HPF (Horsepower Freaks) Targets 1100 rwhp with their Stage 5 BMW E46 M3 S54 turbo kit
Published on 07-01-2011 06:22 PM
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:
