Some say its impossible.
I say nothing is impossible.

 

Lol...

 

pufff, should had put a v8 on that thing

 

ya but I like horse power, fuel econ and reliability, lol.

 

you get all that on an ls-x

 

Without a rotary, its not an RX-7..

and in what way is this a build thread? Should be posted in the other conversions section

 

lsx is a sweet engine but it also comes with a corvette sound that I didnt want to hear coming from my rx7, I still wanted it to sound like an import and I am willing to bet the lsx costs more than a 2j. I am also willing to bet the 2j is just as capable as the lsx, with a single turbo upgrade and a fuel system you can make some pretty big numbers on stock rotating assembly.

 

The Wankel is the soul of an Rx7. Remove it and it loses it's uniqueness.

But that's just my opinion. I have to give you props for your hard work on the swap. That was good work.

 

thank you for the props, I dont hate rotary's and at the time I couldnt find my dream car an mkiv supra, so I decided to build my own, lol. I would love to do a 20b swap on one these cars some time just too see what there like.

 

I figured it fit here cause its a 2nd gen and it was a build.

 

I was planning on doing a 2jz swap in my fc...

Tech2 mounts --$1750
2jz motor----$2000 +
2jz bell housing --$350
1jz tranny---$1000 +/-

pretty straight forward swap too....I may have found a deal on a 20B tho so........ we will see

 

Build threads are meant to show the entire proces, this is just a vid of the result.
But still, ANY non-rotary RX-7 should be in the other conversions section, it is there for a reason..

With the title you mislead people that love the rotary and think that there might be tips for making it reliable, instead we find another RX-7 that had a pigheart transplant..

Dont get me wrong, Props on the build.. if you did it all yourself and not just spend cash?

 

Wasn't intending to mislead, rotary's are reliable if you leave them stock, from my experience. Pig heart is what I would call an sbc transplant, instead I chose the heart of a dragon, I agree the heart of a dragon will weigh more than a heart of a house cat lol, its a fact muscle weighs more than fat.

I am not offended by your comments in any way infact they made me laugh so please dont be offended at mine.

and yes I did do the swap my self and thank you for your props.

I will say if I was going to auto cross one of these cars the engine of choice would be an ls series engine, they make great power in a small compact light weight package.

 

I've never lifted an lsx engine, however I can lift a 13b by myself (not very far, but I can pick it up) and I only weigh ~150lbs. So, there definitely isn't much "fat" on a rotary engine block haha

 

the 13b is too heavy to be a boat anchor its not no 150lbs, when I took mine out it was heavier than I expected, the guy that bought it from me wanted to load it in a trailer, we thought we would just pick it up and put it in, well forget that, lol.
ended up using the engine crane, the only engine I have been able to pic up on my own are honda engines and 4g63t engines and thats hard enough to not want to do it unless absolutely necessary.

I kinda think its funny that the engine weight thing came up cause I was just looking at that yesterday and the tab on my computer was still open.

I did research power train weights when I did the conversion I was well aware that ls series engine was the lightest swap you can do to the car improving its handling characteristics. but I wasnt going to auto cross the car either and I did not want to do what so many others had done plus there is no denying that the 2j is an awesome engine even if it is "a heavy pig".

^ LOL, and yes, I am sick of all these motor swaps, but if you want reliable..............

 

The rotarys can be reliable also, just depends on the tuner!
And also the RX7 won't be faster on the racing track with heavy V8s or 2JZs! Those are just for strip racing

 

This is not even remotely true.
Ask largeorangefont what he thinks about roadracing a V-8 swapped FC.

Most casual swaps ("casual" in this case means not specifically aimed at racing) end up very close to original weight and more importantly, weight distribution.
The swapped FD I was involved with was exactly the same weight as stock and had 49.5/50.5 weight balance and that was with an iron block. An alloy block LSx would have been even better.
Furthermore, the racing V-8 would be NA and no NA rotary will approach the power and torque level easily achieved with the piston engine.

If you want to talk about race cars, you must also talk about money.
I can order up a 500hp V-8 crate engine that is 50 state smog legal for $15k...show me a NA rotary that can do that.

You can talk about the soul of the FC all you want and I can't argue.
I don't agree but it's the kind of emotional decision that can't be refuted.
When it comes to hard numbers though, your statement is demonstrably false.

 

Point is you don't need all that power to be competitive. The FD is using a 13B PP NA (obviously, but some won't know).

 

Well, think about how 'competitive' that Corvette would have been against the FD if the FD had the same engine as the Corvette. Just a thought.

 

.....have any of you ACTUALLY driven a LSX swapped rx7? Much of this threads false accusations would be gone. If you have never driven a properly swapped rx7 you cant comment, simple as that.

 

....have any of you ACTUALLY driven a 20B swapped rx7? Much of this threads false accusations would be gone. If you have never driver a properly swapped rx7 you cant comment, simple as that.

 

well, think about how 'competitive' that Corvette would have been against the FD of the FD had a four rotor engine. Just a thought.
