in a couple of months or so i plan to buy an 05 cavy and i want to put a turbo in it. i am really not familiar with turbos at all so i am getting someone professional to do the install. i know the hahn stage 2 kit comes with basically everything i need but what else is needed? should i go with 3 inch exhaust, how do i tune it, etc? like i know nothing about turbos and i just want to know more like what bolt ons can i have with a tubo...it just makes no sense to me???

It's all there. You can upgrade it with a 3in exhaust if you want to, I did, but you can easily run your stock exhaust. The gains won't be nearly as high but it can be done. The kit gives you basic directions on how to tune the kit too and it's pretty easy.



I used to race cars, now I race myself.

Might want to do some reading up before you install it

Money well spent
