My engine is toast

Thanks, I've read that long 987 vs 986 airbox thread a few times. I'm only doing this because the engine is out! And other than sourcing the 987 S airbox, trimming off the muffler and plastic welding the hole on the back, I'm not doing it! My shop will install it while the engine is out. They've done this a few times. I'm not sure if they're going to use the 987 MAF holder/tube thing with the screen or somehow use the one from my 986 airbox. I was still surprised by its size when the box arrived yesterday, and continue to be impressed by what members of this forum contribute!

Much better airflow if you retain the 987 MAF tube but then you have to program the DME with the 996 tune or a custom tune.

I dropped the airbox off at the shop today, they're going to let me know about changing the tune to use the 987 MAF tube or using my old MAF tube.

Turns out my LN Single Row Pro IMSB failed. It was in the car for about 36,000 miles. I still have the original IMSB, which had not failed, although engine oil continues to leak out of the intact bearing seals into the ziplock bag it sits in. My timing chain rail on the back of the engine also broke, who knows which went first. The heads, block, crank, rods, pistons and cylinders are all good, but the engine needs a new IMS, some oil pump parts and timing chain rails and tensioners in addition to rings, bearings, gaskets, etc. I guess all the time I've spent here taught me to shut the engine down as soon as I heard an ugly noise.

I'm thinking about the 3.6 LN Nickies and pistons, but they think that will add at least 8 weeks to the job, in addition to the cost. Once I see the estimate I'll probably come back to reality and pass on this upgrade.

Looking forward to hearing about the price of the rebuild.

My 01S, which has a failing, but not yet failed, timing chain, was seeing numbers north of $5K just for replacing the rails alone. It's all about the labor cost.

BTW: my guess is the rail failed failed first and destroyed the IMSB in the process.
