I want to upgrade the 440 cc RC Engineering injectors that came with the Greddy TT to 550 cc. Which ones do I want - high resistance saturated or low resistance peak and hold? Are all RC 550 cc injectors the same - some sites advertise different stock numbers for different vehicles - do they come in different shapes and sizes?

Any info would be welcome - thanks.

 

you need the HIGH SAT... its the same at the 440 you just plug and play... of course you need to have the car tuned/scaled for 550cc

 

OK, great start... That leads me to the next question... The lag adjustment for the 440cc was 0.64 msec, do you know the lag for the 550cc? Where do you get this kind of information?

How much do you want for your 440's? i have 380's and i don't think they are enough.

 

Hey - good call; I hadn't considered offsetting my purchase with the sale of my old injectors... Why don't you split it with me... $300 for you, $300 for me? (New ones are about $100 a piece.)

 

dude theres tons of used injectors on the forums dont buy new there's no need.

The delay is on the tuner I dont mess with that. Every motor/setup is different

 

I've been tuning myself because there are no good tuners within a four-hour drive of where I live. The e-ultimate has excellent graphs that make tuning pretty straightforward. Does anyone have some RC 550s lying around so I can give my 440s to coupes-r-****?

 

look on my350z i think I saw some 650 which is still fine fore a few hundos

 

deatschwerks!!


in stock, we try not to use any other type these days. they work flawlessly.

 

Do they have the same connector as the RC 440?
