good luck
be sure to check out www.k20a.org .. all the K help u will ever need will be in there.
Your gonna have to get fuel lines/fuel rail/fuel pressure regulator.. custom headers and exhaust among a few other bits n pieces more than likely.. u also should upgrade suspension inc. sway bars etc and brakes.

So id put that $300 to something else, and add a turbo at a later date.. thats just my opinion though

Did u end up getting a K20A (JDM Type R) or K20A2 (USDM Type S)?

the JDM K20A comes with 220hp
