The Nissan L-series engine (as in the 1600/510) is a good swap. Inexpensive, readily available both in USA and Australia, and these are a larger engine family than the Nissan A Engine. From L13 to L18, they are nearly identical on the outside. The L20B 2-liter engine is a tall-block variation but it still fits in the uncut Datsun 1200 sheetmetal. The Z-series Engine is closely related but has a crossflow cylinder head.
L16, L18, L20B.
NOTE: The L20B is taller though so not commonly used, but it will fit under the hood. Nissan put the L14 in the Japan-only PB110. A super-rare racing engine was the LZ20 twin-cam, fitted to 1200 racing cars.
Stubby Transmission
Using a stubby transmission will line up with the 1200 shifter hole. It is about 5 or 6 inches shorter than the more common L-engine transmissions.
- Or use a standard L-engine tranmission. The only bit of cutting wil be 1/2 of the gearstick hole but that can be welded that back in the other side to make the factory rubber shifter gasket fit back in
- Comparo: Stubby vs Regular transmission
- Notice the shifter location (top part of picture)
L20B Swap
The L20B is a 2-liter four cylinder engine. Not to be confused with the L20 six cylinder.
- no holes cut
- just panel beat the lower corners of the front of the tunnel with a hammer, as the L series is wider
- modify the engine mounts and make a crossmember
- 1200 crossmember had the mounts trimmed to an angle simular to that of an 810, then cut the 810 mounts in 1/2 to finish the job and locate the motor lower and improve the mounting angles.
- 810 oil sump is a near-perfect fit in the 1200, reshape it a little just so it will clear the crossmember, maybe 1/2cm with a hammer
- fitting the radiator in isn't a problem. you'll need a thermostat-controlled fan in front of the radiator (i.e. on the grill side)
