• PAW Motorsport offers N54 ported/polished cylinder head upgrade - $3995

      PAW Motorsport is offering a cylinder head upgrade for N54 based BMW vehicles. There is a substantial gain in port flow velocity without a sacrifice in low lift situations. Flowbench charts show an increase of about 35% with gains from 161 cfm to 227 cfm. Both intake and exhaust ports have been ported and polished along with modified intake and exhaust valves. The claimed power gains with the head alone are in the 40 hp range. Charts and pictures are below.

      Expect before and after results on a PAW DCT N54 project car in the next few weeks. For those interested in this upgrade there is a core charge in the $2800 range which obviously is refunded when the core is received.

        Are you letting him borrow your RB's? How does that work, why is he sending you stockers?

        Just heard from someone that the PAW guys installed and tested the head on stock boost and gained 15whp and that they were working on tuning .. Sounds promising but can we really expect up to 100hp as claimed with just the head change on RB turbos is what I'd really like to know..

        here's what i got:

        PAW are still working on the head, they recently installed it on their own car and are tuning it, so far I think they picked up like 15whp over stock with just the heads, they are doing more testing with catless dps and dci.
        sucks that we're getting this info from others and not paw themselves...

        We'll see what they can really do at higher boost.
