My stock engine was severely worn by the NSX modified single turbo kit I had on it for 2 years\20000 miles. The kit never worked right, it had no intercooler, it had negligible timing retardation(?), crappy air\fuel, and an unknown number of jackasses 'test-driving' it for the 4 to 6 months that larry garcia of nsx modified had posession of it for the "install\tune".
Essentially the death of the motor was a 1-2 punch. The NSX mortified 'system' washed the rings, cooked the inside of the engine with ultra-hot intake temps, and undoubtedly detonation caused metal fatigue in the stock pistons.
By the time good ol' GJ put on a well designed system with good A\F, timing, intercooler, aquamist, the 340 RWHP it put down also had the effect of breaking loose the already cracking ring lands on the stock motor.
For the record, it blew up the day after I had done a 1-2-3-4 gear almost redline run, she ran like a top with no detonation or any problems, but that was the first time since I had gotten the car back FROM NSX MODIFIED that I had (almost) redlined it. I was always scared to go much over 5500 - 6000 with the garcia pile on top of the engine. So its quite possible that even with no GJ on there it would have blown the ringland simply THE NEXT TIME I REDLINED IT.
As for rebuild, that 3.2 isn't rebuilt. Its in GJ's shop, I may sell to an interested buyer as-is.
My new 3.0 thats in the car with full GJ everything and then some was around $13K installed with 10 hours of cleaning added in free (had to be there).
The car now runs like a top, I have just around 2000 miles on the new engine with the second oil change of non-detergent kendall (GJ's break-in oil for chrome ring motors). In another 600 miles, I will drive up to modesto(add 400 miles) to change the oil to regular (kendall 10W-40 GT1) and a dyno tuning (the car can be ran to redline on the dyno after the 3000 mile break-in)
We changed to cable throttle, it made a huge difference. A couple of times I have slightly overboosted to aroun 13 or 14 PSI, pretty f@ckin snappy and thats with a baseline TEC3 program with conservative everything.
So anyway its been a long expensive journey but I'm glad the path led to GJ, if it didn't I am sure I would still be slow and miserable. However I do have a feeling there are some up-and-comers in the FI big dog arena, I have a feeling Mo is about to make a nice piece.
