Hi all,

Aware of the whole naturally aspirated, supercharged, and supercharged plus inter-cooled. With the variants there are different power outputs.

TLDR is it straightforward to upgrade a 205hp to 255hp and what is the process?

I’m in the market ideally for a challenger 180 SP. however there are way more 180 SE on the market and most of which are 205hp (cheaper too). That may be enough and perhaps a project I don’t need. Still curious though if I could achieve my equivalent SP by adding perfect pass, wake tower and modding the engine to some extent.

I saw some posts like this none answered apologies if it has been answered.

Cheers.
