              🚨New from KT4!🚨 We have developed this adapter piece in our efforts to bring down the costs on 
              our Volvo 3.0L T6 Big Turbo Kits to make them more affordable for the Volvo community. Now 3.0L T6
              owners can keep their factory manifold and adapt it to the after market Borg Warner EFR Turbo 
              charger with absolutely NO modifications necessary.

                                               

As you can see here, the turbo adapter is a seamless fit that allows you to connect the racing Borg Warner EFR Turbo to your factory exhaust manifold with the factory manifold bolts.

Power expectations: 

  • If you want to use the kit on your Volvo 3.0L T6 without upgrading the engine itself, then you would have run a lower boost pressure (13-17 psi) and your power expectations should be between 360-390 whp.
  • With forged connecting rods and upgraded cam installed, you can expect to make 450-520 whp. (@ 18-28 psi)

*Our goal is to make Volvo performance as affordable as possible, this pricing is an estimate and may change depending on whether we add standard items to the kit as R&D continues. Forged connecting rods and pistons will be available to those wanting to take their Polestar to the extreme. Cost for the forged connecting rods is $120/rod and the cost of the forged pistons for the Volvo 3.0L T6 is $95/piston. The forged connecting rods are the only engine internals that MUST be upgraded in order to achieve 400whp+ on the dyno with the Volvo 3.0L T6. Pistons will also be available for those looking for more reliability.

  • KT4 Performance recommends upgrading the factory fuel injectors to at least 755cc for stock block applications (but is not required) and 850cc for built block applications (required).

As far as the transmission is concerned, we are currently working on developing this upgrade as well. By increasing the surface area of the clutch within the factory transmission, improving the flow of the factory valve body to increase the overall line pressure and upgrading the factory transmission cooler, we can increase the overall torque output by up to 50%, which is roughly 600 lbs\ft. If you plan to use your factory transmission with the big turbo kit, that is completely okay, but you must be careful to avoid hard launches as this may cause the transmission to leak and slip as the single clutch struggles to grip with the massive amounts of torque from your new high performance set up. Shifts between gears once the car is rolling are no issue for the Volvo, at WOT on the highway the TF-80SC is able to hold up between higher gear shifts. It only begins to have problems when it is being launched hard and often.

An excellent fit for use in single turbo applications for the 400-600hp range (up to 2.6L), or as twin turbo applications 800-1200+hp. Ceramic Ball Bearing only, watercooling recommended.
