Default Rebuilding my 05 Wrx, 2.5 plus some

You may have seen me pop up on the newbs portion of the forum introducing myself and blabbering on. Well here I am with the important stuff haha.

So I picked up my 8th or 9th Subaru haha. My 3rd Wrx, think Iíll keep this one a little longer this time.

About the car, 05 Black, clean title, 132k Miles. Previous owner Lost the short block, havenít torn into it yet.

I picked up a complete ej25 from I believe an 06 Wrx with 65k mikes (what I was told)

Engine has avcs on intake only, I have read around and it would seem that I could change the cam gears and crank trigger out to the 05 along with sensors and run the heads sans the avcs ?

Along with the motor the guy gave me an act lighter flywheel, helix downpipe and full exhaust(forgot the brand) the complete intake manifold, ac comp, starter, alt, complete factory exhaust manifold and up pipe, upper harness and some other evap components I believe.

Iím looking at a doing deadbolt 20g turbo, up pipe, and injectors, and a clutch Along with either an AP or something for tuning. I am an hour from LV so Iím sure there is a reputable shop to tune as well.

Will also be doing head gaskets and all timing components, water pump.

Car already has a k&n cai

Well I just bought the deadbolt 20g for a great price so whoops lol

What injector size would be good.

Forgot to mention I bought a walbro 255 pump assembly already as well.

ID 1050s would be a good choice for the 20g. I have ID 1000s and run an 20G-XT. I'm about 60-65% duty cycle at WOT so there is a lot of headroom left. You could go smaller, but might as well have the safety margins and the larger injectors aren't much more money than 800s or whatever.

I'd ask your tuner what they like too.

Is the CAI a true cold air intake, or is it a short ram? If it's a short ram I would go back to the stock airbox setup. I had an SPT short ram and it was ok running a TD04 but caused problems with a 20G because IATs were all over the place making it hard to tune. It was just sucking in hot air from the engine bay.

Thank you for the reply, I was beginning to think I was all alone haha.

The intake is a short ram, I did get the factory box with the car also. I might go FMIC not sure yet, might flip the manifold even. At this point itís a snowball effect haha. Iím going to toy with it a little. Possibly machine a spacer to retain ac and alt locations
