To answer the question, no matter what you do, you will need to tune again. What does the tuning cost you? Is this 25-30hp your final, end goal or are you going to want to change it up in the future? E85? Meth injection? NOS? Bigger turbo?

Why all these questions, you ask. Well, because tuning ain't cheap. It's better to have some final goal in mind and save up. A friend of my son got his STi tuned recently. It cost him Eight Hundred Bucks. He did it once and he's done. All the mods were installed and he drove around on zero boost to get there. But he's done. If you add 35hp and then think "Zoink, I should add another 50hp by doing something else". Well, guess what? Another Eight Hundred Bucks to get it so it won't blow to smitherenes.

So with all these explanations......what kind of money do you have available and what's your final goal for this car? Might our answer end up being "R32 GT-Rs are available now legally and they came with a manual transmission...maybe you should consider one of those" because guys have been known to spend stupid amounts of money on their STi only to find that they could have bought themselves an R32 or even a brand new GT-R, if they could put up with the dual clutch.
Yes it would be my final tune and final hp mods, budget is 2500$-3500$

On stock turbo:
Injectors, fuel pump, flex fuel if e85 is nearby, tune.

Keep an extra $3500 around if you pop the motor.

Motor has just been rebuilt all internals replaced, forged pistons, etc , spoke with the tuner briefly and he suggested going 20g turbo and Cobb accèsport along with the usual suporting mods for bigger turbo , injectors, fuel pump , ecbs , not sure I want to go that way , also said I wouldn’t get any hp gains with headers and a cat back exhaust, which I found a bit concerning, also when I asked him if he could increase boost from 17 psi to 18or 19 psi he said I would lose timing, ?? Does this make sense ?

And here's the problem.

Your first post said stock turbo.

Now you're switching the game and considering a turbo upgrade.

You're all over the place.

You need to do some research man.

I like this build.

But seriously you need to figure out what you want.

Bolt ons will improve efficiency, but the turbo makes the power and is the limiting factor. You can change the turbo for easy gains, or change the octane of fuel for more boost/timing. A 20g is a great choice, will spool like stock, and provide you a nice boost in power. Especially on pump gas.

See what your turner says. Equal length headers, fuel pump, injectors, ebcs, intercooler, dp, turbo, would be a great set up for pump gas.

Does improving efficiency mean it can produce more power? So for his power goals, a bigger turbo isn’t really necessary.

I'd submit that you may not notice 30 hp difference. That's a lot of money to spend on potentially nothing.

Default 25-30 hp

I submit that an uppipe, downpipe, Catback, and retune is good for 30hp all day long.

... of course... I remember one time I was wrong. That was long ago and I was young.

He is a downpipe, intake, and tune. Sounds like his stock turbo is pretty maxed out already.
