1.75TBi upgrade!

[acab]

We made good hybrid K03/K04 for my AR159 with 1.75TBi engine.

Billet aluminium compressor wheel. Very nice config !
We will try get 300+ with remap.

This is 1,75 with stock turbo;

with your upgrade should be more than 300PS ;-)

Giulietta QV? Nice. I also have similar peak around 4k RPM, I thought that is something unusual but now I am little bit calmer

[acab]

You sure? May be in Giulietta QV?
Stock turbo from 159 veeeery small for 300hp.
240-250hp possible...

Its magic?

What about M32 gearbox with +300 HP engine?

[oleksy00]

I am not sure but only first series had m32, rest was based on c635

Every 159 with TBi engine has m32 gearbox.

Isn't any magic....
This is Alfa Romeo Giulietta QV 235HP man. My2013
Stock: 235HP/340Nm
Measured: 250HP/340Nm
Mod: 290HP/450Nm

See the difference. 159 TBi is combined with M32 (torque >440 will kill that gearbox immediately) and smaller turbocharger. Maybe different injectors also?
@acab you need to swap gearbox first Depends on desired torque of course.
