How much horsepower does a Mitsubishi 4G94 have?
You can choose the forced induction way and get the same 200 – 250 horsepower, but using a Mitsubishi Evolution TD05H-16G turbocharger and low boost pressure, because stock internals of your 4G94 are not too strong. They should withstand the boost pressure of approximately 0.5 – 0.6 bar. This will give you about 200 HP.
How tall is the cylinder block on a Mitsubishi 4G94?
The engineers took a cast-iron 4G93 cylinder block and did a good job with it. They increased the deck height to 231.3 mm and increased the cylinder bore from 81 mm to 81.5 mm. Into this block, they installed a 95.8 mm long-stroke crankshaft, 152.9 mm conrods, and 81.5 mm pistons with a compression height of 30.4 mm.
What do you need to make a 4G92 engine?
You will also have to buy 4G92 pistons, ACL main and rod bearings, a 4G93E oil pump, a MIVEC ignition and fuel systems, a head gasket, head bolts, a 7M-GTE timing belt, and a 4G92 harness. This will immediately give you 200 HP. Need more?
How big are the intake valves on a Mitsubishi 4G94?
The size of intake valves is 32 mm, of exhaust valves — 29 mm. A multi-point fuel injection system was used for this head. There was yet another version with a DOHC head and two camshafts. Their duration was 246/250 degrees.
What is the displacement of a 4G93 engine?
All this results in the displacement of 1.83 liters. You can buy cars with various modifications of 4G93 cylinder heads. The simplest is the SOHC 16 valve head, which is installed with carburetor injection (101 HP) or multipoint fuel injection MPI (117 HP). The 240/252 deg camshaft is found here.
What are the problems with the Mitsubishi 4G93 engine?
This problem is usually found in GDI engines, the reason is clogged high-pressure fuel pump, and it should be cleaned. The second reason is the dirty throttle body, clean it. The third reason is the idle air control valve, try to replace it. However, that’s not all, the 4G93 GDI engines have issues with the EGR valve.
Why is my GDI 4G93 engine not idle?
Idle problems on the GDI-engine is in several cases due to an permanent magnet coming loose inside the electromagnet-motor on the throttle body. The loose magnet gets in the way and the flow damper can’t work normally.
Is the EGR valve on the 4G93 GDI bad?
However, that’s not all, the 4G93 GDI engines have issues with the EGR valve. For this reason, the intake manifold is constantly clogged and needs regular cleaning.
