Review of Toyota BB, Toyota Vitz, Toyota Ist

TRD turbo
In this small review, we will talk about what Toyota in the field of car tuning is new to us. There will be a little technical details the review, rather, is designed to simply draw your attention to the fact that Toyota not only produces ordinary cars, but also serially tuning them on their own, exposing TRD under the brand. In the world of motorsport, this is a fairly famous name. TRD Toyota Racing Development Unit Toyota, which is engaged in tuning refinement of serial cars.
Today, TRD has prepared turbocharged options for three small serial cars Vitz, IST and BB. Models Vitz Turbo, Ist Turbo and BB Turbo are designed and put on sale called completed TRD cars with full finishing. In accordance with the wording, complete refinement, their feature is that the changes affected not only the engine, but also the chassis, in accordance with the increased power.
At the same time, the TRD turbine refinement plan is prepared a menu for installing turbine engines on Vitz, IST and BB, which are currently driving. On the Vitz Turbo model, put on sale a little earlier, there was only a 1.5-liter engine and a 5-speed hand transmission, and now, in completed cars and according to the plan of turbine refinement on a 1.5-liter engine, you can also install an automatic transmission.
In addition (and this is very significant), the sale of new cars of this type and subsequent refinement is made by dealers. Naturally, any dealer cannot do this. Their number is limited by those whose technical level determined the TRD and who has undergone technical training on this refinement. Currently, these are 7 companies Master Van under Kanagawa Toyota, Hinodeten under Netza Toyota Sendai, Dzisupays with Natsa Toyota Gumma, Habarandoten with Natz Toyota Hoo, NVC Kurasiki with Netza Toutre Okayama, TRD Direct Schop Tamma and Tota Tekunokuranto Sibaura (two last two Do not sell new cars).
In addition to this, it is also possible to purchase and order for refinement through system dealers. Naturally, if the car was bought in Tokyo, then dealers in Sandai, Sokayama and other places can carry out its maintenance and repair.
There were many who did not dare to buy completed and brought cars, believing that it was difficult to buy and the service causes anxiety. But thanks to the deployment of sales along with dealers, the driven cars have become much more accessible.
 
Forting
So, what refinement did Vitz, Ist and BB get? Let's try to familiarize you with its content.
The turbine engine, which has become the main point, is a special product. It is made by IHI and is designed to increase volume (1,500 cubic meters) and increase the reaction. The boost pressure is 0.65, which made it possible to increase the rated power with 109 hp. up to 150 hp, and the nominal torque from 14.4 kg-m to 20.0 kg-m.
Since turbines were not previously installed on these cars, the rest of the parts is also necessary to install them. In particular, this is an exhaust collector, an injector (fuel nozzle) of a large volume, large fuel pump, spark plugs, an intermediate cooler and a set of pipes for it, a specially -minded computer (in total, 6 types are prepared, separately for each modification with automatic and manual transmission ). In addition, a large radiator and oil cooler is also included in the turbine kit, which is made in response to an increase in the heat transfer of the engine in connection with the installation of the turbine. Thus, the power not only increases, but all measures are taken so that the load is no longer necessary on the engine.
As for the completed cars, in addition to installing the entire set of engine refinement parts, the transmission kit and brake pads are replaced by TRD production parts, and complete refinement is carried out in accordance with increased power.
According to the refinement plan, the difference between each individual car is the greatest problem. Some cars work fine, while others are already tired. And in connection with this, a check is carried out according to the established parameters. If there is a need, then with the consent of the owner, the details are replaced and other work, trying to ensure that no problem arises after refinement.
 
Impression
So, real cars. There were only completed cars on the current run -in. When the owners receive them, they are worried about two points: will it not be difficult to ride? And did they really become faster?. The turbine refinement, of course, is attractive, but it will be unpleasant if it becomes difficult to ride. I think this is the right opinion. According to another opinion, if you do not like the fact that with turbine refinement, on the contrary, only torque increases at low and medium -speeds, it is better to give the car to the city workshop on refinement.
I also started running in, having both of these doubts, at first glance contradicting each other. However, if you start with conclusions, it was very easy to ride, and besides, at a pleasant speed. The use of a small turbine improves the reaction of the accelerator, and at the same time, the turbine is configured so that it begins to act with small revolutions. Of the cars presented this time, only Vitz had a 5-speed hand transmission, and on it I most of all felt healthy physiological sensations and rudeness (nevertheless, good obedience is noted), and it feels that the power growth process from 3000 to 6000 revolutions has been worked out Very carefully. On the contrary, the automatic transmission is very smooth. From about 1,500 speed you already feel the pressure of the turbine, and acceleration begins with an easy sensation, as if the weight of the machine has decreased by two -thirds. I thought that at high speeds the pressure would reach the peak, but the growth within these limits is also normal.
In any case, there is no explosive sensation of power, and it seems that the torque is smoothly increasing.
In general, these machines are very pleasant in action, and do not cause rejection. Each dealer has a run -in cars, so I recommend that you first try them out, and thus you can always choose the one that will like it more.
