Default wrx injectors/fuel rails

I just bought a used turbo kit and it came with a set of WRX fuel rails. I was planning on using these to do the parallel fuel rail mod. If i go with the WRX rails, do I have to use WRX injectors? Will the WRX injectors even work with a 2000 RS?

here's some pics of what i have

yeah, new age wrx side-feed injectors are the same type as any 99+ impreza which is also side-feed. The O-rings should fit correctly since they are both made by FHI.

I've heard of a number of "fitment" issues when trying to put WRX injectors into an RS manifold. Apparently if you use two o-rings instead of one, it solves the problem, but it's not bullet proof.

I believe Rev-Lab makes an adapter that will allow perfect fitment of WRX injectors into an RS manifold. It's not on there website, but apparently they do exist based on a Turbo Legacy thread I recently saw.

Link is here ==> Rev-Lab

Hope this helps.

Cheers,

ahh ok, its the manifold that has trouble with the WRX injectors. So if I switch to WRX fuel rails, I can still use RS injectors?

uhhh don't u mean top feed? The older STI's are side feed.

the WRX injectors will fit a 99 manifold. The 2000 manifold can just be drilled out a bit or u can use the rev-labs adapters too.. but that air-assist **** is a pain in the A$$...

no. they use high impedance.

i also have a set of wrx injectors/fuel rails.. the fuel rails use different mounting points so i don't think they fit. the manifold on the 00+RS has air assist holes.. so not sure if the injectors fit either. also have a set of rev lab injector adaptors which didn't fit at all.. not sure if they corrected the problem since..
