Going to an Altima

Due to a recent run in with the law my license is suspended for a year, so I am selling my nissan 240sx to cover some court costs. Now that I will have a year to save up I am looking into buying a nissan altima. I read somewheres on the internet that they have a ka24de engine, I was just wondering if this was true. I was also wondering where the best place would be to just look at Altima performance parts, just so I can get a feel for what I am getting myself into. Thanks for all the help you can provide me.

it depends on what year. the new ones have qr25's but yes, the old ones had ka's.
