rb26dett intake manifold and itb's on a rb20 head

[nizmo zilvia]

yes but i have seen complete rb26 manis for under $300 even.

[avendi]

How far from Dyno testing are you?

[Chaos the Xile]

yeah can't wait to see the dyno results also add me to that list for a RB25 adaptor plate!

[Coolwhip]

I know of a complete manifold with itbs, injectors, and all, for $600 if anyone needs to source a complete rb26 intake side.

Ricky, was that YOU I saw sneaking around my sooper-secret R&D facility?

[Coolwhip]

It was I.

Was curious what you were doing with all those Honda D15 motors on engine stands.

[nizmo zilvia]

After all. The Race Wars are coming up...

I KNEWES IT! ... You should have just stopped in for a beer bro!

Zilvia,I better get back to converting my horn buttons to activate my naws!

... Now back to our regularly scheduled 26ITB's to 20/25 discussion...

[DeclareYrWar]

add me to the list for an rb20 adapter plate. very interested to hear a final asking price on this as well as the dyno results!

[neonbomb]

Chalk me up one for the plate adaptor for a 25. Please email the newest pics to [email protected] also

[Sil240]

I'm very interested in this, but like the other guys if its $500 for a adapter plate I can't participate.

But if you have the CAD file or if you have the .dsg file (CADCAM/MasterCAM i believe) I know of a place that has CNC machines. They would probably do these plates for Cheap if you had the .DSG file.

Let me know [email protected]

[nizmo zilvia]

I took CAD in school and still know how to use it. I too can create one if I had the measurements and crap. However I don't recall anyone here in town doing such work.

[omgsky]

Put me down on the RB25 list as a maybe. Depends on how much it is . I have a god father that does cnc machining.. I could maybe use that design file as well

[BoostFab]

something like that probably cost around $100 to fully cnc'ed. there's nothing much to it. the will charge a little more for the first one, since they have to get it converted into g codes, software does all that. still no way near $500 either.

[omgsky]

Then $200 or so might be a good price.. make's profit for them, keeps the price decent for us

[HPF Chrisk]

When will you be able to get us some dyno results? thats going to be the thing that makes up the 25 guys minds, i am still in either way, i want itbs lol

A voice of reason..................

[iroc07]

I agree, the materials are bought by the pound and class by machine shops ( I know how it all works because I am constantly fighting with them) and that is maybe a $20 piece of aluminum and an hour of machine time, plus another quarter hour of setup time per piece, so for $300w/harware it would be fair. I have a fastenal account so I could even get the fasteners at discount for everyone.

Brody-Let me know if you want me too, I am not trying to horn in on your deal here, I am just offering to get them cheaper and save you some hassle and time. I am at fastenal at least once a week anyway so its not a big deal.

I might be interested in one of each.So email me if you can, I would like to talk to you more about [email protected]

BTW man this is a great idea, I had the same idea a few years back, but I didnt think there was enough interest and I put it out of my mind, but it seems you came up with this at a good time. Props, more power to you, this was nicely done and you deserve boatloads of credit.

[Fearsome_tea]

Here is CJmartzk2 rb25 with an adapter. [IMG][/IMG]

[thefro526]

would this set up require a tune and a map sensor like a normal ITB setup or can you use the stock MAFS and tune?

[Sil240]

No the Stock GTR uses twin MAFS (due to the twin turbo), but you can stay with your single MAF.It would be better to get a tune, but not fully necessary though.

If it was N/A and there was no Plenum for the ITB's, then yes you would need to run a MAP sensor. Either that or 6 little MAFS on each runner.

[HPF Chrisk]

Any word on the spacers? I would really like to get the ball rolling on this cause i want to get mine installed asap. is there anything we can do to help out?

[HPF Chrisk]

Can you send me the file that is needed to produce this? I have a local machine shop that will make it for me. I am going to pm you to.

thanks

i doubt he would give a way the key source to his $ making. get some gaskets and draw it yourself.

[preston240sx]

get me a price and i should def be in !!!

yea i figured he wouldnt but its worth a try

[digzsublime]

Wow, the direction this thread has taken makes me sad.

Brody, Good work man!! I'm a big fan of the idea and execution. Personally, I wouldn't reproduce this part. I'd keep it all to myself. Especially after the way people are already whining about a price that hasn't even been set yet for a part you haven't even completed.

This isn't something he whipped out with a rotary tool in his garage. It's a specialty, low volume, niche market piece that you can not buy anywhere else. Last I checked, if you don't like the price of something, you don't have to buy it.

To all the experts who chimed in with their cost estimates, I'd love to see you get one of these made for less than 500. Now keep in mind. Part of that money would be to pay a shop to do all the R&D for proper fitment. Then, you'd get to pay a machine shop the set up fee. Buy the material, and then hope it turns out good and fits well. If not, well then you get to pay them all over again.

Sure, if you worked at a machine or fab shop that had all the equipment, and you did all of the labor yourself, it could be done cheaper. But, if you bought this hypothetical kit, you wouldn't have to do any of that.

To all the whiners. Please zip it. Let him decide if he wants to make it and let the rest of us have a shot at buying it. Then, you can buy the poor fitting knock offs on egay!

Pretty sweet! I've heard of this idea since the early days of this swap... glad to see someone actually did it!

Before selling it or taking orders... I would highly recommend completing your first setup, test it, and develop your pricing when you're very comfortable that it's a good business case as breaking even might turn out to be expensive.

Those who've been in this stuff for a long time... you don't want to turn into another Cameron (one of the early importers/swappers who promised the world and bit off A LOT more than he could chew... ended up in a lot of legal trouble)

Keep up the good work!

[BrodyGoble]

For everyone still interested, the development is nearing the end and scheduled appearance is planned at the dyno in the next couple of weeks. The adapter has been flow-benched and exceeds our initial expectations. With final testing nearing the end, we will have final numbers and a sure product to provide to the Nico community.

[Carl H]

good stuff but I feel that a full on tune will be needed to take advantage of the itb's.
