Category: PB110

The Datsun PB110 model line was added March 1971 and was named the Sunny Excellent 1400 (サニー エケセレント 1400). It featured a larger overhead cam engine and modified front sheet metal styling. It is also called the "Sunny Long-nose" (サニー ロング ノーズ) because — although engine bay seems to be the same size as a B110 — the guards and bonnet of the PB110 are longer in the front to make the car feel bigger. The wheelbase is 40mm longer (less than 2 inches) but the PB110 overall is more than 5 inches longer. Most components of the PB110 are the same as B110, including 12" tires and same dashboards.



Our beloved "Datsun 1200" is Nissan body code B110, equipped with the 1200cc A12 pushrod engine. This is also known as the Datsun Sunny 1200. In Japan however, there was an upscale derivative of the B110, the Sunny Excellent -- body code PB110. The P apparently stands for "bigger engine". Yes, the Excellent was fitted with the L-series Overhead Cam (OHC) engine, the same type of engine fitted to the bigger Datsun vehicles.

DX and GL models had a single-carb engine, while the GX had dual sidedraft carburetors (GX originally meant GL with Twin Carbs).

Dashboard And Steering Wheel

1971 | 1972
2129.jpgAlbum click to view 460.jpgAlbum click to view

* Early GX dash (same style as B110, but with woodgrain accents)
* Three-spoke GX wheel, spokes have single slots
* Deluxe uses same steering wheel as Standard B110
* GL uses 3-spoke steering wheel
* GX has standard 3-spoke 'large-horn button' wheel with "GX" emblem in center
  Each spoke has two long slots.

The Late PB110 instrument cluster is the same as Datsun 1200 "Late", but the dashpad is different as is the glovebox:

Later 'hooded' dash. Picture clearly shows the concave profile of the instrument cluster. (aftermarket seat color, shift knob, equalizer). Judging by the wood-grain dash and steering wheel style, this is a GL model.

How Different From B110

How different is the PB110 from B110?

* Passenger compartment
  * Doors
  * Roof
* Firewall
* Rear quarters & boot lid
* Front fenders incorporate corner lamps
* Wheelbase +40 mm
* Radiator Core Support appears to be only +40 mm forward
* Bonnet is longer, extended further beyond core support

Discussion: POST PB110 (Sunny Excellent) vs. B110 (Sunny)

So the engine does not appear to be farther forward, but actually as far back as in B110. Being "set back" a little compared to the front wheels may have contributed to good handling even though the L14 engine is much heavier than A12 engine. The extra 40 mm is probably used for the slight length difference of the L14 and the extra thickness of the 510-type radiator.

In front of the radiator core support and bonnet sticks out about 5 inches longer than B110. 40mm in the wheelbase, and 130mm in the nose.

The extra length is all forward of the windshield:

Fenders appear to be same length & height, but 1400 wheel arch is slightly larger and doesn't go as far forward.
