I thought rotaries would be really complicated but they look pretty easy compared to a piston engine
I think piston engines look more simpler when they're cut in half. Rotaries do seem more transparent though
Here is the rule for repairing cars, it always looks easier than it is.... (this is from the little personal experience that I have)
@@Imshittingmypants No truer words have been spoke lol. I always watch engine swap or tear down videos and think "thats easy" then when I try I end up thumbing it home 😂. The people in videos are always just perfect. Nothing goes wrong. All the best tools. It almost never goes according to plan irl. My dad always says "if its got tits or tires it'll give you trouble sooner or later" lol.
Piston blocks are easy build.. it’s the heads that are a head do’er
@@stgeorge5862 Good planning makes a good engine build.
from a Mazda tech, thank you for building these so I don't have to
three wheela lol
I was the first person to build a Mazda rotary engine on the East Coast back in 1979. No one was building them and the factory wanted all the engines back for research and develvopement. The engine back then was a 12A Dual Distributor with points ignition and 4 b carburetor. I wish I had a rotary to play with today.
@@ncautoman57 Cool story! You should buy a rotary for fun. Have a good 2019 sir.
Bet u lose a lot of money
@@ncautoman57 what is your age
In order to yield those bolts correctly you have to put a little oil on the head of the bolt where it makes contact to the surface. Especially with bolts that long because you will bind the heads of the bolts against the surface before you stretch the bolts.
I've always been in love with rotary engines and every day i'm doing more research. I really wanna rebuild and port my own when I get my rx7 but the more I learn the more sketched out I get
They are a labor of love and just like all performance engines, they require a lot of TLC to go the distance. BUT I wouldn't let your research sketch you out, if you do your part and take your time when you do the rebuild and the porting (I really suggest having a competent machine shop do the porting though, probably with a bridgeport) that will give you a solid base to work from. You heard them mention premixing in the video, that will really help the apex and pate faces last by cutting down on wear like the gouging and chatter marks you saw on Dave's original, so will spirited driving (because in FD's that oil injection pump works off throttle position, a stab of the throttle injects a slight bit more oil into the chambers). These are good engines and with the right maintenance and diving them like you mean it, they last! If your going to run it as a dedicated race car and trailer it, you can see ware like Dave's example from sustained high 7-8000+RPM (all the track time and tuning issues) but for normal gear heads going to the track for test & tunes and stoplight races/highway pulls, these rotary engines hold up exceptionally well NA or turboed. Sorry for writing a novel I just felt like you needed some heartfelt reassurance to pursue a worthwhile interest, maybe even a dream. GET IT DONE!! Good luck bro
Damn, i didn't expect anyone to even notice my comment. But this is really reassuring, and i'm very glad that you took the time out of your life to coach a young grasshopper myself. I hope to find a nice FC to dump all my money into within the next year or so. Patience is key when looking for these beautiful cars, and your kind words really helped me hang in there. Thank you very much man!!
Np brother! I have a bit of experience with the 13b both turbo and non, and for gear heads, theres nothing better, I mean come on they respond to spirited driving by increasing their service life! Once you find a nice example man, you won't be disappointed. Just take your time with the rebuild, get a factory service manual and make sure everything makes spec, and you'll have a seriously fun car/engine combo and be one lucky dude, cuz you'll own a running driving FC! Good luck man, and really I'd rather have the car than the money anyway! Haha
Few people can tolerate the low reliability, short service life and high operating costs... its also why people stopped buying the new ones too.
So cool! I WILL have a Rotary car at one point in my life
Rotary ae86????
Wow. What a goal.
Awesome! I really appreciate these kind of tech videos. Thanks for all the hard work guys. Need moar...
so when he said "16 thou" im sure he meant .0016 which is read 1 thou 6 tenths if anyone is confused and the "35 thou" is to be read at .0035 which is read 3 thou and 5 tenths because 35 thou is read to be .035 and 16 thou is read to be .016 which is a lot of play. this is just for anyone who was wondering or is confused!
These are so relaxing to watch damn specially after a joint =)
These engines are very interesting. I like the fact there’s less moving parts in them looking at one in the video I’m willing to bet there very light engines. I wouldn’t mind putting a turbo charged rotary in a fiero or Mazda Miata or mr2.
yay Thanks for the 1 day late birthday gift :DDD
Nog van harte!
7MPower
bedankt :)
Big fan of all piston ported engines, had more fun and didn't get run over.
Seen some rotary motors that aren't a wankel., I think it's a company called Liquid Piston, not 100% sure, but it sounds right.
You could use crows foot to get a torque wrench in them!
Was that rotating assembly dynamically balanced?
I think I need to get another Mazda my last Mazda was a 87 turbo 2 blew the apex seals miss that car
did you mean .0016-.0033 for end play? that would be 16-33 ten thousandths
I was thinking the same thing,sounds like his numbers were too big
You sure aren't scared to slice those fingers on that sharp edging, are you?
Excellent
All you need are some crows foot wrenches for your torque wrench and you can torque the oil pump bolts to spec lol
Do you have any clips of the RX8?
Yup! ua-cam.com/video/P6MzYDPA7NU/v-deo.html
Sounds amazing! Braaaaap
Saw a vid yesterday with some dudes building giant versions of a 4 rotor making like 3000hp for marine purposes. They make any hp you want, the cash varies with buggery required to build them obviously. They were only like 2/3 the weight of comparable diesel. That version also ran on diesel! They were like 3 or 4 hundred thou to buy from memory. Install and ancillary components make it an absolute wank. Anyone with half a brain would just get a mtu 2000 or similar, last forever.
Link?
What happened to Joe's finger? Looks gnarly
got caught in a belt on a piece of farm equipment when he was a kid.
Count how many times he says ugh haha
New drinking game?
I was looking for someone to say that it was driving me insane lol think before you talk!
"How good are you with rotary engines?"
"I fabricated my own lobe socket when I was 14."
"You're hired."
now my urge to get a rotary is increasing.
Do it, you won't regret it. But get an FD. Not an RX-8.
+gav240z I love the rx8, but I'm actually thinking about getting a NA fc. The reason why is due to it being a good base point to learn about them.
LanEvo55 whichever car is cheapest to obtain and cheap for parts. So earlier ones might be a good start.
just buy a 2 stroke weed wacker. same sound, same torque and much cheaper.
+Simon Liu not really mine is stock been that way for 6 years no problems at all.
Best 38 minutes I've spent on UA-cam in YEARS!
jort88 I actually watched the entire clip without skipping. the first time ive ever done it. heaps of knowlede acquired. Thanks!
Great
Ditto, zero skips enjoyed watching it come together and learnt a couple of little things too.
38 min went by flying but really learn something new today
How much is all of this worth?
I see Vaseline on the table. Aaron Cake would approve. "Like most enjoyable things in life, it takes about a half a tube of lube to get the job done right."
lol. ironically I just watched his videos the other day
its nice to see someone else watch Aaron cake! :)
Aaron and Joe actually know each other quite well. The rotary community in Southern Ontario is pretty small.

The real doktorbimmer no one wants to be part of your club bro.
FUCKING YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES
that engine is actually beautifully simple.... possibly more so than a conventional engine
+zephy1001 *The Wankel's lack of sophistication and flexibility is also why it is obsolete today.*
"obselete" lmao you mean innefecient yet fucking awesome?
let me remind you of all of the V8s in America...
lol, i still see snowmobiles, rc cars/airplanes and the like using them. hell mazda never stopped making them, they were still using them in theyre formula mazda carts last time i checked
Obsolete doesn't mean it isn't novel. It means there is no practical reason to select the engine (e.g. typewriters are obsolete). The only reason to choose a rotary is because they are cool. Darcy's comment on American V8s is a foolish one when you look at the remarkable efficiency of the LS series V8s.
Of course we have a dip fuck in here who likes the LS motor and talks shit about the rotary motor and yet probably still knows nothing about them probably a import hater to thinks American muscle is god
Torque with a crowsfoot wrench with a regular torque wrench attached.....works for Boeing, will work for you.
exactly what I was thinking, snap-on do sell then in 1/4, 3/8 to suit your tension wrench and 1/2 inch drive
Actually called torque adapters
Works for the Air Force!
Crows feet are a good option, you can also get torque wrenches that have a u-bolt to attach a spanner rather than a square drive to put a socket on. They are good for getting into difficult spots. The one I used to use had a two position telescopic pointer which you used to set the length of the spanner and there were two scales to set the torque, one for each length. that seems to be old technology now, all the new ones use a spanner quick connect attachment which comes as part of the kit.
As a little girl I was fascinated by a transparent plastic Wankel rotary engine that my brother had assembled. It had a little light that was where the spark plugs would be to show the ignition cycle. I think I had more fun with that thing than the boys did. Then again, I am the one who became an engineer, they are bankers and cops.
As a little kid I was complaining about how literally everything is based on exploding a stupid piston up and down when the source of power spins and the goal is to get something else to spin. A rotary engine is just the most obvious design. Pistons that just slam and vent are the stupidest thing I could imagine only 2nd to the fact that people still BUY light bulbs that you have to TWIST into the socket not just once, but like it's a bolt holding a bowling ball preparing for an earthquake when you can make LED light bulbs plug them in like an audio jack using Cork like the original design and never buy lightbulbs again unless it's a gimmick bulb for a studio set or something.
@@linkeddevicesThe Wankel is a clever bit of engineering but unfortunately it was an epic failure, it's simply inferior to reciprocating engines... too unreliable, dirty and inefficient to compete with the earlier concept that we still use.
I was racing rx3s in Japan in 1982 and we took off the exhaust and made our own header,hollowed the intake manifold,made a template for a Holley four barrel,added mad ignition and away we go! That was the fastest car in Okinawa as I could rev to over 12,000 rpm and only a guy in a 280 z with it bored to a 3.2 l and triple dell orto carbs but he still got smoked! Good times late at night in the marines! I was a mechanic at the rebuild shop so after 1630 we worked on our stuff until midnight and that’s when the racing guys start gathering at the A&W to race!
We did a lot of work on the ports too,enlargening them and experimenting with the opening for a longer intake duration and a lot of polishing!
Do you have pictures of those builds?
You guys should do a video about how to own/care for a rotary properly so that it is as reliable as possible.
Good idea!!
patrick valentine drive 20 minutes low rpm so oil and water is at operating temp and then you can go race it my dad has an rx7 for 15 years and never had to change anything to the engine just maintain it good
Step 1: This is critical... Don't modify the engine! So many idiots rape the shit out of them expecting reliability from an 80 cubic inch engine. Mazda didn't design these things to run 500 plus horsepower, so don't come to YT crying about rotaries if you hack the shit out of them.
1. Add oil. Often. Like every other tank of gas often. If you really wanna be vigilant, premix.
2. Let it warm up before driving as often as you can. at least 5-10 minutes if possible.
3. Redline it at least once every time you drive it to clear out carbon deposits.
4. An annual seafoam treatment never hurts
5. Don't flood it.
6. If you can afford to, upgrade your spark/ignition system (starter, coils, wires, etc), the LS2 kit is a popular choice.
@@taborgilzinger8522 Nice list, but the seafoam stuff scares me, probably because I don't have experience with it. I've owned my FD since it was brand new with 9 miles on it. I'd add to your list to take a slow in-lap after a spirited drive. I like to let the turbos spool down on my way back to my garage. My house is about 2 miles from the entrance to our subdivision so it gives me plenty of time to go 25 mph or less on the way in. If it's really hot, sometimes I'll trick the fans to keep running longer by leaving the A/C button on with the ignition in the on position for about 5-10 seconds before getting out of the car. Dunno why, but that makes the fan run longer when you walk away.
this makes me almost confident that i could rebuild a rotary myself if i get all the parts ... holy shit.
I’m currently watching this because is time for gasket kit to be done thanks
brap brap brap brap brap brap brap brap brap
well that was a lot of Vaseline - so no chafing issues there!
brap brap brap from a good hard wankel
Rotaries are like two strokes, simple and small, but high power! But they are both hard to take care lol
Jason wong
Nope! 4 stroke...
huh ??? A two stroke is just about the easiest engine to take care of. It's always some imbecile that decides to run it "just once" with no oil in the gas ....Run 3 or 4 oz oil per gallon of gas ....dont run your carb too lean...they're pretty much bulletproof.
Enjoyed the video and the knowledge, but goddamn the guy running the camera is annoying! Thanks for sharing!
Bahahahah I fuckin lost it at "Brap Sandwich". Probably the best thing I've ever heard a Wankel called.
Neat process, I hope to make a brap sandwich powered car at some point :)
Cheers!
Nice job, i think every viewer of this video can truly say they can build a rotary engine. Through and informative to say the least! Excellent work guys!
"The uuuhhhhhhh"
I Wonder How Many Times He Said "Uhhm"
Awesome video lots learned Thanks!
Glad you liked it.
you used one word 30% of all words spoken, err.
Fake clickbait, you didn't even cast and machine your own parts.
I hope this is a joke...
This is going to get so many views.
apex128 lol 1.2 mil now
Here now
Why is there a big tub of vaseline on the table and two guys?
it seems rotary engines require 2 things. Shit load of spare parts and a big jug of lube
Might want to consider actually watching and listening to the video
Most people don't watch the entire video. At the very end, they ass-fuck each other. The vaseline helps minimize the damage.
opl500 not to mention the miata in the driveway
It's same like assembly lube on piston engines .... I watch my dad do that
Rewatching this as I'm getting ready to build my cosmo engine for my RX-7 soon and a few things I wanted to correct that were said in the video. Yes the FC and FD had water channels in the irons, but those along with the euros cosmo were the only rotary cars to ever have them there, from 1967-1985 all rotary engines had water channels in the housings and they never had water channel breaking issues like the 1986-2002 motors did, but the reason for mazda reverting back with the renesis is correct. Also lightened genesis rotors aren't the best idea if you want to balance them accurately, the problem with lightening RX-8 rotors is that there isn't enough material on them to do both. The RX-8 rotors that I'm using for my cosmo engine build were sent off to CLR motorsports to be balanced, but not lightened and that is because I wanted the most accurate balance on an already super light rotor possible which is exactly what I got. This video will explain everything I'm talking about here ua-cam.com/video/HahComhZR9c/v-deo.html .
*Also there is no benefit to porting a renesis engine, the max power to be gained from this is maybe 1-5whp, the reason for this is because it is already a near maxed out engine stock which is why dumping thousands into intake, exhaust, ignition and tuning yields very little results and all porting will net you is worse economy and lower reliability. Top that off with a pair of grossly unbalanced rotors and that's just a shit show I wouldn't touch with a 10 ft. pole, however, there is a type of porting that will increase reliability and even help exhaust flow and that is removing the carbon Catchers in the upper portion of the exhaust ports, carbon builds up in this area over time (mostly from babying the engine and treating it like a piston engine) and eventually breaks loose causing catastrophic internal damage.
Besides what I've talked about above this is a great video and hope to see more rotary content from this channel in the future
Hey thanks
You know exactly what you're talking about!👍 😏 I'm a big fan of 12as and early 13bs.
This is what people fail to see, rotary engines only have 3 main moving parts and about 30 or so other parts in total making them the most simple and easy to build and rebuild they take literally no time to build
Another engine build! 1st the air cooled Porsche, now a rotary! Love these builds, more please! 4G63 next? :D
Agreed, would love to see 4g63 tear down/rebuild content
RB26 Teardown too!
Awesome, gotta love the magic of a rotary
This is a Wankel engine... a rotary is something very different.
Stop, it's not, same thing
A wankel engine is a rotary engine but not all rotary engines are wankel. Look up a Le Rhone rotary engine.
+Keven Steeno *Which Wankel are you referring to???* _Only the Wankel DKM prototype was a Rotary layout._ (Millet Type invented by Félix Millet in 1892).
*But the DKM never saw production, 26 major engine manufacturers around the world licensed the production of the Wankel KKM design created by Hanns Paschke... Paschke dispensed with the troublesome Rotary layout in favor of a conventional rotating crankshaft and flywheel arrangement found in all production Wankel designs that were developed back in the 1960's and 70's*
I was simply saying that the term "rotary engine" covers a wide range of engines.
Very nice video! Very informative, and Educational. I'm now thinking about using one of these on my dune buggy build! I like 2 stroke motors for the simplicity and this is really a improved design of a 2 stroke, thank you for a great video, I enjoyed watching.
Awesome! Sounds like a really cool project to put a rotary in a dune buggy!
+Mike Flynn Wankel engines use the 4-stroke operating principle
There's nothing funnier than people too stupid to know what they don't know about engines repeating shit about engines you don't HAVE to know a HELL OF A LOT about engines to know isn't true all over the internet because they're "engine experts" and more importantly "rotary enthusiasts. Can you name two types of 2-stroke, Mr. Goodwrench? I mean besides "running" and "not-running" or even a tough one like "liquid-cooled" and "air-cooled"?
Don't confuse the rotary fools. We don't need them trying to learn things and getting "educated" on engines. They're already "experts". Just let them be.
You can use a torque wrench on the oil pump assembled using a crow foot attachment
I build a lot of engines, the only things I torque are the bearing ends, heads, camshaft bearings and crankshaft pullies. The rest you can do it according to bolt size and for some critical scews loctite is advised. He used the torque wrench a lot because of the Internet critics most probably!
@@st_us the reason he used a torque wrench is because he was torquing down the engine case assembly. Compared to a good ol piston engine is almost the equivalent to torquing down rod caps and main caps at the same time.
Umm, uhh, umm, uhh. - Joe 2016
Yep, another video I can happily waste my time to completely watch it! 👍
16 years of experience.. This guys is True Rotary Master
Seems like the rotors need to be installed in a specific position for timing purposes but I didn't see Joe mention anything about timing marks. Hmmm....
10:00 "I need to stretch it out a bit"
"Aww yeeahhhh?" 😂
The reason for getting rid of the exhaust port holes in the rotor housing: Apex seals tear off the coating of the surface ( chrome on 12 A, Nikasil on 13 B ) at the edges. My first 12 A died because of this. No emission rules involved this time.
STOP SAYING "UMMMM"... "UHHHHHH"... "AHHHHH"... "UHHH" for the love of God, I beg you...
FightClub MeetsHere
I'm glad i'm not the only one that feels this way. The uuhhhh and uuuummm makes the video very hard to watch.
But you have to remember, they're rebuilding an engine, trying to talk And explain what they're doing. I'd say uh and um too
I was going to leave a comment that says can somebody please edit this video and delete or add a fart noise every time he says UHHH or UhMM? That way you know hes having a brain fart when it happens and its funny instead of annoying. Lol
It’s pretty safe to say at 30 years of age Joe looks like he knows what
boost goes in apex seals go out
Not ceramic seals they hold boost much better
ok that was too funny
if you can afford ceramic seals, you can afford a better engine
HenryMania by better engine you mean more rotors? xD
+FatalvenomX No, one that is not obsolete...
Definitely changed my outlook on rotary engines
It’s easier to put the rotors on first then the housings and you don’t have to put the key way in to check the end play- this all saves time
im really surprised at how these guys don't have closer to 500,000 subs. great content
We're trying hard! Tell your friends :)
Like there's 500,000 rotary fans too clueless to "build" their own engines who are going to go on UA-cam to "see how its done"? Has Mazda built 500,000 RX cars TOTAL?
Yep, mhmm, yep, yep, mhmm
RIP Sears :,(
I just bought a 1988 rx7 as my first car today, it has been sitting for 5 years and dosent run now but it did 5 years ago.
Does it run yet haha
can you build a 4 rotor out of it?
YS Lim yeah in theory its not that hard but personally i dont have any experience check out a video about building a 4 rotor
YS Lim eccentric shaft is custom made and a little expensive.
you'd need 2 of those engines, custom made eccentric shaft and counterweight and it would be just as shown here (but 2x the job)
it sounds simple afaik only aussies custom make that stuff and it costs A LOT (10k+)
Error989 Why do you need counterweight?
YS Lim to balance the rotations and make it smooth. It would jump all over like a washing machine with a brick in it if it didnt have one :D (well not that much but you get what I mean).
*This month marks the 10 year anniversary of Mazda's decision to pull the plug on the RX brand and discontinue development of Wankel engines... the last production RX engine was unveiled 25 years ago.*
en.wikipedia.org/wiki/Internet_troll
I'm such a dreamer, this had me looking at rx7s on Craigslist. We'll see..
I was looking at repus
+Camhin1 look for an rx7, repus have a 12A engine which cannot get as many aftermarket parts as the MUCH more popular 13b
zachary6656 But the Rx7 isn't a ute and I can always swap it.
Honestly I would of thought that the rotary motor would have been harder to put together but it looks pretty simple.
99% of the work is in rotor prep and other parts prep. They call this "the build" but really doesn't contain much of the info that leads to a great motor.
A "great motor" would have _reciprocating_ pistons
You're a fucking tool lmfao never even owned an FD Rx7
In a car meeting, when the rotary engine comes, all the bullshit stops!
Rotary is the real “neck breaker” Hehehe
those rotors are $2,350. I can only imagine the acceleration to be had with both the lightened rotors and racingbeat lightweight flywheel plus it's street ported too so this engine will be very badass with a proper tune. I just have the flywheel that i'm using with my S2 drivetrain swapped S1 and that should be pretty decent on it's own, but once it comes time to rebuild the engine i'll be sending the rotors off to be lightened which I believe the cost to do so is about $600-$700 each. Anyway, hope whoever this engine goes to takes good care of it and beats the shit out of it regularly
It will break down again soon... just like they all do. If Mazda couldn't fix all the reliability flaws no one can... and that's why Wankel engines are no longer sold.
@@doktorbimmer no its not. Emissions are the reason why there are no new rotary cars. An engine that injects oil into the combustion chamber cannot meet current emissions regulations. Second, they are still sold, just not in cars. I just ordered a 13B-REW from mazda last month to replace my bridge ported one. Old engine is fine, but is a track engine and way to loud for the street.
Its always people who never owned a rotary or know how to maintain a car that talk shit about them...
@@surrrithux Bullshit, Wankel engines are obsolete because people refused to buy these horrible unreliable, inefficient and overall inferior engines.
The "Emissions Myth" is very popular among the rotards but completely falls apart upon the slightest scrutiny.
should make a video on clearances and techniques used for getting them right. also more in depth on turbo clearance numbers vs NA.
Can't believe Im about to tell a racing engineer that he is putting his apex seals in wrong....
Sidney Well...did you tell him?
I really enjoyed the video, demonstration, and step by step that Joe performed. All the jokes on the other hand, I did not. Dave does a good job with extracting information out of Joe, on details that are second nature to the veteran builder, but keep it technical.
Uh uh uh uh uh, thank you for the uh uh recommendation youtube
The most fascinating thing about the rotary engine is that it will reliably run for exactly the same amount of time it took to assemble it..
another comment by someone that hasn't got the foggiest idea what he is talking about !
Rotaries are actually highly reliable.
GREAT VID!!!
1. I thought my friends and I were the only ones that loved the Sears catalog....lol
2. I've had several rx-7's. All 84 and 85 and loved them!! I never had a problem with them and I ran them pretty hard
3. Vaseline? I never knew. I love the rotary even more!!!...LOL
4. GREAT JOB!!!
5. LOVE THE 52MM SOCKET!!!!
Thanks for the info and vid!!
Keep it going!!
didnt know these motors were so easy to put together.
American Monster Garage that was my first thought also...
Well resurfacing and prepping was done off screen. But as far as assembling. Easy.
Must be lubed by rx7 owners tears
step 1: throw it in the trash
i love how they are trash talking rotaries the entire time they are building one
They need to perfect this engine I truly believe this is the most optimal design and only true competition to the standard piston engines everyone drives
It's always such a pleasure watching someone who really knows what he's doing. Two thumbs up...
It's 54mm. NOT 52mm
Just in case anyone else wants to buy a $50 52mm socket just from taking his word for it like I did
Storm Anderozzi I've used a pipe wrench before and it works just fine
congratulations guys, I just have one question, how do you fix the crankshaft to tigth the nut ? do you have a special tool or what si you do to hold it ? thank you,for your experience.
Really want to get into building rotary engines
Can u make a video of u resurface the housing
mhmm.
A rotary engine is a one-stroke engine. It only goes one way. Might kinda sound like a two-stroke.
All Wankel engines use the 4-stroke operating principle
Built heaps of cylinder engines, but never a rotary. What have I been wasting my time doing?!?!
Building heaps of cylinder engines. That's what you've been wasting time doing.
Nice demo. Makes it look easy but in reality you have to be pretty good to assemble a rotary! (correctly)
I'm not sure why anyone would dislike this video... I loved it... simply amazing... I wish it showed the full build.. like dropping it into the car and cranking it up
Worked occasionally with Joe at RPM a number of years back, wisest rotor-head on the continent.
Thank you for double clicking the torque wrench everytime.
The original ones like the 12A also had the seal grooves in the rotor housings like this one does but they also had double side seals and fat sintered single piece apex seals. I would love to put a 13b or even a 20 in my old RWD Isuzu Impulse.

Here is where it gets tricky though. A car is not rare because of the parts that come on it. Those cars listed are rare because of the vin number showing that they are the models that would have come with the rare parts they have one them. Anyone could take a 10AE badge or Infini seats and put them in a base model and call it that rare model, the vin is what proves the car is the rare model and would come with those parts.
Take for example my superbee clone pictured in this thread. It was a Coronet 440. This car came with a 318 small block, common coronet gauge cluster. The vin was WH23 because of this being the model it was. The Superbee is the exact same car. All the parts are the same, the car is identical outside of the motor it comes with is a 440 big block and it has a circular gauge cluster and a bee emblem. The vin for it is WM23. All the rest of the numbers tell about the plant, the colors, etc. However the model difference is only provable by the vin. The body panels for a superbee and coronet 440 reads the same through out the car.
So when I started learning about this car I realized how rare it was. While it ranks third in place for rarity in model, the car itself is the rarest by vin numbers. Let me explain how this is...
The 1100 GTUs models that were made are actually grouped in two categories. There are 100 that are made with the original Turbo II vin. Then there are the 1000 that had a NEW VIN NUMBER given to them making them no longer the turbo chassis vin numbers, but the GTUs specific vin. The GTUs turbo chassis models are K stamp. The GTUs non turbo chassis vins had a "X" put through the "K" and a "L" stamp issued. These are different models of the GTUs.
Here is another example of what I mean. The GXL was made from 1986-1991, there are two series of them, the S4 86-88 and the 89-91 S5. The vin number shows the difference in the different versions of that same model.
Another example is the Final edition vert. Say I got a s4 vert, put all s5 parts on it and then badge it as a final edition 92, the only way to prove it is not is the vin, the reason it is not is the vin.
Vins make the car rare, they make the swag and models rare. So that got me thinking. How many are left??? I asked around and that is how I came to realize that there are only a few left, this car is VERY rare and I am glad to be saving it from the salvage yard it was destined for!
