blown engine

I didn't read all 10 pages of the thread but I decided to replace my blown 3.6 with a boxster 3.2.
I will be posting a summary and feedback on new thread after my upcoming first weekend breaking it in.
Qualification:
This is for a dedicated Race Car but am sure this could easily be done for street car (even in CA) and easily pass smog.

I've read that to pass smog, you must replace your engine with a donor engine from the same or a newer model year. Did you find that to be true?

I think the only way the engine swap would become a Smog issue on a road car is if you were instructed to get it inspected by the Referee . That may happen if you got tagged as a "Gross Polluter". When the Referee reads the engine number, it could betray a non-permitted engine swap.
The question is how would they read the engine number? If you keep all the under-body shields and covers on ,they would not be able to see the number without dismantling and removing parts.Are they allowed to do that -or can they require you bring it in for Testing with engine numbers exposed ?
Eventually their computer may be smart enough to 'see' changes to the DME. But I doubt such technology would go back over a decade?
So I guess the trick for a road car with a discreet M96-to-M96 engine swap is to make sure you always pass Smog Tests by a safe margin and keep all the covers on ?

We swapped a lot of the parts from the 3.6 but the block was toast.
I haven't posted much in recent years but if I can figure out how to put the pics up I will share of the 3.6 and then of the 3.2l.
As mentioned I will be with Vali from ValiMotorsports this weekend and we will be shaking out the car. I am excited and nervous at the same time.
The 3.6 was a beast in those Glorious 4+ laps. I never talk about "how fast" I go because it's more about lap times and cornering speed but 157mph was nothing I have ever experienced before and probably won't again with this 3.2l

On the smog...from my experience (probably 30+ smogs)
I have never seen a tech check an engine block...my feeling is that numbers marching doesn't apply and we took the Dme back to stock. Car will never be a street car though as I have custom exhaust with no cats

I mention the engine number issue because others may be tempted to try swaps on a street car. Simple Smog Test is easy.Hence my encouragement to always get a pre-test and always make sure you pass with a generous margin. Once you are tagged ,your car is always under suspicion -particularly if your car has a profile of failure or tampering.
When you have to go to the Referee it is a totally different level. You & your car are basically guilty until they decide you are innocent . The Referee seems to be a law unto themselves.

I've heard on several occasions - but never understood - old-time racers say that their cars often felt amazing ("best power ever") right before they popped.

Unfortunately, many performance cars and other cars that are "often modified" are getting tagged for inspection at "STAR" stations. Some folks have said that their STAR inspection wasn't any more detailed than any other smog check, but both times I've gone, the tech has spent a decent amount of time crawling around under the car with an inspection mirror and flashlight.
The days of me sneaking through inspection with long-tube headers and spark plug extenders on the Corvette appear to be over.

Updates: quite a bit of leak/grime on the IMSB. Will see better with the flywheel removed hoe the RMS looks. Looks like the leak has been going on for a while based on the layer of grime around the vicinity. This should have set the alarm long before the failure...
The bearing does look like an LN unit. The clutch, pressure plate, and the flywheel are all in great shape. The flywheel springs in both directions smoothly and returns to the center strongly. It has some wire brush marks on it maybe from the tech cleaning it up. There's very little clutch dust inside the transmission housing. Looks like Cringly was very easy on the clutch
