Convince me not to LS swap my FD /o/
>>
Do it if you want more power, better reliability, ironically lighter setup

Don't do it if you want to retain the cool/unique factor of having a rotary
>>
do it. put the 13b in your lawnmower
>>
M8 don't do it you will drown in pussy, literally you will drown in a sea of vagina if you do this.
>>
You'd be losing the uniqueness and character of the car.

Put the money into rebuilding the ruggedizing the dorito imo.

LS swap it! Those swaps are sick. but you would lose the privilege of saying you have a dorito powering your car.

So you spend 20,000 dollars to go from the 300 stock to 420 or whatever a crate LS has these days when you could just up the boost and improve the cooling systems.

It's one thing if American burgerbarges blubber like burgerbarges, but making foreign cars blubber like burgerbarges is just an awful thing to do. The exhaust note alone would ruin the car.

That's not how it works

The fastest FD in the world is 13B powered. You can also build a reliable and more powerful 13B for less than what a non-half assed LS swap costs.

rotary's are cool but I don't understand why their better due to only being different. (not just copying what matt farah stated). They use a ton of gas for not a lot of performance and have a very high maintenance level. I would only touch one if i knew how to fix it all myself otherwise it could cost you a lot to maintain.

>FDs must be ls swapped
I know it's a common thing, but really just buy a 'vette if you want cheap v8 power. No need to ruin a classic sports car.

It's probably cheaper than buying an FD and then swapping it, too.

Furthermore, the RX-7 is designed around its rotary engine, putting something else in there will fuck up the 50-50 weight distribution and super low center of gravity.
>>
>>14254693
2jz swap it instead :^)
>>
alternatively put your 13b out of rx into a miata. nothing snaps necks like a nasty rotor idle out of something unexpected
>>
>>14254762
>I would only touch one if i knew how to fix it all myself otherwise it could cost you a lot to maintain.

which is convenient because rotaries are dead fucking simple. I could take one apart, and do a full fucking rebuild and port job with the right tools, and I sure as fuck would need help with a piston engine. Rotaries have no crank case with crazy counter balance, no rod bearings, no camshafts no timing belt and valve wizardry.

It's literally drive shaft, rotor, apex seals, spark plugs, rotor housing and exhaust/intake ports.

sickening

Fuck it, not going to LS swap it. Here is the plan.


Engine Rebuild + Street port
New JDM transmission
New or Rebuild stock twins
Remove emission related vac hoses
Install Vmount
Install Boost/temp gauge

I think all this labor wise will run me around 3500 here in SoCal. I already have the vmount and the gauges.

Anything else I should immediately do that i'm forgetting?
>>
>>14254693
Do you live in America? Buy a Corvette. It will be cheaper and it's basically the same thing. Conserve the rotary.
>>
>>14254786
I don't know a lot about FDs but I hear single turbo conversions are popular.

Now we're talking. I'd suggest upgrading your intercooler, and radiator, and installing an oil cooler and catch can if you're looking to make serious power in the future. They can remain stock if you want stock power. Obviously you'll need a boost controller, bigger injectors and and obnoxiously large exhaust if you want to achieve lots more power too.

Make sure you get that EOP delete and 2-stroke oil premix too.

http://www.rx7club.com/3rd-generation-specific-1993-2002-16/save-whales-save-your-motor-887275/

Rotaries ARE fucking reliable if they have proper cooling and lubrication, and upgrading cooling systems and deleting the EOP + 2-strke premix takes care of that perfectly.
>>
>>14254797
They are the way to go, EFR is what is hot right now, but it's very expensive. For the time being I can't afford both the stuff above and a single swap.
>>
>>14254802
My vmount comes with a really thick intercooler, not sure of the dimensions, also comes with a koyo nflow. Since i'll be running stock ECU and twins i'll probably only be pushing around 280? Maybe close to 300 if i'm lucky.

The boost controller though I will probably need, you're right, my boost will probably be creeping.

As performance engines, rotaries do have a lot of advantages over piston engines.
>better power to weight ratio
>can rev to the moon with minimal damage or wear (basically indestructible as long as it doesn't overheat)
>fast, hot exhaust is great for turbos
>small form factor, great for mounting in FMR configuration for good handling

The main downsides are:
>susceptible to flooding when cold
>get carbon deposits if you don't rev them high pretty frequently
>guzzle gas
>need to be rebuilt more often than most modern piston engines, even if the rebuild is really simple
>drives terrible with an automatic (high rev power + lacking torque)

which when combined make them somewhat impractical for daily driver appliance cars.
>>
>>14254693
Do it, rotary is good, LS is gooder
>>
>>14254822
you forgot some other downsides
the apex seals have to travel much further than a set of piston rings
eats oil
it still has reciprocating mass
>>
First, go drive a C5 Z06.

Do you like that?

Because that's EXACTLY what an LS RX7 drives like.

Ahahaha how cute, Americans thinking their lazy torque barges actually being the same as Japanese sports cars.

Actually, I think that they are within 100lbs of each other with the swap. The C5Z was only about 3100lbs

The parts for a LS swap alone are $4500, and that's not including the engine and transmission.
>>
>>14254924
See>>14254963

Just proves youve never swapped anything than the cum out of your boyfriends mouth

Single turbo and cooling mods will be cheaper in the end, can increase reliability but your petrol consumption will still be shit.

The only reason I would go LS is if I'm driving it everyday

My FD was fairly trouble free, after I had it sorted
>>
>>14255174
Considering that many FDs are still running around with the original engine untouched, 20 years later... Yeah it will take a century to cover the costs of an LS swap.

Not saying its that terrible but you're a fool to think the two turbos aren't hugely disadvantaged
You have much more to worry about, more heat, etc

A rotary itself is reliable. Adding forced induction is the problem. Bro had an fc n/a, most reliable thing ever

You mean camry you dolt, he doesn't want to cut the springs and put 60 lb wheels on it
>>
>>14254802
Leave the oil pump in there. Sohn adapters are better for street run cars. You'll spend time off throttle at high RPM with no lubrication going to the engine otherwise.

Also, the 2 things that kill FD's are a tendancy to lean-spike if the exhaust is changed without re-turning the ECU, and all the heat soak from a solid cast-iron exhaust manifold.

Replace or recitify those and it'll be happy.

Might as well sell the FD and buy another car.
If it doesn't have a rotary it might as well be another car

>>14254963

So you are automatically forced to buy somebody's kit in a seller's market instead of weld and fabricate your own?
>>
>>14256230

You think I'm gonna pay somebody 4 grand for some mounts and brackets when I have a welder?

For the cost, time, and effort, I'd just buy a c5 or c6. The rotary is part of what makes the RX7 the RX7.
