bosch 550s or 630s depending on what power levels you want to go for.

Plenty of scaling information available and correct spray patterns, no issues with idle etc
 
Which size of injectors do people recommend for a 2.0 20vt, large port, SEM,R32 TB and gtx2867r not decided on which hotside yet.
 
I'm running 550cc Genesis injectors on my Stroker GTX2867R setup, which seem to cope pretty well. although I intend to upgrade to Genesis 630cc when my cars goes in for custom mapping just for peice of mind.
 
Seems to work pretty well actually. Really happy with the low down grunt the 2L adds. Really needs a custom map now, which I hope to have done towards the end of the year ;)
 
bosch work well
Siemens not so much.. linearity issues ... result in wildly swinging lambda adjustments
