SOLD - Yugo 1100 Cylinder Head & 4-2-1 Exhaust Manifold/Downpipe

Jeff Stich

True Classic
SOLD - Used Yugo 1100 carbed cylinder head assembly. Good condition overall, includes all valves/springs/keepers, cam housing mounting bolts/washers, intake/exhaust manifold mounting studs/nuts/washers, thermostat housing mounting studs/nuts/washers, 10mm head bolts/washers & the coolant temp sensor, as shown. Cylinder head casting is type 128A000, number 4469750. Casting date stamp shows July 1986.
This head is often used as a budget-conscious way to bump up the compression ratio on USA 128's & X1/9's, since there is no large "decompression ring" around the combustion chamber like on the USA-model Fiat heads. Gives a bit more torque in the lower-rpm powerband, but less in the top-rpm area due to its smaller valve sizes (compared to 1300/1500 heads). Thus, good for the hot street/canyon driver or Autocross car, but probably not for the racetrack.

SOLD - Used Yugo 4-2-1 exhaust manifold/downpipe assembly. Good condition, no cracks. Can be used on 128's & X1/9's as part of a good-flowing custom exhaust system (the lower short, curved pipe section can be rotated as needed). Sold as a complete unit (will not sell parts separately).

SOLD - Used Yugo Bosch electronic ignition distributor, wiring harness & control module/heatsink assembly. Probably the simplest & most compact electronic ignition available for these engines; mount the module/heatsink on the firewall, connect the red/green wires to the coil & black wire to ground, & you're done! Includes everything shown.
