My car has a remap and EP 1, running 1.2 boost. Garage said car is around 545hp. Without changing the turbos is there much more I can do to increase power. I was informed anything more I would have to get gt2 rs intercoolers.


Any advice appreciated.

 

im pretty sure you're gonna need to change your clutch real soon if you increase the power from what you already have, but if you want to push your stock turbos a little bit more then you can change the injectors and run E85 with a a re-tune

 

You have lots of headroom with the stock turbos and your mods. Next would be better intercoolers and some turbo inlet hoses. Those combined with a custom flash will gain a lot of power. Enough to vaporize your factory clutch, haha. After that, bigger injectors and E85 is the way to go

 

Thanks for the replies.


Its a tip so clutch is ok.


Hoses and intercooler would just manage the existing power?

 

GT2RS (997.2 turbo) IC's is an easy choice, then go for Injectors + E85 if you have it available.

 

turbo inlet pipes, IPD plenum and TB, intercoolers, remap for E85 or racegas. you can squeeze the stock turbos pretty good with the right combination of supporting mods.

 

You could have a bit more power in midrange without intercoolers given you're at 1.2bar especially if your sort of driving is mostly on the street and not extended high speed pulls/road course that would involve significant heat soak.

Bolt-ons basically what others have already suggested, intercoolers (OEM GT2/997.2 intercoolers are a great budget option for stock VTGs) and turbo inlet pipes such as those from do88 if you're looking for a budget option.

Once the clutch is changed out then you can look further into E85 (if you have it in your area) or meth injection. For E85 you'll need larger injectors and on OEM VTGs you won't need higher than ID1000s.

82mm OEM GT3 throttle body and the matching sized IPD plenum would probably be a worthwhile mod as well at higher airflow/boost levels. We personally haven't had a chance to verify exact gains on these with OEM VTGs and E85/meth. If I had to guess given what we've seen so far I'd say they'd most likely be worthwhile doing.

Lastly, in terms of what not to upgrade, leave your stock intake airbox alone

EDIT: Check out this thread by @A418t81, basically summarizes what I wrote above with real world results:

EDIT 2: I boldly assumed from your post that you have a 997.1 Turbo since you said that someone suggested gt2rs intercoolers to you. If for some reason you've got a 997.2 Turbo you won't need the "gt2rs" intercoolers as you've already got them. Having said that you have more some power in there through a retune without any changes to other hardware given 1.2bar currently, especially in midrange.

 

What about upgraded Y-pipes? Any benefit at 1.2 bars?

 

I suggest running meth .... Best Mod for these cars esp if you have bad fuel or weather ( we have both) .... From there you can run a more agressive map, and some run it with stock IC and get same performance if not better than cars with swapped intercoolers ...

 

My results from upgrades with stock VGTs........I do not plan to go any further at this point, the results keep me plenty happy on the track and street.

Agreed. Exhaust+Meth with an appropriate tune will do wonders performance wise on an otherwise stock car...minus the OEM clutch
