Engine Rebuild Cost? -- Answered Thanks!

[angryBits]

Trying to see what the worst case scenario would be if I mod my engine and it decides to explode. What cost would I be looking at to replace/repair?

Imagine something like this: ZL1 Engine Failure.

Definitely have to replace the block, pistons, connecting rods and pins, everything else like the supercharger can be reused to save money. Not sure if they do that.

MSRP on a new LSA engine is $14,000 @ LSA Crate Engine.

MSRP on a new LS3 engine is $7700 @ LS3 Crate Engine.

So I'm guessing parts will probably be less than $7000 plus labor.

Does that mean maybe it could be repaired for $10k ? Thoughts?

Update: Someone PM's me with helpful details -- seems my guess of about 10k is a fair guess. That's all I was looking for. Thanks everyone for the help!

I dont think your KR issue is that bad is it?

Hahaha!! You're right it's not.

I don't want to spin this thread in that direction, thats why I created a new one. But to answer your question -- I'm actually considering getting a tune and potentially risking the warranty.

My reasoning is:
If I trade the car in on another car to solve this issue (which my wife has already said I can do) I will likely lose $10k tomorrow due to depreciation.

However, if an engine repair without warranty costs close to $10k or less, then I can get an aftermarket tune to fix this issue without worry. Because its likely nothing will happen to the car, but even if it does, I'd spend $10k and have a new engine and I would have spent that on a new car anyway.

Anyway, please lets not everyone give me $#!T about this logic, I really just want to know what it would cost to repair so I can justify voiding the warranty with a tune

Thanks!

Actually... Now that I think about it. This is a great question for the dealer.

Ok, I see your logic now.

You need to verify that your noise is in fact spark knock. KR does no always result in audible knock. More often than not, it isn't audible and can't be detected by human ear. I would not be so sure that you are dealing with spark knock. It is very difficult to detect for certain. You need to figure out what you AR hearing before having it tuned.

Does it go away with octane additive?

There is another thread that talks all about the knocking, dealer has verified and confirmed knocking.

This thread is about rebuild cost.

That engine was a complete loss and would not be worth the cost of rebuilding. A new long block would be the way to go and would be less than a crate engine.

Right. I don't imagine the lock is worth anything but scrap metal.

But the supercharger, heads, fuel system, all that should be still good and shave a lot of cost off the price of a new crate engine.

I'm thinking if the estimate is less than $10k - 12k then its worth it for me to just take the risk.

I'm not sure I follow. You're thinking of ordering a long block?

[Chrispy]

I'm normally a very laid back person but let me get this straight...you are looking at buying a blown up long block because you're worried about a few degrees knock retard that you may want tune out because you don't want to buy Torco?

Your logic is fu@ked man. Seriously...

You could run that car on 91 Cali gas for 200k miles with regular maintenance and it won't die...

I think you misunderstood.

I'm running a worst case scenario analysis to decide what the best route for me is. I would never buy a blown up engine -- why would anyone do that? I'm not even going to buy a new engine.

I'm just asking: "What is the potential worst-case-cost if I decide to void my warranty?"

I don't want an engine that wont die. I want a healthy engine that I can mod the $#!T out of. An engine that doesn't knock.

... I seriously need to change the original post so people stop saying stuff like this...

EDIT: I clarified the original post. Lets please stay on topic

Have you put an octane additive in your car yet?
