Blown Engine Resource Thread

[TyphoonFiST]

Previously had a ring land failure (cylinder 4) with an X47R, aux fuel, mishimoto radiator and ethanol tune. Just to note I was experiencing overheating in the middle of the summer in Arizona while running the car stock PRIOR to modding the car. Bought and installed a mishimoto radiator which solved the issue...then began modding from there. I rebuilt the engine with forged pistons and rods from mountune and everything has been goochi. Beat the piss out of her with the stock turbo for six months.... and now I'm back at it with an upgraded S280 turbo .

What were your failure symptoms with the x47R? What led you to believe it was ring land failure....Etc.

No symptoms, just flew off a chunk of piston during a pull and began eating oil. It threw some code that I do not recall but I ended up looking at the spark plugs and seen oil on the spark plug for that cylinder. Pulled it apart and found that.

How much would you sell me that piston and rod for?

Reading through this thread I was like man idk if I wanna continue modding my FiST. Then I was noticing some things throughout the thread what years were mostly affected, and how many I had seen I was doing a hard pull when it happened. So with that being said I suspect some were due to LSPI, and some were the 14-15 models with overheating issues. So I'm gonna continue my modding journey and enjoy, plus used 1.6 eco long blocks I have noticed can be found for relatively cheap.

Also gap your plugs closer to 020-.022.

 

[Quisp]

A wider plug gap exposes more spark to the mixture.

Also, small gaps are more subject to being closed up, shorted, by deposits or other foreign material lodging in the gap.

Big turbo smaller gap. If you’re driving a
race car running at high rpm constantly, then a bigger gap is what’s needed.

 

[TyphoonFiST]

It goes Big turbo W/ High boost = Smaller gap

Boost over 15lbs Gap= .018-.024

Boost under 15 lbs = .028-.032

Or play with the gap setting to see what your car likes

The next thing you’ll be doing is telling everyone about Brisk Racing Silvers

More details would be nice. Turbo, tuner, mileage, what occurred before it blew? Failure mode, etc..

Not nearly enough information being provided. Starting to sound like a troll. Also very bizarre first post on the forums..
