That depends on the part you are installing.

Correct.

Unless you can afford the dyno time, have all your mods installed at the same time, then flatbed tow (if necessary, but DON'T DRIVE it!) the car to your tuner.

 

Back on topic:

What mods are necessary if you go with a larger turbo?

Also, what is a respectable upgrade from the stock IX turbo and why?

 

Everything I listed would be needed for a turbo upgrade. For you cause you seem very new to turbos and boost I would say an BBK Full or FP HTA Green or Red. The reason why is because they are a stock bolt on turbo. The BBK and FP HTA Green spool better then stock turbo with more top end. But like I said I suggest you do the stock turbo upgrades first before swapping turbo...One thing I didn't mention is you should get cams for a turbo upgrade.

 

I think most people group their mods into stages. Some don't require a tune but they just won't add much power until you do (fmic, piping, less restrictive exhaust).

If you're changing your intake then you should have an a/f gauge or get a tune unless you know the car's tune is stock (Evos run rich stock so the stock tune likes intakes). Injectors and boost mods are probably the ones I'd just have the tuner install pre-tune. I've been told the car will barely run on E85 without a retune, so that's best done by a shop.

 

What is your goal, just a few more ponies? If so, just get a cat back exhaust and a down pipe, and maybe an intercooler. If you want 400+whp, you will have to do more mods. Just think of the motor as a pump, new turbo flows more air so that is why peeps redo their top end, valve springs, retainers, cams; etc. If you can flow more air you need more fuel; walboro; injectors; fuel rail; fuel pressure regulator; etc.. If you have more fuel and air, you need more spark to ignite it all better; new coils; plugs; etc... If you have more power, you need better brakes; cross drilled rotors; new calipers; pads; etc..

Think of the modding process as your roadmap, and your goal is your destination. You have to now where you want to be before you get there.


Here is a crazy idea, why not take the car to a respectable tuner and ask their opinion?

 

I don't expect you to read the whole thread, but my car isn't stock.

I don't have a number goal, I just want to increase the power from where it is now by adding the part that will net the biggest gains. I'm willing to do a few other parts if they necessarily need to go together like an upgraded valve train with aggressive cams so I don't float a valve, etc.

I would like to make decent, reliable power for my daily driver. I don't want to mess around with internals, remove the head studs or spray NAWZ into my motor.

While I'm at the office, this is a better solution from my desk.

 

Yea do some of the mods a little at a time like the pump, o2, licp then save for the turbo, cams, and fmic if you decide. Don't be like me and have minor bolt ons and do a turbo upgrade, cams, etc. all at once! I am impatient..

 

Oh God is he.

 

He comments on all of my posts! ^ Shut your mouth when you talk to me!

 

Listen buddy you would know nothing without miy help. And don't forget those free baseline runs your getting......who worked that deal for you ME

Can everyone in here just listen to me especially the OP look at the sig I think I know what I'm doing and speaking about. Get an o2 housing, fuel pump, and MBC and a good tune and you will have about 330hp

 

I'm not questioning your knowledge by any means, but I want you to understand that I already have an MBC and a few other modifications.

Would an O2 housing and a fuel pump be a better "bang for the buck" modification instead of a new turbo (FP Green? No idea...), injectors and a fuel pump?

 

What he said but it all depend on your goal

 

go to AMS or Buschur website to find their recommend stage of upgraded parts

 

What about something like bolting up an FP Red with the 80mm housing?

Will that work with stock injectors and fuel pump? What needs to accompany modding the turbo?

 

Your just asking for death to your engine..Just do the mods that are suggested. There are multiple posts in this thead that tell you what to do.
