Injector Size for 2.5 Engine?
WHEN I get my STI MY03, I will be fitting a 2.5.
I have:
New 2.5 Short Engine - Standard US spec
TD05/6 20G Turbo
Gruppe S headers
I will get:
Uprated Pump (Prob Walbro)
SX? or other uprated reg at 3.2bar
TEK Remap
STI variable valve heads
Standard or APS topmount.
BUT,
What size injectors will I need?
Standard 500's will obviously be too small. What is the best Size?????
What vehicle is the best donor??

Yeah, I know, thats why Ill get them
Just trying to set the spec!
The only things I have left to get, are the Injectors, Pump and Regulator.
Im hoping the 'host' car will come with Exhaust and chassis mods.

I'd run the 500's at 4 bar pressure and see how far you can get. I assume you wont be able to run that much boost at high revs with the 05 exhaust wheel anyhow, and I'm maxing my 440's out at 4 bar on an ej20 with 05/06.

You don't actualy need to fit a fuel pressure reg on a new age if remapping the factory ecu, 650's will be fine with that turbo. You would need 800's for something sized like my STi5 turbo though. I use 740's with that. The std reg with Walbro runs fuel pressure at 3.3 bar above boost/vac so already there.
