rb20/25 combo

[Roy]

The combusiton chambers will need attention, as dont forget by using the 4AGZE pistons you are increasing the bore.

You will need a head gasket to suit... the only other thing i would perhaps look at in addition as a minimum requirement would be some good rod bolts and shot peening the std rods along with the balancing/blueprinting.

So std the RB20 has (bore x stroke) 78 x 69.7 = 1998cc

With the RB25 crank and 4AGZE pistons you will have 81 x 71.7 = 2216cc

Sounds like a goer
