For about 1/3rd the price an LS9 and can live with just 525hp

Would be a cool and reasonably inexpensive setup to put a hopped up LQ9 into an old beater 928 that had a scrapped engine. I would never however do a GM engine swap on a good condition 928.
What I would love to do is to be able to find a totaled Panamera turbo and swap about every single salvageable component into a '87+ 928. Modified to fit of course. Driveline, interior, suspension/brakes, electronic niceties, etc.... Now THAT would be cool, as well as keeping it all Porsche.

Great to hear from you, Chris!
The V-8 from the Pana is too tall to fit under a 928 hood. The Pana needed to meet some pedestrian safety standards so the bumper and therefore the hood line are several inches higher than those on the 928. Otherewise I'm sure this conversion would have already happened somewhere.

Too tall?, why that's why they made welders. Fabricate some new components to drop it down. Then put a power bulge hood on it. LOL. Shame though, as that would've been a cool swap.
Tony, yeah I think that's a bit more of a beater than I was thinking. LOL. That something you picked up, or just saw somewhere?

It takes a particular owner to appreciate the southern flag-draped "power Bulge" hood on the 928. You'd still work hard to find space for the intake air compressors and such.

Welder won't solve that darn ground-is-too-high problem, unfortunately. Even with 3" training wheels on the oil pan, no go.

I am wrestling with my next steps regarding engine. I currently have 136,000mi on the clock and plan on needing in the next 2 years the following:
1) Top End refresh(hoses, ISV, CPS, other sensors) and powder coat($1000)
2) Timing belt and water pump($450)
3) Generator($200)
4) AC compressor($350)
5) Starter($300)
So roughly $2500 assuming I don't break something while in there.
A brand new Chevrolet LS3/430HP Crate Engine - $5895.95 with free shipping.
LS Controller Kit is another $1,100. Renegadehybrids.com has the LS conversion kit for $2000.
So a completely new setup with +100 extra hardware, guaranteed for 3 years/100,000mi for for roughly $9,000. Not doing the repairs mentioned above means only an incremental $6500. Not pocket change but I get the sense a rebuilt 928 engine is going to be +$12,000. I figure I could part out my original engine or sell it outright for $2500-$3000.
This would eliminate my current circus of random idle fluctuations despite passing all diagnostics(is it ISV, LH, EZH, grounding, etc.). I would sleep better because I would no longer have to wonder if my current problem is a TBF as is evilly suggested on the forum. Or also wondering if the occasional waft of gas smell in the cabin is a fuel line bursting turning the car into a mobile molotov bomb.
I want to stay pure but dropping in an LS saves money and greatly increases reliability.

So, if I were to swap it would be Chevy's manual transmission that I'd go for. Not because I prefer the Chevy manual to Porsche's 5-speed, but because Porsche 5-speed's are hard to come by. Since I have an automatic, there's no way a switch to a manual could be considered stock. Might as well go with plentiful, dependable, and relatively cheap.
