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)

    Used with any high performance Datsun engine utilizing an SSS/SU or Mikuni/Solex intake manifold. Specifications are the same as 11041-U8880 except that intake port diameter is 1.5".
  • 99996-D1162 COMPETITION CYLINDER HEAD
    Recommended for racing purposes only. Completely ported, polished and fitted with 44mm/1.73" intake valve seats and 35mm/1.38" exhaust valve seats.
  • 99996-D1161 COMPETITION CYLINDER HEAD (W/VALVES)
    th_11041-D1161.jpg
    Recommended for racing purposes only. Specifications are the same as 11041-D1162 except that competition valves are fitted.
  • F.I.A. CYLINDER HEAD ASSY (LATE STYLE)
    This later style F.I.A. cylinder head incorporates several improvemnts over the earlier style head (11041-22010). Among them are an improved port design for better flow and the ability to utilize many stock L-series cylinder head component pieces. The 50mm Mikuni/Solex induction system listed is designed to be sued only with the 11041-N7120 cylinder head assembly. Definitely not recommended for street-driven vehicles.

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.

11060-Y7010 OUTLET-WATER

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.
