SR20DET Knock

[Little Jason]

Hey guys,
I was cruising down the road the other day when my car cut off, after a few minutes i tried to start it back up, and it was running super shitty and bouncing between 300-500 RPM's. It was also knocking really bad. I'm pretty sure that it's a rod knock, but I'm not 100% sure yet because I haven't really checked it out.

But before I get into anything, if it is a rod knock, I need to figure out what to do. So I'm wondering your guys opinions, should I actually rebuild it if it is a rod knock, or should I just get a new SR and drop it in? I'm sure it would cost more to get a new SR, but I do have a little money saved up, so would it be worth it to just buy a new one?

I'll apologize before hand if this is a shitty thread, but I've never really done anything with engine internals, which is what made the new SR cross my mind.

Rebuild it. All new shit > used shit at A probably cheaper price depending on how long you drove with the knock

It hasn't been driven at all with the knock, when I heard it I got a tow back to my house, I was only about a mile down the road lol.
Only thing I'm worried about for rebuilding it, is that I've never done anything internally to an engine, but thanks.

Cheaper and less time consuming to swap in another engine. But like already stated, getting it rebuilt will be better for the long run. Question is, what killed the engine? If it just died and then when you started it up, it started knocking, almost sounds like your oil pump died.

Have a shop rebuild it. Brooksville is pretty close to Z Fever, S&R Performance, and Lutz Performance. All reputable shops. I've seen too many people try and rebuild SRs by themselves with little experience and it ends up knocking again on startup.

That sounds pretty accurate actually. A couple days before all this went down my oil light was flickering for a minute, and I didn't really pay any mind to it because it stopped after a few seconds. Sounds like I should have thought more about it, lol.
