Default Another Injector thread...

OK, there's been a half-dozen discussions here re : RX-7 Injectors, Denso Injectors, STi Injectors, etc...

Besides the handful of individuals that have used STi injectors, and the one or two using RX-7 ones, has anyone actually been able to acquire a drop-in replacement injector from someone like Denso? If so, where can I find some? If not, where can I buy a set of STi injectors without being horribly raped on the price?

Thanks.

This has been fully covered try searching next time and you will find an answer.

I had a group buy on the 500cc injectors that flowed at 550cc but most people backed out, obviously they donít know a deal when they find one.

The price was $470 for a set of 4 shipped.

Now I am waiting for my 800cc injectors.

I did do a search, and if I could have found a definitive answer I wouldn't be asking. Chill.

What I'm trying to find is a line on the injectors then, I knew about your groupbuy but at the time I thought I had another source. Now aparently I have no source at all.

So, that being said, how the heck do I get injectors?

Buy STI Injectors.

Contact WRXONLY Iím sure he can order them for you.

I will not be doing a group buy on the 800cc.

I had the sti injectors - they were extra good

But now I have something even better - - the beuatiful Black specials from RC -- - call them up RC - they have low impedance injectors that fit right in - - all you need to do is shim the fuel rail up about 7 mm's - everything else is a perfect fit in !!!!

Thanks Al, I'll call RC this afternoon.

What do you mean by 'shim the fuel rail'?

EDIT : Wouldn't I also need to wire a resistor inline on the injectors to change them to high-impedance?

I also recommend WRX ONLY for STi Injectors. Quick and curteous service. Adam @ Z1 has also been very helpful

You just put some longer bolts under the rail and some washers

I run stabnd alone so imedance is not an issue for me !

Let us know what you find out? I'd like to know the RC part number and cost.

Talked to them this afternoon.

They'll custom make any size from 600 - 880 (I think) for $185/ea.

For that, I'll stick with STi injectors for the time being. Not worth it IMO considering I'll have the whole low/high-impedance issue.

RC is a good source provided you can get a Bosch application (which for a WRX does not exist). Their custom made units are all Lucas injectors which are bored out=failure city on DSM's, not to mention RC is "infamous" for shipping injectors that flowed less (sometimes significantly so) than what they were claimed to be. For the money, the STi's are the way to go....at the very least, you know exactly what you are getting, you know they are a factory issue part, and zero modifications are required.

Yep I agree with Adam and that is why I got my STI injectors from him. BTW Adam when are they going to arrive?

Hey Adam - happy new year!

The sti's sure are real nice! But the RC's are good also

They came with a nice flow test print out so I know they all are the right flow rate and are evenly matched!

They have an interesting fog spray pattern - - not like the twin beam of the sti - but they seem to work well


Might try to use the sti injectors with the stand alone and see which injectors are better

BUT seems I have more than enough fuel now as even rich all the way at 11 / 1 a/f I max out at 90 % and usually I run much leaner so I',m mostly at 82 - 83% even at 19psi
