Default Five O Motorsports Injectors

Anybody out there ever used these? http://www.fiveomotorsport.com/

I just ordered a set of 780cc pinks. Their pricing and selection is fantastic and all their injectors are new. Apparently they're modded stock but they still have the caps so all the modding must be internal. $275 for a set of 4 up to 880cc!!

I'm looking forward to trying them and I'll keep everybody posted once I install them. (2-3 weeks min.)

They don't have any side feed injectors in decent sizes.

Luckily I'm running Top Feeds.

I'll take this lack of response to mean that nobody has any experience with these guys?

So, I'm about to take the plunge and buy from this guy. Apparently he's got good reviews with the domestic crowd and the bimmer guys. I did see one mention (a positive one) of his stuff on clubwrx.

BTW if you don't see it listed on his site you can call him or email him and he probably has it (In my case it was JECS/nismo 750cc injectors, sidefeed).

18-month bump

Called Bruce to figure out all the topfeed options he sells for Subarus.

He said the following about his Five-O Injectors:

Their ID1000cc equivalent is the Bosch EV14 1000cc ($330 for 4).
They also sell a 1200cc EV14 ($360 for 4), but that's the biggest EV14 they do before it jumps to NGI2.
Then it goes to the Denso EV6 in 1600cc ($380 for 4) and 2000cc ($460 for 4).
Highest is the Bosch EV14 NGI2 2200cc ($680 for 4). This is equivalent to ID2000s.

*ID1000 and ID2000 are a different brand of Bosch EV14 injectors produced by Injector Dynamics. They generally cost a lot more, and claim a very high level of flow-matching and latency-matching in every set they sell.

Bruce says Subaru Sidefeed and Topfeed wiring connectors are the same Denso Sumitomo, and that he can sell any one of these injectors with the male Denso Sumitomo connector so it's plug and play wiring. That and all o-rings would be included for your application.

This is just what he told me. I am not an authority on the subject, and do not know how well anything will work for anyone.

I asked him about tuning, since I have read of some people generally complaining about five-o injectors. He said he has heard of plenty of people who have run his injectors successfully and he says it's mostly in the competency of the tuner.

I generally recommend customers send any injectors they buy--new or used--to a third party professional to be flow tested and maybe cleaned as well if applicable. It is a great way to catch any existing mechanical issues and variance, or just add peace of mind.

Keep us updated with feedback on these. I am about to pull the trigger on a set because I'm sick of waiting for the supposed DW's.

I just bought and installed a set of 1000cc top feed's on my version 8 motor. For the price I got them for (4-1000cc 271 bucks shipped) you can't beat them.

I don't know if it's just the V8 motor's fuel rails but they were kind of a pain in the ass to install. I have to remove the fuel rails and shave down the little hump that keeps the injector and clip in place so the clip would fit.

I couldn't get the DS rear one to fit under the fuel rail so I had to turn it a little so it would clip in place.

I'll update this when I get the motor ready to fire up to see if they leak or work just fine.

I have been runing the 1200cc top feeds for like 5-6 months, they are way better than modded stock

I have another friend that recently got the 1200cc side feed will see how they work.

I've been running the top feed 1000cc's in my version 8 swap for about 3k miles without issues. I'll probably be switching to E-85 pretty soon.

Mine will be here this week. I'll post back when I get them dialed in. They're replacing 1200's with an in tank DW300lph pump feeding a Bosch 044 inline. The 1200's were maxed even with higher base pressure.
