Hi i recently bought a intake manifold from some one, he said that it had been removed from a 2002 and had engine work at scooby clinic, so im just trying to identify what cc these injectors can be as i have 2003 wrx and would like to upgrade mine.

 

I think the grey ones are the standard wrx ones. The normal next step up would be STI pinks.

 

I'm pretty sure Standard blue should be 440, that's what came off my 04WRX when I upgraded

 

Look like standard bug WRX Injectors to me........one option is to get them re-flowed to a higher value. Milleniumracer on here used to sell re-flowed injectors like these. Other option is a set of STi pinks.

Edited to say that at a higer fuel pressure these can flow quite a bit of fuel

 

Oh so they won't be an upgrade probably the same as what's in mine at the moment,
Does anyone know how much it is to reflow them and who does it?

 

410cc Blue WRX Bugeye standard injectors. Don't modify them unless you have after-market management is my advice. You can make them work for roughly 340-350bhp by upping the fuel pressure as Shaun suggests.

I have sets of these modified which are cleaned and flow matched at circa 850cc as close as possible for £150 exchange.
