Serious Engine Damage...

[Perfectlap]

tough break but it looks like you got your money's worth. Are you planning some while you're in there upgrades?

As far as the mileage and track use, I'll be the dissenting voice and say that Miata engines run this kind of mileage and track time without such consequences and certainly not at such cost.
Not to put down Porsche, just to point out that when it comes to stock engines doing non-stock duty, zee Germans (save for the GT3 stuff) are a long way from the Japanese on durability.

I am sorry to see your engine break up. Be interesting to see the cause and if you do the engine up to the same specs.

Excuse me for answering on your behalf tom .

This is a spec boxster car , so engine must be early 2.5 and all engine internals must remain stock .
(Apart from sump system and ims bearing)
Batch matching/balancing is the only thing allowed afaik ...

Tom, have you considered obtaining BigJake's "CPO" engine?

Replacing the engine instead of rebuilding will likely save you thousands. If I we re rebuilding I'd start at the crank and work my way out. Rings are $1200 so the originals may be fine, but completely clean the pistons so the grooves are clean, rings too.

And don't fare well when installed in cylinders that are .005" out of round...

The rules of this class are ridiculous, the only thing thats legal is building a patched together engine from worn out parts.

The only rule is stock .
How you go about it is your own concern .

It's probably one of the fairest rules in Motorsport .
It means the driver wins , not necessarily the drivers wallet ....

I alluded to the 964 carrera rs engines in my post about batch matching .
It's about all you can do .
It makes for the start of a perfect level playing field

You could probably make one hell of a "stock" engine with all your spare parts jake ....

I know there's no money in it , but it would be good for rep points
