4G93T GSR First Generation Differentiation

Since Malaysia government had changed the rules and regulation for engine conversion, which all Proton cars except Proton Perdana cannot convert to 2.0L engine, the Mitsubishi Lancer GSR 4G93T is one of the highest horsepower turbo engine that can fit into Proton cars (only applicable for those who wish to register their car to JPJ and legally on the road). From the topic, it is clearly shows that this is the first generation 4G93T GSR 1.8L from the Mitsubishi Lancer.

There are two types of engine specification throughout the entire life of the Mitsubishi 4G93T first generation engine. There are the normal version which capable to produce approximately 190hp and the 4G93T RS from the wagon also known as Libero in Malaysia here which able to produce approximately 210hp.


Below are some of the specification of the GSR 1.8L RS.
GSR 1.8RS:
1. Body: wagon
2. HP: 210bph on flywheel

GSR 1.8RS specs.:

Displacement : 1834 cc
Engine model : 4G93T (turbo)
Max.power (Net),: 150.78kw(205PS)/ 6000rpm
Max.torque(Net): 28.0 kg*m (274.59 N*m) / 3000 rpm

Engine type Water cooling serial 4 cylinder DOHC16 valve IC turbo
Engine information :
Fuel system ECI multiple (electrically controlled gasoline injection)
Turbocharger Turbo with intercooler
Fuel type Unleaded premium gasoline
LEV system (Low emission vehicle) No

Compression ratio : 8.5
Bore : 81mm
Stroke : 89mm
