Feeler For Custom CZT Style Intake Manifolds, Roof Support Bars, & Rear Sway Bar Kits

This is a FEELER Thread only, I am trying to decide if I should take further action on some of these options, all or none. So please tell me your thoughts, interests and lets go from there. (I got permission before posting it so please do not delete it this time, let me know if I made an error or broke a rule first... I hate rewriting it lol)

1st) Custom Intake Manifolds based off the changes made by CZT with my own additions. A bulk Buy Price of around 550 for the first 5-8 Units between here and PT is what I am thinking. Before the Bulk Buy Even happens all units will be finished so there are no CZT Nightmares.
For those who do not know about it let me give you some information:
  • Single Plane Style, Mounts right in the center
  • Velocity Stacks
  • Easy Access to Rear Plugs and the back of the block
  • Uses Stock Rails and Throttle Body
  • Differences for N/A and FI (N/A will have Changes for Air Channeling where as the FI will be the same as PMO with there shown 37WHP Gain)

N/A I believe it was shown to be around 25WHP depending on Mods.

There used to be a lot of information on CZT before the incident. I will def be making sure the same problems do not come up. With the first batch we will be paying for the jig to be made after that when an order is placed it is made right away. If the Jig is not available as the shop we will be doing the work at does have hours and holidays esp during the Sand Dunes Popular times. (Not to mention he builds many other custom vehicles) We will ensure no orders are allowed at those times.

Ok here is a thread with some, there are only 2 of these manifolds in existence and until a weeks or so ago no one even knew this one existed.
ProbeTalk.com Forums
We have boosted numbers for sure:
Millenia 14psi 280whp
CZT 14psi 318whp

I am working on the N/A Information now.
It does seem there might be a loss of torque on the low end but I am looking at the Splitz Manifold (I think that's how its spelled) that there were also only a few of. However on the Top end it seems the gain was between 18whp and 23whp depending on TB Changes. However its very apparent if your going to go Higher reving (As mine is setup for) your def going to enjoy the difference as the above information was with the stock rev limit.
I will continue looking and my Manifold changes for N/A should also help but until my changes hit the Dyno (Some changes Rusty and I talked about over 2 years ago when we started thinking about doing this ourselves but he ran into a lot of outside work that was more profitable). So Again until true numbers are posted this is just searching around at what we have available.

Pics of the Manifold I currently Own and will be Modifying:




2nd) Roof Support and Brace Bar
This is pretty self Explanatory and will be easier to build however I am looking into make again 2 models.
One like mine and one that is a little stiffer for those who remove the rear seats.

Pic of my current one:



3rd) Sway Bar Setups with Adjustable Endlinks
Now this idea has been done before. I have a few options from 17mm to 22mm that I think will be easy and cheap for everyone. Around 150 for a kit size will not make more then a 30.00 difference in price.

I am also looking into making the End Links Grease-able.

So what do you guys think? I would like to know if your serious on the IM's as I am probably going to move forward with that before Christmas for a Jan. Bulk Buy if things look good.

maybe you could point me to some info...but without some decent length runners won't you see a serious drop in torque? (unless you're FI)

I will track down the old CZT Information but I def do not want this turning into a debate completely. I def agree concerns should be voiced but lets not turn it too far into a debate. (Not saying you did I am just trying to steer off the course of what sometimes happens lol, I know I have taken part in it many times)

I will search for the information Originally posted and such for those who have no information on these manifolds.

Ok Boosted specs and proof posted back up. I think those numbers alone speak volumes for the FI Guys but most know I will go SC again but for now I am staying as a High Reving N/A for atleast a year or so unless I magically make a ton of money some how in this economy lol.

I still remember these showing a big gain NA too but that was around the time of the Twin Chamber one. I am working on more information.

I'd be down for a IM, if you can find spec's(been looking for a few hours)

would these aid in a higher reving engine, say 9000/10,000rpm?

Have to ask...What disty is that?

I remember someone dynoed one like that on an NA motor and got no gain in power and lost a lot of torque. Not trying to naysay you, I am down for one if it is designed correctly to make NA power. To do that the design will need to start with long runners.

The roof bar looks wicked! I would be down for one, is there a design were it does not have to mount to the B-pillars? I remember one of CZTs designs had a bar like that. I cannot mount anything to the B-pillars due to a roll bar.

For N/A Dyno showing no improvements I would like to see that Even that SPE Place showed a lowest of 18whp and another with 23whp I believe it was. (All found pretty quick on PT)
You do seem to lose some low end torque but the links never worked for the dyno and I had to go by the talks which all seemed to say around 3200-4000 RPM's.

As for aiding in higher RPM's that is something every N/A and FI Thread I found talked about well raved about. The motor sounds completely different according to them and esp up high its smooth and really responds as well as comments of it just keeps pulling.

For those who remember the threads on Removing VRIS (Which I seem to do to all my KL's anyway) you lose some low end torque but gain HP in the upper bands and every time I did it the car was a lot more lively esp with cams all the way to red line. I can only imagine what will happen with Megasquirt, the Ported and built Heads I have and my KLZE Bottom end project with these odd cams he gave me. I will def be posting pics.

Other then that seems like we have a start but I am not sure I should invest into making this Jig for mass production. I might just make a few one off's and call it at that.

i've looked around PT and haven't seen too much info on this either. But i'll keep looking, I'm def down for one if the numbers are there..already looking for 7500-8000 with my interprep springs and cams in a ze..if this IM helps at high rpm i'll be all over it

Put me down for one. Also, if you can provide custom fuel rails to go with that, that'd be even better. Either way, I'm a definite buyer.

Do we use our original throttle body? It would appear that you could use your original injectors vs any aftermarket if you wanted right? Will this be matched for the DE or ZE head? Im guessing ZE as DE guys use that for better performance as well right?

The main thing that draws me to this is the fact that you can get to the injectors and rear so easy. My interest will depend alot on the Aussie dollar. But I am planning an engine build and this would top it off nicely. Would need more info + numbers to be convince though. As this will probably cost me $700+ if it sells for $550US the way things are going, maybe more.

Yes stock mount points for our TB's and the same for the injectors. I forgot to add that I guess.

Not sure on Aus vs US Amounts but the 550 Price is for the bulk buy only. After that its 800 most likely a pop. I might make the bulk buy less but it depends on the cost to build them.

I will also be looking for those in the Bulk Buy who are getting a cheap deal to dyno with them and post results before and after. (Another reason I will be keeping it only about 50.00 above the cost to make the first batch)

So Cross, any word on the roof bar? It possible to get one that does not bolt to the B-Pillars? Like I say I remember seeing a CZT design were the mounting points were all on the roof.

I am going to look into that but at this point I have been putting more effort into the Manifolds as the Sway bar and Roof Bars don't seem to be getting much attention. They will become my side projects until the manifold project is done.

I have been talking to Rusty and the production cycle would start in Feb. So hows that for time to get ready.

Also since I am going to do 50.00 above the cost to make (Which could turn out even less then 500) I am thinking about asking for a Dyno Deposit. The reasoning behind it is we need to get everyone who buys at this price to go to the dyno, those numbers are very important. No more then 100 which you get back the minute we get your Dyno Slip eMailed so we can show the results to the community.
How would everyone feel about that? We only started thinking about it after Rusty brought up how many times he has been promised Dyno Results and never seen them until he does it himself.

Don't overstep your bounds Cross. Asking for a dyno deposit is a good way to rip people off. It's not up to the people who buy the manifold to get the dyno numbers. It's up to the manufacturer.

Please note that this thread will be closed in a week since that will provide a long enough time to gather INTEREST in producing the manifolds. After that, you will have to get in touch with Admins. to get permission to sell on the site and take any questions to PM's.

ya, its a bit tough to shell out for something that is unproven. Furthermore, its not worth it for you to start shipping things not knowing if you're going to get any results or not. If i get a manifold that ends up shitting the bed then where does that leave me?

there has to be some legit evidence...even then i think it should be backed up by a third party. There are a lot of claims out there...and a lot of the time is complete bs or just talk with nothing to back it up.

I would love to help out but not in a way that puts either of us in an awkward position
