• HPF (Horsepower Freaks) BMW N54 single turbo manifold pictures and details

      We are finishing up the turbo manifold right now. The pictures below were taken a week ago. The head flange is quite complicated with how the turbo manifold seals to the head, but it is also quite ingenious. There are two ports leaving the collector to the wastegate which is a Tial 44mm VBand to ensure boost control is easily maintained. This turbo manifold fits all Precision T4 Performance turbos from a 67 to a 76. We will sell them separately for those that want to build their own custom turbo kit, but will also sell all the hardware to complete the turbo system.

        I just copy/pasted what Chris wrote on e90. I would also be interested in how they plan to run the external w/g. All the other manis (from other companies) had some pretty crazy setups so I guess we'll need to wait for Chris or a rep from hpf to show us more pics. If they choose to post more on e90 then I will bring it over here.
