I know I should've used the search function, and I did. But it's a bit difficult to find matching information.

My question is as simple as this:
What can I do with these mods (currently on my shelf, floor, garage etc..):
-Apexi N1 Catback
-HKS Downpipe
-Apexi Power FC
-Unorthodox Full Pulley Set
-Greddy 2-row FMIC
-Greddy Intake

I rebuilt my engine last year and it should be in perfect condition. I have the stock turbos and fuel system (+Power FC).

When I install my mods, can I (and should I) adjust boost? And how much?
What kind of power-increase should i be expecting here?
Should I get a midpipe? a fuel pump? injectors?

Thankful for any information!!

 

You should be able to run a minimum of 12psi without any problems, or worries, if your car is tuned right.

 

Thanks adam c!
Anyone else have oppinions??

 

Running 12psi should be fine on your stock fuel pump. If you're planning to run above 12 psi then I would run all 9 plugs. Get your power FC tuned for your mods.

 

You make it sound like all he needs is all 9s in order to safely boost out of his mind, which isn't the case. I'd be running all 9s already. Think: "fuel system."

 

You could put them on the car.
Sorry , i just had to

 

I had it comming..

 

In the time it took you to write this you could've had the cb and intake installed!

At 12psi you should do around 300 to the ground. Be sure to have the PFC tuned good so you don't pop it.

 

Once you install those mods you should notice a very nice power increase. You'll feel your car pull better and run smoother, especially because of the upgraded ECU and the downpipe.

You should be able to safely boost 12psi for street/normal driving, and you may be able to do possibly up to 13-13.5psi for drag. Remember to turn boost back down after though, thats not really good for street driving.

You should be looking at close to 290-310 HP at the wheels with everything properly working.

 

yea, fuel pump. To easy to turn up the boost.

 

Will the stock injectors be sufficient?

 

they will be good up to 14 or 15 psi max

I think at 15 psi they are at 80 or 90% duty?
