Hi Matt, The R series engine was fitted to the following vehicles :-
Bluebird SSS RL411
Nissan Silvia CSP311
Datsun Homer truck T641
Several models of Datsun Forklifts
The Silvia and Bluebird SSS engines are basically the same as the SP311.
The commercial version of the engines all have cast iron heads with
smaller intake and exhaust ports, lower compression (8.0:1), smaller valve
diameters and a different cam grind. They also have a pressed steel tappet
cover and timing chain case instead of cast alloy.
Roadster engines up to eng.#40000 have a cast alloy head, 3 bearing
crankshaft and a breather pipe decending from the top of the block at the
#4 cyl. end of the block. (this is obscured by the manifolds) >From
#40001 onwards they have an alloy head, 5 bearing crank and no breather
pipe. Engines before #02312 have an oil filter with a replacable element,
after that they had a cartdidge oil filter.
To check out what engine goes in which car you can check out the
"Specifications" page on the Early Datsun homepage.
