Nissan Skyline model R31 was built in Japan 8508-9005. It was fitted with a Four Cylinder CA engine, or six-cylinder RB engines, or a Diesel. Australia-built R31 1986-1990 was sold as Skyline (six-cylinder) or Pintara (four-cylinder). Some parts can be used, or modified for use, on a Datsun 1200.

Front Brakes

R31 featured 4-lug x 114.3 PCD wheels.

* R31 integrated hub
* R31 disc-over-hub RB20DT.(K+4K) 4-lug 40206-59S01 <> 40206-59S02

250 mm

Standard wheel on R31 is 14". Shouldn't be any problem running 14" wheels over these brakes. A few 13" alloys will fit, though no steel 13" will fit, even with grinding.

integrated-hub type

Though these are relatively small brakes, they are vented so will stand up to repeated braking, or mountain driving. The caliper bolts are 3.5 inch apart, which is not a common dimension for upgrading the calipers. Also see S13 Brakes for another 250mm brake swap.

These require a AUS R31 strut or a JAP R31 non-RB20DET strut (e.g. Japan HR31, FR31 and SR31 have these brakes -- only the RR31 turbo has the larger brakes).

274 mm

The large R31 floating rotor 274 mm brakes require a 15" wheel. Stock was 6x15".

disc-over-hub type (similar to S13 Brakes)

These require a Japan RB20DET strut with its 100mm caliper spacing, although theoretically other Nissan 100mm struts might possibly be used with caliper spacers for the hub depth difference. Best to get the strut & brakes as an assembly.

Rear Brakes

Pintara rear discs in the 259 mm option may be used on the front of Datsun 1000.

Strut

R31 uses a standard Nissan 2.0" strut, so will bolt to the usual SAP.

Some say you need to buy/fabricate a spacer with shear ring as the locating hole is a different size where it meets the steering arm. R31 struts have a 54mm hole on the bottom which matches a 54 mm lip on the R31 steering arm. The W50 steering arms have a 40mm hole but no protruding lip. However, stock A10/B310 struts do not have shear relief so it may not be necessary.

Of course you need to fit stock 1200 springs as R31 spring are large diameter.

The R31 strut tubes are similar to 280Z struts in that they are short right from the factory. The advantage is that R31 has the strut tube offset to the inside, allowing slightly wider tires inside the wheelwell. This is countered by a short-offset hub, so choosing an appropriate wheel offset is still required. They are low-scrub struts, keeping SAI to a minimum.

Datsport sells a performance version with adjustable small-diameter coilovers. http://www.datsport.com/strut-dsk250C.html
