Stage 4 and Stage 5 turbos? confused!

You can add the '99 Skylines to the list of cars where the stage 5 turbo's are more powerful than the stage 4's. (GTR, GTR V-spec. I'm not sure about the N1 though.)

I'll admit. When I first started playing I was building the snot out of every car that I bought. All of them were high powered, and all of them dominated every race that I entered. It got borring pretty fast. I ended up spending more time looking for cars in the used car lot than racing. At the 3rd appearance of the black cars, I was only at 60%.

So I ended up starting over, and decided to only build the cars when I needed to, not when I wanted to. Its a lot more fun trying to out drive the competition than to out run them.

Will I go out and build a beast of a car again. I probably will. But only when the competition is beating me on a regular basis.
 
It's about power under the curve. Stage 5 usually give better mid range through top end, only falls behind the stage 4 near the red line. So you can accellerate much faster throughout the rev range with stage 5 than stage 4.
 
I've never read so many strange, false and irrelevant answers to a (serious) question on GTP, ever! I don't mean all answers, but there were a lot! :dunce:

The describing texts about turbo stage 4 and 5 pretty much say it all:

- stage 4: ignores lag and low rev power, but maximizes power in the upper rev band
- stage 5: gives a very good overall power, with good low rev driveablility and good high rev power

The stage 5 is a turbo kit specially designed for the specific car. So, it is a little bit cheaper than a custom made kit. If you'd bring your car to a tuner and ask for a high power turbo kit in real life, you'd also pay more if he had to custom build it for you. If there'd be one that has already been developed for your car, you'd pay less.
On the other hand, it doesn't give you the maximum power, just like the text says. It's the best high power overall package for most of the cars. So, if you tune a car for max speed, take stage 4, if you tune a car for power and driveability, use stage 5 (if available).

Also, on a R34 GT-R N1 (the CF bonnet one), the S4 turbo only offers 1 hp more than the S5, but costs about 9k(?) more.

You do the math. :)
 
Biased turkey
imho
I played the GT serie from the beginning and only use stage > 3 on banked oval racing.
When people talk about stage 4 or 5 for a rally car, I'm laughing my a$$ off :)

Personally a was doing dirt and snow in Special Condition Hall in a Subaru Impreza Rally Car Prototype '01 and i wasn´t able to win some of the races in Hard level, specially against Delta S4, then i put a stage 4 turbo and it became quite easy.

Besides that I only use Stage 4 in group C cars and in Suzuki Escudo (never raced on him).
Never used on a stock, touring or LM Edition car
 
I know I'm about 3 pages too late on explaining this, but I thought I would add my quick interpretation of the StageV turbo.

First off, doesn't the game explain that it's a step past the Stage IV turbo, but that it has the same overall boost as the Stage IV, with more low end horsepower? And I haven't checked in a while, but I believe it's also OEM equipment that's been modified, and would thus still only be a Stage I turbo with high boost, which would explain why it's got all that low end power.

But that's just my interpretation of the equipment designation. That it's not a bigger aftermarket turbo making all that power (because bigger turbos require more time to spool up), but a modified smaller turbo. In that regard, it would be quite superior to a larger turbo in eveyr way except CFM numbers.

But the point of my rant was to explain why you would still pay more for a turbo that seemingly does less (Stage IV). When I build a racing two-stroke motor for someone, be it Kart, Jetskiing, or dirtbiking, one of the main considerations with that motor is how peaky they want the powerband and how high up they want it. ALL motors build power in an escalating fashion, that is, power increases with RPM's, until volumetric efficiency collapses and power drops off - this is represented as the "peak".

Why would you want a peakier motor over a smoother motor? Often times with a professional racer, they are better at using the motor in high RPM's than a novice racer, as well as being able to better use the steeper powerband that accompanies peaky engines. As well, those said motors tend to make more peak horsepower, though not more average horsepower. Motors that have a lot of low end horsepower and less high end horsepower feel "squashy" to a racer; meaning when they mash the gas, it doesn't seem to get faster, even though their motor makes more average horsepower and is much more controllable than the peaky pro motor. The reason lies in the difference in power output between a given set of RPM's - on a violent, peaky motor the difference is great, while the smoother motor is less.

Make sense?

In short, the peakier motor makes more horsepower; as well, a pro can actually use that power "surge" to his advantage, rather than the feeling of sluggishness. However, a smoother motor will be more controlled for a beginner or tight track, and be less tiring.

I know these are real-world analogies and comparisons, but GT4 is so realistic that it would be a sin to believe that these principles don't apply to the game.
 
A bit off topic, maybe. But I must say, I dislike the fact, that the tuners offer the same parts (the original are tuner-only, though), at the same prices, with the same power, as the car makers (AMG, RalliArt, TRD, etc.). Why can't HKS be pricier, but at better quality than Blitz, for example..
Oh, by the way, I use a lot of Stage IV turbos, I don't mind lag. But, the Stage V Turbo is incredible! 👍
