Exhaust Manifold

1978-1980 exhaust ports are round
All other years are square
A square manifold will work on a round port head (barely) better than the other way around.

L20B manifolde are 4 into 1 with a single large round connection to the down pipe
Others are 4 into 2, with two outlets into a twin-pipe down pipe

All 1975-1977 L20B exhaust manifolds are also bolted together with the intake manifold (heat riser type)

Standard L16/L18 cast iron extractor is 4-into-2 and have an exhaust shop make up a 2-into-1 exhaust pipe, tuned to whatever RPM length you want to rev your engine.

Thermostat Housing

L20B thermostat housing changed three times due to incorrect readings on the temperature gauge.

The improved version is a 3-bolt outlet & gasket, from May 1978.

The 3-bolt housing is the best one. The dealers used to put it on L20Bs that were marginally overheating and it fixed the problem. Of course you have to change both the housing and the outlet both.

The last time Nissan revised the L20B thermostat housing they increased the outlet to a larger diameter, and used larger hoses. This was to (yet again) prevent overheating issues. It seems to have worked.

Clutch

L Engine transmissions use a hydraulic clutch. For LHD 1200s, just connect the existing hose to the new transmission.

Changing the clutch over to hydraulic from the Datsun 1200 cable system. You can use a Clutch Master Cylinder from Stanza A10. Put a hole through the firewall with a hole saw and bolt it up. Its very close to the brake master cylinder. Straighten the clutch pedal at the top so that it pivots correctly.

Flywheels

When purchasing the engine, get the matching flywheel with it. Some L-series engines use a crank with five bolts for the flywheel, but most have six bolts.

Best to get the matching clutch assy and be sure to get tne matching release bearing sleeve.
