• HPF (Horsepower Freaks) Targets 1100 rwhp with their Stage 5 BMW E46 M3 S54 turbo kit

      We just ordered up the turbo for our stage 5 turbo kit. We are going to go with the Garrett GTX4508R with the Tial V-Band Exhaust Housing and 1.0 A/R. With our extreme internals and sleeved blocks, we feel this turbo will suit nicely. We will create the tunes on both the AEM platform and the ProEFI platform. Part of our turbo manifold is already completed, but since we changed turbos, we have to alter the design slightly for the larger Garrett GTX4508R. We hope to have results later this month.

      Here's a list of the Garrett product lineup:

        Gnarly. Don't think I'll go higher then 2.5. After I take of some other stuff I would like to switch to pro efi for some e85 action.

        That's insane. I'm guessing the suspension will have to undergo some changes also, in order to support that ridiculous power.

        That is awesome. Great route to take HPF, need to make the car more track driven and less lag.

        It will most likely be at least 50k. When you add that to the price of the car, there are much better options.

        I think this is a HPF internally developed package.

        You could have gotten the 1100whp with the gtx4202r with less lag. Do you sell precision turbos?

        the lag can be controlled by choosing the correct turbine housing dont you think? by the looks of it though, its already chosen.
