New RB20 intake manifold

[FAST-DATSUN]

We working with a company to build a custom intake manifold for the RB20. A complete JDM style with air horns and removable Pleium. Cost would be about $850 for the complete manifold. What do you all think?????? If I can tell them we can move them they would start production based on you replies to this POST....

I don't have an RB20DET, but I think i would be great for tose who do. It come up weekly on the forum of someone with a 20 is looking for one and can't find one. As these swaps get more popular in the us there needs to be companies to make good after market parts. $850 sounds steep though. http://www.phase2motortrend.com has the Greddy ITM for the RB25DET at $670

[BoostFab]

the Greddy RB25 is already being sold aroud $650-/+ IMO $500 neighborhood would be a better price range for intake manifold. knowing how cheap material and production would be. charging for a rb20 intake manifold equal to the price of the motor is hard to swallow.

[DSMs_Suck]

IMO 850 is too steep... Most places around here (just custom speed shops in the city) quoted me usually between 500-600 to do a custom IM and get basically any TB I wanted on there.

[rbsileighty]

Is this a manifold that is a complete replacement for upper and lower sections of the stock manifold, or just a replacement for the upper? What have you done to address the forward facing/rear cyl starvation issue (tuned the runners etc)? Any idea on the CFM rating?

It sounds promising... especially if it's a high quality unit. I don't mind paying out for something that looks like I couldn't make it myself.

MY OPINION IS ASSEMBLY LINE PARTS SHOULDN'T BE THAT EXPENSIVE....WHAT MAKES IT THAT EXPENSIVE IS THE LABOR TO MACHINE THEM, REASEARCH AND DEVELOPMENT (IF THIS IS EVEN A PROCESS ON THESE).... MATERIALS STILL ARENT EXTREMELY EXPENSIVE UNLESS THE PARTS BEING USED ARE OFF THE SHELF ITEMS BEING FINE TUNED FOR THE APPLICATION. ONCE AGAIN THIS IS MY OPINION: THE MOTORS ARE ONLY A FEW HUNDRED MORE THAN THE ASKING PRICE, AND IF THERE IS NO PROVEN GAINS MEANING ITS ONLY AN ASTHETIC APPEAL OR CLEARANCE ISSUE THAN $850 REALLY IS A STEEP PRICE TO PAY. IF IT WAS AN ITB SETUP THAT WOULD ADDRESS ALOT OF THE INTAKE ISSUES AND ACTUALLY IMPROVE ON THE STOCK ENGINE.

if the design is like the rb26's intake manifold (single throttle bodies style), then i would say the price is fair, otherwise.

I paid $800 for a one-off custom FWD CA18DET custom plenum for my extremely built motor. I hope to do some captivating things with this motor, but we also have a stock plenum in my g/f's car that's very well designed. The RB's plenum leaves room for improvement, but still very effective.

Intake costs more than the motor..heh

[Yellow4g63]

$800? Thats not really alot if the product looks good and works good. And lets think about it who makes a intake manifold for the forgoten RB20? nobody lol.

WASABI GARAGE, TOP HAT, UNIQUE AUTO SPORT, AND A FEW MORE.

You can stay stock and pay nothing. Or you can think with a performance-oriented mind and realize that people do go through a great deal to create aftermarket performance parts for motors that wouldn't otherwise have anything. A company liek Greddy can afford to mass produce and pass the savings on to the consumer (you and me), if there's any. Whereas someone with a Tig and mig welder and just some idea put their time and sweet in to make a product worth spending $$$s on. There's plenty of silly little things that costs more than the motor. My intake and exhaust manifolds cost more than my motors a few times over:



Hell, these pistons cost more than the motor itself. And the standalone costs about what it would take to buy 3 CA18DET engines. So I would say to all if you're not into peformance, don't waste your money. But if you don't understand the game, don't knock the aftermarket workmanship and costs until you've taken into consideration all the variables involved with these parts.

WELL SAID DEE!

I DON'T THINK ALOT OF PEOPLE REALISE THAT MOST PERFORMANCE MODS DO COST MORE THAT THE MOTOR ITSELF BUT LIKE I SAID IF THERE IS NO PERFORMANCE BENFIT TO TE PRODUCT AND ITS ONLY FOR ASTHETIC APPEARANCE OR CLEARANCE THEN THAT COST MIGHT BE A HIGH PRICE TO PAY, WELL ATLEAST IN MY LITTLE CORNER OF THE WORLD.

[goofynick6]

Hey, I was just making a joke..as you can see by my sig I've got many items that cost a lot more than the engine did..

[boost_boy]

It's cool Nick. I've dumped so much money into my desire to go faster and faster, that I can be listed as an addict and I need help:D . If you're doing for the "bling-bling" look, when you get smoked it's even more embarrassing. I think your stock manifolds are good for the most part.

[mugen2nismo]

i have a new'b kinda question... why do you want a new or custom IM??? im planin on doin a rb25 swap in either an s13 or 14 and i was just curious why. is it because of clearance issues or is it for HP reasons? thnaks

[FAST-DATSUN]

The cost of producing a custom replacement manifold is very high and selling 1000 unit would just brake even with cost of set up and proto typing at the $850 level. What I seeing is there not enough intrest to even brake even on it, is that right?????????????????????????????????????????TOP hat makes a upper half only and I have never seen any for the others except Wasabi. Post pic if they really make one!!!!!

[Sil240]

Fast-datsun Do you have any details??Is it a full ITM or just a upper?Does it have all the vacuum and coolant ports?Also it might be a stupid question, but....What is "JDM style"?

Personally I wouldn't pay $850 for a intake manifoldUnless i saw some Dyno graphs and also A/F % for each cylinder. Not that i really know what Im talking about but RBSILEIGHTY brought up a good point

Also about the ITM price Vs the Motor priceIts irrelevant because how much you bought the motor for is a seperate issueThe manifold cost should be based upon material cost, and labor and then mark-up.Hopefully they won't go too crazy with the mark-up

[PROJECTRB240SX]

I'VE POSTED PICS OF ALL THREE THAT I MENTIONED BEFORE..... LIKE I SAID THE THING THAT BRINGS THE COST UP IS R&D. WHICH IT LOOKS LIKE YOU GUYS ARE DOING ALOT OF!

IF YOUR SHOOTING FOR 1000 MANIFOLDS YOU MAY WANT TO LOOK FOR SOME OVERSEAS ADVERTISING, BECAUSE WE DON'T EVEN HAVE 1000 SWAPS DONE HERE IN THE US.

Hate to say it, but I couldn't agree more. There just aretn't that many rb20 swaps in the states to even break even.

[goofynick6]

I built a custom manifold to make the fmic piping easier and more direct, and also so I could mount a larger mustang throttlebody. I might also gain some power from it

Nick

[Sil240]

Hey goofynick do you have any picks of your mani??

[FAST-DATSUN]

JDM style it look similar to the Hand made RB26 intakes, but is cast No cooling ports, all vac ports, individual stacks for each cylinder and removable pletum cover. Look like a dead subject although there are a lot of dealers sell allthe RB20 motor. they can get.Sorry, Will track to see if the intrest comes up....

[Yellow4g63]

WASABI GARAGE, TOP HAT, UNIQUE AUTO SPORT, AND A FEW MORE.

I ment to say is a good manifold. The Top Hat manifold dosen't even look like there will be any gains at all. The Wasabi I have but it's very rough. The only good thing going for that one is the velocity stacks that are inside and the shape of the plenuim. Mine used the lower stock flang that bolted to the head. Maybe after I get mine cleaned up it will be a good manifold. Unique's is a style just like the wasabi's, they used the stock flange.

Well said, I know for a fact the exhaust manifold I'm going to get made for my car is goin to cost prob more than $800 close to $1k.
