Default WRX injectors in 2000 RS

If I wanna run WRX injectors in my 2000 RS, I either need the Rev-Lab adaptors or a 99 intake manifold, right? Are there any other ways to do this? I think i remeber hearing some problems with the Rev-Lab adaptors, can anyone comment on their fitment?

i have the adapters and there was a problem, what i did was had them lathed down 1/32" on the middle diameter that goes into the manifold and they fit perfect. its an easy fix if you know someone with a lathe.

Do the 2000 RS and the Legacy both have the same injector "mounting"? If they don't, maybe that's why you had fitment issues?

PhatSuby will confirm this, but I don't thing that Rev-Lab is selling the adapters anymore. You can get a set from Japanese Automotive ( http://www.japanese-auto.com ) but you will need to take them down 1/32 of an inch. They are not on his website, and you'll have to give him a phone call.

They fit a 2000 Legacy GT, no problem, but the later models and the automatic GT's share the same manifold as the 2000 RS.

PhatSuby can let you know how much they cost.. I'm using a set in my 2000 GT Turbo as well.

Also, Doodiehead is using the same adapters in his Turbo 2.5RS-T with the STI injectors, so it's a confirmed fit, if you take them down 1/32". I can ask Yoshio (Japanese Auto) to have them made with the 1/32 already taken off.

yea i had to wait for like 3 months to try and get a set of these from Rev-Lab but still didnt get anything. i talked to yoshio at Japanese Automotive and i got a set within a week, awesome!

so give yoshio a call and he can get you set no prob, and yea if you just have him lathe those down an extra 1/32" you will be gold.

hmm, I've been thinking about bigger injectors too, a set of these and a set of used STi injectors sounds like just what the doctor ordered

*bump*

So anymore news concerning these adapters?

Am i correct in thinking that i could pop a set of the adapters and STi injectors in my 2000 RS with stock ECU and it would all function properly?

The car will run much too rich at idle with a stock ecu. Even an AFC wont pull enough fuel for those to work correctly. You'll need an EMS.

I just bought these from Yoshio, does anyone have access to a lathe so I can get these to fit on my 4EAT 2001 RS manifold?

I just installed them in a 2000 intake manifold and all I had to do was buy bigger O-Rings

I bought them at a hardware store its the same inside diameter but they are bigger in outside diameter so the donut is fatty jajajaj They sealed pretty well.

the 99 manifold thing is a myth. I am using WRX injectors just fine in my 01 manifold. Just port the inside of the manifold at the injector holes for a better spray pattern. You also need the bigger o rings.

when you say "port" do you mean to actually machine or otherwise remove material from the manifold?

I just used my die grinder. Do a search on my name in this forum and you'll find some pics of side by side ported and not. It's also a great time to do some mild cleaning up of the runners.

what do you want to know, i just had mine out actually to add more o-rings cause of a leak, i was told i did not need o-rings inbetween the injectors and adapter but you DO need them.

the fitament issue i had was i had to machine 1/32" off the middle portion of the adapter.

however i think FJP is right, looking at the manifold, i suspected i could just stick the wrx injectors in with diff o-rings, the only thing i was unsure about was if the end of the injector would go down far enough to seal against the manifold wall. i dont know if this matters if you o-ring above it.

i just decided to play it safe and use the adapters, and now that the leak is fixed im all happy!

The 99 manifold thing is not a myth, it's the best way to get the best performance out of WRX/STi injectors. You can machine any of the newer manifolds to fit the injectors properly, but the 99 manifold is already done. You can get the injectors to seal in the newer manifolds by simply adding new o-rings, or using the adaptors but the tips of the injectors will not be flush w/ the inside of the runners. The tips of the injectors need to sit flush w/ the runners for the entire spray pattern to make it into the air stream for optimal atomization and performance. If the tips of the injectors are not flush w/ the runners part of the spray pattern will spry onto the inside of the injector bung or adaptor instead of into the air stream. Even the adaptors will not put the injectors into the runners as far as they need to be for optimal atomization. The performance trade of is probably negligible, but when you're trying to squeeze out every drop of performance the 99 manifold (or a machined manifold) is going to be the best way to go.

Thanks PHATsuby, I was talking to a friend of mine with with a CNC machine and lathe and we were thinking of starting to produce these, I wanted to get the pics that you posted here So I could see the fitment issues and see if we could figure out measurements.

I tried to fit a set on my 2000RS and they don't work.

IIRC The O-ring sits in the port for the idle air control valve thing.

Well Japanese-auto just billed my credit card for the adapters, so as soon as they are here, me and the fellows from Rallitek will have a project on our hands, hopefully I will be able to provide some more info after are install attempt.
