Nissan 300ZX Twin Turbo Part 3 2010 HD

- After this little retrospect let’s talk about the Nissan 300ZX of Roland Szentpáli from 2010. What kind of changes were made in the last two years?
- Well, the car got 1-2 extra things but of course before this it was also full of components which weren’t original but it benefited the car absolutely. When it got a big intercooler in its hood, it had a very good design in the front and it refrigerated the air well but we couldn’t solve the factor to insure good refrigeration for the car. And the motor was heated mostly in the summer commonly. Then there was an idea that you could by intercoolers for the sides the way how it was produced. And I bought these bigger intercoolers for the sides so the air filters had enough place to let beckon them. The oil refrigerant and the water refrigerant fit the place behind me quite comfortably because before this there was the intercooler, then the air filter was at right angles to the ground, behind it there was the oil refrigerant and behind it there was the water refrigerant and behind it the motor was found. So the motor hadn’t almost any refrigeration but now that the intercooler is on the sides, only the oil refrigerant and the water refrigerant is before the motor this way the oil is cooled very well, so is the water and the motor is, too.
- And there was a very important change, you have changed the fuel.
- Yes, this car uses hundred percent of bioethanol (E85) that is very comfortable because the car drags better during the lower turn. Well a car with 3300ccm V6 turbo hadn’t any problem until now but we can realise some changes. It uses more fuel of the ethanol of course but it is still cheaper than to fuel up the car with the benzine type 100 and to solve this situation to use the fuel type E85 for travelling that is why I bought a computer which is produced by the AEM and which can be written so we can say that there is two programs on the computer. There is a 1 bar with turbo pressing program for benzine type and a there is a 1,5 bar program for ethanol which we could change with some clicks if we connect a laptop with the computer.
- How was this programming made? What do you need for this?
- Well, first of all we need the computer what we had to change. Otherwise this is the new AEM computer and this is plug_and_play which means that if we connected it to the origin cables normally than it would work also with the sensors which were made in the factory. So this is a very positive thing. But we would like to make the programming on the car as good as possible in this case that we have the possibility to put such a professional computer in the car like this. So the car got two broadband lambda probes instead of the origin lambda probes. Now the air gross gage is out of the car and there is a machine to take the temperature of the air which was imbibed by the car and it is in front of the butterfly valve. This way the computer submits the amount of the fuel in connection with the actually temperature of the air. So the burning is always much preciser and the whole car is much effective. The motor can work with much bigger performance and the amount of the fuel is always optimal so it never enriches itself too much and the fuel is never poor of mix that is very important. This way the performance of the car is bigger and I can say it decidedly that the car uses less fuel.
- And how works this process to make the programming? How do we have to imagine it?
- Normally the way that we bring the car to a place where there is a bank. We stand up the bank, the gentleman who can make the programming take a seat next to us and he connects his laptop to the car’s computer and we install the origin software of the AEM. Then he regulates the graphs and pays attention how much air how much benzine needs and how much fore lighting the car needs, etc... Because we didn’t manage to find this kind of bank we went to the road M0 motorway.
- Let’s say that you went to Germany. /Because there is no speed limit on motorways/ :)
- Yes. We can say it. So we went to Germany and we spent some hours there and we used some litres of fuel to regulate this. But the programming was already made on this car by this computer first for fuel type 100 and this way it didn’t take so much time. So the first time to make the programming on this computer took 5-6 hours, the other programming with ethanol took only 1,5-2 hours. So it was more faster because there was a kind of graph which only had to be transcribed with the ethanol one.
- And how is it with the consumption? Wait. Let’s begin with the question how was it?
- Yes, so I say it in connection with benzine. When it had the program for benzine 100 on 1 bar then when I didn’t let it kick so when I went by this car on the road with the speed between 110-150km/h or when I went to Debrecen then my car used 12-13 litre benzine type 100. Now it uses 16-18 litre of ethanol. So it uses as much from ethanol as 9-10 benzine type 100. And when I come to the airport and when I go for a drive here then it used 16-18 litre of benzine type 100 on 1 bar and now it uses 20-22 litre of ethanol on 1,5 bar which means the same like the amount of 12-13 litre of benzine type 100. Honestly I am very satisfied with this and as long as there wasn’t this computer in this car but there was a computer with a chip which was ordered from the DTA motorsport. The DTA is a professional firm. So it is not somebody here whit a bit brain who found out that he makes the programming on the computer. This car used a lot of fuel: 23-25-28 litre. So this way the car works with much less fuel. And so that the car uses ethanol and if we would like to say it in benzine 100 because this car is not able to use benzine type 95 anymore, the car works with less fuel. And I think that we don’t have to expect from the car to use 5-6 litre namely it uses this amount but we have to put a number 1 before the 5-6. Because if a car has performance than it needs fuel. A lot of air has to be burnt with a lot of fuel and that causes the performance.
- And how big is the performance?
- Well, we don’t know this. We haven’t managed to calibrate it yet. The car mechanic said that it must have 500 horsepower. The guy who made the programming sat in some kind of cars like a car with 8 litres, twin turbo, nitro, Dodge Viper etc. and also he said it that it is sure that the car has more than 500 horsepower. The contractors say that “Receipt praises the day”. But I don’t know. We should calibrate it. But I don’t know. What’s the odds how horsepower it has? Because the experience of the driving won’t be better if I know that it is 507 or 500 or 492 etc.
- What kind of travel dynamics it has? What can we feel from it?
- The first speed is useless because if we trample the clutch it is only good for burning the tyre. The speed has the programming that it works from the rev 3000. And the weather is getting colder so the third speed can we switch by more speed because the cubage of the air is less and it can be compressed by more speed. On the other hand the tyres adhere less but I came to know that we can use the third speed quite good in the summer. And maybe there is a connection between the facts that the car got a one-piece aluminium Carlen has nothing to do with the road-holding but the fact that it got a TEIN rear shock-absorver doily from Japan which is more harder than the KYB which was under it. And I feel that the car is less unruly so it is true that it is not enough to invigorate the car’s motor but a very good set-up must be made on every car. And then we can get its maximum because if there isn’t any power on the road than it effects nothing.
I think the maximum speed of the car is 300 km/h and the fifth speed is around 240 km/h. So there you have to switch the gearshift. But I am not so brave to drive so fast so I heard only legends about it.

- Now let’s see the speed-up. It is said that I have to forget the first speed but I use it only to start the car to avoid burning the car. 60km/h. 80km/h. 100km/h. 120-140-160 km/h. 200km/h. We can come up with 200km/h on less than 500 metre. Just let’s stop Oh my God. Well there are here a lot of horsepower. This is maybe the strongest car in our programme. It goes so fast. Let’s try it again because it’s impossible to be bored of it. It is like a catapult blastoff. Let’s try to hold the car on the asphalt. We start with pedal to the metal. 60-80-100-120 km/h. 140-160 km/h. My heart is sticks out. 180-200km/h. 220 km/h. It is horrible. Oh my God. It is impossible. I could come up with 220 km/h on less than 500 metre. It is impossible. It is horrible. This car goes so fast. I can’t say it with words it has to be felt.
