dont waste your money on a swap its not worh it $$ wise, get a gst/x or turbo the 420a. upgradeing the internals and turboing the 420a is an easier option for anyone b/c i dont have to wait for stupid papers and loans or whatnot, but the car will most definately have atleast 2 week down time and that to the etreme least if your lucky that no problems come up or that your the only costumer w/ a devoted mechanic.
