Next best equal length?

[slipnfall]

Hi folks, It seems IAP's equal-length DE mani is about the best there is right now in terms of quality. However their recent price change shot that mani way out of my price range... So what's the next best, for around $550? I would love to have an equal-length, mainly due to reliability. Log-style mani's have higher concentrated temperates at specific ports(IIRC), whereas equal-lengths', have equal heat distribution(or at least, better than a log).

Thanks,Slip

[DRIFTEADOR]

have you considered a cast manifold? not quite an equal length but better than a log for a similar price

[slipnfall]

I thought that a cast mani was still considered a log-type? Cast is just the construction method, log is the style. Is the revhard still the best cast for the money?

[DRIFTEADOR]

a log manifold is literally a log with flanges, like jgs's. casted manifolds at least have runners ending in a "collector", they're just not of equal length, like most tubular.

i have a bd mani and dp for sale interested. 450.00 [email protected]

for got to add, cast is the type of metal usedI i dont think u can reweld if cast breaks). the tubular design is made w stainless etc. look at a revhard mani for a cast and look at a bd mani or iap mani for tubular.

[slipnfall]

Ah I see. Well that sounds like the best option for me right now then.

Thanks for the response.PS-email me about the parts you have for sale: I'm in NM, and am always looking for stuff.

cast is the process used (melted into mold vs. rolled material/welded). cast can be stainless too. as a matter of fact i think the linked manifold may be ss as it'd be pointless to have it polished otherwise. and yes, cast can be rewelded if it cracks, and is less likely to crack in the first place.

[Structure240sx]

i have a revhard and it has never given me a problem. the only time they ever crack is when they arent prepped for heat expansion.

really the best manifolds in quailty are full-race, peak boost, and ground zero.

ground zero you can get the cheapest for around $700-800

equal lenght manifolds benefit is the extra power that is usually made with a quality manifold from the better flow. generally spool time is increased by a few hundred rpms since the manifold flows so much better there is less velocity to get the turbo going. although a few hundred rpms isnt very noticable and definitly worth the extra power that can be made.

log can still make plenty of power but it will take less boost, which is less stress, to make the same power off a quality equal lenght manifold. this has been proven many times.

theres more than just equal lenght when talking about the manifolds. its more about like i mentioned. what you notice about the full-race, peak boost, and ground zero manifolds is that the runners are very fat, phatka-t manifold is the same way. the IAP manifold while being equal lenght has narrower runners and there for wont flow as well for this is made up for in the price compared to the $1150 full-race manifold

I've been away from the computer for a bit and I missed whatever happenend to IAP. Whats with the price jump. New design or what? I may be forced to look for something else. I would love to support a sponsor, but sh*t at $700 im close to getting a Ground Zero as Structure mentioned. Some one fill me in....

See the thread at the top of this forum:zerothread?id=129935

"We have updated the pricing here as a result of changes in the marketplace and changes in cost factors on each kit."

I can't say I'm very happy with the first 1/2 of the statement: it sounds like they jacked the price, partly because demand was high for them. But that's just me and my pesimistic attitude. I also understand that's just one part of doing business, so I'm not going to get choked up about it. They go on to explain that they improved the surface of the flange and port matched, and possibly flow benched it. Note that the NICO member price is $649 for the mani's.

But anyways, I'm in the same boat as you: I was pushing the bank going with that manifold originally, but I surely can't afford it now. <shrug> It'll be a month or so untill I purchase one, so maybe the price will change again.

Back on topic: I can see why an equal length mani would perform better: the cylinder pulses all fall into line, to push the exhaust one at a time. Whereas the log or collector-based mani's may have flow interferance between each pulse.

So now because of this slight 'restriction'(summed up): does this mean when going with a log/collector style mani, one should choose a smaller exhaust turbine than you would with an equal-length/tubular?

[slipnfall]

BTW Anthony, did you receive my email Re: the CONSULT interface?

[Structure240sx]

yes i did, sorry i havent replied go ahead and send it ill make use of it

i would still remain with a larger housing over a smaller one to keep better flow

as far as a jump in prices, the marketplace prices are increasing. its inflation, grand parents ever tell you how gas used to be 25 cents a gallon? prices go up and people get paid more. minimum wage has gone up dramatically in the past couple years.

there was a high demand for the IAP kit because the price was so low and nice. it wouldnt make sense to increase it thus, like you mention, making people back off.

[DRIFTEADOR]

just to clear things up, collectors increase flow. heres a cutout of a real collector, (from burns stainless; regarded as one of the best exhaust companies out there)



cast manifolds dont use real collectors, hence the quotation marks around the word in my previous post. sorry for the confusion

God I SOOOO know I am going to get bitched at for doing this but......

No offense, but if I had $700 I'd just buy the IAP mani. The original intent of my post was to find the next cheapest, because I couldn't even afford that. But if the purpose was to illistrate a collector, I undestand.

Anyways I don't see any harm in cross-linking ... I see NICO thread links on KA-T.org.

That, my friend is a sexy sexy manifold . And no b*itching here, i actually forgot that you guys are having a groupbuy, thanks for the reminder.

[nissanfanatic]

Yes it is a sweet manifold. Sitting on my dresser right now awaiting some company.lol

Yeah i know it sux that the price of IAP kits went up. I was going to buy the kit today or tommorrow and then it goes up like 600 bucks. I called Marc myself and talked to him. The manifolds are much better, thicker flanges and flow alot better then any other manifold out there. If you got 550 why not save up a hundred more dollars and get a better manifold while still supporting NICO sponsers? thats what imk donin. Damn inflation

Bull****. Nobody.. nobody can say that they flow more than any other manifold out there, until they either borrow or buy every other manifold out there, and then flowbench them. I really hope that's your claim of outflowing everything.. because I'd put money on the Groundzero, peakboost, phat ka-t, or fullrace manifolds beating the pants off of the IAP - unless there was another massive redesign.-Jeff

[Tictakman]

i just ordered a phatkat one and ill let you know the difference between it and the boostdesigns one...

Your right... nobody said they flow better. From what i heard... is that compared to other manifolds such as revhard, the iap kit flows better or is quicker with the same set up... JESUS you have to watch every word you wirte on this place.. Didnt mean to down grade any onther manifold out there. By the way how much do those manifolds cost? just wondering for my perosnal knowledge. Thanks

That's not "watching every word"... It's not BSing about something just to make it sound better.

Oh, and for prices...Groundzero- $695Phat KA-T- $749Peak Boost- $899Full Race- $1149

[slipnfall]

Guys/Gals, thanks for the reponses, but let's not get into a pissing match here. It's clear [to me] that the flow comments were just relayed from the phone call conversate w/IAP. As such, they should be taken as just that: boasting from the designer/mfgr, which is to be expected with anyone carrying their own line of products. IMO the real world testing is up to us.

So I think I'm set on just a cast mani, even with all the spiffy tubulars floating around these days. I'm not looking to run over 8psi MAX, so I can't justify the extra investment.

I know many people stay away from ebay for performance parts, but what should I look for in a cast mani? The one on Ebay for the KA *look* like they're constructed very well. Should you seperate the flanges on a cast mani? What about putting a slit in the bolt holes?

Rick, You've been here long to earn the right to cross link, especially if it's a worth while link like the one you used. We need to talk my friend. I'm junking my JGS as well and upgrading. Although I had tossed around the idea of building my own, but your's is definitly a nice piece of work.

Well, i am glad someone notices I have been here a long time

Anyways, WD you can shoot me an email at [email protected] and ill give you the numbers I can be reached at.

Oh, and:
