Brand spanking new engine! Yes!

do you know if the engine included some of the changes to the 2.5 or is the exact same design? I'm wondering if Porsche recognizes a problem with a design from many years ago do they modify the designs in stock or just send out the same thing.
The 2.5 had some issues with regards to porosity. Doubt you'll notice it unless you put on major miles.

My mechanic tells me that the new 2.5L engines Porsche supplies now (from 99 on) had crank shaft changes (now they're not out of round which caused the RMS failures). I am not sure if they corrected the porosity issues. Mine only has 15k on it and appears to be running very well.

BTW - When my mechanic put the PST2 tool on my Boxster last night before he replaced the O2 sensor, the MAF sensor appeared to be underperforming and he said "you'll need a MAF sensor before long." After he replaced the failing O2 sensor (post cat, 4-6 cylinder position) the MAF began to work flawlessly. Apparently, one affects the other in a performance way and it's hard to pinpoint which is going out with high clarity.

All I know is that the engine idles steady now, runs far more quiet on the freeway at 70 mph and it feels like far more than an O2 sensor was replaced. Combine this with the new clutch, transmission and brakes and I'm on cloud nine. I feel like this last 2500 bucks really put the car in top operating condition. Wish it was warn and dry enough to drive it again tonight!

I bet I'll see better fuel economy and a boost in power now. If it's dry Saturday morning I'll drive out beyond the horrid Houston traffic and open it up and report back here to you all.

Very informative post. I'll give you the opposite side of the exact same car. That way potential buyers can see both sides of it.

I bought a 1997 Box for $24k about 2 months ago.
36k
All service records, indicating that the only work done on the car ever was the 15k service and 30k service, with spark plugs at the 30k service (which are usually not part of it). All services done by the dealer.
new Continental tires and 45k service done (early) by my dealer prior to purchase
2 year factory warranty.

About a month after having it, I realized that the belt was making some noise, so I took it to a different dealer than the one I bought it from, where they replaced the belt and all pulleys for FREE (covered under warranty).

Anything that goes wrong in the next 2 years is covered, and my dealer is really nice about this stuff so far.

Bottom line: I bought the same car as you, paid a lot more, and will be guaranteed no issues for the next 2 years. Plus, it came with new tires!

So I guess the question is whether my level of insurance is worth the huge premium I paid over your car. In my opinion, it is. But that's up to the buyer to decide.

yes I went through the same with my Miata. Everything that needed replacing was chucked and upgraded (lighter clutch, flywheel,headers,exhaust, adjustable suspension and shock mounts, proper spring rated coils,shift boot, all fluids etc.
I spent $3-4K. But what a transformation. Sold the car a year later for 2.5 times the blue book and more than I paid for it.
