Datsun motor mounts

[Datsunblue72]

Hi I have a Datsun 510 1972 blue bird 

we did L20B motor swap and I would like to know what brackets and where I can get motor mount brackets that fit it right

You need the brackets from the car, not from the motor.

Yes, so use the rubber mounts and brackets from the L16 original engine if you have them.

 

It will sit higher since the L20B is taller, so understand that will be normal.

You need the stock L-16 mounts or the valve cover may hit the hood.

I think it will simply bolt right onto the L16 brackets and isolators and fit. Lots of people have swapped L20Bs and you never hear much about the fit.

 

The right engine bracket is unique to the 510 however the left one is also shared with the 521.

 

The L20-B is exactly 2cm or 3/4" taller than the L16/18 so assuming you had an L16 originally, just fit the L20B onto the brackets and rubber isolators.  Put a lump of clay on the valve cover (highest point?) or maybe the air filter and slowly close the hood.  I wouldn't buy rubber isolators as they are often thicker than stock

 

In a pinch, oval the bottoms of the two pair of holes on the engine brackets. This will allow the engine to sit slightly lower. Look at your steering cross rod through the full steering range and front cross member for enough clearance to allow this.
