Spool Turbo MP3 Blew Up

[igdrasil]

Hey....

This are my Actual Plugs when me engine blew!
Check the left one...looks green, very green!!! = DETONATION

 

[LinuxRacr]

Wow Ig! (eek2)

 

[TurfBurn]

yeah... that's definitely green! LOL... wow... nifty. I'll try to at least get pics of my plugs tonight!

Later.

what causes the plugs to turn green?

 

[TurfBurn]

That happens.
If the injector get stuck open, failure may happen because there is not enough lubrication on the cylinder walls and cause enough heat to fry the rings.

Or the worst environment, too much fuel injected, spark failure, cylinder shutdown starts to get drown in gasoline fast...locks it and the rod bends.

I was largely having a hard time wrapping my mind around getting so much fuel in there that you'd be able to fill the clearance area above the piston with fuel to hydrolock the system. But definitely follow you on the lubrication and heat issue. I just want to tear into the motor so bad so I can find out what is up... but just don't have time!

 

[LinuxRacr]

what causes the plugs to turn green?

The engine killah! A.K.A. DETONATION!!! (eekdance)

 

[TurfBurn]

I think he means what physically causes the green color... aka metallic oxide deposits or what. (or at least that's what I want to know! )

 

[Matthew]

what turf said.

 

[LinuxRacr]

Not what Linux said...:'(

 

[TurfBurn]

It's ok Linux, we all love you anyway! Especially the cute flapjack hopping bunny

 

[mazdaspeedpower]

Congratulations on the need to rebuild...seems like that follows your optimistic philosophy on this situation. lol. Also, if you where running extra rich, could you not have dumped enough fuel into the cylinder to creat a big enough 'bang' that it was more than the rods could handle? But I'm not really an expert, this is just a rookie guessing..lol. I don't see hydralock being the issue, but you never know till the pieces are infront of you. Also, maybe the rods where and pistons have just taken so much abuse, through having high power, the occasional knock, that they where weakend, and they finally just gave out. Oh well, you'll fill us in whenever you get a chance to tear the beast apart. Good luck, and have fun

 

[igdrasil]

Yeah!

I may try an "invention" IF it works:

"hint"

Will try use stock piston/rod from 1.8L protege, It just need some work on the rod to fit in the crankshaft.

 

[TurfBurn]

I was looking at the FS-ZE engines and pondering that as my "interesting" option... Don't know the ups or downs of that engine yet to know if I want to do that or not or what benefit it would have.

 

[low_psi]

higher compression: 10.7:1, agressive cams, better intake manifold, possibly larger dia. TB. that's it I believe. Linux should chime in here soon.

 

[TurfBurn]

Hmm.. if it's that much higher compression that may not be the best option for staying with my turbo.. but if my turbo is screwed... maybe I can go NA or something.. dunno! It's an option at least.

I also found that mazda motorsports now has an intake AND an exhaust cam available for the protege. they lobes aren't ground from what I saw.... but they are there!

 

[LinuxRacr]

You pretty much got it. Oh, and that's agressive CAM (singular). The intake cam is the only different cam. There is the JDM Mazdaspeed exhast cam that is an upgrade. Our stock cams suck. The FS-ZE intake manifold requires some modification to work without CEL's.

 

[low_psi]

thanks for clearing that up!

The new exhaust cam:

</TD><TD vAlign=top align=left colSpan=6>USE FS9P-12-440A Higher performace cam from Japanese market MP3. Additional horsepower numbers not yet known. Use in conjuction with FS9H-12-420 intake cam which adds approximately 12hp. NOT SMOG LEGAL. This cam is modified from an intake cam, and therefore does not have a drive gear to drive a distributor. So.. This won't work on earlier 2.0 liter engines (626's) with a distributor.


</TD></TR></TBODY></TABLE>

But if the intake manifold's only major issue is the CEL thing that'd be just dandy with me and the Microtech. So something I'll have to keep in mind for sure then!

 

[PaulMP3]

damn.. glad your taking it so well. I have been running 12psi for a while now on stock internals.. Im gonna turn it down to 8psi or so untill i get around to building my spare block. I cant really afford the down time and inconvience at the moment.


good luck and have fun with the rebuild.

 

[MPNick]

hot rods always run their bets before blowing....

Why is this so true. It seems that by the time you get it to run the way you want the damage is already done.

Thanks again


Later.........Nick
