2018 Cruze 1.4 turbo cyl head.

1104 1
I was looking at the 1.4T engine and noticed the exhaust port is a single or dual port to the turbo?

The turbocharger bolts directly to the cylinder head?

Does anyone have any flow numbers on these cyl heads?

Seems it would be pretty restrictive as compared to a four port exhaust head.

It seems it is made for economy and not so much for performance?

Does anyone have pics or links to a bare cyl head?

The older 1.4T engines have four ports correct? 140 HP & the newer 1.4 153 HP, is the boost higher, different cam timing?
How did the engine get 13 more HP?

Just curious.

Thanks

Larger turbo and direct injection over the gen 1 is how they get more performance. It never was nor will be a performance car, it's all about economy. With a tune though, the Gen 2 is much more capable than the gen 1, pushing nearly 200hp with ONLY a tune and no other parts.
