Two-cylinder engines Seat / Fiat Mcj 8 valves ...

Phase 1 or medium preparation: Cylinder head lux, weber idf 44, Mcj exhaust manifolds, 85mm high compression pistons, phase 1 camshafts, crankshaft tears and partitioned winder housing. estimated power between 143 and 147 hp.

 

Phase 2: 45/40 valves, flowmeter, weber DCOE 45, Mcj manifolds, forged pistons 85 mm compression 11.4 / 1, guy Croft 3D and 3A camshafts, crankshaft tears and partitioned winged sump. estimated power between 178 and 185 hp. optional forged crankshaft.

Phase 3: 45/40 valves, flowmeter, weber DCOE 45, Mcj manifolds, forged pistons 85 mm compression 11.4 / 1, guy Croft 3D and 5A camshafts, crankshaft tears, GC dry sump, estimated power between 195 and 200 cv. Forged crankshaft optional and recommended.

Phase 4 : 45/40 valves, flowmeter, weber DCOE 48, Mcj manifolds, forged pistons 85 mm compression 11.4 / 1, guy Croft 3D and 5A camshafts, crankshaft tears, Guy Croft dry sump, 98 mm forged crankshaft, Displacement 2,224.40 cc. , the biggest advantage of this type of engine is the average speed, which involves a longer duration and less maintenance of the engine. power estimated from 200 to 210 hp but incomparable performance and power in medium regimes with phase 3.

Phase 5:   45/40 valves, flowmeter, 48 carburetor simulation injection, DTA control unit, Mcj manifolds, forged pistons 85 mm compression 12.7 / 1, Guy Croft 3D and 5A camshafts, Guy Croft dry sump, 98 mm forged crankshaft, 2,224 displacement , 40 cc. , the greatest advantage of this type of motor is the average speed power which involves a longer duration and less maintenance of the motor when working at lower speeds, expected power between 212 and 220 hp, the expected increase in power with respect to the phase 4 is due to the change from injection carburetion and compression increase from 11.4 / 1 to 12.7 / 1 for which we will use Sunoco 105 octane gasoline in the first map and in the second ethanol map, we are manufacturing one For our Seat 124, soon we will have the real damage of this engine, we have high hopes for this engine since it will possibly be one of the 8 most powerful valves with the best power curve ever manufactured.

Two-cylinder engines Seat / Fiat Mcj 16 valves ...

Phase 1: Lancia Integrale cylinder head rotated 180º to maintain original Seat / Fiat position, flowmeter, weber dcoe 45, Mcj exhaust manifolds, forged 85mm high compression pistons, 11.4 / 1 compression, forged connecting rods, Guy Croft phase camshafts 1, Crankshaft Tears and Winged Septum Crankcase. power between 200 and 207 hp.

 

Phase 2: Cylinder lancia Integrale g irada 180 to maintain original position Seat / Fiat, flowmetry, weber DECO 48, exhaust manifolds Mcj, high compression forged pistons 85 mm, compression 11,4 / 1, forged connecting rods, camshafts Guy Croft phase 2, Guy Croft dry sump. power between 238 and 245 hp.

Phase 3: Cylinder lancia Integrale g irada 180 to maintain original position Seat / Fiat, flowmetry, injection or carburetion simulation Jenvey throttle bodies 48, DTA unit, Manifolds Mcj, forged pistons 85 mm compression 11,4 / 1, Camshafts Guy Croft phase 2, Guy Croft dry sump, 98 mm forged crankshaft, 2,224.40 cc displacement, the greatest advantage of this type of engine is the medium revs power which involves a longer life and less engine maintenance. Power between 245 and 250 hp, but the behavior and power in medium regimes with phase 2 are incomparable.

Phase 4:   Lancia butt Integrale g irada 180 to maintain original position Seat / Fiat, flowmetry, Jenvey throttle bodies 50, ECU Life Racing or Ms. Marelli, Manifolds Mcj, forged pistons 85 mm, compression 12,7 / 1, Camshafts Mcj Abarth phase 3, Guy Croft dry sump, forged crankshaft 98 mm, displacement 2,224.40 cc, the expected increase in power compared to phase 3 is due to the change of 48 to 50 mm in the injection bodies and the compression increase of 11 , 4/1 to 12,7 / 1 for which we will use Sunoco gasoline of 105 octane in the first map and in the second ethanol map, this engine can reach 291 hp at 8250 rpm, but we use settings of 7500 rpm with a power of 265 hp or maximum 8000 rpm with a power of 284 hp.
