Thank you all for your responses.

I have a LS..and i dont want to do a swap cause i dont have the money and its my daily driver.

Im thinking of getting a turbo kit off ebay and have turbo dave build piping and get a nice manifold. The reason i said 6psi is because i dont know how much is a safe amount on a car with that many miles.

99SI- I dont beleive i have ever heard your car or seen it. I dont even think i have met you? lol

I could rebuild my engine, did it in school, but i dont have the time or equipment.
