Coming Soon-
CJ Motorsports Tubular Stainless Thick-Wall HR/VHR Turbo Manifolds

Update #1:
A preview of a completed passenger side setup.


Original Post:

While putting together the next version of my personal 370z project, many of the components from here forward will be custom built on my Z and then offered as production products. Some of the stuff might fall a little towards the wild side as this car is no longer my daily driver. However, most of the items produced will take into consideration that people might wish to apply these items to their own custom projects. We also recently acquired a mostly stock 2011 370z into the family, and will be able to use it to make sure some of the items will fit any level of 370z project.

One of the first items planned for release will be our turbo manifolds. The 370z forced induction market is already blessed with some high quality and appropriately priced options for complete turbo kits and even turn-key tuned packages. So we are taking a different approach, and one that I feel is more appropriate for a smaller and growing company.



I have always wanted a set of thick-wall stainless tubular side-mount turbo manifolds for the VQ, and now I have them. It is no wonder that they have never been produced before... fitting larger frame turbos on the side of this engine is not an easy task, and a tubular manifold by construction just demands more space than a cast manifold. So this wasn't too easy.

But the result we have here is a pair of GTX3582R's with Garrett 4" inlet T04E anti-surge compressor covers fitting with no chassis pounding or modification. A custom CJM driver-side motor mount bracket and altered heater pipe is required and will be provided. At this time it is unknown if the motor mount bracket will be required for smaller turbos, we have only test fit the one turbo size so far. It was our primary goal to make sure that enough turbo for major horsepower could be fit since we believe the customers who will be attracted to this type of product will most often be those who are chasing earth shattering record breaking power. But that isnt to say that we will not be test fitting smaller turbos for stock engine horsepower levels.

The manifolds are constructed to use Tials Stainless V-Band housings for external wastegates. The wastegate outlets are not pictured on the manifolds at this time because we are not finalized on the wastegate location just yet. Once the downpipe jigs are constructed we will finalize the wastegates.

These manifolds will be sold as a standalone product for DIY fabricators who wish to build their own turbo system or for shops that would like to fabricate a custom turbo system without having to tackle the manifolds themselves.

3" downpipes that transition to 2.5" to match your existing catback exhaust will be the next item available, followed shortly by a turbo oil and coolant line kit. A turbo/manifold/downpipe/oil&coolant line package will be put together. Then, finally, an intercooler and piping kit will be released.

I have machined custom stainless flanges for these manifolds. Within the flanges is a machined transition from the port shape to the runner diameters. This will significantly reduce the amount or necessity of hand-porting. Just a little cleanup with a drum and a real nice transition remains.





For an interesting comparison, here are the new manifold prototypes next to my old Greddy manifolds. For those wondering, even though the turbo locations appear similar, they are not compatible replacements.



One thing that is interesting is that our manifolds are still lighter weight, although its not a fair comparison there until we have our wastegate outlets on the manifolds.

While the photos shown above are the prototypes going on my own car, the first production set has begun and the runners have been slightly adjusted to further optimize flow. Right now the construction output on these will be slow and steady and picking up pace as supplies come in. I need to machine more flanges and we need more of our cast stainless collectors to come in.

This post will likely be updated as details are ironed out. Otherwise I will post up as details arrive. I will use this thread when the time comes to share the complimenting turbo system components.

Thanks for looking!!

First customer set under construction:

At least there will be an option for going TT for me that doesn't involve rebuying a kit

Dude those look sick....oh my pockets just fainted

Isamu

if I was TT'd I would be all over your production line making sweet love to your manifolds..

these are beautiful. and I wish I could have something like this for my single turbo set-up

Charles, once again, I top my hat to your workmanship .. the welding is beautiful and machining first class - well done !!!

phunk

The passenger side manifold will fit a full T04S compressor cover with no modification of anything.

If anyone wanted to, we would build/sell just a passenger side manifold and it could be used to build a custom side mount single turbo setup... you would have to construct some sort of crossover tube for the drivers side manifold, or perhaps cut up the stock drivers manifold to build a crossover tube.

Thanks, I cannot take credit for the fabrication work though. I made the flanges and contributed to the design and fixtures/jigs, but I have a guy who is a full time welder somewhere else who works here part-time that is building them.

Very nice!

Have you set a goal date for when your car and the new car to be finished?

I dont currently have any dates in mind... but my 370z was supposed to be done early this year. It just got put on the back-burner for other things. I took the time to accomplish a lot of unrelated goals and now I am back on it.

My Z will happen in phases. It will be run again on the stock engine with this turbo system and it will see the track again on the stock engine. I have a high power engine build happening in the background right now and everything about it will be released in a package after I am content with it. After playing with the stock engine a little further, then I will swap in the monster engine and see what the turbo system is really capable of.

Reads between the lines...Phunk is going to turn the boost up to the point where one, if not multiples, of three things happens - he sets the stock block whp record, he sets the stock block Z drag time record or he pops a motor
