Those of your with a 2015+ Subaru STi should take a close look at this set-up as the power gains are huge and this pretty much maxes out the stock turbo without adding an alternative fuel like E85. If you don’t want something as loud as an EWG you can do without this and give up a little power and boost control.

Hello, I am looking at buying a 15 STI and will be looking to mod it in the near future. What would a setup like this cost? Parts and installed, roughly.
Chris Richardson
Due to the variance in the options for exhaust etc it’s difficult to estimate but usually, it’s around $3000+ for everything.

Hi, How long would it take you to set this on a 2015 STi ?
Thanks
Chris Richardson
It takes around 3-4 days with tuning usually.
William
How reliable will the engine be after these modifications?
ChrisTouge
With a good custom tune and proper maintenance, the engine can be very reliable and last for years and years.

What would you reccomend for a bolt on set up for a 2015 STI?
I currently have an Invidia N1 with a drop in K&N and Accessport installed.
I’m interested in the fueling/intake upgrades followed by a custom tune.

Id prioritizes getting a air box for your intake to ensure cool air. But like the post said ID1050x Injectors, DW65c Fuel Pump and STI Fuel Pressure Regulator Conversion.
