My Is250 Is Faster Than Usual?

[fast lane]

Hi,

I have an IS250 US import. The thing is, it feels very quick. 0-100 in about 6 seconds with to

people or more in it. Also when testing this, a big pull comes after like 50km/h. Like some turbo

kicks in. Really strange. It does 0-200 meters in about 8 seconds.

See a few clips here:

Now, could any experienced engineer here explain to me why this is? I've read that there are almost non

turbos supercharges on the market for IS250. And if such very expensive what i've heard.

I'm not good at engines at all so it's no way I could tell, after talking on other forums and comparing

engines we're sure its an 250 engine, but could the turbo been hidden away somewere?

Also, the VIN number, how hard is it to find on the engine?

Thank you!
