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:

very sexy.

well done Phunk! :tiphat:

:drool:Major League!!

those are sexy as f

Glad there some options in the market now!!

Too beautiful.. Must resist..

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

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

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 !!!

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:driving:

Still have trap speed record and manual trans ET record, by accident :) The stock engine power record will have to beat me by a lot more than 3-4hp to hold me back. We all just stop where we do because of existing records. We can all just go back and forth forever on it really.

But ya, I am going to push it quite a bit further than I did before. I also have some better slicks and skinnies this time thanks to being a Mustang owner for a year LOL

Good **** Charles,

I'll be looking to upgrade in the future on my VQ35HR so this certainly has my attention. Be interested on how your GTX35's spool! I'm looking to eventually have a path upgrade where turbo's won't be my limit like they are now on my GTM TT kit (stg2). I'm looking to switch to external waste gates as well away from Turbosmart actuators.

Is the 35HR and 37VHR pretty similar for your TT setup? I'm not going to be able to be a guinea pig anytime soon as I'm still having the Haltech tuning tackled to be solid before I bother upgrading to bigger turbo's.

If your car is going to be setup for those big turbo's be easy to just mimic. Be nice if you do offer some of those additional parts like downpipe plumbing for external wastegates if you do go that route.

:yum:Man !!

Charles,

Have you thought of flow testing the design? this could help determine their max rating for those doing big builds.

Sick!

Honestly hasnt even crossed my mind. There is no such thing as a power rating for an exhaust manifold. The engine feeding it and the turbos behind it far outweigh the design of the manifold itself when there are no obvious or questionable bottleneck areas or size restrictions. I already know without any flow testing that these manifolds will support more power than any turbos that are likely to fit on the side of the engine without cutting into the chassis. Unless you are talking about over 1400 rwhp (where we might step up runner diameter), Im not sure there is much conversation to have about a limitation.

These manifolds have been test fit to the HR and VHR heads. But they have not been test fit to a Z33 chassis yet. Most likely, it fits just fine. But we wont know for certain until somebody tries it!

Outstanding R&D! Intake manifold for high PSI turbo builds next?

Thanks! That probably wont be the next thing released, but it's something that will be getting done.

Nice! Keep up the good work. It's nice to see some quality parts development for the VQ.

Make some manifolds for the BP kit ;)

ooo boy!!!!! say good bye to my greddy manifolds

You boost guys have all the fun with new parts coming out.NA is a lonely world

I am not sure if new manifolds will perform much better than the stock ones in that application. The stock manifolds are pretty decent!

These are not direct replacements, although we have talked about using the same overall design to try and make a set for someone Greddy to try out. I need to check with someone else that was already working on that to see if they are going to proceed with that project.

We just got a 2011 370z in the family to start our NA project but I dont know if we are going to go very crazy with it. First we have some catching up to do anyway.

Cheers, i will keeping an eye out for the build. I just want something to complement the jwt cams when they come out with an more aggressive version

Oh boy. Here we go Charles! Might have to finally visit you and go over some ideas! I'll have to get there before snow hits the ground though lmao.

and CJM does it again!!!

You are killing me Charles! I just about have what I need saved to get your fuel system and road rage setup. Now I need to save for turbo manifolds and intake manifold too? I may as well just start sending you money up front, lol!

Those are some sexy pieces of metal.

Sub'd.

I was going to modify the stock headers into turbo headers but this option looks way better. I'm really interested in purchasing.

Progress has continued. I should have more pictures to share early next week showing the entirely completed passenger side with wastegate and downpipe which has turned out so gorgeous.

There is a gt28 turbo on the way here, and after it gets here we can finish up the driver side stuff. I want to see if the smaller gt28 will need the custom motor mount bracket also, or if it's just the really large turbos.

We are already building a set of manifolds and down pipes for the customer who is lending the gt28 for test fitting.

Pricing is pretty much set on the manifolds, I just want both sides 100% done before I post it in case something pops up... Also I want to have pricing on the water pipe and motor mount bracket so people can figure out total costs.

Anyone who is looking for a set asap is welcome to PM me and we can talk price and time frame. Otherwise I expect these manifolds and downpipes to be available for typical ordering on the website in 4-6 weeks.

I'm super excited to get these behind us and then start building this intercooler I have designed in my head. I'm trying to make it cool enough that people already rocking an expensive kick *** complete turbo kit on their car are tempted to buy mine as an upgrade. Hopefully what I have in mind will work out.

This is sweet. I just saw and read this. Was building the manifolds a pain in the butt? I'm asking cause I've tackled a tubular manifold design earlier, and it's been a difficult journey but it's all coming together.

Keep up the awesome work man!

Oh here is mine if you want to see.
