I’m in the process of designing and building a bolt on big block Mopar turbo kit for B/E body Mopars. We’ll post photo’s and updates right here as we go. Feel free to leave a comment below, ask questions, offer advice, tips or suggestions.
The big block Mopar turbo kit will come with turbo headers, T6 flange, intercooler and pipework. This will be a single turbo setup. You will need to add your own turbo, as not all turbos and engine combinations are the same. There will be provisions to add your own waste gate and pressure relief valve on the cold intake side, as well as provisions on the turbo manifold to add oxygen sensors, if you want to run EFI.
We’ll discuss why I’ve left this option open for you to decide as we go along.
The test mule is my own 1968 Dodge Coronet, with a 440, Edelbrock heads, Purpleshaft cam, M1 intake, stock bottom end, Mopar ignition with a carburettor.
An air to air intercooler will be easily installed between the radiator support and the grille. It will fit between the radiator support and grille bracket, which also houses the hood latch. There will be no need to remove either and the intercooler will not block the radiator entirely, ensuring fresh air can still pass through the radiator.
At the moment I’m looking to make an intercooler as part of the package. I have the design already, now I’m in the process of sourcing intercooler cores and end tanks within New Zealand. My research shows the traditional full front mount isn’t necessary and restricts air flow to the radiator, which can lead to overheating the engine.
More photos and info to come. In the meantime be sure to check out the Mopar 440 turbo kit vs supercharger article and video, along with different big block Mopar turbo kit setups that readers have sent in.
Update: 21/12/2024 – Big Block Mopar Turbo Kit For Sale
It’s been a long while since my last post on this project. Life has kinda gotten in the way lol. I’ve sourced an intercooler (not within New Zealand though),. The core measures 600mm x 300mm x 112mm thick. This will just fit between the grill and radiator support. It will be mounted low in the front, most likely flush with the engine cross member. This will allow plenty of air to still flow to the radiator keeping engine temps normal. The intercooler has proven to flow enough air for up to 1100+ hp with a 2 to 3lb pressure drop, so very efficient for street use. More pics to come once the intercooler is set in place for mock up.
In the meantime I have decided to build a kit that can be used with either stock exhaust manifolds or regular headers. I’ll post progess pics at a later date. Did I mention that the big block Mopar turbo kit will be for sale?! It will be a true bolt on kit for B/E body Mopars at this stage. Other options will be available for small block Mopar engines as well as the Gen 3 Hemi. Let me know what you need, just leave a comment below.
The plan is to make a start in early 2025, so stay tuned!! Here’s a couple of photos of the turbo resting on the battery tray. I’ll relocate the battery to the trunk. Battery relocation will be part of the kit as well.
Big Block Mopar 440 Intercooler
I now have an intercooler for my big block Mopar turbo kit. The core size is 300mm x 600mm, it’s 100mm thick. The intercooler supplier has seen 1100+hp flowed through the intercooler on many customer cars.

I’m interested in forced induction options for a 440 engine I’m planning for my 1961 Fury. The major challenge on this oddball 1st Gen torsion bar chassis (similar to C-Body) is snaking any kind of exhaust system around the steering gear, master cylinder, and torsion bars. I’ll be using an automatic transmission for street/strip use so a single turbo with a decent EFI should be fine for street drivability. Driver’s side exhaust routing is almost not worth considering with so many obstacles but a single turbo exhaust routing on the passenger side is wide open. Please provide any information or updates on your project. Thank you. John Serkaian Novi Michigan 248-510-8410 serkaian@yahoo.com
Hi John thanks for your question. This sounds like a very cool project for sure! I can definitely see how you’d be challenged for space and fitment. The pre-1966 cars are quite narrow between the fenders, so this would mean a totally different approach. There are a couple of options I can think of. If you could mount the turbo in the passenger side of the engine bay, in front of the engine, you could maybe use the stock exhaust manifolds, or tri Y headers. Routing the single exhaust from the drivers side either in front of the engine, down low, or underneath the engine or the front part of the sump, where it steps up parallel to the steering drag link, up to the turbo on the passenger side. (I hope this makes sense). This would be the easier option.
The intercooler fitment/placement would be the next thing to consider. A water to air setup would probably be best as this could be mounted in the trunk.
The second option would be to mount the turbo or two smaller turbos at the rear of the car. You’d make use of your existing exhaust to the turbo/s, then run straight pipe back to the front of the car, joining two into one then into the intake. It’s a complex setup though. I’ve linked to an article to give you an idea if you haven’t seen this setup before.
As far as my project goes, I’m still at the design process at this stage. I’m wanting to provide a simple bolt on kit with minimal changes or mods needed for an easy install. As soon as I have an update I’ll post further info right here. Good luck with your project, I’d be keen to hear how you get on with it.
If you have any further questions I’ll do my best to help.
Thanks again
