Why do people do wild swaps(RB, LS1), when u can just buy a Porsche, Ferrari, etc?

Fully dressed weight of the LS3 with all accessories on it (as configured in a C6 vette) is around 450 lbs. and not much bigger a package than an I4, just wider, which is why it can be swapped into virtually anything.

This pic is very misleading. The engine on the left has full accessories/alternator/thermo/pulleys/etc bolted on, full intake manifold fuel delivery and tb, valve covers, etc., etc. Take all that off and it'll look like an Ethiopian child next to that V8, maybe 2-3x smaller, lol.

The one on the right is basically a naked engine. No valve covers, no intake manifold fuel delivery tb's, no acc/alt/thermo/belts/pulleys, it's also missing the very lower portion of the block oilpan case and the crankshaft cradle/girdle (once you add all that, that's at least another .5' of engine height).

I'm thinkin a stroked twin turbo'd Busa engine. Could you imagine the looks you'd get when you bumped the limiter on that at a meet?
LMAO!!

So, despite money spent on GT86’s tuning on literally weekly basis, it effectively saves me from buying new, much more expensive "amusement" cars – like methadone therapy instead of heroine

Yes, I enjoy tuning too. Especially a car like this. And great points.

I guess I'm just saying that I am kinda against disrupting the weight balance and cog of this car by plopping a big motor in it. Also kinda against ruining the great handling/suspension engineering behind it.

Now, if it was a different car, especially like a classic car with old engineering that handles like crp anyways and is nowhere as good as a modern car (like a 240z, a 510, etc), then I am totally all for it. But ruining a modern and very well designed chassis is kinda funny to me. (kinda like plopping a V8 in a porsche lol)

Good observation, and I figured most knowledgeable of engines could look at just the engines themselves. Yes, the I4 will look skinny as heck next to the v8, but the height is, like you said, only .5" to 1.0" once the LS is in full trim (especially since in ours cars, you would be using a custom shallow pan/dry sump system). I agree with what you said. If it fits in a low hood-line car like ours... it has no problem fitting in almost anything that has the width necessary for the V.

So for info, I will post with more trim. No A/C, but hey, screw A/C.

Have you rode on a properly set up swapped frs? How do you it will magically make the car handle like crap? You talked about constant reliability issues...what about any modified car? Seen the thread of the boosted frs on here where the owner said they were in the shop every week or two to fix something else? Taking a perfect running motor, putting it a different car...will still be a perfect running stock motor. With the same power as a modified fa20, that WILL have issues.

Then changed the settings on Forza from rookie to novice.

That pic seems to give evidence to those your using it to disprove. That almost naked LS1 with no accessories, no valve covers, no intake manifold or anything is already almost as big as that fully dressed Mazda motor.

Now for sure many people assume a V8 swap is going to weigh much more, when typically the difference is not so much..at least considering the engine itself..not sure how those swaps always end up after transmission, sub frame stuff, rear end, etc

I will be doing something like this to a 1989 Mazda rx7 hopefully. The one and only vanity plate I have ever liked was on an rx7 and it said "Rotorless".

It makes the car unique and it can be a challenge which requires true skill (and loads of engineering and math) to make a functional car. Next level Shiz compared to buying and bolting on parts.

I said foot, not inches ...and that's in comparison to that standard tall i4 in the pic.

Now, compare that to our short, flat, boxer 4.. even worse of a difference in height.

After swapping in that LSx... there goes the Twin's wonderfully super low COG out the door

I did specifically say, if it has the width for the V right? My main point being the overall height/weight of the engine stays relatively the same in a lot of cases, which will not kill the balance of a car. Of course the LS is a bigger package, but its mostly different in width, not height, so you're not killing the COG/balance on most cars. Maybe a little on ours since its a flat-4. Sorry if I didn't word it correctly. The valve covers and intake manifold aren't exactly huge (and the intake is plastic, so its a light piece too).

Sorry, I will stop de-railing this thread now. lol

yup, I agree with you on the twins, it loses it's super low COG. But then i heard one with the swap, and I fall back in love with it lol

No I haven't.

Maybe it won't make it handle like super crap... but it won't have the same nice low COG anymore and you'll need to do months of study, research, development, testing and tuning of all suspension parts to make everything handle good after having new weights and positioning of the new engine.

Yes I agree, that is true of any modified car, original engine or not. But, a swapped stock motor won't necessarily be trouble free. Maybe it will be very reliable internally...but, there will still be probable issues down the road/build with mounts or design, positioning and fitment, chassis mods, drivetrain, engine harness and electrical, ecu, etc., etc.
