    • 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.

        oh, i dunno how that went, the guy sent me bad 135 turbos, matt saw that, 1 they were 135, and 2 they were $#@!ed, and we sent them back, i never bothered to ask anything more. he is in DC/MD though, i believe he was the 5th proceder i was talking about elsewhere, and was rebuilding his motor at the time.. im sure if anything good came of it, you guys would all know by now
