Description


Bore 66 mm, stroke 58 mm, Nikasil coated aluminium cylinder for all small motor housings with 125-175 cc displacement. With a standard stroke of 58 mm, you already have 200 cc displacement. And that on the small block.

Pilot times: Exhaust 190°, spill 128°, intake - diaphragm controlled, exhaust 31°.

The RB20 is nominally the smallest kit from the RB series in terms of displacement, but in terms of cylinder layout it is quite big. The diaphragm inlet with boyesen port has three boost ports. The exhaust port is one piece. This offers much more room for further tuning than the RB22 and RB25 kits. The secondary outlets limit further work on the exhaust.

The piston used is the RD piston known from the GT 186 kit. Here however with 66 mm diameter. The two steel rings are 1.2 mm thick. The compression height is 30 mm, therefore a connecting rod with 115 mm length must be installed.

Included in the scope of supply is the cylinder, cylinder head and piston, the diaphragm and the intake port.
