Possible VG30DE ITBs

[TYL3R hez]

This is seriously the most intriguing concept I think I have ever stumbled upon.
This needs to be a production part for our cars! I will never swap my na for a tt as long as this dream is alive!

Post a diagram asap!
Keep the ITB's coming!!!!

I also am enjoying the insights provided by both NoLimit and Rare, because like them I am almost more intrigued by the why of things than the what, and especially why something works better than something else. Having some access to their knowledge is an awesome privilege as it seems that something very legit should come from this and we should be able to understand WHY as well.
I worked for several years as a extremely high end woodworker where we often designed/mocked/fabricated one-off stuff for some very famous people in this world, and to be able to have something of that nature made by that type of professional available to us for our cars will be VERY cool...

And your insights and inquiries are good. I am sure you have lots to offer with your experience in woodworking. These skills can be cross compatiable in other areas as well. Skills like these are getting scarce, and need to be shared.

For instance for skills that gone extinct is naval ship builders. They are shutting down forcing those in other proffesions. Many skills dated back before WWII are not being passed to the newer generations, so therefore lost. The new generation will be forced to start from square one.

So glad to have ya too.

[DCaff300ZX]

Thanks Rare...yeah, "we" are getting scarce indeed. I learned from shipbuilders when I was a young kid the right way to do things, and the why's and such of the whole thing which gives a great troubleshooting base for a lot of things outside of woodworking as well. Unfortunately none of those skills are passed on anymore or really required with CNC and other manufacturing methods, which is bad for more than the industry because problem solving was a key element of things and severely lacking in today's world.
Patternmaking and other such methods and skills come in handy often, and I may make use of that to do a rebuiding of my rear hatch area because I simply cannot find a red interior Z32 parting out to get suitable replacements, and no way I buy new.
It also gives me thoughts of what NoLimit faces as he goes about designing this item, and so it's really great to get the true inside scoop from you guys as you go about all of this!

[NolimitZ32]

I'm very glad to see the level of interest in this, I'll be leaving for the weekend and probably wont be back on here till Tuesday, in that time I'll hopefully have a little time to post some things up but I can't promise anything, I have preliminaries drawn up but have now slowed down to collect more info surrounding the subject. And as Rare said, please guys if you got any input or leading questions throw em up here, something you ask may not have even crossed my mind and will help me.

Thanks Guys

Anton, I ran across a thread in the RB section that might be of some interest to you. The guy took the RB26 ITB's and cut his RB20 IM to accept the ITB's. It required a little bit of fab work and I dont know if that would fit in line with what you want to do with your ITB setup. I was thinking maybe if the runners are spaced correctly you could cut them down and get the RB26 ITB's to mate up like he did and then have a bolt on intake that would end up being in about the same location as where the original upper to lower intake mount position was. Then you could put your airbox/metering system on top of that and make the system clean and simple.

The thread can be found here: my-rb20-w-rb26-itb-s-thread-t423637.html

...and another link from the same thread with a runner length calculator and conversation about the harmonics you'll be dealing with:

There was a lot of good information spread around in the thread as well, worth a read!

[300ZXttZMAN]

Any update NoLimit??

[Ace2cool]

He said he was gonna be gone till Tuesday..... We shall patiently wait.......

[legion]

He is currently drunk on Lake Travis I believe...that's what his Facebook says anyways lmao.

Saw that one the other day. ITB with water meth foggers. Ridiculous.

[DCaff300ZX]

^^^...and adaptive advance control, all for NA?
I sure hope we have someone loving the VG30DE who goes to town on it like what they discuss with that BMW, it would just be ridiculous and in a GOOD way...

[NolimitZ32]

I promised you guys a little teaser, so here it is, It is indeed very little but should give you an idea. The top is a cutaway for anyone not used to looking at blueprints. And yes I was on Lake Travis though not drunk, in fact its sad to say I didn't consume a drop of alcohol on July 3rd (the day in question) until very late in the night though the plan was to party like its 1999.

[z32pilot62]

Definitely seems to be a simple design you have going, the only thing that I think you will have an issue with is how abrupt of a change in direction the air going through the ITB's into the lower intake will have. It wont be the most ideal for keeping the turbulence down in the intake so close to the valves. Would there be any way to machine the intake down so that you could align the ITB's with the lower intake but still be able to utilize the factory bolt holes and keep the throttle plates on the same plane so you can use one throttle rod? Just something to think about

[NolimitZ32]

This one of many ideas I've drawn up and I know what you mean as far as turbulence is concerned so we'll see where this goes (gotta get together with some of my engineer friends and utilize their knowledge and extensive software library), I'm developing multiple designs simultaneously so it is TBD which one will be the final. My main concern other than performance and usability off course, is the production cost, I could easily design/make something resembling the Escort setup but it would cost me a lot of money and would therefore transfer into a pricier product for you guys (if this goes on sale, no promises) so yes pilot I understand what you are saying but ATM this is all i'm willing to show you guys

[raremotive]

Do I spy idle adapters at each runner?

Second let me know what CFD software your friends use. I was taught to use gambit.

[NolimitZ32]

You do spy exactly that, gotta have live vacuum for IAC/AAC and all the vacuum driven components like Brake booster, BOV (because this setup would technically work on a FI application) etc...

I'll let you know when I talk to em.

[bug man nrg]

I have had a good look at what is going on here with the ITB thing and if i can help with the info this i will

[TYL3R hez]

If i can make 280+ on basic bolts on's like this I would be so happy!!!!

More inspiration...

Not quite ITB, but it's the plenum setup that can be inspiring.


Yes, it's in a 300zx. Note the two turbos, in the battery tray location and opposite.

[NolimitZ32]

Holy jeebuz that's beautiful. Inspiration Ingested.

[300ZXttZMAN]

That is awesome! Rare is there a pic of that Z finished???

[raremotive]

That is awesome! Rare is there a pic of that Z finished???

It's the Unique Auto Sports 300zx

[300ZXttZMAN]

Holly crap, look at all the relocations!!!

[DCaff300ZX]

Seriously impressive, never seen a turbo setup quite like that before...

[DCaff300ZX]

Any news/updates/fun stuff to look at?

[NolimitZ32]

I've had a ton of stuff hanging over me, I should've waited to start this till after the summer, hopefully I'll be selling my Subaru soon and moving to a new position in the company. This along with a few other things should free up my time to finish this. Ive got most of the design worked out but haven't had time to run all of the flow sims and talk to the CNC shop. Believe me as soon as I have something worth showing it will be up.

[HerbieCongram53]

So 5 years later.... Anything done?
