evo lll 16g

I just put a new EVO lll 16g turbo on my 02 wrx and now I know I need to upgrade the fule system but I don't really know what I need. What size injector do I need, will a 190 fule pump work or do I need 255. and one last thing will the stock fule pressure regulator work or do I need an adjustable one. Thanks for any info

get 650cc injectors so you have head room, fuel pump is a question for tuner (but should be used) your fuel pressure regulator should be good, make sure you have the other supporting mods for that turbo, tbe, intercooler, some type of engine management

You will need a bigger pump for sure. Stocker will go out soon anyways. Did you get a 3port BCS yet ? Pick one up before you get tuned (ask your tuner) which he prefers. Nice charger BTW.

Oh and to comment on the fuel pump. The status quo is the Walbro 255, but AVO also makes one that flows 245 and cost 3x as much... It's apparently a better pump from what I've heard.

Walboro 255's are pieces of crap. Buy one anyway.

Just about Jack n Sh!t if the motor is off a USDM STI. They're two different engine sizes. If it is a JDM STI engine or EJ207. The you could swap out some stuff, but I can't get into specifics, I don't know enough on EJ207s.

I think the heads will fit, but if its that cheap grab the intercooler and injectors off of it. Then you'll just need the fuel pump and bcs before your tune.
