you will need it add a few wires to your Harness

you will also need a set of the Series 2 fuel rails, injectors TB adapter and a L67 or more favorbably a N* throttlebody.

you can MAYBE run a 3.6 pulley with a decent tune

I would suggest no small then that pulley. You will need to scan for KR. If you want to go smaller you will need to look at 1.9:1 rockers or better yet, a cam.
