sard injector collars

[skylite]

hi. im just wondering if anyone has or knows where there might be some pics of the sard 550 side feed injector collars. im thinking of getting some 550ss injectors but the collars are about $40ea. i was thinking if they could be matched up with another local setup available at the good ol wreckers perhaps.

They are D-speed collars, but i think they are the same. Good luck finding some at the wreckers.

hmmm may have to modify originals perhaps.

I used 20B 550cc injectors and turned the collars up on a lathe. Cost me less than $500 all up.

just buy a set of nismo 740cc injectors.

straight fit for the RB25... and if your running a PFC, no idle problems at all.

thats what im running and the idle is better than what it was factory IMO.

just make sure your oxy sensor is working

Yes dont buy sard injectors with the collars, they are shit.

Yes I have sard 550cc injectors with the collars

inasnt do u mean the injectors are shit or just the collars? I have called a few places in reguards to 20b injectors but no ones got any.

They are meant to be straight fit but they are not so easy to fit, even with the collars.

I still have a few problems with mine with regard to sealing.

Spend a bit more and get the actual direct fit hks or nismo ones

Try Dyson Rotary. I bought 3 off him, and another 3 off a guy on the Ausrotary forum.

If you want no problems and are willing to part with $1k or so, get the Nismo's. If you don't mind a challenge, have access to a lathe, and want to save a lot of coin, go the 20B's. Just had mine cleaned and flowed, and they have an excellent spray pattern.

dont the rotary injectors have a different spray pattern to normal injectors??

Here is a pic of a 13B injector (left), 20B (centre), not sure of the injector on the right, but it looks similar to a standard RB25.

The 13B is a standard pintle type injector, the 20B is the same but has an aluminium cone on the tip to atomise the spray better. So i don't believe the spray patterns are any different to other pintle injectors.
