Trying to decide on a set of injectors for my build. I have a basic built motor going in, and looking to hit around 450-550whp with a few different maps on tuned with a UTEC.

I have done a bit of research on the different sizes and brands. I know I will need at least a 550cc up to maybe 750cc for this power range.

RC - I have read that RC's idle a bit rough b/c of their spray pattern but can sometimes be cleaned up with a good tune.(sharif will be tuning my car when the build is done). I have looked at these b/c sharif offers a plug n play solution for the injectors. Not sure if these are true drop in in the since of needing spacers, etc..

HKS - have heard they are top notch injectors, made by denso, not sure if they are drop in or have to hardwire?

PE - I have read that these are also a good choice but, havent heard to much if they are complete drop in or have to harwire?

Pink JDM STi injectors - these should be 565cc iirc, and are direct drop in and use oem plugs, correct?...Will 565cc be ample for my power levels, and where can I get 6 of them brand new?

Deatschwerks - Refurbished oem injectors...should drop in and use oem plugs, correct?

Basically I am primarily looking for the best performance/spray pattern, while creating less hassle on install as possible. Any suggestion on which of these fit the bill? I was thinking the STi denso's or Deatschwerks would be my best bet...

 

my tuner is using rc750's in my new setup. my goal is 500-550 on the single pump, and once the cjm twin pump comes out, 600-650whp. if your limit is 450-500whp, i would do 650's. just my opinion. if you want more room to grow, do the 750's. carv2 had a 350z shop car( just got sold) that idled fine and drove great on rc750's. sorry to sound cliche, but it's all in the tune.

 

plus with the rc injectors, rc sells clips that match up to the factory harness, so there is no cutting or soldering.

 

PE are a drop-in by report (specifically made for the car by Denso for PE).

So logically, you should be able to find drop in Denso injectors, and I do believe GTM sells those...

I'm just not sure if they are the same spec as the PE. Ask Sharif, I think he can source one of these (at least he's going to for me!).

 

Denso=PE. All PE does is make the right spacers for them.

 

thanks mia. i was confused because the cc rating was different last time i researched this - but then again, i didn't know what psi those cc ratings were for either...

 

Well for instance the Turbonetics kit comes with Denso 380cc injectors from Turbonetics. Put them side by side with the PE380s and they are identical.

 

i have 550cc for sale...when i had 431 rwhp and a walbro(255) my tuner said they would go to about 450-475rwhp...good luck

 

any tuners or shop owners have any suggestions/advice? I might end up doing the 650cc RC's with the clips...who sells the clips that are plug n play with the stock connectors?

 

ForgedPerformance.com has the RC injectors w/ clips

 

Deatschwerks will drop in with no need for clips or anything of the sort. They will fit exactly like stock, just flow better.
