Maxing out the injectors at 498 WHP.

I'd like to gain some head room and thing ~800cc would be fine.

Any recommendations?
Thanks!!!

Thanks. I've got square (EV1) connectors and I believe these are oval, or eliptoidal/ellipse and are physically different.

Not sure of the applications for the two - SARD lists injectors for both square and oval connectors for the RB26. FWIW, I've got a '90 R32.

Hmm, this is something I'm interested in as well. After the Haltech goes in, we're debating whether to go E85 or not. Regardless we're going to be doing injectors and fuel pump.

Would those SARD's ship to USA? Trying to see what the cost in USD will be.

Cool, looks like the low impedance injectors here will work and the prices are great. I'll give them a call.

Went with 750CC's from SMARTFIREINJECTORS.COM. Ebay, but they are from the US and the price makes it worth a go...

Wish me luck! I'll post results when they arrive.

Do your research on your impedance options. Low will normally be harder to tune low end/ idle. High will give you more control.

92 octane, dyno'ed at http://www.carbconn.com outside of Seattle. Maybe 300' elevation. Temps were in the low 60's and it made 520, but then corrected to SAE for the temp it dropped to 498. Surprised the heck out of me too... :)

As for the injectors, I couldn't figure out how to drive high impedance injectors from the FC, so I ended up installing deatschwerks 1000cc drop-in injectors.

Great customer service on the phone and they installed within just a few minutes. After a bit of tweaking the FC on the road, it idles great, runs fantastic around town and the datalogger shows that at WOT at 8K RPM & same boost, at 11.5:1 AFR's duty cycle is at 67%. Much better. :)

Loving the deatschwerks parts. It's really close, but need to set up some dyno time to get everything dialed in to 100% and then start upping the boost. Hopefully early this spring.

Just picked up and dropped in a set of FIC 1120CC injectors. Car is going in for a road tune first and then fine tuning the Haltech on the dyno this weekend.

4 months of down time all coming to a close. Waiting for her to breathe life back again :crazy:

Thanks. I just purchased mine so I'm in the planning phase of doing a light rebuild/refresh. I pick up the car next week sometime. 92 R32.
