IMS failure - Which new engine?

Not all IMS failures are a complete write-off -- but at a minimum
will require a complete tear down and rebuild.
Unfortunately you can't tell if the engine is rebuildable until
you put the time in to tear it down, inspect it, and check to make
sure the block is not damaged in any way. There are a few telling
points that limit how much you have to tear into it that will give
you a negative rebuild answer.
YMMV, but there are a few options out there.

03 Boxster-S IMS blown
Hi There,
I just barely bought a 2003 Boxter-S with under 12k miles on it I drove it 200 miles after having it fully inspected and the IMS bearing failed leading to massive engine failure. I am staring down the barrel of a very expensive engine rebuild through Porsche and I am interested in learning more about these alternative options.
What did it take to get the 3.8L in there?

It is possible that they could be but the expense and ongoing trouble if this is not done right would detract greatly from your enjoyment of the car.
Your best bet is to replace the failing engine with a new factory engine either through a dealer or through an indy shop.
While these are both expensive the new engine drops right in and afterwards you can't tell the engine's been replaced though you don't want to hide this fact should you go to sell the car.
If you want to you can get an otherwise identical engine from a Porsche salvage business and have it installed. Risky cause you don't know the condition of the replacement engine. But many have gone this route with success. Others have not been so lucky.
A variation of the above is you can buy an engine from a similar MY 996 and with some bit of extra work this can be made to fit and fit rather well. More than a few shops around the country have done this before and the results are very good.
But you start getting into real issues fitting a different design engine even though its hardpoints are the same as the original engine into a car.
But do your research. The suggestion to visit:
flat6innovations.com & lnengineering.com
is good one.
I've never visited these sites looking for any info on fitting a 3.8l engine into an older Boxster so it may not be the big scary job I think it is.
Take your time. There's a lot at stake and you want to have all the facts before you make up your mind.
Sincerely,
Macster.
