Not according to the article.
It looks like Retter supplied the A2W IC and maybe the water jacketed turbine housings from what I gather.
Maybe he will chime in with what he knows about it.
"Retter, RED, Precision, Retter Engine Development, Popeyes, hookers, buttsecks".......tags for when he googles himself, so Ryan will see this. lol

After reading the following article I became sold on the LS platform.
Wondering why people are still screwing around with big blocks and superchargers in boats when a turbo LS will do the job with more reliability .

The fact of the matter is, we don't really know if the BIG hp LS stuff will truly live in a boat. Jimkid has proved that NA LS stuff (LS7) works really well in his skater. However, I have never seen data that says that the big inch big hp turbo LS stuff can live in a boat...but if it does, it certainly won't be a stock bottom end setup like HotRod had on the dyno. It's hard for me to say, since I'm one of the biggest turbo LS fanboys there is. I think for the article to claim that a 1500-2000 hp LS is more reliable than a BBC of similar power is a bit far fetched, and certainly premature.

Weisman has a real clean AVS with twin LSX N/A motors in it. Cool video about LS building by Tom Nelson of Nelson Race Engines.

Ugh...please, please, please don't quote that Big Bang HotRod rag article. So many people read that and automatically assume that stock LS junk can make 1000+ reliably, then build one and scatter it at 650 rwhp. I have built and blown up enough stock bottom end turbo LS stuff to know for fact that is not the case. lol.

So what's the problem?

Totally agree. I have had a bunch of buddies that have blown up stock bottom end LS motors with turbos that were no where near 1000hp. That's why I built the **** out of my bottom end just to be able to handle 600hp N/A in a boat.

If Merc was starting from scratch with the QC4V, why did they chose to go straight to 9 liters, instead of something smaller and throw more boost at it?
Though when I swapped the LS into my jet boat, I did like to run that thing balls out down the river...but it was only at 400 hp, and only turning around 5000-5500 rpm.

My weight saving was a lot more significant than that, but I also weighed dressed engine vs. dressed engine. My stock 310hp 454 was 1060lbs with iron intake, iron exhaust, iron heads and all the accessories. My dressed 408 LS2 is 560lbs. That's a 500lb savings over the 454, which is pretty substantial. I also decided to try the aluminum blocked LS2, which saves 100lbs over the 6.0 iron truck block. I know the iron is a little stronger, but at my power levels, the aluminum should still be just fine. If I ever go boosted, it'll get swapped out to iron. I will also concede that a lot of the weight I saved, could have also been shaved off a big block by switching to headers and an aluminum intake. My goal was to build a motor that was roughly equivalent to a hp500 in power and weighed a lot less.. I'm pretty sure fully dressed, I am still 250-350lbs lighter than a fully dressed hp500, and am making slightly more power. But my main reason for doing the swap, was simply to be different!!

As I was reading your response, I kept thinking "yeah, your boat anchor ALL iron 454 is was heavy....and configured much differently than a "max" effort BBC".....then you covered that point. lol. good work.
I don't have the weight for an LS2 shortblock, but my buddy did weigh an LS1 at the same time, and it was actually 130 lbs lighter than an iron 6.0....figured you would get a kick out of that info, since there's lots of different numbers floating around the net, which is exactly why he weighed them all.
Thanks for the weight numbers on your swap. Certainly very interesting. I wish I had a heavy duty enough fish scale to compare the 454 from my jet boat with the LS that went back in.
