broken crankshaft bearing
alright need help from the engine experts lol.
so in late May, one day i had a squeaky belt sound. the next day i took it in to a garage and i had a bad crankshaft pulley, got it replaced and it wasnt wobbling anymore.
then, i got a bunch of engine work done this July by a friend and he said it was wobbling, i said i got a new pulley in May. he said he would look into it more when i brought over all the suspension stuff in August.
he looked at it and said everything is tight, and that my crankshaft bearing is gone. is this that hard of a fix? hes trying to find a fix for it now, in moist conditions its not squeaking but constantly theres a sound like if you run your fingers across your keyboard. the sound will **** off after about 3k RPM. engines got 425,000km on it so im just guessing time has caused this right?

you're sure it's not a broken crank snout?
the crankshaft bearing doesn't exactly get "broken"...it's usually worn out...unless you blew a hole in the side of your block.

what these motors are prone to do is break crank snouts...but your guy knows better than me i guess.

good idea to start saving up for another motor now...you might need it.

anywho i'll just garage it for a bit until i figure things out, its either i fix this engine and boost it or just grab a Z31 VG30ET. i can walk to work and such but i might have to grab a 2nd car sooner than i thought
its pretty much wobbling like this

to be honest...if you're having doubts on changing a crank pulley yourself then you might not want to boost your own car.
no one online can teach you how to turbo your car. it's all learn as you go. that usually means more $ that's needed to learn what you need to do.
you know how many mandrel bends i had to toss to get a working set up? how many late nights welding and at the same time trying to hone in on my welding skills. then learn about turbo and what's ideal. looking at what OEM turbo set up looks like. let's not forget about the plumbing and adopting all that to a motor that wasn't really set up to have a turbo in it. you'll get to learn every aspect of thread pitch, bolt length, flares, etc that you wish you just paid someone to do.
this is all before you even turn the key on the motor.
for a lot of you guys this is a car that's either handed down or you bought for very cheap. this might be your 1st car and you might have some attachment to it but don't come on here to claim that you're going to do XYZ when you don't even know how to do the simple things (not saying just you chrome). if you done your own timing belt and the car didn't go boom then you're on a good start. if you haven't done that then don't even dream of building your own custom turbo kit. this hobby requires dedication and some aptitude on how to turn a wrench w/o stripping a bolt and a ton of time and money. if you're lacking on any of these then you're setting yourself up for failure.

no it sounds like a rubbing, before you could only faintly hear it every 2 seconds on idle but within the last week its gotten constantly loud but its got the same amount of wobbling
someone i know is coming over to see it and check out if its the snout, if its truly the snout and you think its time to give up i may just see it crushed because i would never want to see it parted out, i would just take out the Sparco's and stuff and see it crushed and move onto a Skyline GTS-T or a Cressida or something.

who knows though it might be something simple and maybe not the snout
EDIT- NVM i talked to my parents and if its the snout i can park it at their other house and just by something else for the meantime then figure things out

for starters my uncle came over to show me his RX8 and took a look and he knows some people who rebuild engines so i'll call around Monday and see how that goes

i guess it'll be going in next week, i need it back fast now so a garage i know will give me a deal and source a low mileage engine. im just disappointed that the timing belt and all the other stuff was done to my current engine just a few months ago and now this happens

That stuff can easily be swapped over to the new engine. You'd want to do that to the new engine being installed anyway. Imagine how much easier it is to do that with both engines out! And on the replacement engine, go ahead and replace the front/rear seals as well as cam seals just to be safe. Ohm injectors on new engine....if any need replacing...just swap over your entire fuel rail. Easy stuff.

If you have "new" parts, then yes, I think it's worth it. The timing belt I personally go either way. On one hand, if you have a new one....I'd tend to swap it over unless I knew the one on the replacement engine is better. On the other hand, a new belt from Nissan costs $25. So, if I ever have a question, I spend the $25....that's also why I have two belts on my shelf that have less than 5k miles on them.

Cores are required for rebuilding. Heads, cranks, blocks, waterpumps. Anything else goes in the trash.

engines still good, AC belt was having problems which is why it was horrendously rattling. the crankshaft pulley still has a wobble but they said its fine for quite a while so hopefully when the time comes i can drop in a new engine myself
