So they haven't raised their prices because S&H is ~$300

Yep. Charperbuilt went with NSC through them though. I believe it has better properties overall. He did a lot of testing on these builds to determine what was going to work best.

Also keep in mind that price at Millineum is if they do not have to repair badly scored cylinders. If so, that costs extra based on people I know that inquired.

So, for a seized-up engine, you are looking north of $7500? S&H and taxes included?

Thanks!

Not sure the actual price but likely so. I guess it depends on the extent of the block damage. I know Charper sells his rebuilt, NSC coated short block assemblies for $5900 but that is with a good core. So yeah, if the bores required repair that price will climb quickly.

But if the mains are spun it is pretty much a paperweight as it will shred the lower block and cradle. I dont see that being fixable. So for an actual seized motor it may be beyond repair.

No matter what, there is no "cheap" option on these motors! And when/if honda adds the s2k to the parts program I expect we will see pretty steep prices on short block assemblies there too.

Sad. I guess at that point, start looking for another car.

We tore down my friends that spun 2 main bearings last year... was a sad sight.. we were REALLY hoping for just some rod bearing damage since he shut it down quickly after the oil light flickered but it was still too late. Rod bearings were not as bad as we thought, 2 mains were spun and the crank and block were toast at that point.

On the other hand, spending $6k to get an NSC coated short block assembly (assuming starting with a useable core) is not terrible considering the price of used short blocks these days. And you effectively have a new bottom end.

If mine broke, it would take me a bit to decide between going that route or going kswap. Kswap is a lot more up front but future engines are cheaper. Until those engines start climbing more in price because people are stuffing them in everything. I have seen them in miatas, s2ks ... hell even a porsche!

Have you heard of anyone doing that swap and having a street-legal car (in say California)?

Thanks!

I have no clue in Cali. Likely not out there I assume. They have such over the top rules there that make no sense that I expect it would be tough. I mean IMO, if the car can show good emissions it should not matter what is under the hood but that is not how they operate But I think in most states they do not care a bit about that stuff. Here in MO, unless you live in the St Louis area we just have safety inspections and no smog. We had no inspections at all when I lived in MN, OK or KS either. So you could do it and be fine anywhere that is not looking for that stuff.

I have heard stories that you cannot shut down fast enough after the oil light illuminates, but that is really something. Instant death.

I think the light comes on at 5-10psi, so for sure already doing damage at that point.
