Hi Steve, you have made a reasonable start already, when you say Beef up, what are you wanting? What is your goal?
We all have to have an idea of what we want, what do we envisage when our marriage is on the rocks, the kids don't recognise you unless you are covered in oil and wearing overalls and you're on the verge of financial ruin? Once we have that vision we have something to work towards.
It might be a simple thing like a sweet running stage one which has ironed out all of the manufacturers bottle necks, or it might be a street legal race car. Either way you need a plan, a road map to work with.
I encourage everyone to make a folder up with ideas, plans, pictures and drawings, whatever is required to create your vision. You need lists with parts, research and prices. All of this helps you to consolidate the vision.
Once you have this you have something to work towards, a realistic idea of what's achievable within your budget.
There is no point in wallowing around aimlessly..... Here's where to start..... Let's chat....
