How bad would it affect the handling of our cars if they had been 2jz swapped?

 

GTFO boinger ***.

But seriously, it'll throw the weight dist off, making it a front heavy car. Thats bad.

 

it just depends on how far you mount the motor back, i have a friend with a ls1 fc and his is still close to 50/50

 

I thought 2J's were iron bottoms? Whereas LSx's are alum?

 

I figured it would. Me and a friend were debating it and I just wanted to get some other opinions.

 

Check the weight of the two engines. And throwing off the weight distribution doesn't mean the car will be undrivable...lol. It means if you're setting up the car for time attack or HPDE it'll have more tendency to understeer and be less predictable. 90% of the people on this board probably wouldn't even notice the difference in handling...so if you're building it for roll/highway or drag racing then go for it.

 

this.

 

Complicated answer: Depending on how you rearrange things under the hood, you could easily get the car to a 50/50 static weight distribution if desired. However, the longer engine will most likely increase the polar moment of inertia, which would reduce the handling capability based on how much the inertia is changed.

Easy answer:
No offense, but anybody asking this type of question on the internet has absolutely no clue about handling anyway, so I don't see much point in worrying about it. You may as well debate which engine would better allow the car to withstand a direct hit from a meteorite.

 

Just go buy a supra

 

Why would you say that?

Asking how much a far heavier, taller, and longer engine would affect the handling in a lightweight well balanced car seems a pretty reasonable question to me, especially somewhere where people should be able to give him first hand experience

 

+10000000000!

 

Weird that you are already assuming that such a swap must have an adverse effect.

Maybe, maybe not.

First of all, I think it's a mistake to assume that the majority of RX's- still equipped with the rotary engine- are properly "set up" to begin with.
Got non-stock shocks, lowering springs, aftermarket wheels and tires?
What kind of "set up" adjustments did you make to optimise the handling after they were installed?
Furthermore, what are you setting up for- driving to work or lapping Roebling Road?

Too many variables and too broad a question.

I've worked on/driven a couple of V-8 swapped RX's and, on the street at least, they handle fine and are a friggin blast to drive.

 

What's a 2jz? Is that one of those machines with the round things that go up and down?

 

I'm not planning on doing this swap. Just wondering of a general idea. I figured it would make a difference and my friend didn't think it would. Just a trying to get an idea.

 

if you put it in the hatch it might not be too bad

 

I thought that Toyota truck from the commercial was meteorite proof?

 

Key points:
Long story short:

You would first need to understand how the rx-7 with the rotary handles at its 100% (which is impossible since the biggest variable is the driver) and then swap it, which at that point you have completely changed the physics of the car, i.e. how its power is put out going into and through the corners. At that point, you can't even really compare the two. As stated earlier, the biggest variable is the driver.

 

I say that because even I know how to use the equation WxA=M, and I am an idiot.

So you think that the original poster is a highly-experienced professional automotive engineer who is asking this question on this forum so he can get some help setting up his team's race car?

Yes, they did make that claim in their commercial, but unfortunately there is some disclaimer text at the bottom of the screen.
