The LS Dakota truck we built has been running well for almost 2 years. We couldn't be happier with it. But, of course there is always a new project on the horizon. I don't usually write build threads, but these manifolds are so good, I thought I would post them up. They are not available for purchase, but we can make a set of LS7 manifolds into these for a customer. Here is how this cam about. LS7 manifolds flipped    Flanges cut off, closed up, and mounted in truck Drivers side  Passenger side   Drivers side looking up from underneath  See finished product in next post. |

And the turbos. These are 57 trim 0.63 A/R Chinese turbos for mock up. I will probably run them, but plan to switch to Garrett turbos after testing Money shot  Passenger side front  Passenger side rear  Drivers side front  Drivers side  Drivers side rear  |

And for questions.
I haven't fit these on the real engine, but my measurements show that this will clear the truck manifold, car manifold and injector rails.
I chose to place the turbos directly on the valve covers, with the intention of moving the coil packs. They are ugly as shit anyway.
Believe it or not, they will fit under the standard dakota hood. They are about 1 inch shorter than the LY6 engine I have with the truck cover on, so no troubles.
Twin turbos allow for smaller tubing, and a more symmetrical look. I expect that the T4 type or T3/T4 hybrid turbos will probably make about 700 RWHP no trouble. Bigger T4 ball-bearing type would probably support 1,000 RWHP if you are so inclined. They would have to be very good quality turbos though.
I plan on running 2.5 dual exhaust. I know this is small, but I am looking for about 600 RWHP from this one. I think 3 inch mandrel-bent exhaust would clear between the engine and firewall without too much trouble.
Like I said. I don't like posting build threads, but I figured these were worth it.

Holy crap dude, at the beginning I was thinking what you were going to do for a hood. Almost hard to believe the hood will close. But very cool nontheless, can't wait to see it all completed.

They seem tall, until you compare them to the motor in the truck with the intake on.  |

Yeah that does help looking at it like that.
I'm excited for this, can't wait for more updates

Anymore updates on the project? Once this is completed if you're interested I may be willing to pay you to make a copy for me. I remember you telling me over the phone your plan and I thought it would locate the turbos in a weird location but after looking at how you angled them in it looks really good. Plus should allow you to run full accessories up front. The main thin that I like about it is that you don't have to fab up a ton of pipe from flipped log style manifolds.

Nothing new right now. This was just to mock up. I am going to run aluminum 5.3 block with 243 heads, and this turbo set on my other truck. Hoping to shave some weight off of the front.
But sometimes life gets in the way.

I fully understand that. Keep us updated when you get back on it. Love the idea of the flipped LS7 manifolds.

Man that's really cool how you did that, I would love to run a turbo on the Dakota but the Hemi is very tight in the engine compartment, the Hemi's exhaust manifolds cannot be simply flipped, the bolt pattern is weird of which prevents, but I know that Stainless Works sells some Hemi block huggers that with a little cutting and welding the same thing could be accomplished and two smaller turbo's might but probably one would be easier! stainlessworks.net/index.php/products/performance-systems/headers/5-7-hemi-blockhugger-center-dump.html |
