VF40 Subaru Legacy GT/Outback XT
Also works on the 08 plus WRX!
The Legacy GT has a IHI VF40 turbocharger from the factory. Factory issues with oil starvation and contamination caused many early deaths of these units (most of which failed within 50K miles). The factory turbo oil supply lines have 3 restrictions built into the hard line. Two of which are .055" and the other is made into the banjo fitting on the top of the turbocharger which is .062". The factory banjo fitting in the head that feeds to the oil to the turbocharger/AVCS has a pressed in screen which often gets clogged by debris coming from the head. If you remove this screen, the turbocharger will get contaminated and die a miserable death. If you leave the filter installed, it will fill up with trash and starve the turbo from oil and again die a miserable death. Another common problem with the 2.5 engine is there are 2 solenoids called the oil control valves (OCV's) which are mounted on each valve cover. Those solenoids can and will malfunction. When this happens the oil pressure reduces drastically to the head causing starvation issues for the turbocharger. You should replace the OCV's at 75K miles as a maintenance procedure or if you have seen multiple turbo failures. The OCV's at the dealer are around $90 each.
The oil supply lines must be upgraded in order for BNR Supercars to warranty. The upgrade must consist of a high flow line with an inline 10 micron filter element.
The IHI units are also not known for reliability when the boost is turned up. Instead of using the VF40 turbo as a base of the turbocharger upgrade, BNR Supercars offers 4 hybrid turbochargers that take place of the IHI CHRA (center housing rotating assembly).
We now have our own compressor and turbine housing castings which eliminates the core exchange program. Customers have 60 days from purchase date to recieve core refunds. After the 60 days we can not give core refunds.
BNR Supercars has the best quality controls, and all the assembly and balancing is done in house! A 1 year warranty comes with every turbocharger we manufacture.
