Injector Collars (What will work?)

[shotgunhunter4]

I am in the middle going ka-t and I have the Rx-7 550cc sidefeed injectors. I want to use the stock fuel rail and I know I need collars for these injectors but I am having a very hard time finding some that will work or ones that don't already come with injectors. Does anyone know if these will work for the ka?

If anyone has any further information or can point me in the right direction I would really appreciate it.

I have a solution for you. I just don't know if you have your injectors yet or no. But why not convert to a topfed fuel rail and run the topfed RX7 550cc injectors. From what I remember about reading around, there is a topfed fuel rail you can use from an accord that will pretty much be a direct drop in.

Just another option Im not saying do it .

yea, I already have the injectors. If i would have known before hand i probably wouldnt have bought the injectors. Does anyone else know about the collars.

you dont actually need collars if you can find same inside diameter injectors seals and larger outside diameter.

the reason for this is that the tx7 injector is narrower.

you can use the stock injector caps from the nissan injectors all you have to do is remove the little rubber piece inside.

what i did since i could not find larger injector seals is i had my machine shop make me some inserts that i jb welded into place, basically what these do is maintain the same outside diamter as the rail so they sit snug inside the rail but the since diameter is a tad smaller than the rx7 stock injector seals.

alright, thing is that i doubt i will be able to find the seals if you couldnt. I mean i would like to be able to just put these collars on top of the injecters and let that be that. Im now thinking of just buying a top feed fuel rail. any suggestions....
