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.

Trim Levels: DX, GL and GX

This outlines the various trim levels the Coupe was available in: GX, GL and DX. The writing above '1400' phonetically spells out the english word "Excellent" in japanese katakana writing: e-ku-se-re-n-to.

The same trim levels were offered for the Coupe and for the 4-door Sedan:

* GL and GX trim used wood grain on lower half of dash
* 1972 Facelift dash has hooded gauges. The hood reduces glare. 
  (NOTE: this is the same dashboard as in regular 1972 Datsun 1200s)
* Excellents came with extended color choices for carpeting


Dash is same as 1200

Optional Equipment


The Sunny Excellent PB110 was fitted with 1400cc L14 engine, a smaller-displacement version of the L16 fitted to the Datsun 1600. This is an overhead cam engine. Both a single carb and dual-carb engine was available. Top speed was 155kmh, up 5km from the Datsun 1200.

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 2129 460.jpgbrochure

* 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:

3099.jpgAlbum 3099 11130.jpgAlbum 11130

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.
174_580aee57e262a.jpgPost 482037

The extra length is all forward of the windshield:
18751.jpgAlbum 18751

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