Is it because the VQ is not more reliable than the rotary unit?
Is it because the VQ is not a relatively light weight aluminum block V6?
Is it because the 2nd gen RX7 is not a RWD light weight platform that suffered because of the unreliable motor it came with from the factory?
I guess it could be considered a waste of money when an LS1 bolts right up with a kit and has alot more power / better gas mileage.

Oh look, it's a 13bt, with not an ounce in front of the front subframe.
You miss the point of the triangle, FTL.
Maybe I do miss the point, but the VQ pictured looks like its mounted pretty far back in the engine bay as well. How much does the 13b weigh compared to the VQ30?

its an odd swap but i dont find it a useless one, i think the VQ has more potential then the stock 13b found in those things, and ontop of that has the reliability and actual useable torque when driving, rotaries in general are light but they are not light for their size, a VQs Long block is about 340lbs, throw about 100lbs for accessories and other BS, so like 440lbs or something like that being generous, just browsing the RX7 forums a 13B with all accessories in place is 390lbs, so light wieght is not an big argument, 50lbs is not going to change the world in that car

If that's what the engine bay of my RX7 looked like and someone asked me to pop the hood, I'd feel like the most inadequate man in the world. Maybe I'd install a giant magnifying glass on top so it looks more like an engine than a lawn mower motor...

somehow i would find away to make them all work

If they weren't a complete retard they would know what to expect.

I don't find it useless either, in fact I love engine swaps. I'm just saying you're ignoring the virtues of the triangle. It's not like there is no downside whatsoever to a VQ swap.

The only downside I can see is the raised center of gravity. It appears in the picture that the VQ also sits entirely behind the subframe, and as someone mentioned earlier, there's not a significant difference in weight between the two. The big difference is that the VQ is taller and that means a higher center of gravity. It's not rated at quite as much power, but I'm willing to wager that the VQ-equipped car will pull a stock RX-7 off the line pretty well (assuming both run like new). Power under the curve and whatnot. Also, whatever it loses in handling, it should make up in ability to power out of a corner.
All in all, I think it's a good swap. Depending on what the owner wants to do with the car, the Wenkel setup could provide some advantages, but I think most car enthusiasts (Maxima or otherwise) would agree that the VQ is generally a better engine.
pretty much anything is better than the rotary... but that is not the motor I would of picked... in fact its not the motor I picked.. ohh yeah the ls1 fits most of the way behind the front strut towers as well

none of those. i just think its stupid to put a FWD motor in a RWD car. and i hate switching brands
what about puttin a RWD motor in a FWD car, like what a few people do to the maxima, RB25 swap....just something different, but if imma do that and have the money, i wouldnt use the DE-K, i would use the 350z motor

Soooo... links to this oh so common RB25 FWD swap?

Regardless, there is a packaging disadvantage for the VQ. I never said it was a bad swap, just that the point of a rotary isn't reliability or zero oil consumption. Don't expect it to be a piston engine, because it ain't.

I agree. The stock RX-7 engine is good for its purposes, and it came in the right car for it. However, the VQ offers certain other advantages and is a reasonable swap. Like others have mentioned, however, I think the 350Z engine would have been a better candidate, but it looks like the guy who built it just had the engine sitting around and decided to do something with it instead of rebuilding his 13b again.

Agreed
This guy is truly lost...

none of those. i just think its stupid to put a FWD motor in a RWD car. and i hate switching brands
So what makes the engine FWD? Seems like Nissan has been using this family of engines in both FWD and RWD platforms. How stupid to have such a flexible engine architecture...

that makes no sense honestly, alot of these 240 guys doing SR swaps are pulling the parts out of FWD G20s and NX2000, and RB powered Supras&RX7 and 2jZ powered 240s/RX7 and so on are some pretty stout swaps, have u seen the 2jZ S2000?

Wow for the first time in history I agree with probably the most annoying person I've ever encountered on the internet.

Fair enough, but that's part of the tradeoff for a tiny motor with good power efficiency that's just as smooth at 8 grand as it is at idle.
And Horrible Reliability, Horrible Gas Mileage (Puts v8's to shame) and lets not forget the supposed latest and greatest Rotory seen in the RX8's that was claimed to be 200HP but even with every NA bolt on and mod available could not hit 200 WHP yet it is great at consuming oil and wasting gas with no Trq Gained.
Rotorys are interesting but they just are not my thing. The LSx Swap in FD's etc are where its at and the weight distribution is hardly effected as shown so many times despite claims with no facts that it would cause problems.
Rotorys are fun little toys but for results and reliability no they are not high up on the list.
I am not trying to be mean to you i am just sick of the fanatics. I enjoy anything and frankly to each his own. But frankly some of the Rotory Nuts distaste for anything else gets old and childish.
Some of us want a return on our money of not just Property Value but larger aftermarkets, more community support and larger gains available.

Im not getting what people are saying here about engines, the VG30E that are in 3rd gen GXE were used in Nissan Pathfinders also which arent FWD...
RX7 are beautiful, theres nice ones cruising around here that are pretty fast. Next thing i want to see is a 3rd gen Max with a RB25DETT, preferably mine

Did you even read the conversation? I just went over that they burn oil, if you boost them they eat apex seals and run rich out of fear, and get bad gas mileage. It's all a tradeoff.
I have never owned a rotary car, by the way, so you could hardly call me a fanatic. You could just say that I can appreciate designs for what they are.

According to my RX8 owner buddy...
It depends on what kind of apex seals are in them. If you take an N/A RX8 and boost it then yes you'll have issues like that because with an N/A car you'll have N/A compression ratios. Just like if you turbo an N/A piston car with a high compression ratio/lack of tuning...
There are companies that make racing apex seals for high boost. So that can be solved.
As for FC/FD RX7s that are Turbo/Twin turbo I've never heard of any apex seal problems (lower compression ratio).

PM for cheap Infinity, Rockford Fostgate, and Kenwood car audio equipment!
The newer RX8's are a very nice ride. My mom owns one in Toronto and it seems like a wonderful thing to own. Her's don't burn any oil, but i don't know if RX8's have the same problems as older rx7's.

That guy's name is Darius and the video is older than sin. Still, I'd agree that it's one of my favorite swaps. That's third gear he's roasting just by rolling on the throttle, slams it into fourth and keeps it going.
