" APR is pleased to present the Stage 3+ High-Flow, CNC-Ported, Performance Cylinder Head for the 2.0T FSI (EA113) Engine.


APR's engineers have optimized the FSI head with proprietary, computer-controlled porting conducted on APR’s in-house 5-Axis Centroid CNC machine, our engineers have increased airflow by 17% on the intake ports and an additional 12% on the exhaust ports. The engine’s boost-to-airflow ratio is reduced by roughly 10% while also reducing intake air temperature and alleviating backpressure. As a result, the spark knock threshold is extended up to 7 degrees allowing for a substantial increase in power.


Through specific Stage III+ calibration changes, this directly translates to a +70 HP gain over APR’s existing BPY, AXX and BWA Stage III Turbocharger System on 93 (R+M)/2 octane fuel and up to +126 HP on race fuel!

The Truth About Forged Performance

This is going to be a long winded review, but my experience spans over a 22 month timeframe and I am still dealing with the repairs as I write this. I feel it is important to notate all of the details in order to properly warn my fellow GT-R owners. I would never want anyone to have to go through what I have experienced over the last couple of years.

Here are the cliff notes for anyone who doesn’t want to read the entire detailed experience” "
