My brother has a spare set of 550cc injectors from his car, how much could these be increased to and does anyone know which companies can carry this work out in the UK? Also, how much does this usually cost?

 

dont your brother fancy selling the 550s

Are they Phase two injectors?

darc

 

i believe turbodean had his 440's modded by Mark @ Lateral to flow...a LOT

 

Lateral Performance do the mod Paul.

This is what I run and they flow at 856cc ish at 3 bar static fuel pressure

I believe it is £175 for the mod but check with Mark for an exact price.

 

Thanks for that, will do. I take it latencies don't change with this mod?

 

They do marginally but not enough to worry about in the grand scheme of things.

 

apparently there is a thread on NAOSIC on how to do this mod for yourself, not seen it myself mind you but I have been told it's on there and is not a hard mod to do?

 

I don't have a flow bench in my garage though.

 

sell the 550's and mod a set of wrx ones

 

stock injectors are "restricted"

all you are doing is de restricting them, unless one of them is buggered, i would hazzard a guess that they will all flow pretty even anyway, a lot of aftermarket ecus let you trim each cylinder for fuel anyway

 

I'd rather pay someone to do it and get them flow tested for piece of mind.
