Default Spun bearing ej20

Well recently spun a bearing in my 2002 wrx. How reliable are 2.1 stroker motors. I see steamspeed sells a whole kit with mahle pistons, manley rods, and ACL Race Bearings. Anybody have an experience with this setup. I'm not looking for crazy Hp just looking for a stronger motor for the future if I go 20g.

I wouldn't think that they are any less reliable than any other forged engine. I think the reliability comes when you start to run like 24 or more psi of boost. and the machining of your block.

it would be just as reliable as the build, tune and maintenance like any other engine.
Plenty of built motors with expensive quality parts on this board have blown up/had problems with less than 3000 miles due to some part of the build not being just right.

Do an oil change. If there is metallic flake in the oil coming from the filter, then you've most likely spun a bearing. I recently spun one a few days ago and the oil change is what made me know for sure. It looked like paint you'd see on a car, tons of copper flake floating around.

you "spun a bearing" in your turbo? I'm fairly sure that's not something you can do. You can have trashed bearings, but they aren't like rod bearings. They're either journal bearings or ball bearings in a housing.

so if i do find flakes in the oil then the motor is scarp. right? which would suck really bad seeing as i have had the car a week and a day when this happend. I never really even pushed the car that much. I had asked a friend of mine that owns a shop and his mechanics said that what i described sounded like a spun turbo bearing. said that it probably slung chunks of metal into the enigine. Now I am new to turbo cars and am learning the do's and don'ts. Am extremly sad that my first snail powered car died after a week. And without even being mistreated. The WRX drove amazing. Had a little vibration 60+ mph. had all tires balanced, and then was nice and smooth. That was the only issue up until the horrible sound of chains being thrown into a woodchipper. I had stoped by a friends for a few hours and when I got in to leave it started....ran for all of one second...... bad bad sound...... and died. i turned it over one time softly.......... bad sound. left it. had my wife bump it with my head under hood to pinpoint the location of said bad bad sound. And it was right where the turbo was. Then i hit the web for answers. so if not the turbo taking a nice big **** into my engine.... what could it be and how much is it likely to cost me? i have priced a complete engine. and am thing of just doing a swap until i can have it tore down. but hopefully I won't have to. any ideas or advice would be great thanks to all that reply

If you have metal flakes in the oil, it probably also passed all those little metal pieces through your turbo as well. Pull the motor and have a look at what has been damaged.

An EJ207 v8-9 is a good swap option.

you can certainly destroy turbo bearings, it probably doesn't result in a whole lot of metal. So options are replace turbo, see if it's happy times, or pull motor and and see if rod/main bearings are trashed.

But a car should still run with a bad turbo right? Rough no doubt but should still fire and run. I get nothing but a sound that makes my stomach hurt.

yeah it should still start at least. It would run pretty poorly and it should be putting smoke out the exhaust. Of course the problem is that lots of metal particles will be moving around the engine causing wear to parts. maybe make a recording of it and put it on youtube to link to us?

I will do just that. The car is still at my friends house so it will be sometime tomorrow before I am able. The video will be fairly short though. I don't want to do any more damage than there already is just in case there is a chance it can be saved. Thanks for the great idea and keep a look out.

Drop the the downpipe and see if your turbo is dead. Try checking for shaft play. You can also pull your turbo inlet pipe and see if the blades exist or scraping against the housing.

It sound's like you have no compression or a starter to flywheel issue,.. if you can turn the motor over w a 22mm socket at the crank and it starts look into the starter or flywheel, otherwise pull a timing case cover and start suspecting your belt~ GL
