First Mods

[riwiho]

Depending on the health of MY05 170hp Cooper S what is the sort of gain I can expect from getting the following mods:

1) 17% pulley
2) new plugs
3) GRS intercooler?

Thanks

I've had similar done to mine (minus the GRS, been a buggar to get hold of but I'm assured it's on it's way, I've not had the power values checked yet but I can assure you it will bring a big smile to your face and your next question will probably about your brakes.
As standard the brakes will not last too long but I have a great setup on mine that is quite a bit cheaper than a big brake conversion and can handle the increase in power. Have a look into Nitrac discs and EBC yellowstuff pads, with those mods you might need them.

Enjoy!

I actually did my breaks earlier this year and went with EBC pads and discs. Big improvement over the standard set up so hopefully this should manage the increase in power that will come from any future mods.

Gains depend on how healthy your engine is at the start, they can vary a lot in power.
