No pictures yet, but two days ago I discovered the front axle locker on my '91 Blazer was faulty when it somehow slipped from disengaged to halfway engaged as i was doing 70 on the highway. Surprisingly, I didn't hit the windshield, but there was a godawful metal on metal screeching sound combined with an incredible mechanical whirring coming from underneath the car. No visible signs of grenading, and it still moves forward just fine now that I have disconnected the locker cable and made sure that it is disengaged. I'm taking bets on what I'll find in there once I open it up.

Edit: There was going to be a picture of a horrible mechanical failure here, but imageshack's android app is a flaming pile of poo poo, apparently. Edit 2: Or, upon further reading, imageshack and SA used to play nice, but one day imageshack took it's ball and went home.  In conclusion, this post contains a horrible failure, but not of the mechanical variety. Soodonim fucked around with this message at 01:22 on Feb 6, 2014 |

Previous owner had installed a catless downpipe. As I've since learned about the MS3, if you install a dp without upgrading your hpfp, you're going to have a bad time  All better now though!

Surely a tune would be all that's needed? Free-flowing exhaust will certainly make the turbo spool faster, but if the wastegate's working your boost shouldn't peak any higher than before?

45,000km's since the last oil change. We quite literally took all the covers off the engine and the engine out of the car, then proceeded to chemically waterblast the poo poo off the engine. New valve stem seals to stop the oil consumption, back in the car and he's on his way to the nearest dealer to do a trade!

A bottle of Seafoam will clear that right up. Spinning a rod bearing just from installing a downpipe seems extreme, and how would upgrading the fuel pump have helped?

Fucknag posted:Surely a tune would be all that's needed?

Correct, but I didn't know any better until I started researching why my engine blew up. I now know a poo poo ton more than I did (rebuilt the engine myself in my garage), and I have found ample evidence that the car was heavily modded before I bought it. The dickhead mostly stocked out before he sold it. He left the dp because they're a motherfucker to swap on these vehicles. Hpfp internals are a quick swap, so I'm pretty sure the rear end in a top hat put the stockers back in and knowingly sold the car in a compromised state. It's amazing that it lasted as long as it did. Oh well, live and learn. Now I've got a built motor with forged internals, I'm self-tuning, and I'm on my way to 350 whp. I've been having more fun with this than any other project I've ever undertaken, though it was terrifying at first. I owe it all to that piece of poo poo douchebag in Fishers, IN that I bought my Speed from

Snowdens Secret posted:A bottle of Seafoam will clear that right up. Direct injected engines inject a very finely atomized mist of fuel directly into the combustion chamber, using pressures in excess of 1600 psi. When the engine breathes so much more freely due to a mod like, let's say a catless downpipe, the stock high pressure fuel pump can't flow enough fuel at WOT. Pressures drop dangerously low (below 1000), compromising atomization and creating a lean condition. To make matters worse, the ecu can compound the issue by increasing the injector duty cycle to try to bring AFRs back down, which in extreme cases can cause puddling in the combustion chamber. Knock, knock, boom. Bent rods, spun bearings, vented blocks. I got off easy and was able to salvage my block and crank. Like I said, it's amazing my engine lasted as long as it did. After I got my engine back together with upgraded hpfp internals and bought an accessport, I discovered that I was spiking over 22 psi on the stock tune, which targets around 15 psi.

Ah, see, I thought you were saying the downpipe was all it had. Like I said, the downpipe only makes boost come on sooner, peak airflow won't be any higher than stock so the stock fuel pump would keep up just fine. I bet you, though, he had the boost cranked way up, and that will max out the injector duty cycle (or HPFP in your case), and you get the detonation, etc., which is all the worse due to that higher boost. Not to mention if he's pulling stuff like that I bet he never had a proper tune on it at any point. Once the bearings get a little bit hammered, the clearance is wider and oil doesn't fill the gap quite as well as new, so you get a feedback loop which is you how spin a bearing 3 years down the line.

Not to mention if he's pulling stuff like that I bet he never had a proper tune on it at any point. You've mostly got the idea. But believe it or not, a catless downpipe by itself will cause massive boost spikes on these vehicles, even if the ecu parameters haven't been touched. Also, to unmarry an accessport from a vehicle (which you have to do if you want to sell it), you have to take it back to the stock ECU map. The K04 turbo spools like a mad bastard under any circumstance (I have logs that show IM pressure going from vacuum to 22 psi in about .75 seconds - what turbo lag?). The stock exhaust has two catalytic converters. Throw on a catless downpipe that deletes both, and the turbo spools and builds boost faster than the stock wastegate compensation parameters can deal with. Stock tune targets 15 to 16 psi of boost, I was hitting 22+ every time I mashed the pedal. I had to cut wastegate duty cycles to less than 50% of the stock parameters to bring the boost spikes under control. Like I said, it's a loving miracle my engine lasted as long as it did.

Ah, see I wasn't aware the MS3 had any electronics in the wastegate setup; my MSP just has a straight vacuum line (also a much smaller turbo running way lower boost).

The DISI MZR is a special snowflake that requires performance parts typically be installed not only correctly but a certain order. It seems like Subarus are not nearly as finicky engine wise and usually outlast the clutch/transfer case.

I would expect there is an electronic boost controller in there. Probably a 2-port with a restrictor pill. The ecu maps are kind of funky on those as I recall and tuning them is a lot of work. Or at least it was a few years ago when the accessport was being developed for it. I think I can get c-pe stuff, they were making fuel pumps last I checked.

Lower boost, yes, but the MSP turbo was actually gigantic. The MS3's turbo is about the size of your fist (or it was the last time I looked at one, which was in 2007-ish)
