This is the site I have dedicated to my ever growing project which has quite simply been dubbed LA1 Z24. I'm 23 years old from Long Island NY. The car is a 1991 Chevrolet Cavalier Z24. It started out as a 3.1L, 3 speed automatic. It's now powered by a 2002 Grand Am GT 3400 (LA1) mated to an Isuzu MK7 5 speed transmission.
