2007-2011 BMW N54 HIGH BOOST MODIFICATION

*** CAUTION! MANY OF OUR CUSTOMERS HAVE VERY SUCCESSFULLY ACHIEVED 1000 HP PLUS IN THEIR N54 BY GENERATING EXTREME BOOST PRESSURES. OUR HEAD BOLT THREAD INSERTS ALONG WITH ARP® STUDS HAVE BEEN KEY TO KEEPING THE HEAD FROM LIFTING UNDER THESE EXTREME PRESSURES. BUT PLEASE UNDERSTAND, IF YOU ARE CONVERTING THE FOUR CORNER HOLES TO A THREAD SIZE OTHER THAN THE FACTORY THREAD SIZE, YOU ARE DOING THIS AT YOUR OWN RISK. WE ARE NOT RESPONSIBLE OR LIABLE FOR ANY CATASTROPHIC FAILURES FROM DOING THESE TYPES OF MODIFICATIONS.

Thank you!


For those interested in doing this type of modification, a good customer of mine allowed me to share the below

links to his very well done YouTube video’s.

“I bought a N54 kit from you in March 2024. I’m very happy with how they work. I’ve done over 100 passes in the worlds fastest twin turbo N54 and no sign of the head lifting (video links below) ”
