Re: holy ---- the sky is falling, Jd wants a K series.
There's several V8 swap guys that did what you're saying. Braced the differential and built follower arms coming off the hub that went forward to the frame rails. Pretty much killed wheel hop. They still blew the stock diff though. Or a CV joint. The ford 7.5" diff is cheap and much stronger. Plus parts for it are reasonable. ---- for a mazda 7 is crazy high. For the cost of a torsen swap and new R&P you can buy the 7.5" kit.

There's a 175 lb weight range among LSx flavors. Which were you thinking of that's so much heavier than the cast iron Miata mill? You know LS1 weigh 325, and L33 less.

Pat, I think you overestimate the intelligence, experience, and knowledge of a handful of random engine swap guys. You'd have to link me to videos of the cars launching, or "hitting it" from a roll, so I can see how the rear end tracks.
I'll have to pay the prices I mentioned for L33, the engines being somewhat new and me not having any domestic or junkyard hookups.
Frank, a friend of yours in Oki also had a ~450-ish Miata, and that's (Zeroyon) is one of the places I found a theory that goes counter to the popular meme that Miata rearends are junk.

I'm around 270whp now and it's sick.
Needs a LSD bad though.

Re: holy ---- the sky is falling, Jd wants a K series.
Maybe, maybe not. We put more power to the ground out of stock Honduh econobox transmissions.
Follow my logical order of what the pop culture "knows" about a D-series gearbox: D-series are weak --> D-series differentials are weak --> D-series differentials are strong, but not all of the diff pins holding the spider gears are correctly hardened, so they fail. Refinements such as D-series gears are stronger than B-series due to how compact the gears themselves are eventually filter in. There are a lot more 350+ whp D-series out there than 200 whp Miata so this logical progression in popular knowledge only took 12-14 years to come about.
:/
I don't want to hear "the diff is weak" or "the rods are weak," I want to sift the wreckage with my own two hands and form an intelligent conclusion. For example, fools hammer rod bearing upper halves into the crank journal with detonation until the bearing welds itself to the crank, the unit locks up, and the rod breaks. Fools say the rods are weak and are listened to "because they've done it." I say the rod is possibly quite strong and the fools need to find another hobby - a perfect example of this is reading Honduh forum posts of a decade ago where "6 psi D-series" and "8 psi B-series" is the most you can safely run on a stock Honda engine - barely at or over 200 whp with the turbos and manifolds used at the time.... now the intelligent consensus is that D-series rods will hold 300+ and B-series 400+.
So, after laying this all on you, Pat... what do you think? Did Honda do it right and no other automaker has a clue, or is the popular consensus largely useless? I love me some Hondas... but there's a lot of excellent ---- out there that doesn't have an H or an A badge on it.

Re: holy ---- the sky is falling, Jd wants a K series.
Thats almost the exact speech i give to people all the time. As honda people, we really are ahead of the learning curve over alot of the other "groups of car people" out there.
Also a tranny/rear end will hold a v8 with the exact same tq better than a 4cylwith identical tq because because the v8 has smoother force, ie every 90degrees a cylinder fires compared to every 180degrees for a 4 cylinder.
