New to Mazda 3 forum

I have a 2009 Mazda3 2.3L Hatchback with 180,000. I have done quite a bit of work on it and want to keep it running as long as possible. My son is driving it now and I want to keep it in good working order. I am currently looking at replacing the rear coil springs. I am wondering what brand of coil springs I should use. I am thinking about using genuine Mazda parts, or Precision coils. Any recommendations?

Is there something wrong with your current springs? If not, there really shouldn't be any need or benefit from changing them.

One thing I would budget for is a new engine. the 2.3 liter engine is well known for sudden failures, especially beyond 100,000 miles (and yours is well beyond). Regarding an engine replacement; search this forum, there are numerous threads on converting the 2.3 to the highly regarded Ford Duratec 2.5 (basically the same engine externally, but with significant internal upgrades which yield superior longevity, better power, and virtually identical fuel economy).

I don’t post here much anymore, but I’d like to know where this “sudden failure” information came from. I know several people (myself included) that autocross/track their 2.3 3s well over 150k and some over 200k with no issues. I don’t mean to say you’re lying or anything, just curious.

The automatic transmissions are known to be problematic over 150k though.

Do a few searches here, you'll find many dozens of examples. That and take a look at the number of long running Mazda 2.3 to Ford 2.5 liter threads here for more examples.

The fact is, some 2.3 liter engines to Tango Uniform well before 100,000 miles and maybe half are dead before 200,000 miles. Not exactly a stellar reliability record.

Whether that’s true or not, that was a great way to welcome the guy to the forum. “Welcome! Don’t replace your springs, replace your engine!” Lol

Hey, I'm just the messenger here. Given the high percentage of 2.3s which have failed, if someone is forewarned of the possibility, then they can be forearmed to deal with the issue if/when it happens.

Personally I really liked my former 2009 Mazda3 and have been keeping an eye peeled for a nice 2009 Mazda3 s GT (5-Speed Manual) in the 4-door body style with a blown 2.3 engine. If/when the right opportunity pops up, I'll buy that sucker and do a nice Duratec 2.5 conversion on it.

Hey Z, we have a new member who signed up today which, on the surface at least, sounds like another 2.3 liter failure story; here's the thread:
