hmmm


Still sweet tho :thumbup:

[jchxcrx]

Yeah... but that LS1 weights a whole lot more than the rotary

I wonder how bad it will mess up the car's balance, it would be a
shame to have an rx7 that handled like crap, you know?

Either a shame, or a sin... I'm not sure which...

[NismoR34VspecII]

Whoa, dats insane, LS1.Weird but i would of swap an 2jz or RB26dett motor in the 7...... :thumbup:




[COLOR=orange]Chew on this, Trident!!!!!!

[95TSiEVO6GSR]

Im all about the supra motor in one...but still that ls1 is damn fast....

[3rdgenRX7]

there is some guy on rx7club that putting in a ls1 in his 7. 600rwhp N/A or something like that. Razorback knows more then i do bout it. Its going to be insanly fast but he has spent 100k on it probobly. Wont be as good for road courses but straight line......DAMN

A*fully dressed 2000 LS1 Corvette engine ready to install with the engine computer and wire harness, complete exhaust system, engine mounting brackets, AC compressor, alternator, custom water pump adapter, transmission adapter plate and flywheel weighed 434 lbs.

ref - http://www.toy-jet.ls1fun.com/about.html

----------------

The complete motor, with accesories, top to bottom complete ready to fire in the car is around 300 lbs TOPS.

I carried my longblock in the house from the back of the truck,so id say its 250 lbs for al longblock.

Tranny weighs about 120 lbs with converter.


So about 400-450 lbs complete with tranny

-------------------

One of the main engineering goals of the RX-7 was to stay close to the perfect 50/50 chassis balance. When they added the extra weight of a turbo system to the Turbo II model(180-200lbs), they needed to come up with a way to maintain the chassis weight balance as much as possible. Some of the methods they used include...

...They went to an Aluminum hood
...They moved the intercooler rearward to the top of the engine
...They used a heavier spare tire & jack

ref - http://members.tripod.com/~grannys/rx7balancing.html

While finding this I did run across documentation about how to try and maintain the 50/50 balance after performing an LS1 swap in an rx7.
So apparently it's possible.

1. Yes, a complete LS1 does weigh more than a 13B rotary [which i'm assuming it had].
2. My statement was speculation... however it is obvious how much care
was put into designing the rx7 in relation to it's handling and weight balance.
Some monkey bolting in an LS1 is less likely to take the same care with the
vehicle's dynamics than that... not to say that it wasn't done in this particular
swap, or in others, or some guy you know etc... just to say that it is less likely.

[If this is inaccurate then I apologize in advance... I just did a quick search to
compare the two ideas. Not to try to slam anyone, but so far I don't see
anything wrong with what I posted above. I am still concerned that the handling
balance is not going to be right after installing a motor in a car that was clearly not
designed to house it.]

[I8ayellowcrayon]

no it doesnt.

no it doesnt.

you have no idea what your talking about..

The RX7 was built to be a great handling car, and by putting the tiny rotary engine in, it gives the car better balance (weight ratio). Have you ever even seen the size of a 13B?? Its smaller than a Honda engine, and a Honda engine weighs about 250lbs. An LS1 engine weighs a lot more than that. If you could just imagine, an LS1 has nearly twice the parts and size or a Honda engine... The next time you see a 7, ask to see the engine. you might think twice about saying that my boy doesn't know what he's talking about :thumbup:.

ok now lets compare the weight of a 7 with a TURBO..

oh yes dont forget the option of Aluminum heads or hell even an aluminun motor. wanna start guessing weight now?

now lets do some quoting..



"mine weighs 2700lbs and has perfect 50/50 weight distrobution. *shrug*"

his mods.

93' R1 "57b"
LS1, TR224 cam, 918 Springs, Ti Retainers, Comp Pushrods, JBA Shorties, NX 150 shot
11.7 @ 128.77 mph"

holy shit..someone is mistaken;) now what was that about not knowing what i was talking about?

he has an ALL aluminum ls1 corvette block with aluminum heads i believe a t56 tranny alot of custom parts (ie motor mounts, etc.) the engine was dynod in the area of 640 hp all motor. he has probably spent 100k on it easily. and in the area of 20k on the motor alone. it is not something you wanna fuck with.

[jchxcrx]

Do you have anger management issues?
Did I insult your manhood by doubting that an LS1 in an rx7 would handle right?

Aww...

This started as a friendly observation...

Learn some manners.

e-thug

nope just cant tolerate people who have no idea what they are talking about.. and you have the misfortune of being one of those people:)

[Triepsyn]

Alright. That's great. Calm it down before someone blows a gasket. :thumbup:

As merkur says..
come on guys, this is getting so old......cant we all just hold hands and sing kumbiah?

Seriously guys. :D

[3rdgenRX7]

i think the comment about "next time you see a 7....." is what sparked the comments by razorback

[I8ayellowcrayon]

Based on the information I got out of this thread, the motor was a basically stock LS1, which weighs a lot more than a rotary engine.

he has an ALL aluminum ls1 corvette block with aluminum heads

Added after my post.

My comment about "the next time you see a 7" was completely out of context, I had no idea that Razorback had a 7, so you have no reason to go off on me. All the same, I may be wrong, but I really don't care. Like everyone on Honda-Tech says, "Arguing on the internet is like the Special Olympics... Even if you win, you're still retarded".

nope just cant tolerate people who have no idea what they are talking about.. and you have the misfortune of being one of those people:)

Dude, let it go. I personally also think its pointless to put an LS1 in a 7, so I'm obviously not going to like the idea. Based on our knowledge of the engine/car, we just don't think it would be the best thing to do.

[Mr. Merk]

AND THAT'S ALL SHE WROTE. <there is a period there :thumbup:


kumbiah my friend, kumbiah..... :welcome:

[3rdgenRX7]

lol........ I dont think razorback was going off on people more of being a smartass which every1 is every once in a while. I dont think that lil bit should upset people that much.

[Triepsyn]

Hey guys, guess what..

<center> period, big fricken period. </center>

:lol:

[razorback]

i can tell some people have problems accepting the fact that they are wrong;)

no even without an entire block being made out of aluminum the difference between the two is very slight. if any.

[Mr. Merk]

kumbi-fricken-YA!

[3rdgenRX7]

friends argue all the time over stupid stuff why is it so wrong to do it on the internet. I mean I was wrong too I thought the ls1 would mess up the 50/50 more then it actually does. razorback has reasearched i was wrong and so were other people.

[Triepsyn]

Discussing ideas, numbers, etc. That's all fine

.. But name calling is childish, benign, and demeaning.. I'm not about that. So it won't go down.

But yeah, discussing is cool. DISCUSS AWAY!

Otherwise practice the Merkur-Method, Kumbiah. :thumbup:

[Mr. Merk]

shut up caleb....jk :thumbup:

no really, we got that, we all understand now, some people may have different opinions but oh well its resolved now, hence the "that's all she wrote, period"

but he keeps talking......

no offense, i just hate it when people keep talking after the other debaters have left the building, i'm stickin my nose in everyones business cuz i'm sitting at home with a bum leg and have nothing else to do, my apologies

[jchxcrx]

I don't have a problem with being wrong.
When I first posted in this topic I stated what I felt to be probable truth.
If I was wrong... whatever. That's fine. I'm mistaken all of the time...
It's part of being human.

I never presented my self as the end-all fountain of knowledge on the
subject, nor did I go around telling other people that they were ignorant.

I'm down for a debate... they are entertaining and informative.
If he had simply offered an explanation for his side of the story then
this would still be a happy topic.

Are you just trying to make everyone angry?
Or is this the only way you know how to communicate?

Honestly... I'm stumped

[juggalo]

well this is interesting and every one is wanting to hold hands and hug....CANT WE ALL JUST GET ALONG? :lol:

[razorback]

damn..didnt know there were so many sensitive people on here;)

[Mr. Merk]

yeah....i think its cuz we have curly hair..... ^_^

that and i'm on drugs, i'm like adam sandler in that movie where he gets rich, u can stab his foot and he cant feel it, yah, hardcore pain killers right here! wooo! :)

Not so much sensitive as trying to be concientious of others on the board. It's the whole respect factor. Like I was saying, discuss & talk shop... But name calling is rude and childish. You can still have a good time without attacking someone's character. If you're kidding, thats one thing. But you could definitely feel some sort of tension rising earlier.

Just as long as you guys respect each other, regardless of if you agree with what they are saying, then everything will be fine. :)

[I8ayellowcrayon]

First of all, I don't know Razorback... That right there makes things a lot worse than if I were debating with Patrick or someone. I really don't care if I'm wrong either, I've been wrong MANY times before, even about my own car. But when I think that I'm right I'm very persistant, especially when someone is being a smartass about it. So here it is guys...

I'm sorry. I'm wrong. I am a complete idiot and have no earthly idea what the hell I'm talking about (at least with 7's :)). This will be my last post in this thread.

Not being a smartass - have a nice day!
