How much longer till my engine blows?
 

I have 125K miles on my engine and it is an original engine. Im wondering how long you think it will take to blow? How many more miles can i expect to put on it? I have an Apex'i air intake and a Racing Beat catback exhaust. also everything else besdies the actual motor is new.

There isn't any way to tell, really.

do a compression check and thatll answer your question....

start saving up cash thats all I have to say

If I may be so bold: I really depends on how you drive it and the quality of the original build. Do you have the reliabilty mods? Boost gauge? The original engine on my car crapped out at 116k miles. Most engines are rebuilt ALOT sooner. But if I were you, I'd start saving up for a rebuild.

If the car idles smooth and runs good don't sweat it, I have seen engines go 145,000 plus miles. BUT the rubber seals are 13 years old and most likely weak. Oh, I have a Mazda compression tester.

You ever thought rebuilding the motor before it goes, because I'm planing to do some mods to my fd, and just to be on the safe side I wanted to secure the motor before I do some major mods

thats the right state of mind buddy;)

Yeah, really no telling for sure. As said before I would say get a compression test done, or if it idels smoth and/or is not leaking a ton of oil you should be ok for now.

It wouldn't hurt to rebuild it now if you've got the loot. You may save some money on new internals that way.

I am shocked that you are still on the first engine with that many miles. Are you sure that it wasn't replaced by Mazda under warranty earlier in it's life? Most FD engines only last 80-90K miles before a coolant seal goes. Are you on the same set of original turbos also?

Jesus, DDagman! I hope to hell you are knocking wood when you say things like that! :eek:

I have to agree with others here, in saying it could be unlikely that this is the original engine. While not impossible, it would surely rank it right up there with the most-long-lived 13BREW if it IS orginal miles.
But you just bought the car, right? I am assuming you could be the third, fourth or more owner? For all you know (or have told us thus far) the engine could only have a few thousand miles on it, and you can look forward to years and years of trouble-free service.
I certainly wouldn't assume that the engine is going to expire at any moment! If it runs good, has no coolant system problems (the #1 killer.... or at least tied with apex/corner seal detonation damage....of engines) or any other obvious sign of trouble, then just enjoy it and don't go looking for trouble...lol! The Rotary Gods have a way of smiting thee.......

even with a compression test you really dont know how much longer it will go. I had great compression at 112k but the water seal went shortly after the test

one of my favorite member quotes from a similar thread.

Im sure its the original engine, my dad bought the car in 2000 as his and then passed it on to me. Im positive its the original engine, but the turbos are new J-spec turbos and my mechanic found and sealed a bunch of leaks.

my new fd i got if off an older guy the car was all stock and he was the original owner. The cars engine got strong compression at 134k i dont think the guy even knew what boost was one of the intercooler pipe was off when i drove it for the first time.

mine went at 138,000 but i dont know if it was ever rebuilt. o rings went bad.

If you change oil every 500 miles and drive like a old woman you may never need to rebuild.

i have a better question:


how many licks does it take to get the center of a tootsie pop?

WRONG.

For the love of god, will you STOP posting idiotic replies to questions you have no idea on? Everytime I see your posts, they're either worthless questions or your responses (like this) that are never based on fact, and serve the purpose of leading fellow FD owners astray.

To the original thread starter, DO NOT believe this statement... I would believe it's actually the opposite. I'm sure sonix and rynberg and dgeeseman will respond soon with a more fact-based response...

edit: actually rynberg already responded above ^^

if you change your tranny fluid every 50 miles, you can bang gears 50 times a day for 100k miles and the gears will never grind.

Hihi :stick:

Your engine will blow on january 27th at 4:21pm. With exactly 125,991 miles.

hes right you know
