hi guys,
i have just bought a ra with the 5th injector,the std one in the center of the inlet manifold, question 1/ is it a working one? question 2/ if not (as i beleve) how do i get it working? cheers, robinh20. |
I believe that Link and Apexi both has add-on systems that can control it for you!
Speak to Bob at BRD - he'll help:D Russell |
Hi Robin,
Have you tried a search, IIRC someone on here did quite a lot of investigation some time ago (Andy F. I believe)on his and found it to be non-functional. Also the OEM ecu work required to get it working (at the time) looked a bit of a job. Cube. |
Correct, it is non functional as std. Its location suggests that it may not distribute fuel very evenly to all 4 intake runners.
I'd go for 4 bigger injectors if you are looking for more fuel flow capability. Andy |
I thought the fifth injector was for water injection? I seem to remember reading that somewhere recently.
|
does anybody really know what it is for?
i mean sum people on here must have had dealings with a ra rally car or sumthing that used it properly ive always wonderd about the 5th injector |
thanks guys,
as i suspected! not working! it must be a rally thing :O andy, i will have to do a few bits and bobs b4 i need more fueling, ie forged pistons and new rods ect, i want this one to be RELIABLE!!!!! so i hope you dont mind me picking your (and everybodys) brains in the coming months!! :) see you at jvs! cheers robinh20. |
the 5th injectors on the RA motors is for cold start, its to small to of any use, you could use the slot in the manafold for water injection or for another injector, but if you are running a little lean, its time for larger squirters, rising reg and a bosch pump...

I have a control module wired into the ECU on my 95 RA, I suspect it may be an external controller for the 5th injector, will be testing it this weekend. Still unsure of the benefits (if any!) of having this functional?
Could use it to control NOS I spose ;) :D |
I asked this question months ago and again most people said it wasnt worth it?
A friend had this on his car. He had STI Type R with: Full trust system Trust blow off Aftermarket ecu Greddy boost controller 5th injector kit. Trust FMIC That was it. He pushed 380bhp out of his STI and he said it was popping and flaming like mad - but very quick on high boost. |
