Maybe drop one of these in the oilpan.
Good for water boats, gotta be good for land boats.
Should be, enough.

D, You forgot to add back in the sold GTS motor. I would have paid as much or even more if I found a GTS with a new LS376/480 powerplant, and I think some might have done the same, not all, but some. That $ 30,000 for 928 Stroker was according to the conversation I had with the owner just 2 weeks ago at the 3rd Coast event. I don't want to divulge his name because that's his business. The estimated maintenace costs on a new LS376/480 motor (without routine oil changes) looks to be about zero for the first 100,000 miles. What would that be for 2 - 3 timing belt changes and adjustments? Then there is always that fear factor of the t-belt letting go, it does happen. Don't forget about the most important issue of all and that the "Fun Factor" of 500 hp at the bottom of your right foot. Whats that worth? L, Nothing to do with my ad bus. Motor Oil, only Mobil 1 Syn 15-50 in all of our vehicles. T

Neighbors '09 Z06 spun a couple of rod bearings the other day. That was kinda fun to watch. Same **** different car. You shouldn't be anymore worried about a TB break than spinning bearings.

At least it will be under factory warranty 36 month, 100,000 miles if that pretty rare occurnce were to happen to a Chevy crate motor. Really, when was the last time anyone heard of a small block chevy grenading that was not under full race conditons? (re: 1/8th, and 1/4mile drag racing) Don't forget to factor in that there are there are an abundance of small blocks out there doing there thang! T

Not all out racing, just daily drivers as they drove there.
VERY VERY few LS6 engines have I ever mopped up, only since the LS7 came out.
..since you asked.

Broken timing belts are not as common as you might think, especially when the cars are maintained.
I wouldn't know, but could you be creating or exposing other potentially expensive reliability time bombs by dropping in the vette motor? In that case, your trading the known (timing belts must be changed) for the unknown. I guess the engine is far and away the most expensive and hard to find GTS specific part though.
There aren't many 928 transplants out there, even less in the hands of the original owners, so we don't often hear about the long term reliability of these efforts. There are usually a few 928s with transplanted motors available for dirt cheap though which says something.

If people could reliably convert to a LSx motor for $12k, we would see it happening on dozens of cars every year. Some cars do get converted that cheap, shops make foolish estimates, people get lucky buying a Chevy donor car, but the range of cost and end result pretty much START at $12k and go MUCH MUCH higher depending on how the dice roll for that particular conversion. Maybe half or more die a quiet death unfinished in some garage, others are finished enough to use on the track, but not as daily drivers for the usual hot rod project issues. $25k is a much safer estimate providing you have a shop with experience in doing a 928 conversion.

GM Performance 19211710 - GM Performance 2006 Corvette Z06 LS7 Engine Assemblies $15,029.95
GTS is going to lose around $10k in market price with a good clean swap, and most buyers won't even consider it.

Nothing to do with being a purist or hot rodder but just a little out loud thinking on the subject, the Z06 engine produces 505hp from 7011cc, the GTS 350hp from 5.4 litres. The additional 155hp is pulling 625lb less so your power to weight ratio is significantly in favour of the Corvette, conversely the perceived benefits when required to pull the additional weight of a 928 may not be as great in reality. Also that additonal weight will have a knock on effect regarding fuel consumption so you may not get as big a saving there as thought..
Setting aside the paranoia concerning the TB, which the fitment of a Gates belt should help ease, then 505hp out of the GTS engine with the fitting of either T/C or S/C should be easily achieveable at far less cost than a transplant.
Now being completely sad, and irrespective of whether or not this thread is seen as an advertising ploy, there are two reasons why I'd consider going for this transplant. First it's great that you've got a wife that share's an interest in cars, mine couldn't care less what colour it is let alone what's in it or powering it. Secondly and more important to me, and here's where the really sad part comes in, you can't beat the sound of a big block yank V8, assuming you can fabricate an exhaust system that does it justice.
The last may be a mute point though if you crank that stereo up!

I've got to say, I don't see the point of using a GTS as the donor:
1)You are going to wreck the value of the only 928 that has become a true collectible, probably losing $25K in lost value alone.
2)The GTS is the heaviest and most complex 928 made, which will complicate the process of the install, and provide less bang/$ compared to earlier models.
3)The cost of replacing the timing belt, or actually repairing a catastrophic belt failure, is chickenfeed compared to a SBC swap.
If you are really set on doing this, pick an OB or US-spec model pre-85. The total cost(motor + install + car) might be less than the install plus lost value on the GTS. You'll get better performance, for less money overall.

There are quite a few extras that are gonna be needed to run that engine in a 928, actually in ANY other car other than a C6 Z06. It's a dry sump engine. It needs an oil supply, and last I checked, unless you start cutting up more of the car, you aren't gonna fit what is necessary under the hood of a 928. That's just ONE problem you WILL encounter.
Food for thought!
