wow so many cranky people on here

But most of what is said is true

A topswap is the better choice dollar for dollar and depending on your mechanical ability its easier

find a s/cd engine complete and take all the top end and swap over or just swap in the complete engine
get a tune and your in biz

cam builds are a little more in depth and the cost can rise pretty fast

Plus once you start modding it gets addictive and then things will start breaking
