triple.
I would go with a vf39 for daily driving and not much more on the 2.0 motor I spool at 3200-3500 RPM. I made 280whp on stock cat back and stock inter cooler. Injectors are a waste of money for that setup you can just do the circumcision mod. Every single injectors from the factors has the exact same piston above the cap and they flow ~823cc. Its not a issue to tune. I only noticed one slight problem with my setup is that during intial warm up on a cold day it runs at ad rough but as soon as the cars up to temp thats fades. away
If you want info about the EJ205 / Spooling / injectors or anything give me a call. BTW search nasioc you will see that my 280 setup is a high about of whp for what parts I had.
Tranny wise I would start savings now and eather go with a STi RA gearset /build or a STI 6 speed swap.
IF THIS CAR IS A 02 AND HE CANNOT AFFORD A TRANNY SOON DO NOT UPGRADE!
