Drivetrain RMW Big Valve R56 cylinder head
#1
RMW Big Valve R56 cylinder head
New guides, seals and CNC porting
I worked with Supertech to develop the valvetrain with beehive springs and titanium retainers
Custom oversized valves for intake/exhaust with inconel material which can withstand 2000 deg F
each head is surfaced flat and ready to install
Our heads are on many cars around the world
Only head out there with actual head flow numbers. Ask anyone selling you a head for theirs. Know what you are buying
Pricing is $2550 plus a good head core
Oversized intake and exhaust valves with Beehive springs good to 35psi and 9200rpms! Single groove keepers, titanium retainers are standard. New valve guides, custom valve job and superior performance in a cylinder head

at this time I don't have a cam manufacturer to give a rec to. Newman who grinds all of our cams for the 1st gen cars was working on getting blanks for these but at the current time I believe they don't have anything. I'll check tomorrow.

Love IT!! Show me more!!
Q - any chance of port matching big plenum R53 intake mani to this head? I want to ditch the OEM plastic manifold and the R53 mani looks like the (almost) perfect way to add port injection at the same time. There are few/no options available for this route on R56 without fab it looks like though.. which is why i ask.

I'm shocked more people haven't built something for the 2nd gen already. Me, personally I won't do anything for the car until there is a proper solution for the tuning. I constantly get people coming to me asking for a stand alone because their cars don't run right with the bigger turbo setups of what's offered out there. By the number of them that come for engine rebuilds I would have to agree

Does this mean the days of piston #3 failures are coming to an end? I see rmw has pistons/rods now. I've held off on building a R56 due to the tuning/failure issues. SCCA classes them so much better for autocross & TT, and the platform is faster on the track.
I keep resisting switching but maybe there's less reason not to?

obviously good rods/pistons will make a difference. I'm the only one out there to address the oil consumption issue by designing a proper ring package for the pistons. I have custom rings made by Mahle Motorsports division.
