Well, I don't really consider an engine an engine without anything on it. It won't work in a car without all of that stuff.

Is the 500 lb. weight someone mentioned for an ls1 earlier a weight with or with out accesories?

LSHatch · 07-09-2005, 12:58 AM

Not sure. I'll have to check again.

SilverTurboRidin · 07-09-2005, 01:13 AM

a N/A LS1 weighs 480LBS (includes header's, air cleaner,power steering pump, transaxle adapter, flywheel, clutch, and pressure plate.)

PLUS A OLD SCHOOL RX WITH A LS1 SWAP!!!!

And i quote from his cardomain.
"The all alluminum LS1 is actually lighter than the cast iron turbo rotory engine it replaced"

so in reality, all those posters screaming "ROTARIES ARE HEAVY" were just running there mouths? the ls1 seems to be TWICE as heavy.

LSHatch · 07-09-2005, 10:11 AM

For being 300lbs just motor with your basic stuff on it, and for how small it is. A rotary is heavy. And that is going with just a non turbo motor. A TII motor will be much heavier because of the turbo, intercooler, piping, etc. So, there you have it.

I said in the very beginning an LS1 weighs around 500lbs.
Maybe we should all change our facts to one's like yours.

"I've pushed a rotary motor."
"I think they are light."
"I've never driven a 350 RX7."
"I have yet to post any kind of link to support my claims."
"I just make personal attacks to make it seem like I'm right."

Happy??

mazda6guy · 07-09-2005, 12:45 PM

The weight of the motor is not really a major issue because the 330 Horsepower is going to compensate for it. The FB is still goign to be light for the application and i plan on keeping all the interior in the car. The 350 HO motor is going to make my FB fly along with the 3.93 gears in the rear end and the first gear in a 700R4 tranny. PArts are coming in by the boatloads now I just need to stop working so much OT to have time for the swap.

you still refer to it as "300lbs" even though i just told you that its NOT that much. 300 lbs includes things like exhaust piping, starter, ecu, and alternator. as said, the actual motor is under 250lbs. find out the actual weight of the ls1, and what it includes b4 making any more claims please.

LSHatch · 07-09-2005, 01:12 PM

Why don't you read up about 5 posts and Silverturboridin posted what it is. Thanks.

sPrSw2o · 07-09-2005, 02:44 PM

so what we're agreeing on is that the rotary weighs roughly half as much as the ls1?

SilverTurboRidin · 07-09-2005, 03:06 PM

Mazda rotary 2 rotor, 285lbs
Mazda rotary 3 rotor, 480lbs
The weights below are based on motors ready to install into the car. This means the motor has headers, air cleaner, power steering pump, turbo and intercooler (where noted), transaxle adapter, flywheel, clutch, and pressure plate.

Zeropistonz · 07-09-2005, 05:59 PM

Why is everyone arguing?

mazda6guy · 07-09-2005, 06:23 PM

I am am the last to argue. I am saving all that for when I actually doing the swap. Most of the V-8 RX-7 peeps say that it is easy but I know better. Everything dealing with mechanics is a project. I even ordered a new welding outfit just in case I run into a stubborn bolt or nut. I never knew so many people on this board are rotor headz? Amazing!

Jokiesmurf · 09-10-2005, 08:01 PM

Good luck. I'm a rotory fan.Allways wanted a 13b (prerriterial) wrote it in spanish. cause it rev up to 13000 to 14000 rpm's. But also falled on love with this 86 rx-7 with a Grand National engine in it The guy was from Philly The car name was Milady. He used to street race at Delaware ave & Castor ave back in the days.

2001orangess · 09-11-2005, 03:46 PM

i didn't read the whole post, but here's a guy in nj who did the swap and he also road races.

The more i read this me more i realize i don't know shi%. THis is great

Nick13b · 10-07-2005, 07:19 PM

Personally I'd swap a 13B-REW into an FB...Lots of potential for power even in its stock form...and you're still keeping the rotary spirit alive.

which are why rx7's are so cool and unique in the first place.

but a v8 FD looks and sounds mean as hell.

Sid · 10-08-2005, 12:58 AM

Torque!!!!!!!!!!!!!!!!!!!!!!!!!

capaGC8 · 10-11-2005, 08:20 PM

how can anyone argue about this when there's plenty of proof supporting the facts?

just pick up the USCC issue of SCC - there's a hybrid rx7 in the contest this year and it goes into a little detail.

facts:
- LS1 is only slightly heavier than the 3rd gen 13b, most of the additional weight comes from the 6 spd transmission and beefier rear end. (this evens out weight distribution)
- LS1 can be mounted in just about the same spot as the 13b rotary since the SBC has been condensed as it's aged.
- the rx7 has amazing similarity to a c5 vette, but has the ability to shed more weight.

the only problem with this swap is how much fabrication is involved, but it's still the most potent value combo anyone could come up with.

Silverfc88 · 10-11-2005, 08:39 PM

Na, no thanks I'll still stick to my rotary.

Doesn't matter how much people argue. There going to run what they want to run.

I have plans of buying a TII in a couple of months so I still love the almighty Wankel!

Piston powered Rotary powered car, thats not cool dude how can you think of something so disgusting as that. Its rotary keep the rotary love around, who needs a friggin v-8, were a few already, why mess it up with more pistons.

I dont like pistons, rotaries ONLY Baby
