Well, I'm looking at cheap ebay turbo setups. Full universal kits for under 1k. I'm hopefully selling some stuff and saving up enough cash to buy one of these kits. Their not the highest quality, but it will work for now. My Valiant is at 70k original miles. I just plan on rebuilding the factory drums for now. When I do get my license, this will not be my daily driver. There's actually no leaks surprisingly. The car had been sitting in a garage for nearly 30 years. When I do the whole turbo build, I plan on keeping the motor stock. I just want to open it up, check over it, and replace all of the gaskets. Paint it, and drop it right back in. Swap the carb for a 2 barrel, and just throw a ebay turbo set up on it. Just run low boost until I can afford to rebuild the motor incase it blows. I was just thinking about changing all of the brake lines (just to be safe) and rebuilding the factory drums for now. Until I can afford a disk brake conversion. This is pretty off topic but I found the original build sheet to the Valiant!!!
Not trying to be negative, or change your plans.
But a 2 barrel swap usually involves a Carder BBD carb, they will not work in a blow thru turbo application.
You will most likely end up with a modified Holley carb $600 and a different intake $400 so add another 1k that to the original 1K.
Also you will have to add a boost referenced fuel system, low end units will run you about $500.
At a young age I do not want to see you spend your money on something that will become a mechanical pain.
You need to spend the money and make the car safe and reliable where you can drive it.
