lay out a budget and some goals.

test drive a turbo LS before you commit to it. you say you cant afford to blow your motor, which typically means you should NOT turbo it.

even the most elaborate, well planned kits can and will break parts. just a warning.

when I first turbo'd my old LS, I had a daily driver. I boosted low and it was even tuned on Crome. My motor didnt let go, but I constantly had to monitor many of the supporting mods such as the cooling system, the oil lines, and other small details that tend to get overlooked (rubber/plastic hoses failing due to the added heat under the hood, etc)
