finally able to get my turbo 318 back together after bending a valve. I did all the fuel leak checks and am ready to put oil in it and fire it up when...oil filter is too long and interferes with the T-bars. Kids woke up so we picked up a new filter. The long one was for the truck. I’ll fire it up tonight.

Still need to relocate the crankcase vents to the outside, maybe to the outer fender. E85 blowby is nauseating.

Right on! How much boost? Care to share some video some video of driving it when you get it done if your able?
 
I’ve ran 10lbs corrected to sea level. Want to detune to 8. When the quirks are gone and the tune is nice I’ll upload some videos
 
I hear ya! Very neat and well done set up. I've seen some turbo engine bays that are absolutely cluttered..lol
I have a 408 Vortech Ti trim intercooled supercharged 03 reg cab Ram. Running in between 8-9psi. Thought about turboing it but the fab work was over my head. Wished I knew how to weld. Don't know anyone in my area that could do such work was another reason. Might turbo my 67 cuda with 360 later in life.
Did you complete your own fab work?

I like how you're using a Turbonetics turbo I don't see those very often. It's nice you can find E-85 too, almost all the gas stations around here stopped selling it.

Some day I will do a turbo build but I don't think it will be for my Duster, I think a '70s smogger B-body would be my choice. Too many other big ideas for the Duster (G3 Hemi swap and no I won't turbo that LOL).

Thanks, the military aircraft world instills cleanliness. I did my own fab work. I couldn’t weld, either. So I took some classes with the GI Bill and got an associates in welding and multiple certificates as well. The radiator reservoir, the fan shroud, the alternator bracket, and the windshield washer tank were graded projects. Welded the exhaust all up with an old scratch-start tig at home - gave me hell but it worked out well. Wasted a lot of argon with the pipe purging and all. All stainless. Would have went mild steel but the weight was a concern with iron heads and all. I would have inconel headers but didn’t have enough scrap in the right size, plus there is no such thing as an inconel header flange.

The turbonetics is nicely sized, 62 mm compressor, .84 a/r. Full boost by 2800 rpm or so. My brother in law says they use a turbonetics on their army drones with common failures. Not sure why. Micky mouse rebuilds and balance jobs I’d suppose.

I’ve heard the gen 3s like to lose valve seats on high boost but I’ve seen a supercharged gen 3 go 10s of thousands of miles without issue. A smogger big block is almost made for boost.

I'd probably do a turbo 318 for the gas mileage, I want a nice bigger cruiser Mopar with some power but driving a big block regularly would kill me on fuel costs. Kind of ironic though the BBM has more head bolts and can handle more boost.

A boosted 361 BB would be interesting I wonder what kind of gas mileage those get...

Fuel cost is real - especially premium and up. The e85 works out nice. Downside is the smell. Apparently there are additives to make it smell different, can you believe that!? Probably some fruity ****. I’d buy popcorn scent if they sell it - that would be fun. Can’t beat the smell of race fuel, though. I break even with cost compared to regular gasoline.

Fuel mileage with a boosted engine is better when off-boost compared to a big cam. My cam is a mild 218/218 on a 115 lsa. It’s nice that you can simply demand more power with a turbo and it provides. The best thing about it (and I rarely hear talk of it) is the turbos love for numerically lower gearing - highway gears. It needs something heavy to move and load up on. I have 3.55s but if I came across 3.23s or lower, I’d take it. And cruising is much more pleasurable this way. One of the main factors in my turbo decision was it can cruise with high gears. And high altitude is such a power vampire that I couldn’t imagine building a 408 that acts like a 318.

Started up nicely, guys. Tuned idle fueling and spark. Runs nice. Too dark for a vid and too late to go past idle. Drowned out the neighbors ghetto blaster so that was a plus.

Sounds like the proper way to learn how to weld...lol I'm going to purchase a welder and have at it I suppose. Where I work there is a lot of welding building cabs for Caterpillar bulldozer, mini hydraulic excavator, and small wheel loaders. I install the glass in the cabs so no welding for me. Might talk to some of my buds on teaching me.
Ryan Hogan (tuner guy at Flying Ryan Performance) had a turbo system fabbed up using headers on a 408. The cost was right at 5K.... he is buds with the shop owner as well. Kind of blew him back when he got the bill...lol
So there is a lot of fab work using headers. Ryan said it was done right but was expensive.

It's hard to believe but I get better gas mileage out of my SC'd 408 than I did with the stock 5.9 mag. It's all in the tune. If I could keep my foot out of it then the gas mileage would go up even more.
The 5.9 was really bad on gas.

I hear ya....e85 stinks, but it sure works well. I've actually grown to not hate the smell...still not good though.
 
For the E85, can you not fab up a chambered catch can, and route the crankcase vents back into the intake?
this is a sharp looking set-up, and kudos for cashing in the GI Bill and getting after it. In the name of being meticulous, order yourself some of this in the appropriate sizes...

Unless you are/were sheet metal, then it's amazing that you haven't actually welded your eye out.
 
I see the DIY auto tune relay board. Are you using megasquirt and if so which version? I just completed my megasquirt 1.

Whew! 5k in pipes! Welding is a lucrative industry. I charge $60 an hour to weld odd jobs. It took a lot of time to build my exhaust. About a year. Working full time, school full time is a drain. Luckily my instructors were awesome and let me use their equipment on my own stuff.

ya know, that’s not a bad idea on the vents. I’d have to hook it up to the atmospheric side of course, it’s all silicone and filter element up front. Does anyone know where to get a bulkhead fitting that fits the circumference of a pipe?

I need to loom the wires, lol. Still adding some wiring and fixing the originals. Did you know the CV-22 engine has ribbon wiring instead of bundles? It keeps the wires cooler. Pretty neat. Balls and tits of steel those men and women who fly them.

Ya know, we don’t use F4 tape that much for repairs. It’s all rtv silicone. I’m a turboprop technician so I’ve destroyed my wrists and forearms lockwiring everything together. Maybe when I’m old The VA will 3D print me some new wrists.

It is from DIY, works very well. I’m using MS2 v3.57 - only to run mpfi. Otherwise I would have used Ms1

That's a really clean lookin build. One of the reasons I'm not crazy about turbo builds is because a LOT of guys just don't give a darn about details. Yours is very clean lookin.

Thank you, ya know I almost went sloppy with it threw on magnum exhaust manifolds or built some fugly ol’ logs but it just didn’t feel right. The turbo and intake were just too pretty. If it had the beer keg intake and a rusty old holset turbo I probably wouldn’t care about some logs either. I had a lot of time to tinker and think about the build.

...and don't get me wrong, there's a level of cool doint it "junkyard style", there really is. But I think for your build you went the right way.
 
What’s wrong with magnum manifolds??? :poke:

Nothing, actually. They’d perform better than headers. Wouldn’t warp and leak and when they’re nice and hot, retain much needed heat that would otherwise whisk away exhaust pressure the turbo would see. I have to wrap my headers and pipes to try and keep the heat in and the pressure higher. They’re just ugly lol
 
I was just teasing triple R. They work good, cheap and fit. I tried to make mine look better by sandblasting them and cast blast but it’s like putting lipstick on a pig!
 
What about pressure ratio intake to exhaust side, aren't headers better for that? I read in a David Vizard book that most home-fabbed turbo setups can't do better than 2:1 exhaust:intake which is why a low-overlap cam is usually used; the higher pressure on the exhaust side pushes the mixture back into the intake if there's too much overlap. On max-effort race setups the ratio is 1:1 so any cam can be used.

Ya know I’m not sure. I’m on the stupidity level of funneling all the exhaust into the turbo lol. But I could imagine that headers would be better overall in a pro build. You could effectively time the exhaust pulses to become sequential, flowing into the turbo. Instead of being like me and having every cylinder randomly pump exhaust into the plumbing at different times.

Dumb ol’ logs work very well tho. And many Diesel engines basically use a log type manifold. The heat retention, less prone to cracking and warping are huge benefits, not to mention the price tag.
