could someone please tell if the injectors from an STI 4 will fit a version 2?
Thanks Jon

 

Jon,

Yes they will. It may be worth getting them cleaned, and flowed first though, and also make sure the "O" rings/seals are in good condition.

.. and the injector filter baskets too.

Thanks for the good news , I was under the impression that they were different after talking to Torque developments . They said they could supply some bigger injectors made by HKS but thought that they wouldn't fit , b4 I order some has anyone fitted HKS injectors into a V2 ?

 

As far as I knew, the HKS injectors are low impedance (maybe now they have the right versions?)

Double check on this first

Jon,

the injectors will fit just fine, it's only version 5 upwards that are problematic. Just be aware that the car will not be able to cope with them on the standard engine management.... the last one I saw like this ran over 10% CO on idle ! The ECU just can't pull back the fuel enough to compensate. Dropping the fuel pressure DOES NOT help, it still runs rich on idle but leans out on boost (ooops). If you have a programmable ECU then it shouldn't cause you any problems. I've had a set of 480cc injectors in a version II and they worked just fine with a PossumLink.

Cheers,

Pat.

 

I'm with J (Firefox) as far as I'm aware, HKS don't do injectors for the Subaru, regardless of which version !!!. Unless they're a new product.

Subaru 440cc injectors will be more than adequate for most mods, 480cc's for circa 360bhp, and 550cc +++ are available if you're mad, like J

I'd speak to someone who knows what they're talking about, like Firefox, Pat, BRD....

Mark.
