Rob you've gotta go on vinwiki and talk about getting the 4 rotor stolen and the build when it's done. This would make a great story on there too how you swapped and snuck a rotary vette into LS fest and the reactions you get.
Mr rob.... Mazda put all those washers there because those bolts are the correct length for the motor mounts. They need to tighten them to seal the pan so they put all the washers to make up for the thickness of what would be the motor mounts. They're including new motor mount bolts for you =/
I have heavy Anxiety about the o-ring on the back of the front cover.... I saw not checked or installed... If you run it with no o-ring will have no oil pressure. PLEASE CHECK NOW
14:55 is how you displace front needle bearing assembly and grenade the entire engine. Make sure to check your shaft end play before cranking your engine.
Exactly, he should it keep the eccentric shaft from rolling back before removing the front eccentric shaft pulley. Don’t ask me how I know but if the front needle bearing comes out of alignment then the reinstall front pulley will pinch the inside corner of the needle bearing thus resulting in engine failure soon after a few hours after starting the engine.
I really love this build. Let me say that I am the guy that dreams to have an FD one day and if I had my dream come true it would have an ls swap. But because of that is why I love this build. A rotary's "brap" is badass, and your putting it into a car that I haven't seen one in. It's going to be so awesome. I wish you luck with rest of the build and future builds. Can't wait for each new video. Thanks bud
Girls love guys like Rob. Patient, and always willing to put in the work even when the project is constantly giving him problems. Quality traits in a man lmao
Man, these builds are awesome! I can't wait to see these at LSF, and finally meet the legend personally! Watching these builds makes me more desperate for a car I can build like that, lol. I know I can do it, I just don't have the tools, and space lol. But it also inspires me to make something custom like that. And I mean custom as in, special made parts, custom frame, never done before stuff, that you can't buy your way out of. Awesome work man! love the builds!
nope someone else already made one ( sbc 350 v-8 / or v6 probably using Oldsmobile tornado transaxle parts ) ( it was slower than stock by my memory / kinda junk ) besides the factory prototypes ( came out awful by corvette godfathers standards not just the bean counters ) and at this point Chevy doesn't do 70s ford panteras ;)
Put it together, take measurements, mock it up, do modifications, take it apart, repeat 4-5 times... Tedious... but it reduces the guesswork and with better results! I'm diggin' this build!
Did I miss something, but I don't recall seeing the strengthening mods to the subframe/engine mount after cutting out all of the bracing to clear the oil pan. That would be interesting for us viewers. Enjoying the series!
they just used those washers as a stand in for the motor mounts rob. since they wanted to send it with the correct length bolts for the motor mounts to just be put on directly idk if you realized this later but i figured id let you know. also that thing inside the eshaft is called the thermal pellet it controls oil flow based on temperature you probably didnt notice on the 3 rotor because it likely had a solid thermal pellet its a common upgrade since the factory ones can fail.
Rob that part you're talking about at 10:43, it's an oil thermostat. If it fails, no oil is sent to the rotors. It's common for rebuilders to replace it with a thermal 'pellet', so maybe that's the reason you didn't see it on the 3 rotor.
Since ya have the engine solid mounted you can mount the accessories to the chassis. Mounted backwards from the front of the engine. I've seen this several times and it works extremely well
Rob Mazda placed the washers under the motor mount bolts so the oil pan would be sealed properly and with that done you also get a New set of motor mount bolts..win win..also when you bolt the front cover to the lower cross member it becomes a stressed member with the chassis..
Fun fact Mr. Rob 11,000 horse power top-feul dragster engines are usually held in the chasis tubes by two hard mounts & regular turbo hose clamps research that my friend. Coming from a Puerto Rican rotary engine nut lol !!!
it's correct in pitch, the other angles being roll and yaw longitude (front-back) lateral (left-right) vertical (up-down) would be the directions so you can say it has the right vertical position if you want
Hey Rob junkyarddave was working on a billet block of plate for that oil pump on the front cover, I'm not sure if they're done but he did have a prototype or 2.
You do realize 88 13 B motor mounts bolt up to the bottom of the middle iron which would be a lot stronger and may line up with the vet fram better because they would be further back.
1st gen rx7s have been using those front covers with massive power for decades. I think it will be fine. But now that you have a 2, 3, and 4 rotor you need to add a 12a to your collection.
When your finally done with this project your should take the vette in for service at a few local dealerships and tell them it’s running funny just to see their reactions.
The oil thermostat in the e-shaft turns off the oil squirters in the rotors until the engine warms up. They can fail from time to time, so most serious builders will delete it. FWIW, I've never liked using the front timing cover as an engine mount, but my 13T has been hanging from its GSL-SE front cover for almost 20 years at about 350hp, with no issues.
Oh wow. Good to know. Explains why I wouldn’t have figured that out when moving to front cover engine mounts. Learning something new. It’s been a long time since I pulled my old 2 rotor out briefly
Dahm Rob, you need to buy some work benches! I have no idea why people work on the floor when it is so easy and cheap to setup some sort of table. Even some saw horses and a sheet of plywood could be a great place to lay your parts while working.
You guys need to take it easy with the RTV. There's an entire bead hanging on the inside edge of the oil pan and the mating surface of the keg. That stuff can clog the pickup and starve your engine. Speed Academy blew up their S2000 doing that...
10:44 you didn't see it on the 3 rotor because its a oil restrictor for emissions to cause the shaft to heat up with friction on cold start. For custom rebuilds this spring is removed and replaced with just a spacer allowing oil to always flow because no one likes their shaft chafing without lube.
Hey Rob! Have you considered using an accusump system for this build to help save the front bearing on this? Also, at high rpm if there is a drop in oil pressure, it will save your engine
hey Rob you should measure the front of the frame to the ground and then measure it with each large piece you install and see how much each part weighs so you can catalog each part that goes onto the car. this way you have kept track of everything. then you'll see the difference in LS front engine parts and stuff pulleys and everything it all adds up! might surprise you what the overall end result will be with differences in weight. also did you weigh the car with the LS in it before you started?
Aliens are going to find Rob Dahm’s shop 10,000 years from now and be so confused as to why this man worshiped triangles
Kyle Keogh no hes been runing with then every sence he loved rx7's which were built Illuminati
4 rotor still unfinished by then too
Not likely. Egyptians communicated entirely in emojis.
Sky Guy hahaha lol fuck man thats some funny shit right their👉:)
Illuminate shit for real son
Rob you've gotta go on vinwiki and talk about getting the 4 rotor stolen and the build when it's done.
This would make a great story on there too how you swapped and snuck a rotary vette into LS fest and the reactions you get.
I completely agree with every part of this
Beta Rob was on a few times. It's time we get some alpha Rob on vinwiki
The UPS man was a shrewd negotiator.
Mr rob.... Mazda put all those washers there because those bolts are the correct length for the motor mounts. They need to tighten them to seal the pan so they put all the washers to make up for the thickness of what would be the motor mounts. They're including new motor mount bolts for you =/
Was now gonna say something
I'm only watching videos with juice commercials at the beginning. Unsub.
better than a pepsi ad
Its nice how fast things move when you dont need to rely on other people
It's called editing ;-)!
@@Jimidan1000 thats not what i meant. Projects get put on hold when you have to rely on someone else's schedule
very true comment. this goes for everything in life. do not rely on other people
It’s always waiting on custom parts that makes builds take forever
I have heavy Anxiety about the o-ring on the back of the front cover.... I saw not checked or installed... If you run it with no o-ring will have no oil pressure. PLEASE CHECK NOW
Alex Ander he’s replacing the front cover with a billet one, so it will all come out again.
this project makes my bipper touch my zipper
They have loads of washers because that’s where the engine mounts bolt too and they are as thick as the washers....
I can't believe Rob didn't reply to this.. Yup, they are the proper length bolts. You got what you ordered Rob, not what you wanted.. Hahaha
Now you can say its a mid engine corvette 😂😂
Mid engine AND rotary lol
In an alternate universe there is Rob and Jared putting a Mazda v8 a GM Rotary Corvette
Slightly Happy nah, he’d be putting the gm rotary in a v8 rx7.
Lol wtf hahahaha
pre-80s gm actually made a prototype rotary powered by pratt & whitney 2-rotar but couldn't get it to run because of the apex seals burning up
watching you work on the rotary vette is just watching you guys clean up constant spills

I love hanging out with Rob, that's what it's like with these vids lol 😂👍👍
Girls love guys like Rob. Patient, and always willing to put in the work even when the project is constantly giving him problems. Quality traits in a man lmao
Where are said girls at?
You are the ultimate mad lad by putting a rotary in a Corvette.
Probably the only person I actually like to watch keep it up man doing great
Best build on UA-cam. Can't wait to see the reactions at LS Fest!
Really cool to see the progress you're making, I hope you get it done before LS fest...but we know how you are with timelines.
I’m pretty sure you’re going to need coil overs on the front there to get it down to a normal looking height.
Pretty good for a guy who cut his own hair. 🍻🇨🇦
you enjoy jersey shore?
Dance Around The World I enjoy Lake Ontario
I do, and I'm pretty good.
This has got to be one of the weirdest builds on youtube and I love it.
Man, these builds are awesome! I can't wait to see these at LSF, and finally meet the legend personally! Watching these builds makes me more desperate for a car I can build like that, lol.

that little brass springy thing u didn't know off the cuff is the thermal bypass pellet ezpz now u owe me the engine
Sooo, is this now the first mid-engined Vette before the C8 comes out. ;D
nope someone else already made one ( sbc 350 v-8 / or v6 probably using Oldsmobile tornado transaxle parts ) ( it was slower than stock by my memory / kinda junk ) besides the factory prototypes ( came out awful by corvette godfathers standards not just the bean counters ) and at this point Chevy doesn't do 70s ford panteras ;)
100/100 for remembering were every bolt goes 👏👏👏👏
Put it together, take measurements, mock it up, do modifications, take it apart, repeat 4-5 times... Tedious... but it reduces the guesswork and with better results! I'm diggin' this build!
Can't wait to see the engine in the bay with the front end put back on.
I'm still waiting for the rotary Lincoln
alexlam24 and I’m still waiting for the rotary Volvo truck
I'm still waiting for the rotary Honda
I'm still waiting for the rotary Challenger
I'm still waiting for a rotary...
The moment those tires touched down, thousands of Vette Bros screamed out in terror!
Glad you’re getting more support for your builds man👍
I still can’t get over how much room you have in that engine bay 😂
so much room for activities
F r u n k ?
this style of content is awesome, kind of reminds me of early B is for Build
I can't wait to see this car going on it's own power
I love the no intro just straight into the action
love you rob dahm
If everything was done correctly we wouldn't have unique builds like this. Thanks Rob*
The engine needs to be easy to get to cuz you gotta rebuild the bastard so much
Did I miss something, but I don't recall seeing the strengthening mods to the subframe/engine mount after cutting out all of the bracing to clear the oil pan. That would be interesting for us viewers. Enjoying the series!
Loving these longer videos they have been top notch quality content. We also need more epic commercials at the beginning had me dying last video.
Your impact gun is a drill now lol I like the raw mechanic skill you have and your still not afraid to tear things down cool 😎 lol
they just used those washers as a stand in for the motor mounts rob. since they wanted to send it with the correct length bolts for the motor mounts to just be put on directly idk if you realized this later but i figured id let you know. also that thing inside the eshaft is called the thermal pellet it controls oil flow based on temperature you probably didnt notice on the 3 rotor because it likely had a solid thermal pellet its a common upgrade since the factory ones can fail.
Rob Dahms Rotary Corvette vs Cletus' Auction Corvette
Have you seen the recent turbo upgrade on ruby?
Rob that part you're talking about at 10:43, it's an oil thermostat. If it fails, no oil is sent to the rotors. It's common for rebuilders to replace it with a thermal 'pellet', so maybe that's the reason you didn't see it on the 3 rotor.
One day I will see you dyno tune that freaking 4 rotor!
Since ya have the engine solid mounted you can mount the accessories to the chassis. Mounted backwards from the front of the engine. I've seen this several times and it works extremely well

Put studs, as deep as possible, in the front cover for the engine mounts.
it's correct in pitch, the other angles being roll and yaw
longitude (front-back) lateral (left-right) vertical (up-down) would be the directions so you can say it has the right vertical position if you want
1:46 Rob the type of Dahm to have a 4-rotor willy
The bar for rob dahm intros has been raised once again
I’ve learned so much watching you thank you !
gm was going to make a rotary corvette back in the early 1970s mid engine as well
Short haircut Rob should totally start recording a series on ebay power mods for the little honda
My mind is still blown by the fact that the front suspension is just like one leaf spring.... holy shit!!
Huge congrats man. Keep wait to see it at LS fest
That one little part killed it lol
Hey Rob junkyarddave was working on a billet block of plate for that oil pump on the front cover, I'm not sure if they're done but he did have a prototype or 2.
So the rotary engine goes in the corvette , and the ls engine goes in the mazda and the Wornout rotary engine is a grape press !
Nice shirt, bought mine a few weeks ago when they came back in stock. lol "7 Generations"
Plz rob do the most agressive possible porting on that rotors 😍
Looking good boys!
20:55 That longbow edit.. 😂😂😂
Love watching your vids while on the treadmill, makes me forget im exercising
You do realize 88 13 B motor mounts bolt up to the bottom of the middle iron which would be a lot stronger and may line up with the vet fram better because they would be further back.

Love the haircut hehe
Comin along. Holy shit. Can't wait.
That intro made me a subscriber.
ROB BUILD THE 4-ROTOR!
On the throttle channel they got a aftermarket bracket for the fd that takes care of the over tightening of the pulleys you should check it out
Question. Will all those parts be going back into the car?
The oil thermostat in the e-shaft turns off the oil squirters in the rotors until the engine warms up. They can fail from time to time, so most serious builders will delete it.
FWIW, I've never liked using the front timing cover as an engine mount, but my 13T has been hanging from its GSL-SE front cover for almost 20 years at about 350hp, with no issues.
I'm impressed, that low center of gravity and lower weight should make the Z06 superior to it's LS counterpart.
This build is so funny. I love it!
PUT THAT LS IN THE FD. DRIVE IT LONGER THAN A WEEK
The all new 2019 Chevrolet Brapvette. It will be nice when it shoot fireballs.
Rob I hope you go to LS Fest dressed like the stereotypical vette owner with the jean shorts, white new balance shoes and gold chain.
I think you should consider swap to coil over suspenssion..OEM setup its for a heavier engine..
Rob, Mazda used the right length bolt, if you attach the engine mountings at the rear that’s where they fit, on those long bolts.
Oh wow. Good to know. Explains why I wouldn’t have figured that out when moving to front cover engine mounts. Learning something new. It’s been a long time since I pulled my old 2 rotor out briefly
Rob Dahm I just pulled my 13b and teared it down,so I’m on top of my 2 rotor game 😉.
Oh yeah Mazda loctites the front bolt in. That’s why it’s so tough to remove from a stock motor.
Damn these first scenes that keep making me laugh my ass off..
Dahm Rob, you need to buy some work benches! I have no idea why people work on the floor when it is so easy and cheap to setup some sort of table. Even some saw horses and a sheet of plywood could be a great place to lay your parts while working.
Alright, I want to see them run, at least one of them
How is rob not sponsored by Doritos already?
You guys need to take it easy with the RTV. There's an entire bead hanging on the inside edge of the oil pan and the mating surface of the keg. That stuff can clog the pickup and starve your engine. Speed Academy blew up their S2000 doing that...
Dam Rob what did you do to your hair ! Lol I know I saw the vid explaining the hair situation.
10:44 you didn't see it on the 3 rotor because its a oil restrictor for emissions to cause the shaft to heat up with friction on cold start. For custom rebuilds this spring is removed and replaced with just a spacer allowing oil to always flow because no one likes their shaft chafing without lube.
i dont know everything i just pick this stuff up, like the oil pressure do hicky and the water release plug from yesterday
now that i think about it rob does look like the green arrow
When this car was puttet to the ground and Rob wiggled it a little, i thought there will be joke as "now it has a rotary, now i can push this" XD
How about an elite rotary shop intake manifold for the Vette?
Can't wait for this car to be done it's going to be fucking awesome. Also is this going to be E85 I can't remember if you said it yet?
Hey Rob! Have you considered using an accusump system for this build to help save the front bearing on this? Also, at high rpm if there is a drop in oil pressure, it will save your engine
Surprised you don’t like the RX3, that thing was rad!
You could install the mother of all V mount setups in the vette.
Rob is the new green arrow, he even got his hair matched.
This is getting better and better... How the fuck do you make good content like that? One of the best car channels atm by far ;)
16:20 BadObsessionMotorsport would be like “make the noise!”
hey Rob you should measure the front of the frame to the ground and then measure it with each large piece you install and see how much each part weighs so you can catalog each part that goes onto the car. this way you have kept track of everything. then you'll see the difference in LS front engine parts and stuff pulleys and everything it all adds up! might surprise you what the overall end result will be with differences in weight. also did you weigh the car with the LS in it before you started?
