Mod A Mini R53 big valve head conversion

Mod A Mini R53 big valve head conversion.


Running 31mm inlet and 25.3mm exhaust valves. The cylinder head is extensively ported. The valve seats are then recut to the maximum diameter of the working face on the valve using a specially formulated 3 angle cutter. Using the multi-angle cut allows for a smoother passing of the air and fuel mixture into the bowl. CC chambers are check to ensure there are no discrepancies. The cylinder head is then refaced to ensure flatness.


Once the cleaning and preparations are finished we then rebuild the head using new victor reinz valve stem oil seals. Super tech springs and retainers are available upon request.

Mod A mini Fast road cylinder head is also available. They are the same as above except for the enlarged inlet and exhaust valves. Again Supertech springs and retainers are available upon request.

 

This is a fantastic mod to unlock some extra ponies for the engine! the heads on the R53 are a known restriction. If you want to make big power, this kit is a must!

 

NOTE: Please allow up to 4 weeks for delivery, you will need to supply the R53 Cylinder Head to be reworked. We can supply a head for you, if required, please message us beforehand.
