There are a few cam related issues listed in the Recall Thread but this is the one I was mainly talking about however they all seem to be related.
One fix is a shim, @s2d4 mentioned a part change that I am not aware of and want to know about. If there is a fix I want to know.

This user had a turbo setup and had a similar issue.

Im the same.

Seems like boost is evil.

Im going back to trolling the prom thread.

I've recently had the motor go on me
Sprintex Supercharger running 70mm pulley on 95rON.
Prior to the engine failure I had the following codes over a 6 month period.
PO351 coil pack
Po372 (I think it was this code for Cam position)
PO300 multiple misfire
At the time of failure I happed to be logging, indication is too much boost (.8 bar) on 95RON.
Busy with rebuild.

Thats like getting on a flght thinking you could crash.

There are many FA20's running around with no cam timing issues.
I would be more concerned in trying to find out exactly what happened instead of saying screw this, time for another motor.

Imagine if you got an LS7 and something happened to the factory dry sump...
Does that make all LS7's bad?

My issue is those that had it fixed there was no real parts replacement I was told by the tech so I could face the problem again and being boost when that happens it will result in the same problem if not worse should it happen while I am racing and not just driving normally.

If I could trust the FA20 I would just put in another and shrug it off as a fluke as I seem to face many strange situations. But at this point I do not know that I can.

What's the stock pulley on the sprintex? Too lazy to look it up

Also do you have pics of the failure? Did the block just crack or what?

Sorry for your loss And to think the sprintex package is one of the more tame ones out there.

How do u overboost with a supercharger? I'm thinking it was poor quality fuel that caused your failure or a lean condition

75mm pulley is standard for IC version.

The block is fine, melted piston.

I never said over boost, i ran too much boost for the shit fuel we have here.

Add me to the list plz :-(

FBM stage 1 premium kit(one of the first, bought september 2013) with all te bells and whistles, GTX30, base map customized by LJ.
Mileage around 1000 miles, ran fine and strong until 2 days ago. After 5 km power loss, E/G knock and finally a lot of smoke. First cylinder rod snapped and knocked a hole in the block.

Had a few small problems with the kit from the beginning, but I have to say top notch service from FBM solved every single one of them in reasonable time. Reported failure @ mail LJ last sunday, received reply yesterday and I'am sure we're working things out as always...

I suspect fuel conditions here in Europe are different than in U.S. I'am going for a fully built block now but before it will run one second, I will bring it to a Subaru and ECUTEC specialist... Pretty sure starvation/running lean lies at the root cause.

Man this poll is scaring me. As it is now only 100 people who have (or had) FI have voted. You have a 1/10 chance to blow your motor when going FI. 10 votes for yes I have blown a motor and 90 for I have not (have yet) a motor.

Making me think twice

this thread made my decision for me. 1 in 10 or 1 in 100 is not worth it. good luck to anyone that does it

I'm thinking Phantom Electric Supercharger after seeing this thread. They look like fun. Will use that, because I believe it is safe for stock motor, until I can afford to build a block.

And more importantly, Until I can afford to replace a block if necessary.

Out of all of the blown motors out there. How many people regret going FI and how many loved it, despite the short run at it. Guess im asking if you could change it, would go back in time.

Why are people running their cars without WB with FI???? I don't get it.

If you have FI in any car, you should be running a WB and any time it starts to go lean, you stop and figure out the issue.

Run FI in a car with a 12.5:1 CR and no WB, you're friggin crazy....

Jaden

^------buying WB before even tuning the non FI car, let alone once I go FI...

ok. I might run a shiv tune before having WB...but not for very long though...

Are you just running around making ignorant posts to raise your post count or something?

Where are you pulling this crap from first 21k out of thin air and then that people are all not running WB's....
