Re: Turbo beginner questions
All of the above posts contain excellent advice.
If you are a race only application then ask yourself what you see more of at your local track, what you see the most support for there and just how much work you want to put in.
It is far easier to transition from nitrous to blower than turbo. Staging, driving and tuning is easier IMO.
If you can't find your welfare check, try looking under your work boots.
