You might want to find yourself a parts car so you can just swap out everything.
craigslist classifieds: jobs, housing, personals, for sale, services, community, events, forums is where I found my SVO for less than $2,000, but now I do not want to use it as a parts car. I might just buy the parts seperately for the 2.3. It can run you for about a couple thousand I'd say. That includes 2.3T engine, suspension, exhaust, computer, injectors, intercooler, etc. Doing some research to gather information on the 2.3T parts. There is a thread on the "Talk" area which also tells you the differences and can give you an idea of what is needed.
