New for 2023 are our 58mm stock manifold turbos! These feature the same great parts and workmanship that have made our spec1000 and 1200 turbos a staple option for this platform in only 2 short years of production.

The limitations of the spec1200 turbo has always been the stock compressor cover, when moving up to the 58mm compressor, we needed to increase the flow potential of the compressor cover to allow that 58mm wheel to breath its full potential into our beloved VR38s.

To match the increased air charge, we upgraded the turbine from a 55mm to a whopping 62mm (35r equivalent) turbine capable of exhausting the gasses and decreasing E-MAP as much as possible on a stock manifold/turbofold.

These 58/62mm variants have made over 1300whp and are capable of mid 3 second 60-130 times.

Each kit includes Turbosmart IWG75 actuators and 3.5″ aluminum inlets. Necessary coolant and oil lines are also included in the kit to make install a breeze.

Cores are to be returned within 8 weeks of your Spec turbos shipping. For longer intervals please email sales@rampagefab.com
