4g92 mivec manual

It uses a timing belt, you have to replace it after every 60, miles 90, km , otherwise, it will break and the valves will bend. Here are other engines of the 4G9 series that are very similar to 4G 1. Knocks in the engine. Check the hydraulic tappets, if necessary, replace them. Usually, the problem is in these components. Increased oil consumption. Do not be surprised, your car is quite old.

In this case, an overhaul is required. Idle problem. Check all of these, you will probably find the reason. Summing up, it is a pretty good engine with high reliability that can run more than , miles , km. First, I want to tell owners of 4G92 SOHC, listen, guys, your head is good for nothing, and you just waste your time working with it.

To make your SOHC engine show HP, you will have to find a high cam, buy a cold air intake, a 4G63 throttle body, a header, a performance exhaust system, and for all these upgrades to yield a result, you have to configure the ECU. Do not waste your time on this. To install a 4G92 MIVEC head, you will need not only a head with a gasket and bolts, you will also need an intake system, an ignition system, a timing belt and everything associated with it, a fuel rail, a water pump, a 4G93 oil pump, a 4G93 oil pan, a front crankshaft seal, a MAP sensor, an IAT-sensor, and a good exhaust system.

You can start with the simple stage 1: a cold air intake system, a header, a performance exhaust system, and ECU tuning. Now in earnest. You can use a 70mm throttle body if you want. The exhaust system will consist of a header and a 2. But this is only the beginning, this will not be enough.

These upgrades will improve reliability at high rpm, and increase the compression ratio to You should port and polish the head, buy Jun type 2 cams, adjustable cam gears, a lightened flywheel, and an Evo fuel pump.

All this will be controlled by a Haltech E6X, or something else that you like more. All this will give a lot of power with the use of sports fuel. Yes, it is possible, but you will need a 4G93 cylinder block. It will be something like a stroker kit, but even better. After you reach the maximum power for 1. Leave your upgraded head and replace your small cylinder block to the 4G You should also add large cc 4G93T fuel injectors, this will be enough. In the end, you will get HP at the crankshaft, or even a little more.

If this is not enough, you can bore out your 4G93 cylinder block to 83 mm; this is the maximum size. It will give you 1. You can leave stock internals, but the pistons still should be replaced to make the compression ratio about These stock rods can withstand over HP.

We need to make an oil feed and an oil drain line for the turbocharger. Of the performance parts, you will need a turbo manifold, an Evo oil cooler, an Evo intercooler, an intake piping, a 4G63T throttle body, an Evo fuel pump, a fuel rail, an adjustable fuel pressure regulator, cc or more fuel injectors.

The exhaust system should have a diameter of approximately 2. As we say, during high speeds, the MIVEC starts to kick in and are switched into larger cam profiles. It has larger fuel injectors with cc and a 60 mm throttle body size. So let us proceed. So basically, this is a 4G93 in a 4G92 engine block with some minor differences. To add more power with that, you will need a cold air intake system, header, ECU tuning, and of course, a performance exhaust system.

Throttle bodies should be replaced with 70 mm, buy H-Beam rods, replace a lighter flywheel, ARP rod bolts, 81 mm high compression pistons, and ACL rod bearings. Next is like the stroker kit for the 4G On this one, we need to use the 4G93 engine block and bore it out to 83 mm to increase the displacement. You also need to install cc 4G93T fuel injectors, and that will give HP at the crankshaft and 1.

That increase in displacement is what we need to install the Evo TD05 turbocharger. After that, we need to replace the pistons that can make a 9. We need to add in some performance parts like the turbo manifold, Evo oil cooler, Evo intercooler, intake piping, 4G93T throttle body, Evo, fuel pump, fuel rail, adjustable fuel pressure regulator, cc fuel injectors, and a 2.

Install 4G93T pistons and connecting rods and oil squirters as well. These upgrades can give you HP. Engines are gone for good if we do not take care of it, the majority of all things, especially those with moving parts inside. Keeping an eye on minor problems can help prolong the service life of our engines. Some issues might arise on 4G92 engines, but take this with a grain of salt, for this is not an official list but more of a precautionary heads-up.

The first is excessive oil consumption. This issue is highly detrimental to the engine as the oil plays a massive part in keeping the engine at the peak condition as possible. If you have less oil inside than what is recommended, most likely, the engine will prematurely break down and overheat or, worse, fail. This issue is prevalent among old and deeply experienced engines, those who logged huge numbers into their odos. We said that because old engines have some loose components like piston rings, and most of the time are left in the corner to collect dust due to infrequent use.

You might need an overhaul for this kind of issue. The second is the Engine knock. The cause of this sound might come from the hydraulic tappets, and usually in these components. You need to check if that is the problem. If yes, replace them. The third is the rough idling or idle problem.
