Why you write about stock headers?? You think headers not give power?

 

Power2price from headers is not worth it...6-7hp more

GT30R's 997tt ran stock ( ported ) headers

Coolers not needed now

I would check out the thread listed above, i just did a VR 700 with only 1.1 Bar.
Intercoolers are very important, when you add power you need more cooling introduced, i just had this experience so i am not quoting you a book.
Exhaust, you can go for a Miltek or Fabspeed, there are plenty of other good ones out there, just go with a 200 cell cat.
ECU, i just had mine done by Softronic, they did a great job, no check engine light, no hesitation or issues period.
I went with larger VTG's, worth every penny but you do not have to do this if you do not want to.
Hearders are good to add but really not needed to get to your 600HP range.
but i do urge you to check out the Thread posted about the VR700.

Good luck!!

 

don't get the headers, you don't need them at all

 

Exhaust with cats or with out?


And what good intake ?

 

Switzer )))

 

headers may add minimal HP, but improves throttle response and brings turbo into boost sooner. plus sounds great. get the headers!

 

+ 1...plus they are not that expensive, compare to the price for the car you will pay )))

 

Some tuners say that headers increase lag

 

Who ???

 

if your running stock turbos run the stock headers.

 

Protomotive does not suggest to change headers even with modified VTGs only when shifting to Garett

 

Proto 700 Cabriolet! Should be incredible experience with the top down...

 

we will find out in a week

 

That's exactly what I have today with BMC air filter (SPI Stage 2). According to Tym and depending on fuel quality, should see over 500 HP to the wheels.

No intercooler mods required for this stage. I did however add silicone hoses.
