any one know how this guy ended up detonating his engine... was it because of his turbo...hmmzzz...getting second thoughts of turboing my 5sfe...

[itzsteven]

it's ufo's car.

[CamryPunk]

Yeah, it's POS cuz it's taking up room for MY car to be fixed.

[prnc_chrmng]

you could always ask him...i think he hit a spike of 15 psi and there went the engin

[mescalito]

his boost controller malfunctioned and it caused a pressure spike and the 5sfe couldnt handle it without forged internals....i'm pretty sure that's what happened anyways


edit: facts straight

[DarkMastyr]

I've heard nothing but good about Hallman MBC's and many things about the unreliability of EBC's, especially during the winter when the temperature starts affecting the electronics (variability in wire conduction, etc.), unreliable boost readings, unreliable boost controls, and such. At least that's what the general consensus is among Mitsubishi Evo owners. You can search over at www.evolutionm.net if you don't believe me. I believe I've heard about some issues regarding TurboXS MBC's, but I can't recall exactly what it was.

okay so all i need is the right parts and accessories and rebiuilding my engine the right way...and i should be good to go with a 5sfTe

At the time I was running a Turbo XS dual stage manual boost controller (piece of shit). Low boost was set to be at 8psi...

Then the unthinkable happened, my boost controller malfunctioned and boost spiked up to around 15-16psi. Kaboom. I started hearing rod knock immeadiately afterwards AND threw out my stock clutch in the process.

This is why Justin refers to manual boost controllers as "death knobs."

If youre going turbo... Spend the extra cheese to just get an electronic boost controller or just use the stock wastegate setting.

aaahhmmm ... I wonder who tuned your S-AFCII ??? LOL... And made boost come on at 1500 to 2000 rpms instead of 4000 ??? And all that trouble shooting in your car and told you not to install that 'Death Knob'.... LOL just messing with you Allen

^ Nice if you can get your car out there... hahhaa I'm JOOOOOKING Allen.

Lemme drive your scepter when it comes out.

[vsixcamry]

ufo is the king of the 5sfe. I like his taste too. After he gets it back up and running he will be the 5sfe .

[CamryPunk]

^ you can drive my civic. hahaha.

I"m not going all out like you. Just a rebuild, new pistons, piston rings, seals, rework new piping and new BOV, and pretty much clean everything up before sticking it back into the car.

Haha, "deathknobs"... I like that

Usually this would have been prevented with some good tuning... Even when I was running E-manage, I was able to retard the timing and dump fuel at higher PSI maps . All boost spike would do is give a nice backfire and no harm to the engine. Without proper mapping in the boost region, you are looking for trouble even if you are running base wastegate pressure. It is hard to prevent annoying things like a cracked vacuum hose, or a hose popping off, etc... to cause a boost spike.

So it's good to learn from that and blowing up a tired old stock motor rather than blowing up a fully built one.

Hey Allen, any updates on the progress?

[dna59]

can't wait for the car to come back out.
