The two Evos are like a pair of brothers, so of course there's a difference between the big brother and the little brother. Both units have Jun's front aero kit, Voltex's rear aero kit and are yellow in color, but how do you separate a lighter Evo from a darker one? Well, if you're looking at the extent and depth of the modifications, then the darker Evo?VII is the one to beat. Why? Open the hood and you'll know. After opening the hood, the first thing you can see is the HKSGT3037s turbo, which is stronger and bigger than the stock turbo, the Wastegate, the equal-length exhaust banana and the SSQV. Some might say that these parts seem a bit lineal for an Evo, is that all it takes to make it a big brother? Besides, although it is said to have the GT?3037 kit, without the other parts, how much performance does it have in it? As a matter of fact, the engine bay of this Evo?VIII has a lot of parts hidden inside the engine other than those we can easily see, and these parts can be considered as the important parts that make this car fast. So what are the other parts? Let me tell you all about it.

After looking at the exterior, let's get right into the drama jade. The author said earlier that this Evo?VIII has a replacement turbo kit, which means it will be more explosive. But with that said the question arises, although the stock connecting rod pistons can still barely withstand the enhanced explosive power, can its durability really be as good as the stock power? In addition, since the turbo is driven by exhaust gas, so to speak, if the turbo is enlarged, and the engine's exhaust volume remains the same, then the turbo Bar will be slightly weaker than the original, although the car is said to have adopted the HKS?3037s, a ball-bearing turbo, but after all, in order to make the turbo Bar still need to rely on exhaust gas, and if the amount of exhaust gas remains the same, then it will still be lagging. So, the owner has beefed up the engine's internals. The fastest way to increase the exhaust gas volume is to increase the exhaust gas volume, and the owner's solution to increase the displacement for this 4G63T is to add the HKS 2.3?Kit, and in order to make it more durable, he added the forged connecting rods and crankshaft kit. In addition, the camshafts were replaced with 272-degree camshafts for greater valve opening. All in all, the engine has been strengthened.

Besides the body of the engine, there are of course other things that need to be done to bring out the full level of power, for example, the turbo is bigger and compresses more air, so the original intercooler will probably not flow enough, and the hot air will affect the engine's output, so the owner replaced the intercooler with one from HKS, which is a bigger intercooler that corresponds to the turbo. Mechanically, this big brother's enhancement can be considered perfect, but can it move? Oh no, this can not move it, there are hard still need to be soft to be able to do, and still have to transfer power to the gearbox ah. In the software part, to brush the computer? No. Japanese cars, especially the more traditional models like the EVO?VIII, have the option of utilizing an external computer for tuning. This EVO?VIII is tuned with HKS?F-Con?V-pro. As for the transmission, the EVO's gearbox can handle the sudden surge of horsepower, but the clutch needs to be upgraded, and the owner chose an ORC dual-plate clutch to transfer the power, so that the engine's torque can be fully and directly transferred to the transmission.

Well, after the big brother let's talk about the slightly weaker little brother. Although this is the little brother, but it is not just the original so simple, Evo such a good modification of the base how can not change the reason? This Evo?VII is not as y modified as its big brother in terms of power, but the power has still been strengthened. This Evo?VII has a TD05-20G turbo with more horsepower, which is the same size as the 3037, so the corresponding horsepower is also the same. However, although the turbo was enlarged, the owner of this Evo?VII did not have the engine expanded, so, theoretically, the response of the turbo should not be as fast as that of its big brother. In addition to the turbo, the owner has also enhanced the computer and turbo control, using an ECU from Ralliart instead of the original, and utilizing HKS's EVC to increase the turbo boost to complete the power increase. No further changes were made to the Evo's power, not because they couldn't be made, but because the owner believes that the Evo's main purpose is not to go to the track, but just to get out and have a little fun, so the horsepower of the car isn't a major concern, but rather a small enhancement that won't be too hard on the driver.
Figure: Why is the Evo VII, VIII and IX engines? It's because the Evo IX incorporates MIVEC, while the VIII is different from the VII's 4G63 engine in the valve trim cover.

Here the power is even finished, so next to the conclusion? Not so fast, the power is there, the transmission is there, of course, can not be without handling and walking ah. If the two Evo's current power performance is not strengthened for the handling and walking brake, it will make the vehicle seriously unbalanced, not only can not play out the original performance level, but also make the vehicle become very dangerous. Remember, it is not the power or the handling that makes a car fast, it is the overall balance, and the higher the balance of the vehicle, the faster it will be. Okay, enough of the nonsense, back to the cars. Both Evo's have been enhanced in handling, running and braking in addition to the power enhancements. For the big brother Evo?VIII, the owner only added a set of HKS?Hipermax?III shock absorbers to improve the handling performance, while for the running, the owner chose Advan RGII wheels with a set of Yokohama?Neova?AD08 tires to improve the vehicle's grip, and for braking, the owner chose a set of AP?RC.RC.R wheels with a set of Yokohama?Neova?AD08 tires to improve the vehicle's grip, while the owner chose a set of AP?RC.R.R.R.R.R.R.R.R. wheels to enhance the vehicle's handling performance. As for braking, the owner chose a set of AP?Racing front six and rear four brake kit to cope with the enhanced engine power. As for the little brother Evo VII, although a set of Advan RS wheels has been replaced, the tires have not been changed and the original Dunlop Sport 600 tires are still used. For shocks, the Evo?VII owner chose a set of Ohlins Road&Track shocks, while the brakes remain stock.

Photo: The owner of this Evo?VIII chose a set of HKS?Hipermax?III shock absorbers to enhance the support, but I think this Evo still has more room for improvement in terms of handling.
Combining the handling, running and braking modifications of these two cars, I personally think so. First of all, the Evo?VIII has been expanded, the car has undergone a very deep transformation in terms of power, and the power is quite strong, but in terms of handling, it is only strengthened by adding shock absorbers. In fact, this is not enough to strengthen the handling, although the HKS Hipermax III shock absorbers have already brought strong support, but the car needs to withstand large lateral inertia force when attacking corners, the frame's ability to withstand will always be put to the test. Although it is said that the original imported Evo in the frame rigidity relative to the domestic production of the model is much better, but how to say is also after upgrading the model, the frame will still appear overloaded situation, so adding for the frame to strengthen is still necessary. In addition, if a set of stiffer sway bars could be added to the car, the handling response and traction in the corners would also be improved. As for the Evo, which has not been expanded, although the displacement has not been increased, the turbo has been replaced to increase the power, but can the original tires withstand the increase in horsepower? I think it should be barely, although the owner is only used to represent, but the tires can not only make the vehicle steering limit increase, but also make the braking distance shorten ah, which is also a kind of guarantee for the safety of the vehicle, so I think, this Evo?VII will be slightly improved tires, then the balance will be even better.

Photo: In terms of braking, the Evo?VII's braking system remains stock.
Photo: The shock of choice is Ohlins' Road&Track series, which not only has stronger support, but also boasts Ohlins' original DFV technology, making it a pretty good set of shocks.
Many people think that making a car fast means making it have a lot of horsepower, is it really that simple? Of course not, as the author said in the previous article, to determine a car fast and slow is its balance, rather than a separate aspect of strengthening, as long as the balance is high, the vehicle will really mean fast. Of course, this fast and slow, not how fast it can run on the street, but talking about the lap time on the track. Or some people may say, my car is not even for running tracks, why do I need such a high balance? Well, let's put it another way, it's the balance of a car that determines whether it's good to drive or not, so let's be clear about that. Yes, balance for the track can determine the speed of the car, while for ordinary cars, balance represents the car is good to drive or not. In the past, I've seen a lot of media say that so-and-so's vehicle is 0 to 100, and how much horsepower it has, in order to illustrate how fast the vehicle is. Is this an adequate description? Some cars, although its power is very strong, but the handling performance is a mess, the balance is so poor vehicle really fast? Fast ...... but only in terms of straight-line acceleration.
