4.0 ohv turbo hotsides

[mp3deviant721]

How much would this simplify a turbo installation for a learning technician like me? I would have some one who is qualified to help me tune it but as for the installation, would it make it easier?

its cool i stumbled upon this thread...hopefully something becomes of it!

I have came up with a Very simple and Very affordable solution for the 4.0. I worked on the manifold tonight, tomorrow I will tack it up. There will be some testing ahead but I'm on top of this project.

So meaning, I as technician in training with know how and not alot of experience could put the system together myself?

This is the manifold I'm building. If it works well it will be a simple way to turbocharge a 4.0 ohv. It places the turbo on the passenger side. Bank 2 manifold will remain in its origianl position. The original Y pipe can be modified into a U pipe to route the exhaust from Bank 2 into the collector of Bank ones manifold as seen above. The downpipe will of course be able to slide back down to the stock or aftermarket exhaust. I will be doing tests to make sure the manifold will hold up. I will also be doing test such as back pressure.... The setup may be an issue for AC and there may be modification necessary to keep AC.

any updates on the project?? i was thinkin bout doin it

I would say the DSM flange would be a better option. There are tuebos ranging from small caret t25s to larger pure race turbos for that flange. Others then that what is the thickness of the metal you ate using. I have personally seen a thin metal manifold....melt.

Does anyone know if the 4.0 and 3.0 manifolds are the same...maybe atleast the same bolt pattern...cause if they were, couldnt you possible just grab a manifold off a taurus that already points pretty much straight down and invert it so it points straight up to keep from hacking up manifold.

My problem with hacking up a manifold and welding to it, is that with the two different materials, comes two different expansion and contraction ratios and the manifolds would end up cracking around the welds.

how much would you be asking for this kit? and what exactly would it include

This is a pretty cool build but it's also been a year since the O.P. posted. Hopefully he's still around.

I'd be willing to bet its because he Totally fubared it.
There are so many other options more viable and less limiting then what he did / tried to do here it isn't funny. What is funny is he tried to make this POS and sell not only the idea to the posters but the product as well.

BAHAHAHAHAAAA..... I don't even want to BEGIN on how terrible of a manifold design that is, the flow characteristics of that would be so bad you'd be lucky if the motor made as much power after turbocharging as it did stock.

Yes, I am fully qualified and certified to say that design is absolutely insane. Essentially he is taking the y-pipe and turning it into a loop that loops one bank back into the other, and all the exhaust from both sides of the motor would flow through that one manifold. One cylinder would be a few inches away from where the exhaust exits the manifold, while other would be several feet of piping away! Talk about a good way to melt a piston, and it would be impossible to tune, if it even ran.

Just make a remote turbo setup. But if you have to ask, and I have to explain it, then you really, really should get someone to help you do it in person who knows what they are doing, but it isn't hard. I've built a turbo mustang with a friend in under 4 hours before, and it was reliably daily driven until he purposefully blew it up to make room for the 331 he built.

It's really not that bad, with the whole exhaust under pressure it really doesn't matter that much, it's common to route all of the exhaust though 1 manifold in turbo applications, granted they are usually custom logs that are bigger than the stocker, in this application it's not a big deal.

While not a ghetto setup like what the OP wants to sell, that still makes me cringe. Think of how the differences in flow will be across all the cylinders. Ideally, each cylinder should be the same "distance" from the turbo, taking bends into account.

Again, not really nessesary. The whole pre-turbo exhuast system is under pressure, you're not relying on scavenging when you've got 10-20+PSI drive pressure.
