Why did my engine blow?

[hello2000]

I am trying to figure out why my engine blew. I talked to another guy I know and he's puzzled too. He has a talon with a 2.0L turbo charged engine at 28psi with a SMIC. Here was my former setup:

HiBoost FMIC
JoeP. MBC (12psi)
AEM CAI
and everything else stock.

any ideas?

No exhaust, and no tuning. Throw on top of that some weak rods and you have your answer.

Thats what I thaught. Do you think the greddy e-manage would be a good choice. I'm kinda on a limited budget.

[gboromsp]

I think it is a great choice. However on a limited budget go with DSM's AFC, I am running it, and it it excellent. And for roughly $300 you can't go wrong. Also make sure you get some sort of exhaust, if it only a midpipe that is better than nothing.

E-manage will not work. The ECU will over ride it's tuning over a period of time. Unichip and MPI are the best. Haltech or Microtech stand alone if you live in a non OBD2 state.

Also, as you may have already heard. It is not too wise to use the FCD and JoeP MBC, especially at 12 psi.

[BlkZoomZoom]

and in 5th. gear....

User error is why it blew.

Emanage does work now. People found ways around it.

Like everyone else said, no exhaust no tuning, and I agree with BlkZoomZoom if you were in 5th, or ever boosted like that in 5th.

so you saying i can't boost 12psi in 5th gear??

[BlkZoomZoom]

you blew the motor, you tell me.

[SP33D]

i was in 2nd gear on stock boost with just a cold air intake and my engine blew. our motors suck.

[Super Matty P]

I've said it once and I'll say it again. "FS-DE's rods are so weak you can fart and bend a rod"

[peepsalot]

Group buy on Butt-plugs anyone?

[hello2000]

will not putting synthetic oil blow the engine?

[BlkZoomZoom]

yeah that will make your rods bend.

[mp3moose]

Yeah, 12 psi and shitty rods are not your friend. We've know that since early mp3 owners went turbo.

[hellcat]

MP3Moose, go to ******************************* and check out their built short block. It could be the answer to your problems.

[mp3moose]

Oh, my block is fine. My low, NA power isn't enough to bend rods, at least not the way I drive. If I was boosted though I would already have a built bottom end.

Not true you need a O2 modifer (flying miata or essential speed) the greddy O2 modifier is like $80. once the car hits boost (set RPM) it will put the car in open loop rather then Close loop.

Cheap alternative my Greddy emanage cost me about $300-400 for everything. I just need it tuned. im missing an ingnition harness and thats about it. I was turned off by unichip becasue of how hard it is to get a custom tune. its hard to find a unichip tuner. Theres like a lot of shops that know how to tune emanage. They are comming out with a 2nd version of emanage which is said to have more features. Plus a WB O2 kit which I heard will allow for an auto tune and more percise private tune. Unichip maps are made to 50 state legal...and depending on where you live conditions are different....thats why I wanted somethign more customizable.

You blew your engine due to lack of tuning. We dont drive DSMs and we dont have a 4g63. its not like we can boost like 20 psi off the bat with no tuning.

oh and a good tune that know your engine well. Unichip tune is one of the best pretuned you can get. it spikes at 12 and bleeds to like 9 at higher RPMs to provide a better barrier. You do hear unichip users blowing their engiune but not much....not much at all.

Get some fuel managment to be safe.

[Brian MP5T]

YOUR RODS! End of story...

[Sveivo]

We dont drive DSMs...
So DSM motors are stronger?

[MSP#735]

damnit i hate our cars (well today that is) that good ole love hate relationship!

If its a GS-T motor a proper Force induction motor. A motor built for boost not NA.

[acidbbg]

I am pushing 12psi...on a slightly larger turbo than a t25...the reason why i have been able to do so..with success..is b/c of EMS. The MSP..seems to knock..whenever you turn up the boost..something to do with the fact they added timing...when they issued the reflash...

[spacemonkey]

the knock I think is from a shitty intercooler. the intake charge is not really cooled thus the air going in and mixing witht he fuel is already hot. on top of our thin rods and cast iron parts it can only take so much. Cars taht are boosting 5-6 psi arent exactly a problem since lots of set ups dont even have IC. but for anythign more like 12 psi your compressor is getting hoter and thus the air comming out is hotter and with a intercooler that is already heatsoaked its not good. our cars were engineered for 6 psi.

Actually give your engine credit for lasting that long while under knock/detonation. its not a bad engine if youre smart and know what you are doing. Blackzoom mush have beat the crap out of the engine for a long ass time before it went.

will not putting synthetic oil blow the engine?


Did anyone else see this post? I think we have our answer here. Prolly used 87 octane too @ 12psi

[BlkZoomZoom]

yeah that will make your rods bend.

not using synt. doesn't cause your rods to bend.

[Dexter]

wtf. yes you need synthetic or omg yuor block is poo!!1

[Nextruss]

along with supporting mods, (not neccessarily EMS) will just replacing the rods/pistons create an ungodly, boost happy engine? So you could handle 15+ psi? Or whats bound to break if your pistons and rods dont.

[BlkZoomZoom]

We'll find out this year.

[hello2000]

Did anyone else see this post? I think we have our answer here. Prolly used 87 octane too @ 12psi

No i had synthetic oil when my engine blew with 93 octane gas.

[Leadfoot]

another interesting note....you didn't have colder plugs? Colder plugs will reduce the potential for detonation....my first mod on my otherwise stock MSP (although I have had 13psi & an Injen on...but they are off until I complete my FMIC project).

This is not true I have been running E manage for a very long time. It's running great.

I am trying to figure out why my engine blew. I talked to another guy I know and he's puzzled too. He has a talon with a 2.0L turbo charged engine at 28psi with a SMIC. Here was my former setup:

HiBoost FMIC
JoeP. MBC (12psi)
AEM CAI
and everything else stock.

any ideas?

You ran 12 psi with no exhaust or downpipe. User error and ignorance is your answer.

are you serious? 12psi with a fmic and otherwise stock setup and in fifth gear.

please tell me you're kidding.
