Does anybody have a 2nd gen w/ a 20b (J-spec Cosmo three rotor, rotary engine)?
Anybody made the swap?

 

Its been done. There are a few on the forum that have. Patman has.

 

The little search dude is hilarious...I did search but found mixed results and wanted some more opinions! Thanks

 

Yes.

Yes.

Why beat a dead horse. Ted gives info when it is warranted.

Otherwise, noobs be warned.

[sarcasm]3 rotor swaps are so 1995, go for the 4 rotor. Its just as easy. [/sarcasm]

 

if you havent the time to search, why ask.

a 20b swap will take you so much time you gf will leave you, expecially if you are unable 2 make up your mind about it.

you sir have way 2 much time on your hands, to ask a question to which you already know the answer.

the force is weak in this one obi wan

 

also have done it

 

doing it right now

The car is for sale.

 

I have a bit a sympathy for blkturboII. I have noticed and just observed today that if I put in "20b" in the search engine, I get Sorry - no matches. Please try some different terms.
Granted we all know our way around the forum but a newbie might try to search and figure that it is something that is almost unheard of around here. You still could of looked harder. Can someone tell me why 20b returns no matches? I thought it was something that was part of the general problems of the website. I figured it would be fixed by now.


And yes, doing it now, or preparing anyway. Finished by spring hopefully. The swap can almost be called foolish. Do you know how nice of a car I can go buy with the money I am going to spend on an engine and install. My FC is going to end up being a $40k car that I might be able to get $18k if I am very lucky. 20b is great for internet dreaming but really makes no financial sense at all. That being said there is no other engine install I would think of pursuing. To add more absurdity to the mix I am doing a non turbo. So all this money for 350rwhp. I could go buy an RE and turbo and make way more horsepower for way less money buy it wouldn't be a 20b would it. Good luck, you have been warned, if the disease bites you are you are going to wish you never heard of the 20b.

 

The search engine will not search for anything 3 letters long or less.

 

Well there you go....Thanks, I figured it was something simple.

 

i didnt originally do mine but since i bought the project i have taken it apart and pretty much redone it. i have rewired the complete engine and ECU, taken then engine and tranny out and everything that goes into it........but i dont want to give my self any credit because i did not make any of the pipes that you HAVE to do to make the swap happen. with the rite mounts and a good ECU the swap in really easy, its the costum work and money getting the parst you need that make the project a scarry thought. if you have the money then just do it like NIKE. but then again if you had the money this would not be an issue cause you could pretty much put anything you want into ANYTHING you want. the FC is the best for the swap cause you dont need any craddle or anything, i bolts rite in (with the rite mounts) and its old enough to were you can tear into the car without feeling to bad............anyway let me shut up before i start getting haggled by TED agin LOL !!!! man that dude is mean.....

 

i have some pretty good pics of my car and its engine bay. i'll send you a PM......

AGAIN!!!! before i start getting attacked by you true rotary pros out there, yes i bought the car with it done, but i have since taken it apart and put it back together on my own just to see what the fuss was about.

conclusion: if you have an FC it will drop rite in, other than that it all comes down to costum pipes and parts good enough to keep the engine happy.

 

Say, "quixotic". That's sounds ever so much better.

Don't tell him THAT. That's supposed to learned the hard way.

 

Not true. There are many modifications required that you obviously missed when you reviewed somebody else's work.

Amen.

 

ummmm.......this is what i saw that was costum.
-intake pipe
-exhaust manifold/downpipe
-fuel rails
-all the lines were braided stainless steal
-fittings
???? off the top of my head that whats stood out. i was actually suprised to see that there wasnt much to it.......now i my in fact be wrong since i only have a few years with hands on experience with this and dont claim to be an expert in no way shape or form, so if theres tons more to list please do tell cause i would like to know what i missed. and yes this topic has been covered but it seems that everyone has taken a slightly different approach to this but the end results were all good. one thing though is that my car is completely stripped for racing. there is no A/C, no heating, no anything that dosnt need to be used to get it running and on the road. so i guess if you want to keep all those luxurys then yes you would have to move stuff around and make space for the extra pumps and compressors ect ect. yes i guess you can say im a noob but werent we all at some point.

 

if you want an accurate search you have to change the settings on the thread display date from default to show all threads. The problem is that most relevant threads are pretty old and most of the veterans have changed their settings already & U have not changed yours. Go to user CP at the top of the screen.

Most of the above is actually optional.

What you missed was:
-replaced water pump (the stock dual thermostat housing would stick out of the hood like a periscope)
-custom motor mounts (Stock Luce coupe mount can be used for one side)
-gutted TurboII hood, relocated steering rack, or lowered intake manifold (stock 20B misses being wedged between the stock steering rack and the stock TII hood by about 1")
-modified front sway bar or oil pan (stock 20B oil pan hits the stock FC sway bar)
-aftermarket lightened flywheel (stock 20B-REW only came with an auto transmission and no flywheel)
-pulley set and belts

Of course you also have a completely new EMS and ignition system, upgraded cooling system, and other items that are required to make the engine work once it is installed in the car. The oil metering pump also needs to be addressed. I probably forgot some things too.

Anyway, you can quite plainly see that this is NOT an easy drop-in conversion.

 

but...

water pump is easy and virtually free because a TII one will work
motor mounts are now available several places fairly cheap
fixing the hood takes 10 minutes with a cutoff wheel
i offered the swaybar relocation kit for sale for a while, no one was interested...
flywheels are easily available on ebay- 200 bucks
stock TII pulleys work fine.

i dunno why you guys are so elitist about this. Can a guy with no mechanical skills do it? Hell no. But its really a fairly simple swap compared to a lot people do since you can buy mounts, the driveline bolts up, and the engine fits in the bay.

 

Swap right in?
Sure...
$100 - $200 worth of engine adapters, and it drops right in...

Having it crank, fire, idle, and drive is a whole nother ballgame.

I'm really tired of getting questions like: "Can you tell me exactly how I put a 20B into my (non-turbo) FC?"
I stopped answering questions like that a long time ago.

Look at the Hawaii guy that's selling the front clip...

Dun...dun...dun...another one bites the dust...

Sometimes it's not suppose to make financial since. You can't just put a price on everything (cost vs hp). Some of us do this swap because we are just plain rotary enthusiast or have a specific goal in mind. It all depends on what you want.

 

yup...but i'm not stopping because of difficulty or money. something really great happened for me, and i am simply no longer interested in the 20B or my car.
sucks for me but great for the person who buys the clip from me!!

 

EXACTLY!!! It's a dream to own one. Most people don't get it. Spending $15k on the swap when half of that money spent on a 13b could be twice as fast. I spent the dough not to have a fast car or to go out racing it every weekend, more just so I have the best of the rotaries. What I have always dreamed of owning. A 3 rotor FC. The sound of the engine different, the looks of the intake manifold intimatating, and the feel of the additional torque pleasing to the back.

Could I have spent the money better elsewhere... sure! So could have the guy who spent $1million on a McClaren. I don't think he is complaining either.

 

Not sure what you two are doing wrong, i type in 20b or 20b swap and i get tons of post. Most of them irrelevent, Yes, i have found plenty of good info. This is how i came to find out about the subframe that you can buy now., since i am about to venture down this highway.

To the OP, Search...it's not hard....you might like it.
