Everything you list if fine to do with the exception of the LN developed IMS bearing. That is one of the items that Jake has submitted for approval. It should be accepted imho.
All of that and more is also in BRAG's build kit you asked about earlier.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

It wasn't Spec Boxster specific Paul, just seems I read that they had figured out how to rebuild the stock M96 motor for better longevity, which i'm sure (since they aren't sealed) wouldn't violate any SB rules.
Edit: a quick look at the LN site shows a couple things. Replacing the IMS bearing with their bearing and carrier seems like a smart idea along with running a 160F thermostat. With a 3rd (center) radiator the car should run cool in even the hottest ambient temps. What are the other weaknesses? I would run the sport oil seperator, deep sump baffled oil pan, and underdrive pulley. Also seems an oil pump gear is an issue, not sure how much of one though..

The IMS isn't a performance gain, but is a reliability gain so I would think it would be embraced! Brad's kit is quite comprehensive and if I build a car it would be the way I go.
What are the "normal" failures? Is it IMS? Blown head gaskets from running too hot? Just curious..

most of nor cal BSR motors are over 100k miles. only one went bad.
cost 3500 to find one, why bother rebuilding?
that's like the cost of two set of hoosier for my GT3. if the motor can last one season, i am happy. and mine did.

The least expensive route is to buy a crate motor and accusump. Other than that you are gambling. I tried to go the used motor route and they didn't last. I ended up installing a crate motor and then selling the car. They are a blast to drive but the motor issues can bite you.

My biggest problem is that the motors are known time bombs, regardless of how many or few miles are on them. I hear guys talk about how cheap they are, but I do not see any $5000 cars or $3500 motors out there. I think that I might wait to see how this season pans out, but I see it costing around $30K to build a front running car (with a lot of personal labor) and then it could average out to a motor a year.
I would feel a lot better if we could build one right, and then not have to worry about it for a few hundred hours. That's where tha aircooled motors in the stock classes have a big advantage.

I guess we’ll just have to agree to disagree that just because once upon a time Porsche remanufactured an engine that went into someone’s street car that ultimately came out with 30 K miles and went into the Spec Boxster you sold me that it’s no longer a crate engine. Maybe it’s just me, but to me, when someone advertises “Brand New Crate Engine” in a For Sale ad and during pre sales conversations the seller says “it has zero miles on it” and it’s a “Remanufactured engine from Porsche” then the buyer finds out it has thirty thousand miles on it after he bought it…it’s not really a crate engine anymore.
…it was probably just my misunderstanding of the whole transaction; clearly my fault for living in Virginia and buying a race car in Texas that I didn’t inspect personally.

A. A reman from Porsche, not new as stated
B. Was run in a road car for 30,000 miles
C. Was put in a Spec Boxster (or was the road car converted?)
D. Was sold as a new crate engine with 0 miles on it.

I always thought that a crate motor is a new motor, you get them from a parts catalog, but a reman'd engine has miles on parts of it. That's how it worked way back in my FoMoCo days.
More to the topic:
Larry, you're singing the 944SuperCup theme more than you know it. I ran upfront all year last year and have just as much car left for this year, I'm in it for well under 20K and never had so much racing. Just move the engine up front and add water.

A remanufactured engine from Porsche was installed in the car before it was sold. It was later discovered that this engine had 30K street miles on it. In an effort to make John feel better about the deal, once this was discovered, I purchased a set of wheels and tires for him.
