Shop has been tuning the new Haltech EMS for the last couple weeks . Taking his time getting to know the new EMS . Once he got to tuning in the upper rpm's [ above 6000rpm's ] he is running out of injector . He raised the fuel preasure 10 psi and then the fuel preasure started to fall off up top . So the 550's RC's arent big enough . [ FYI -walbro intank , return fuel system ]
So he may put in 750 or 850's in . What is the best idling larger injector you guys have worked with ?

THANKS !

 

deatschwerks 850cc injectors are my choice. they work perfectly for me.


largest drop in replacement available, plug and play...

 

PE 800cc i use it on my car and they work perfectly

 

^^^ This is what we were leanig towards right now . He'll have to wire back in the stock injector clips

 

^ if you already have rc injectors booger, get 750's I have them and they have always worked great. Idle and Start up is great

 

Yep, my car's running these. I'll let everyone know how I like them.

I had RC 750's before and am sort of indifferent to them. They were running on the UTEC and I had some warm start issues. Other than that they' weren't too bad.

 

I have the Rc1000 with a GTM 1K idle bump reflash and it starts right up all the time anytime (FCON).

 

As long as you go with a Denso injector you should be ok, HKS, Blitz, and PE all use Denso injectors. The PE are direct fitment without modification to your lower collector, so I would probally go with those or the Deatchwerks (if they are also a Denso, which I believe they are)

Good luck!

The RC injectors tend to have a irregular spray pattern and are frequently unreliable....I've had some bad ones.

 

a standalone or ECU flash for injectors makes a big difference in idle smoothness and the car starting right up






I thought Deatchwerks are bored out stock injectors?

+1 on Denso. They seem to be the best out there but also most expensive

 

I heard they are going to be using Denso injectors, but not sure.

i went hks 1000cc with my haltech.. i hope to have zero start up or idling issues, which i have been told should not be a problem with this combo.

 

that is correct ..

nice.... your idle will also depend on the cams you go with

 

Im pretty sure the shop is going with the Deatshwerks and wire back in the stock clips . I left it up to him .

Thanks guys !
you confirmed that we made the right choice

 

My HKS 1000cc have a good idle....I guess the Fcon does not hurt.

 

I agreee...stick to something Denso.....DW, PE, or HKS.

 

No love to Precision?

 

Nope, I have heard very bad things about those injectors, probably worse than RC. But again that is just what I have heard...

 

I have never personally used them, so no hard feelings . I just know that are really popular in the supra crowd.

 

Yea, They are also very popular with the EVO guys, but that is mainly because they are cheap, just like most EVO owners
