2015 wrx upgrade turbo
We understood that emission conscious places like California and Japan require the standard cat to be run in the OEM position. The reason for this was to allow for the fitment of the standard setup factory or aftermarket exhaust system. We supply and fit a short turbo outlet adaptor that goes on the back of the turbocharger. We also use a stainless perforated layered turbo base gasket and turbo outlet gasket. It is put together with Inconel Studs and 309 Stainless Nuts to ensure heat will not affect the tightness and therefore avoid possible exhaust leaks. To ensure reliability we pre-assemble the kit. When using the AVO MAP and ECUTEK, you must use our 3 Port Boost Solenoid to work in connection with the standard boost valve setup.

Where the ECUTEK is purchased through AVOTurboworld the MAP will be free of charge. This MAP will be available with every turbo kit at a small additional charge if you are using ECUTEK. This is all been achieved via ECUTEK and the expertise of AVOTurboworld’s Ross Wilson.
#2015 WRX UPGRADE TURBO PLUS#
To make the whole package work we have come up a good ECU MAP that incorporates all the usual changes required to be modified in the standard ECU plus MAP switching with 3 different boost control set points and some nice changes to the CVT to aid in smoother and faster gear changes. Our billet turbocharger is very linear and delivers smoothly across the rpm range. The other reason for the turbocharger choice was that due to probably a large proportion of the vehicles being fitted with a CVT, we did not want a laggy turbo that all of a sudden increases torque and power over 1000rpm like some and then puts major pressure on the CVT. We opted for a billet turbocharger that was going to max out at about 400hp at the engine with standard compression so that it was responsive down low and also could rev to redline. This would mean designing the manifold slightly unequal 4 into 1, it was not easy to do within the confines of space that was available but it was achieved and with the standard position exhaust system still being able to be fitted. While designing the kit, another aim was to make the boxer sound more prominent compared to its non-existence in standard trim. So we thought to do this properly that a whole turbo kit which included manifold, turbocharger, oil and water plumbing, inlet hose from airbox to turbocharger entry and intercooler hose from turbocharger compressor outlet to hot side intercooler entry would be necessary. The detonation issues then led to engine failure. Once boost was increased even with an upgraded exhaust system, the back pressure caused by the small manifold runners and small turbocharger increased to a point where it caused cylinder pressures and then detonation issues. AVOTurboworld after much testing with the WRX 2015+ vehicles concluded that the standard turbo and manifold setup was a major restriction when wanting to increase your horsepower and torque.
