Twin Turbo or not?

Post by zedwheels » Tue Oct 30, 2018 4:49 pm

May sound like a silly question but I have my eye on a 2 ltr M Sport E89 zed and I know little about them, so, I know its the 4 cylinder turbo but is it the twin turbo or not??
I was chatting to someone and they said that its not the twin and I'm now doubting myself. :?

Sorry all I just found a utube track that confirmed it is a twin power turbo. Should have done some research first. :roll:

All the 4 cylinder models are 'twin scroll' turbo. Not quite the same as a twin turbo, more like a 2 in 1 turbo.

It’s known as a twin scroll turbo because of the way the exhaust manifold is plumbed to the turbo :thumbsup:

It confuses quite a lot of people, I've even watched reviews where the reviewer says that its a twin turbo. The fact some engine covers have twin power turbo on them doesn't help either.
