A few years ago. I was at a big car show in Indianapolis. There was a gut that had a very early Valiant. He had a turbo'd slant in it. He used a Clifford 4 bbl aluminum intake. And the turbo, throttle body injectors, and computer from a Buick Grand National. He had a 5-speed in it. The car looked completely stock, Even dog dish hubcaps. And as he said. "I piss off a lot of Mustang and Camaro owners with this. It was very cool
I love builds like that. I was at a SDAC meet years back and saw a red ‘88 Shelby Z someone had put a 340 in and with the hood closed it looked absolutely bone stock right down to having the factory center console and shifter.
I had to look up your "From Buick With Balls" article. I must admit, a big smile broke out on my face when I read this, "𝐵𝑢𝑡 𝑡ℎ𝑒 𝑝𝑒𝑜𝑝𝑙𝑒 𝑤ℎ𝑜 𝑠ℎ𝑢𝑛 𝑡ℎ𝑒 𝑖𝑛𝑡𝑒𝑟-𝑐𝑜𝑜𝑙𝑒𝑑 𝑚𝑒𝑛𝑎𝑐𝑒 𝑡ℎ𝑒 𝑚𝑜𝑠𝑡 𝑎𝑟𝑒 𝑜𝑤𝑛𝑒𝑟𝑠 𝑜𝑓 𝑙𝑒𝑔𝑖𝑡 '60𝑠 𝑖𝑟𝑜𝑛.

That's some good writing right there, Tony!
Oh boy, this is going to be the best one yet. Maybe consult with David Vizard about where to cut the unnecessary weight off the crank. "From Buick With Balls" was THE reason I put an 80 Regal turbo setup on my 76 Sunbird odd fire V6 instead of the 69 350 Chevy bellybutton I had setting around. I didn't know Uncle Tony was Tony Defeo for months. This is like being 18 again.
Tony....I've played with turbos since 1984 when I bought a(supposedly) blowed up '79 2.3 turbo Mushtang.....then there was all the Buicks and Pontiac's and....on and on....That turbo T/A pace car was FAST!!! lol Water/alcohol injection will be your best friend on this one, Tony!!!
I have had many tower of power engines over 40 years, and have found them to be a work horse engine, almost impossible to kill, but they also can make great power. Way back, Chrysler built a race version of this engine, around 1960, 61 for a class of econo class racing, kicked but against Falcon and Gm. 6 cylinder engine of that time. Treat them as you would any race / high po engine and you will not be disappointed.
That was the short lived NASCAR compact car series. Valiant wiped the floor with Falcon, Corvair, Volvo, Rambler, everybody. That is why Bill France cancelled the series after only a few races. Stock car builder Smokey Yunick said the slant six responded to a few simple modifications, more than any other motor he ever saw. This is the one he was referring to. The 1961 Hyperpak kit you could buy from your local Plymouth dealer for around $400 bucks. Cam and valve spring kit, intake and 4 barrel carb, header, exhaust, and heavy duty clutch. Took the 170 cu in slant from 101 to 148HP.
Actually a straight six is a bunch easier to trubocharge than a V style engine. And if you get it right you have a huge horsepower and torque gain. There are quite a bit of youtube posts where they boost a straight 6, for some strange reason it seems as if the king of the hill is the Ford 300 for the boosting. I think the slant will like it a bunch.
@@thomasheer825 the 225 is every bit as hearty as the 300, just smaller. One of the reasons cummins made their pickup engines a straight 6 is more engine for the buck with the turbo setup vs a v8
I built many Ford inline sixes. My favorite was the 170, 200 cu. inch motors. With three Holley carbs, good head porting those motors ran really strong.
The 170 in Australia had a non removable intake manifold so I never saw one that was modified. It wasn't until the late 70s that we got a Ford inline six that was amenable to hotrodding but that came with crossflow head and fuel injection. Even a mildly worked over crossflow would run quarter times quicker than the legendary GTHO Phase 3 which had a stout 351 Cleveland.

4:00 I just went over and reqd that article and the sidebar. Amazing writing Tony! Time traveling 6th fleet vs old timers with 6 shooters...nice work!!
UT, don't go wild with the cam. The Chrysler 2.2 and 2.5L turbo 4 motors use camshafts with very little overlap, the reason being you will just be blowing fuel out the exhaust pipe. And that exhaust pipe should be 3 inch stuff all the way back with smooth bends, no ripples. You also need to control that boost so you don't exceed safe limit. Timing should be carefully mapped. Detonation will destroy your pistons, which should be FORGED units. An intercooler with good flow thru is also a must. I learned from experience. Compression ratio should not exceed 8.5. At 12 pounds of boost you may be at about 13:1. ( guessing ). I'm excited about this one. Good luck.
Tony,I have a friend in Orlando with an 8-second turbo'ed Supra street driver. He has a bottle on it but it's NOT plumbed into the engine. It sprays onto the backside of the turbo to spool it up. (Now,the seed is planted...) 😁

I actually commend you on your speaking skills and presentation skills. You never say "um um" or whatnot. Your speak pretty much unscripted, except for I'm sure a goal in mind for the topic. I love how each of your cars or projects have a designated purpose and build objective (street rat, gasser). Anyway - greetings from the other side of the NJ Tpk.

There used to be a guy with an early 60s Valiant slant turbo who raced at our local track about 25 years ago. If memory serves, I think he ran low 11s or high 10s... that was a wild little car!
I appreciate what Cletus, KSR and others have done with turbos, electronic fuel management, etc and its amazing how quick they are running, but for the average hobbyist, its not for most. Analog and mechanical works and is easily to diagnose while the other stuff goes over my head, too many parameters for the average guy. Cant wait to see the results of this build!

I wish I knew a quarter of what this man knows. Lol. Amazing just listening to him. Back in the day if I was his neighbor, as a teen ,he would haveta run me off physically, cause I would want to learn everything . Someone missed out lol.
Many are discovering the wonders of the classic inline sixes from the Big Three (including AMC if one must be technical with the Jeep I6 engine). A particular show has boosted the Chevy and Ford engines with amazing results. I do wish that the aftermarket started making support in order to hotrod these engines. Particularly aluminum cylinder heads. Edelbrock makes heads for the Jeep engine. I recall seeing a video where homemade ingenuity have resulted in a race Ford 300 with cut and modified small block Ford V8 heads. (Can't recall if they were Windsor or Cleveland heads.) Someone ought to 3D scan such a Frankenstein head to make bolt-on aluminum heads for said Ford. Same principle for the Chevy Blue Flame and Chrysler Slant Six. It may be a niche market, but I'm sure there would be interest for aluminum cylinder heads for these engines.
I have a friend that road raced his 66 dart with a slant six. I think that the biggest issue with running them at a higher rpm is the oiling system. Mainly the meshing of the oil pump to camshaft. I think just using a single stage external oil pump would help a lot.
Hey Tony, Tim here, BOOST THAT SLANT!!.....i've NEVER heard of a turbo slant......never........i like the idea of keepin the forged crank!!...heavy or not, when boost comes in, we need STRENGTH!!......or u'll see internal parts, u dont wanna see........i will keep a close eye on this endeavor.......shud be a boat load of fun!!.....my '76 Volare slant was a pile.......if u helped me, it wudda been much better........sounds like fun!!....you and Stoob get it rockin!!.....love it!!......PEACE my brother!!
I used to think like you UT. Na all the way. Then I went procharger... NA is long in my past. Once you own a boosted engine you just never think about not boosting again.
I have a copy of MM&FF that I believe you wrote an article for in 87/88! I could have the date wrong but either way I was either negative 1 or just born in 87 and that is how I first heard about Tony DeFeo from reading a magazine that I found when I was 12 years old at a garage sale when I was super into Fox body mustangs now all these years later I feel like I could call you a friend even though we've never met but I've had you sign some stuff for me! ♥️ love you Tony! I literally cherish my signed Uncle Tony's garage t-shirt! I did burn a small hole in when I was doing some welding not realizing that I was wearing it so hopefully I can get another signed shirt from you so I can hang it up cuz you are seriously a living legend!
I've seen the same smile on Uncle Tony's face when he bought the harley 883r...turbo slant 6 will be an interesting build for sure.would love too see it in plan z🤘
For a street car I like the combination of an inline engine and a turbo. What got me into this was Ak Miller was selling a kit for the 6 cylinder engine in the early '60's Ford Falcons. Since I was seriously considering buying it, but had reservations about the rather mundane economy engine with a turbo, I called the number on the ad and to my surprise and delight spoke to Ak himself. He said "This kit will make that little puppy fly". Or something like that, but he also explained why it works. The kit was simple. As you say, all analog. No fuel injection, no heat exchanger, no wastegate even. It had something that shut the flow of air to the compressor when it got too much pressure built up. Simple. You may already know this, but Ak liked propane for fuel too. But that is another story. This combination works well be cause these pushrod inline sixes have low end torque. Then with moderate boost from the turbo, they get some more power where it needs it. A little further up where the power falls off. And the kit and plumbing on an inline six is simple. I never did get that turbo kit. I'll be watching along.
I remember adding a direct connection windage tray to my 67 Power Wagon. I think it was rated for an additional 15 horse. On a side note I remember running open exhaust for a minute, it sounded like a cross between bottom hole detonation, jake brakes, and a jet engine, when you left off the gas. LOL
@@fastinradfordable they do add power, it's Mopar why they added them on 340s. You can't froth oil without friction, which means work and energy from the engine Is being used to fling oil at very high rpms
I like the Slant6.. since I drove one for many years daily.. I will say, you will have time to plot .. just how fast you want to go, if possible.. on the freeway.. but a happy little motor.. Twins in my life Hers still Slant6, Mine has been 318 swapped and has 70k on it now, True daily driver both 68 Dart
I never realized the slant 6 was used in the U.S until the early 90s, we were done with it here in Australia by 1970 and it was replaced with our hemi 6, (only in name, it was closer to a polysherical head). N/A they were a beast, let alone a bit of boost. Valiants here always had good drivelines except we got no big block cars........which is sh#t
Turbo with a blow through carb will be fun. Just put enough cam in it to drop the boost pressure and increase the NA power. Could be fun and run 10s with it.
If you want to do a turbo car.I highly suggest a Gen 1 or 2 DSM (Eclipse,Laser ,Talon) or something like a FWD Chrysler turbo car like a Shelby Charger,Daytona ,GLH.Believe me you will have fun with them !
Cool info. My experience has been don't be afraid of a narrow lsa cam with the turbo, it will provide good torke for a limited rpm engine so long as one doesn't mind a ruffer idol and low vacuum. Long stroke engines seem to work well in the 108 range
I don't remember who but somebody (bodies?) involved with the slant six drag racing series/Slant Six Racing News back in the early 2000s had gone to the trouble to make a sheet metal crank scraper that sandwiched in between two oil pan gaskets. The extra clearance of another gasket would aid your quest for more rotating clearance too. Just a thought.
I've got a turbo 318 1972 satellite I've been building for about a year now love turbo mopars and you don't need to go nuts to have fun love the info if you need boost info I'll try and help
Tony I built a turbo Jeep Wrangler with a 2.5 engine on a bet. Works like mad, the problem is that the AX-5 isn't the best transmission combination. Actually wasn't all that difficult to build, the biggest problem was the hot side, the exhaust plumbing which was a cut and weld, the problem was trying to work by myself and getting things to align properly. First exhaust pipe to turbo stress failed at about 10k miles then got a buddy to help me hold it while I tacked it up. Has 25k on it right now and works fine.
@@howiefeltersnatch2973 Heck No, that Iron Duke was a rather frail engine, I wouldn't even think of trying that on one of them. It is the AMC 4 cylinder version of the 4lt six. They were rather stout but didn't have a bunch of goodies for them to boost the power. It was simple to replace the AX-5 with a AX15 and slap in a 4.0 six. I went my own way as they made the mistake of telling me "It can't be done". After building it I often pull a 18' trailer with 5-6k of logs on it down the road at 60mph now without difficulty, now stopping it is a totally different story.
@@howiefeltersnatch2973 There was a huge difference between the GM Iron Duke and the AMC 2.5. You can tell in a rapid glance as the Iron Duke was basically a 4 cylinder version of a Pontic V8. Valve covers were wider and lower. The AMC 2.5 was easy to spot due to they were a 4.0 with 2 cylinders lopped off, the valve covers were a dead give away. Knew several AMC mechanics at the time of the switch from the GM to their own engine. guess that there were so many issues with the GM 2.5 in not being reliable and a very weak bottom end that AMC built this engine out of desperation. The AMC engine was in their eyes FAR SUPERIOR in durability and low end grunt. About the only complaint that they had is if you overheated them you could crack #4 piston, if you fixed it soon no problem if you ignored the ticking you usually put a rod thru the block when the piston finaly said "I QUIT". The old AMC 4.0 engine was reliable and powerful, the 2.5 for it's size was powerful and reliable as the 4.0. Now the GM Iron Duke was known to become a bunch of small parts and oil on the ground if you pushed them.
What about ARP main studs, rod bolts and possibly head studs for the turbo build? Old bolts, built top end+boost doesn't seem too appealing. Idk if he's going for that 15-20lb of boost mark to really call for a copper head gasket but I'd still run head studs if I could get them
Watching you talk about turbos reminds me of Tom Selleck in the ending scene of Quigley Down Under. As he crouches next to the villain he just shot in a dual, "I never said couldn't shoot a pistol, I said I didn't like them".
If you want to ever add a turbo to a donated Japanese car I'd suggest an old Datsun 240-280-Z because there is room for plumbing under the hood , and they are light cars, + they are straight 6 's !
When the cars illustrated magazine came out I bought it or was a subscriber already. I still have that article today. I remember the picture of the scoreboard. It said something like 1385. If you don’t believe us cancel your subscription
Uncle Tony Power Nation made a turbo charged slant six with no money limit made like 400hp I think 500torque. It the average person doesn’t have that money. I like your idea do it for less money decent results. That’s cool
Please keep us updated on the Turbo Slant Build! I was going to source out a 82-87 motor to get that lighter drivetrain, but I guess boost will compensate for the running gear weight? Plus Stronger bottom end and more available parts too!
Great to see that this channel is about a very good , strong engine. I lived in South Africa for many years and my father had a 1972 Valiant Rustler ( pickup) and this was absolutely unbreakable, coupled with a Torqeflite 3 speed box, all being stock...eventually the body corroded away and it was junked !! Great videos !!
It looks as though you have a new found enthusiasm Tony. Nothing like a new project to work on that is a little out of the comfort zone. The best time to learn. Make that leap. Begin the journey and good luck.
You need to find MOPARS hyper 6 . 225 cubes , fuel injected , turboed and 275 HP , that was 1962 . Now with todays electronics it could be a lot more .
Back in the 1980s, I worked on a construction site that had a lift crane, like a cross between a crane and a forklift, that was powered by a turbocharged inline 6. It was not a high performance engine but it was over 20 years old and still going.
A friend of mine and I helped him, put a tornado 455 in the back of a bettle, nothing but motor .lol ... bad thing is couldn't get it to stop with out modifications and that's where we stopped...... Porsche brakes weren't enough.... to all that work just to tear it as ll down , subframe and all ...
🤣🤣🤣 I can't let go of the fact that all youtubers involved in some way regarding this "No name national" seems to have a sturdy wildgrown beard! Great video, as always!
I know someone in Ohio that went down that turbo rabbit hole and went threw a few of those engines with a megasquirt. He was racing a 1/2 ton 80s or 90s Ram. I'm sure he has allot of info for you if your interested?
Through Stangnet, Ford Six and Four Eyed Pride, I've seen some great cars become Piles with Bad Electronics. A good set up is the stock off the shelf bigger V8 parts that fit on the Slant. I helped a true friend on StangNet, FSP, and FEP, but I made a big mistake in the past with advice to a guy who did the Turbo 250 Fairmont. He used a 10.25 : 1 compression, but it worked great with a Big Borg Warner Turbo and he used 62-1 crank triggered EDIS 6 and MegaSquirt. Only mistake, was not high porting the Aussie cross flow 175 CFM head, and not going more radical on the cam lobe centers So Untendered advice is Unasked for, and Unhelpful, but Hi Compression, Hi Flow head with boost retard and rising rate fuel pressure to counteract the boost growth, and a nice 4bbl intake, and the early block and crank....oooh, it'll be Good. Nice to see you getting into Boosting it without I.T. again! By the way, if you ever want to go MegaJolt Ignition and just keep the Stu B 4 bbl, I know just the guy.
A lot of NA guys don’t go that much for boost because they often enjoy the work involved in making an NA package that really runs good. With boost you can make a bunch of power without having to worry about how well the heads/intake flows or what cam is in it. Sure, there’s more power in everything being well matched and optimized. But, boost really makes up for a lot of you aren’t chasing everything you can get with a certain setup.
The later slant sixes have less parasitic losses would make sense. Th a t and the 727 & 904s getting lockup for 3rd gear meant that they were quite fuel efficient, when the leanburn is working. My brother is getting about 25 from my estimates in a longbed 1985 d150.
I've got a set of oversized intake valves that have been on my shelf for the last 15 years plus an 1979 uncut 4104362 (stock valve)head with the bowls already ported (by me, not a professional but am a machinist and not my first porting attempt), runners untouched, with no slant to put it on, that can be had. Just saying Uncle....
Uncle Tony would you like to help me do a subaru WRX build? These are by far some of the funnest cars I’ve every driven and owned! I love flying through the dirt and snow in them. they are really fun!
I remember back in the late 90's when the internet was becoming popular, a website dedicated to slant sixes and MPG enthusiasts. Most of them were turbocharged, with a small turbo, for MPG purposes and competition, not performance. If I recall, most of them were getting over 40 plus MPG.
Maybe turbo a basic 318 and than step by step add a 4bbl , headers , etc Gradually see the power increase as you further modify the engine more and more.
A few years ago. I was at a big car show in Indianapolis. There was a gut that had a very early Valiant. He had a turbo'd slant in it. He used a Clifford 4 bbl aluminum intake.

I like the thought process of a certain SAAB engineer, "your motor has a water pump, a fuel pump, an oil pump.... why shouldn't it have an air pump?"
My slant six has an air pump... it pumps air into the catalytic converter to help burn off the smog chemicals

Amazing how far the world of NA has come in the last 40 years. Nowadays there are people running 13s with NA Prius engines fitted to a Yaris
I wish I knew a quarter of what this man knows. Lol. Amazing just listening to him. Back in the day if I was his neighbor, as a teen ,he would haveta run me off physically, cause I would want to learn everything . Someone missed out lol.
Many are discovering the wonders of the classic inline sixes from the Big Three (including AMC if one must be technical with the Jeep I6 engine). A particular show has boosted the Chevy and Ford engines with amazing results.
I do wish that the aftermarket started making support in order to hotrod these engines. Particularly aluminum cylinder heads. Edelbrock makes heads for the Jeep engine. I recall seeing a video where homemade ingenuity have resulted in a race Ford 300 with cut and modified small block Ford V8 heads. (Can't recall if they were Windsor or Cleveland heads.) Someone ought to 3D scan such a Frankenstein head to make bolt-on aluminum heads for said Ford.
Same principle for the Chevy Blue Flame and Chrysler Slant Six.
It may be a niche market, but I'm sure there would be interest for aluminum cylinder heads for these engines.

I'm excited for this project! I want to turbo charge my 170 Slant6 that's going into my 1918 Buick Roadster. 🔥🏁
I have a friend that road raced his 66 dart with a slant six. I think that the biggest issue with running them at a higher rpm is the oiling system. Mainly the meshing of the oil pump to camshaft. I think just using a single stage external oil pump would help a lot.
I remember your article From Buick with Balls, still have the magazine I am pretty sure

@@DragPakMerc 👍👍👍👍👍
I'm big on NA builds and horsepower. I'll admit, a 6-71/8-71 looks cool.
Hey Tony,
Tim here, BOOST THAT SLANT!!.....i've NEVER heard of a turbo slant......never........i like the idea of keepin the forged crank!!...heavy or not, when boost comes in, we need STRENGTH!!......or u'll see internal parts, u dont wanna see........i will keep a close eye on this endeavor.......shud be a boat load of fun!!.....my '76 Volare slant was a pile.......if u helped me, it wudda been much better........sounds like fun!!....you and Stoob get it rockin!!.....love it!!......PEACE my brother!!
I used to think like you UT. Na all the way. Then I went procharger... NA is long in my past. Once you own a boosted engine you just never think about not boosting again.
the inline 6 cylinder engine produces more torque at a lower rpm then a V8 of the same size. the turbo provides even more torque.
And it’s cooler.
I've done 2 /6 cars that were NA and they were a blast!
Would you want to go with a heavier crank do to the boost???
The forged material will be way stronger, and have a longer fatigue cycle life than a cast piece. 20lb sounds like a lot, its really not.
It appears to us, the viewing audience that you get excited about anything cars. That is what keeps us coming back.
I have a copy of MM&FF that I believe you wrote an article for in 87/88! I could have the date wrong but either way I was either negative 1 or just born in 87 and that is how I first heard about Tony DeFeo from reading a magazine that I found when I was 12 years old at a garage sale when I was super into Fox body mustangs now all these years later I feel like I could call you a friend even though we've never met but I've had you sign some stuff for me! ♥️ love you Tony! I literally cherish my signed Uncle Tony's garage t-shirt! I did burn a small hole in when I was doing some welding not realizing that I was wearing it so hopefully I can get another signed shirt from you so I can hang it up cuz you are seriously a living legend!
Thats the way i feel!!! I grew up reading his stuff and using it on my cars back in the day!! When i found him here it was like finding family!!!😁
That things going to be cool.
I'm also an NA guy... but I'm hella excited to see this!
I've seen the same smile on Uncle Tony's face when he bought the harley 883r...turbo slant 6 will be an interesting build for sure.would love too see it in plan z🤘
I can't believe you compared an Iroc Camaro to a Portaloo in one of your old articles 😂 CLASSIC!!
what's interesting to me is the head flow dynamics of the slant with the turbo. super neat.
Cool build!
Speaking of cool slant builds...
Where's the Miata?
Did I miss something?
For a street car I like the combination of an inline engine and a turbo. What got me into this was Ak Miller was selling a kit for the 6 cylinder engine in the early '60's Ford Falcons. Since I was seriously considering buying it, but had reservations about the rather mundane economy engine with a turbo, I called the number on the ad and to my surprise and delight spoke to Ak himself. He said "This kit will make that little puppy fly". Or something like that, but he also explained why it works. The kit was simple. As you say, all analog. No fuel injection, no heat exchanger, no wastegate even. It had something that shut the flow of air to the compressor when it got too much pressure built up. Simple. You may already know this, but Ak liked propane for fuel too. But that is another story.
This combination works well be cause these pushrod inline sixes have low end torque. Then with moderate boost from the turbo, they get some more power where it needs it. A little further up where the power falls off. And the kit and plumbing on an inline six is simple.
I never did get that turbo kit.
I'll be watching along.
CULT LEADER UTG!!!
I remember adding a direct connection windage tray to my 67 Power Wagon. I think it was rated for an additional 15 horse. On a side note I remember running open exhaust for a minute, it sounded like a cross between bottom hole detonation, jake brakes, and a jet engine, when you left off the gas. LOL
…..
Windage tray wouldn’t add power.
It would help the oil from frothing.
But it wouldn’t rob 15hp.
That’s nuts
@@fastinradfordable they do add power, it's Mopar why they added them on 340s. You can't froth oil without friction, which means work and energy from the engine Is being used to fling oil at very high rpms
very interesting to see what happens ive found slant 6's are generally turds but tough and low compression so it could probably handle some boost.
I like the Slant6.. since I drove one for many years daily..
I will say, you will have time to plot .. just how fast you want to go, if possible.. on the freeway.. but a happy little motor.. Twins in my life Hers still Slant6, Mine has been 318 swapped and has 70k on it now, True daily driver both 68 Dart
love how excited he gets over builds, a true car lover.
I never realized the slant 6 was used in the U.S until the early 90s, we were done with it here in Australia by 1970 and it was replaced with our hemi 6, (only in name, it was closer to a polysherical head).
N/A they were a beast, let alone a bit of boost.
Valiants here always had good drivelines except we got no big block cars........which is sh#t
The 225 was used through 1987 in the U.S., longer in south America I believe.
The best way around the restriction in the intake runner imo. Would love to see the torque curve on a Dyno.
I used to have a few issues of 'Street & Strip Supercar' that had your writing in it.
I have almost every issue of High Performance Mopar. Such a great mag. So awesome that it was your baby. Yes. I keep a few in the can
Turbo with a blow through carb will be fun. Just put enough cam in it to drop the boost pressure and increase the NA power. Could be fun and run 10s with it.
Whew second one here baby!
Agreed 👍 nitrous for the win 🏆 By the way High Performance Pontiac was my mag of choice for years.
If you want to do a turbo car.I highly suggest a Gen 1 or 2 DSM (Eclipse,Laser ,Talon) or something like a FWD Chrysler turbo car like a Shelby Charger,Daytona ,GLH.Believe me you will have fun with them !
Cool info. My experience has been don't be afraid of a narrow lsa cam with the turbo, it will provide good torke for a limited rpm engine so long as one doesn't mind a ruffer idol and low vacuum. Long stroke engines seem to work well in the 108 range
I don't remember who but somebody (bodies?) involved with the slant six drag racing series/Slant Six Racing News back in the early 2000s had gone to the trouble to make a sheet metal crank scraper that sandwiched in between two oil pan gaskets. The extra clearance of another gasket would aid your quest for more rotating clearance too. Just a thought.
I've got a turbo 318 1972 satellite I've been building for about a year now love turbo mopars and you don't need to go nuts to have fun love the info if you need boost info I'll try and help
We want to see project z vs turbo valiant as much as sledge hammer vs the jet. Cool stuff coming 👏👍🏻👏👍🏻👏
Tony I built a turbo Jeep Wrangler with a 2.5 engine on a bet. Works like mad, the problem is that the AX-5 isn't the best transmission combination. Actually wasn't all that difficult to build, the biggest problem was the hot side, the exhaust plumbing which was a cut and weld, the problem was trying to work by myself and getting things to align properly. First exhaust pipe to turbo stress failed at about 10k miles then got a buddy to help me hold it while I tacked it up. Has 25k on it right now and works fine.
iron duke?
@@howiefeltersnatch2973 Heck No, that Iron Duke was a rather frail engine, I wouldn't even think of trying that on one of them. It is the AMC 4 cylinder version of the 4lt six. They were rather stout but didn't have a bunch of goodies for them to boost the power. It was simple to replace the AX-5 with a AX15 and slap in a 4.0 six. I went my own way as they made the mistake of telling me "It can't be done". After building it I often pull a 18' trailer with 5-6k of logs on it down the road at 60mph now without difficulty, now stopping it is a totally different story.
GM engines that made it into all sorts of vehicles, including but def not limited to mail trucks and Fieros. Also known as the 4Tech engine.
@@thomasheer825 Right on. Sounds interesting none the less
@@howiefeltersnatch2973 There was a huge difference between the GM Iron Duke and the AMC 2.5. You can tell in a rapid glance as the Iron Duke was basically a 4 cylinder version of a Pontic V8. Valve covers were wider and lower. The AMC 2.5 was easy to spot due to they were a 4.0 with 2 cylinders lopped off, the valve covers were a dead give away. Knew several AMC mechanics at the time of the switch from the GM to their own engine. guess that there were so many issues with the GM 2.5 in not being reliable and a very weak bottom end that AMC built this engine out of desperation. The AMC engine was in their eyes FAR SUPERIOR in durability and low end grunt. About the only complaint that they had is if you overheated them you could crack #4 piston, if you fixed it soon no problem if you ignored the ticking you usually put a rod thru the block when the piston finaly said "I QUIT". The old AMC 4.0 engine was reliable and powerful, the 2.5 for it's size was powerful and reliable as the 4.0. Now the GM Iron Duke was known to become a bunch of small parts and oil on the ground if you pushed them.
What about ARP main studs, rod bolts and possibly head studs for the turbo build? Old bolts, built top end+boost doesn't seem too appealing. Idk if he's going for that 15-20lb of boost mark to really call for a copper head gasket but I'd still run head studs if I could get them
Watching you talk about turbos reminds me of Tom Selleck in the ending scene of Quigley Down Under. As he crouches next to the villain he just shot in a dual, "I never said couldn't shoot a pistol, I said I didn't like them".
Sounds like a good start 318 valves
Plan Z!!
Seriously!
I remember Turbo Tune building Grand Nationals in 80s. Think there was even a cover on hot rod or car craft.
If you want to ever add a turbo to a donated Japanese car I'd suggest an old Datsun 240-280-Z because there is room for plumbing under the hood , and they are light cars, + they are straight 6 's !
When the cars illustrated magazine came out I bought it or was a subscriber already. I still have that article today. I remember the picture of the scoreboard. It said something like 1385. If you don’t believe us cancel your subscription
Uncle Tony Power Nation made a turbo charged slant six with no money limit made like 400hp I think 500torque. It the average person doesn’t have that money. I like your idea do it for less money decent results. That’s cool
The turbo six will be a fun build. Maybe build it to honor the passing of Jim who also had a turbo six project. This is going to be fun.
in all honesty tony...i'm in it to see just how much abuse that 4 m b block will take.
and then there's that crank. oh my!
Please keep us updated on the Turbo Slant Build!
I was going to source out a 82-87 motor to get that lighter drivetrain, but I guess boost will compensate for the running gear weight? Plus Stronger bottom end and more available parts too!
Alot of guys have great success with turbos and blow through carbs..Billy the kids s10 from street racing channel
Tony all the big pulling trucks run alchol/meth injection at the turbo and intake. I run this setup on my 2.2 Turbo shelby, try this on the slant.
If your oil pump goes you could just overfill the oil by 2 quarts it will splash lubricate
Hey Tony, I can't wait to watch videos on the turbo slant 6 valiant from your perspective. What's happening with the miata in the background?
Great to see that this channel is about a very good , strong engine. I lived in South Africa for many years and my father had a 1972 Valiant Rustler ( pickup) and this was absolutely unbreakable, coupled with a Torqeflite 3 speed box, all being stock...eventually the body corroded away and it was junked !! Great videos !!
great drivelines....... the rest of the car just rusted away or fell apart around them in Australia
It looks as though you have a new found enthusiasm Tony. Nothing like a new project to work on that is a little out of the comfort zone. The best time to learn. Make that leap. Begin the journey and good luck.
You need to find MOPARS hyper 6 . 225 cubes , fuel injected , turboed and 275 HP , that was 1962 . Now with todays electronics it could be a lot more .
What happened to the Miata Tony? Must have missed that episode.
Mentioned it recently and many times. Nobody will run it in an autocross, and it has lost its appeal. Parting it out is the plan.
I guess the safety plywood on the firewall thats 2" from a rubber fuel line would scare most sane people away.
Back in the 1980s, I worked on a construction site that had a lift crane, like a cross between a crane and a forklift, that was powered by a turbocharged inline 6. It was not a high performance engine but it was over 20 years old and still going.
Do you remember what the manufacture of the engine? I know a long time ago, just curious. Thanks for the comment
@@bannedbycommieyoutube5time920 I'm sure it as a Chrysler from the late 60s but beyond that I don't know.
@@DoktorJeep cool, so a slant (also an inline as you described, I was just curious). Tough, unique motor.
A friend of mine and I helped him, put a tornado 455 in the back of a bettle, nothing but motor .lol ... bad thing is couldn't get it to stop with out modifications and that's where we stopped...... Porsche brakes weren't enough.... to all that work just to tear it as ll down , subframe and all ...

Great video, as always!
a turbocharged Mopar leaning tower of power...what's not to love?🙌
#TurboScamp...you do you brother mayne
I know someone in Ohio that went down that turbo rabbit hole and went threw a few of those engines with a megasquirt. He was racing a 1/2 ton 80s or 90s Ram. I'm sure he has allot of info for you if your interested?
If i drove a few hours to stop by your shop, could you teach me how to a better tune up on my truck?
A dry-sump oiling system on a slant six is interesting does anyone have any information on that?
Through Stangnet, Ford Six and Four Eyed Pride, I've seen some great cars become Piles with Bad Electronics. A good set up is the stock off the shelf bigger V8 parts that fit on the Slant. I helped a true friend on StangNet, FSP, and FEP, but I made a big mistake in the past with advice to a guy who did the Turbo 250 Fairmont. He used a 10.25 : 1 compression, but it worked great with a Big Borg Warner Turbo and he used 62-1 crank triggered EDIS 6 and MegaSquirt. Only mistake, was not high porting the Aussie cross flow 175 CFM head, and not going more radical on the cam lobe centers So Untendered advice is Unasked for, and Unhelpful, but Hi Compression, Hi Flow head with boost retard and rising rate fuel pressure to counteract the boost growth, and a nice 4bbl intake, and the early block and crank....oooh, it'll be Good. Nice to see you getting into Boosting it without I.T. again! By the way, if you ever want to go MegaJolt Ignition and just keep the Stu B 4 bbl, I know just the guy.
Uncle Tony- you already did something with an import. You put a slant six into the Miata. I would think that counts.
I'd bet the "import" miata was wholly manufactured in the USA.
@@rahowherox1177 Every first gen miata was made in Hiroshima.
A lot of NA guys don’t go that much for boost because they often enjoy the work involved in making an NA package that really runs good. With boost you can make a bunch of power without having to worry about how well the heads/intake flows or what cam is in it. Sure, there’s more power in everything being well matched and optimized. But, boost really makes up for a lot of you aren’t chasing everything you can get with a certain setup.
The later slant sixes have less parasitic losses would make sense. Th a t and the 727 & 904s getting lockup for 3rd gear meant that they were quite fuel efficient, when the leanburn is working. My brother is getting about 25 from my estimates in a longbed 1985 d150.
Great job on the vlog-style filming. Well done.
I've got a set of oversized intake valves that have been on my shelf for the last 15 years plus an 1979 uncut 4104362 (stock valve)head with the bowls already ported (by me, not a professional but am a machinist and not my first porting attempt), runners untouched, with no slant to put it on, that can be had.
Just saying Uncle....
Uncle Tony would you like to help me do a subaru WRX build? These are by far some of the funnest cars I’ve every driven and owned! I love flying through the dirt and snow in them. they are really fun!
I’d love to see you with a 12 valve Cummins diesel, they’re so much fun and so much different plus tons of power highly recommend!
I remember back in the late 90's when the internet was becoming popular, a website dedicated to slant sixes and MPG enthusiasts. Most of them were turbocharged, with a small turbo, for MPG purposes and competition, not performance. If I recall, most of them were getting over 40 plus MPG.
I wonder what a six speed manual transmission would do in a turbo slant six?
Like a T56 or something with a 1:1 in 6th?
@@DarkLinkAD the T56 has 2 ODs for the last year
It would make it better for the highway
is it true that engines that are bored out too much run hot?
Maybe turbo a basic 318 and than step by step add a 4bbl , headers , etc Gradually see the power increase as you further modify the engine more and more.
