OH NO!!! engine blown!

[hello2000]

Yeah as you can see my engine blew last night. I was driving on I40 at about 70mph in 5th gear. I noticed a sound like something was draging the ground. All of a sudden, The engine blew and smoke came out the back. I pulled over on the shoulder and seen that oil was every where. There is a big whole in the side of my engine. I towed it to mazda to see what the cost is and they estimated about $5100 to fix it. I am trying to find someone local that can do it for cheaper. I was figuring if the price for new internals was close to aftermarket, I would get aftermarket ones instead. I have a short video clip of the incident.

I think I hear detonation....

hehe well that doesnt tell us much...got any aftermath pics of the engine...how did it blow...did it blow a ring or send a rod through the block? I'm assuming from your description it was the latter, which basically means you're ******....you'll have to get a whole new block at the least.....that sucks man.....what psi were you running day to day?

 

[low_psi]

damn definately get forged internals for your new motor and some engine management... how much boost?

 

[RyanJayG]

damn... though internals aren't going to fix your problem

just find a boneyard FS shortblock (a later one, so it has the casting updates and forged crank) and build it with forged stuff... WAY cheaper than what Mazda quoted you...

 

[mp5jeff]

buy a new short block with forged internals...

 

[mp5jeff]

nevermind ryan beat me to it

 

[mp5jeff]

btw you can get a shortblock for a few hundred bucks from a junkyard.

EMS>forged internals

but if you've got a motor open

 

[igdrasil]

Been there man...it hurts...

Get a spare motor...MPI or any other fuel/ignition management unit and forged internals

Motor ~$800
ECU ~$1000
Forged Internals ~$1200

I get the car back tommorrow, I will take some pics. Yes I busted a rod through the block. There is a big whole in the side of my engine. I was boosting 12psi with 93 octane gas. If you listen close on the video, it sounds like something was rattleing around.

 

[RyanJayG]

oh, trust me.. you DONT have to "listen closely"

also, the AEM EMS will be available from MAM soon... you might want to consider this option as well.. full plug-and-play

 

[hello2000]

lol

 

[mp5jeff]

that rattling = detonation = you should let off the gas

 

[hello2000]

I think once I get this fixed, I am going to get out to the MSP performance all together and use it as a daily driver. I just can't afford to suffer this loss.

 

[RyanJayG]

if that is the case then dont bother with forged internals, just find a shortblock under 30k-40k miles

 

[hello2000]

What do you think guys? is it worth it? If i put the forged internals in, would the engine be more stable?

 

[RyanJayG]

not at stock boost levels.... not necissary...

 

[hello2000]

Is the engine block the same as the regular 2.0L Protege?

 

[mp5jeff]

yes
