    • 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.

        Let me get this right it's 3995 then when you send in your head it's 2800? Or 3995+ 2800 core charge/ refundable.. The second one sounds more like it
        Second is correct.

        Good question, would like to know as well. The head can be pulled without pulling the motor right?

        correct me if I'm wrong but I think labor should be around 20 hours...think books quote 18.8 with all the little bmw special tools so I guess if you don't have them it could take quite a bit longer

To me it seems that the exhaust side is still restrictive even after upgrading the exhaust valves. However to be sure, we would need to have two heads with different porting strategies regarding intake/exhaust port flows and compare the results in dyno or standing mile.
        just look at the flow increase of the intake and exhaust. Pretty clear where the biggest restriction was . Click here to enlarge

        BMW also says turbos should take ~18 hours? My tech did mine in 9 or 10 taking his time..

        They quote such long hours so they can make more money... Plus the techs get paid for the quoted time it's suppose to take- so they can do 80 hours of quoted work time in a 40 hour work week

        So then how many hours should it be? 10?

        Does the motor need to be pulled?

        I doubt this would make any gain without a turbo upgrade. It's really cool to see tho. I personally would hold off on such a mod until a reliable dual gt25/8 or single gt35 upgrade is available. You'd have to be there before $4K for 40 hp would be worth it. Can't wait to see the results.

        We'll know more when we see the results paired with RB's which is what one person is getting. Expect those results in the next few weeks Click here to enlarge

        I would have to ask a friend or two at BMW but Im pretty sure this would be 20 hours or so. Both turbos and the intake manifold have to come out, then the head comes off. Lining the timing chain up is the hardest part, and then assembly of all the injectors/ fuel rail and plugs and coils. And the first time around I am NOT rushing to 'beat the clock' on this one.

        I like how this thread on the other forum consisted of nothing important. People bashing sticky or 'too expensive, this should cost $1500, I'll buy something else instead'

        I get sick of the bull$#@! sometimes, excuse my french.

        If they hate then let them hate and watch the money pile up.

        I'm glad there is a place to escape all the kids, real info and real enthusiasts (and real vendors Click here to enlarge ) are all here, so who cares.

        20 hours of labor is rough as this definitely is not cheap but we are all happy this is available obviously. No need to complain about the price, if you don't like it don't buy it. I doubt any of the kids leasing are in the market anyway.

        If the turbos and the intake manifold have to come off then I would say pairing this with an RB upgrade makes a lot of sense, doesn't it?

        Any real market, people will pay for good labor. At my former shop people dropped 10-20k without even thinking twice. All they wanted to see what a breakdown of what was getting done, how much each part of the work cost and an explanation. Good work comes at a price, and unfortunatley BMW owners are in the top ranks of trying to justify a price to anything. It makes me want to get out of this business and go back to building Porsches and seeing real results on the track, not the same repeated dynos of 'I have FBOs and I only made xxx, why is my dyno low'.

        What about 0-60 Motorsports? He has some crazy work done over there, and you dont see people saying he cost too much right?

        And yes doing this with a turbo upgrade would be beneficial. You would save on the additional labor later on to do the turbos.

        Please don't group everybody together. Unfortunately, you have to deal with a lot of kids with leased cars who want everything for free. You get kids who will play tuners against each other to try and get a free N54 tune as sad and pathetic as that is.

        I won't even say what I drop on my car... and all cash. I drop it off, do the work, end of story.

        He doesn't deal with the 16-22 demographic. People pay for quality work.

        That is exactly what I was thinking. I think this combo might prove to be popular.

        I agree with this for the most part. I do think however that some of the prices of the aftermarket parts are ridiculous though and I believe that results from the BMW label. An exhaust, for example, shouldn't cost $2K on a car that BMW made 250,000 of.

        Yeah my apologies on that one. I wasnt trying to group everyone in on that comment but i think the people who actually invest the time and money into their cars would see where im coming from and know they arent included in it. But thank you for clearing it up.

        Sorry just ranting a bit. Had several customers call me today and try to get me to go down in price on work, or say 'xyz shop has them for this much, and they are charging me abc to do it'. One customer doesnt bother me but when you get 4-5 people in a row it gets a bit annoying. Still working on the customer relations end of things.

        True, we often get a BMW tax but on this part until someone demonstrates offering better for less this is the best value available.

        I'm just happy the N54 guys have a solid head option now. It won't be for everyone but the market is certainly better with this head and PAW Motorsports involvement in particular.

        Any shop has to survive on the profit generated by this if that is all they make. Price of steel these days isnt cheap. For cheaper end 304 i paid 40-50 a bend. Plus flanges, mufflers, fabricating the jig and paying the welders to do their skills (most of which get paid very good for) and then the R&D that goes into making each one sound like it does. At the end of the day you are making what, 400 bucks profit? Do you think that is a lot?

        What if you sold two exhaust systems a week. That is 800 bucks. Now lets say you have a house, car, wife and kids. You think 800 a week is gonna cut it? I make more than that and its still tough. And im not even out of my house!

        Anyways enough talking business economics...

        Seen this head in person, looks very promising!

        I met them about 2-3 years ago, great guys, very honest and to the point and they know what they're doing.

        Ive over heard them talking about more than just what you see here eventually!

        Exactly, they have some big plans in the works for multiple platforms.
