Exhaust Manifold

• N58 exhaust ports are round (L18P Japan, 1978-1980 North America)

• All others are square

• A square manifold will work on a round port head (barely) better than the other way around.

• Some late manifolds are 4 into 1 with a single large round connection to the down pipe

• Most others are 4 into 2, with two outlets into a twin-pipe down pipe

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.

• fits 1200

• lasts forever

• no exhaust leaks

• quiet

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.

The big hose goes down to the cool part of the radiator (the bottom).

The small hose going up leads to the thermostat housing on the other side of the engine

13049-21001 INLET-water PB110 13049-U0100 WATER-INLET 510.USA 27061-21000 CONNECTOR 2 WAY

The 2-way connector: leads up the intake manifold on the other side of the engine. Some engines, this tees off with a "bypass hose" that goes to the thermostat housing. Some L engines do not have the bypass hose.

For the 510, the rear outlet is capped. For the PB110 it is connected to the heater outlet hose.

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.
