B110 and B120

Which brackets you need depend on the vehicle's crossmember.

Front: 1970-1973 1200 engine tall crossmember (B110/B120)
Rear: 1974-up 1200 tall/short engine crossmember

Not only does the new-style engine have a lower right-hand mount, but the mounts are further back 35mm (~1-3/8"). These photos shows how far back:

There are TWO types of right-side brackets:
20923.jpgAlbum click to view

  • Top: original style
  • Bottom: new style for revised crossmembers
    • Allows fitment of reduction gear starters
    • Starting with 1978 B210 USA (H8500)
    • All B310 (H8500)
    • Starting with 1985 B120 JDM (G1900)

NOTE: If you mix early engine with late crosmember (or vice-versa) it will require some modifications. In this case see A-series Engine Swaps.

Early Engine Mounting

1970-1973 Datsun 1200 uses bracket that fit the early A12 engine. Note that the left-side bracket is stepped to fit the engine block.

B10 Mounts

As you can see these Datsun 1000 parts are different from newer (B110, etc) mounts.

POST qik1000 used Ford Laser mounts
Custom engine mounts to suit A14/A15. I used new ford laser upper engine mounts, which are significantly larger/stiffer than the originals. This eliminates axle tramp.

B210 crossmember change for 1978 North America

Crossmember horns are farther apart, requiring new style RH bracket
B310 uses this new spacing

B310 Mounts

The B310 insulators have a metal wrap in case the rubber breaks, the engine won't move too far.

B310 insulators have a larger studs and locating pins, but otherwise are the same dimensions as B110 mounts.

Upgraded Insulators

Puck Type

Many favor puck-style insulators, because they are readily available in polyurethane, although OEM-style new rubber makes for less vibration. Either style insulator (stock or puck) can fit stock L-type or A-type mounts.

Universal puck-style mounts, in rubber or polyurethane

These are the heavy duty engine mounts we were talking about. Broken engine mounts are a common thing in rally cars and this fixes the problem. Mounts are polyurethane and come out of a ford cortina and last for years of competition...Part number MT8156N. Kelpro make them...I usually just go to a good parts place and ask for cortina engine mounts and this is what they give me. Maybe there are two types, these are about 70mm in dia.

quote: you might want to look at the poly-urathene style mounts. I am using some of a Jag. The part number is at home. but they are heaps wider but no tallers, so they make a good direct replacement, plus they are high temp rated.

Maddat Product No - REM1200F Polyurethane Engine Mounts. Suit 1200 Reversed engine X-member (pair). New revised editions have stainless steel plates and increased re-enforcement with a slightly softer compound.
