For those of you who are KAT or not ,Which Manifold would you choose if these were your choice?

log style manifold (i belive JGS)

or

Rev Hard Manifold ?


Im still debating which one has Better runner and airflow ...I like to hear some of you opinions please

I also like the Ebay SSautoChrome Manifold as well but there is no word on those yet ..Thanks in advance for your replies ..

If I had to do it again, I'd choose the JGS Tools manifold.

My RevHard took a lot of work just to make it fit. The casting tolerances are sloppy as hell. The header stud mounting holes were misaligned by 1/4" at one end, so it wouldn't even go on at first.

After fixing the holes I ended up porting it because the ports on the manifold are round, while KA ports are kinda square. That took a damn long time and was messy as hell and no fun at all. Then there was seperating the runners on the flange to prevent cracking. There's a bunch of of other material to remove from various places, too, if you want to maximize flow.

All in all, it just plain sucks. But I'll be happy when the SS Autochrome manifold is finally available, because I can just swap it in with no modifications. So, if you gotta have it now, go with JGS Tools, otherwise, wait for the SS manifold.

I didn't have any of these problems with my revhard. I've had it for nearly 2 years and no cracking/rusting through. But I do like the look on those autochrome manifolds... equal length = more power Any word on when those will come out?

Also , How many of you guys have a deciding factor on the type of material made ?

Rev hard is Cast Iron I belive ..in terms it should be more durable from the heat

JGS? im not sure what type of material this is made of ...

F-max?

SSautochrome is a very nice design but not sure what type of material it is made from ...


I am leaning more towards the SS ...but the Rev Hard seems to be around for awhile now ...I heard Nsport or XS eng Turbo kits for the 240 comes with the Rev hard?

F -max also is a log style type like the JGS ...

More feed back please? thanks for those replies as well ^^ guys..

I think material is important. I was or still don't know haven't heard from the guy in awhile about making me a custom ka-t manifold. He was going to use stainless steel which is pretty good against heat. He gave me options which were cheaper, but I didn't want to go cheap and in the long run shot myself if anything cracked on the cheap one. But the cost of his manifold was more than 1000 bucks, so I think I am going to wait and see how much the SSautochrome is.

^^ anyone else?

I don't know if you can still get a hold of this one, this is one of the best I've seen yet. It was made for Chris May's car..

http://www.executivecleancar.com/KAM...fo_and_pix.htm

I think Tom Rice still produces it.. not sure..
I wanted to get this one for my car..

another good one would be greddy's but i think those use mitsubishi turbos only.

GoKu

Ive spoke to Chris a few times and they arent in production anymore....im trying to lean from getting a custom Manifold...To let you guys know my history ...I had BYP made a custom equal length that cost me $900 for my U13 Altima KA24DE(T) ...not less than 2 month ,the car got stolen. So I was out of luck ...

Im pretty much almost done, just keeping my options open now ..thanks guys

GoKu

^^come on guys,I know theres more Turbo heads here...

95Blue240sx

i actually have a RH manifold, but im still gathering parts. i noticed that the ports are round too. i wasnt too happy when i saw that. but i got a deal on it. hopefully my install will go smooth and and everything gets aligned. but im so broke i cant buy anything for turbo setup. ALL in time, my girlfriend keeps telling me. then i say STFU gimme money!!!

anyone selling a RH manifold ?

95Blue240sx

the ss chrome looks awsome, id sell my RH to get that. depending on the material.

This place http://www.full-race.com/ makes them for the SR, and on Fresh Alloy a guy from that company said they will be looking to make some with KA flanges. They are pricey, but they are the best manifolds I've ever seen.

i've got the jgs log and i works just fine
no fitment problems
and the best part is i got to weld the flanges
exactly where i wanted them

check out the unstable hybrids manifold, its in the links section, go and look at their site under their products, it looks like a combo header/manifold, it looks part like a cast, but its welded too.

I'm using jgs tools tubular style...
log style seems to work well, and if revhard cracks cast is a lot harder to weld than regular steel....
jgs you can make fit no matter what you got, but you do have to weld it up.
revhard doesn't seem to fit very well, especially with larger turbos. master cylinder clearance is tight..

GoKu

Do you have pics of the JGS tublar style? I havent seen it before, Also I should note this manifold is going into a U13 KAT (Altima)

andrave

go to jgs, its listed there with pics of what the kit includes.

meme

if you want a log manifold i would say make your own. even if you get the jgs one you still need to grind and cut an openning for the turbo flange. if you can do that you can pretty much just weld the rest of the pipes up.
but if you are not comfortable with welding then buy a finished manifold.

here is a small write up on making the manifold. http://psijunkies.com/turbomanifold it was half tig welded and half flux core welded. i ran out of gas and was in a rush.

i've listed part numbers if you want to order the pipes from mcmaster.com . here are some more.http://psijunkies.com/240sxengine.html i no longer own this car and turbo kit

here is my next one

using flux core cause i sold my tig welder.


i can get you flanges if you need them. should be about $100 for all flanges and pipes. give or take a few bucks.

good luck..

When you mention about the tublar style ? are you talking about the JGS elbows that have 90degress and differnt bends ? compare to the log style ? I wish I had pics of the custom equal length I had before on my car , the only thing that compares is the SSautoChrome.. I guess patient is virutue, Most likely with the SS I will have to Thermal coat it and maybe do some adjustments to the flanges like the Rev Hard's

GoKu

Dude thats some real proud work that your doing, at least you can say *YOU* acutally build the manifold,its not an easy task for me because Im not experince in welding ..only mechanics , the manifold is looking great.But I couldnt imagine where to start it I was in your shoes, Thus the reason we should have threads about the types of manifold -cost-material-performance-, alot of the feedbacks here will answer alot of newbie question and rasie more opionions,

So far Rev Hard -Cast Iron ,But prone to crack $400
also is it true that Nsport and the XS engineerer use the RH can anyone confrim this?

JGS log style or tublar ...well this is basically the way you want the welding shop to do what you like IE: top mount,side mount ...so on so fourth $150 +

UH ---not really a great feedback here ...more info as we gather along the way ,altho looking at their site ,the welds looks sloppy and alot of silver spray paint $450 shipped

F-Max --well I belive they are selling them for $600?

Turbo Boss manifold -- again not much info or feedbacks yet $800

SSautochrome..AKA OBX racing , well basically Ive seen a few items from them ..welds are decent but the material is stainless steel , up for opionions $400


ECP racing (canada) is also set to release a manifold as well $600? or $800? the site is down so I cant search ,

anyways feel free to add more and feedbacks, altho I am a Hugh Nissan fantiac, My set goal is to knowledge the types of manifold , the cost. More newbies ask the same question @ the alty .net site ..also There is a few issues with the manifolds not bolting up, flanges to be seprate so he can disspate, and also the issue with the Master Brake cylinder. Altho I own a U13 (Altima) Im still running a KAT niether less..

sxse240

The ETD Racing manifold is getting very close, it seems. As far as quality goes, I'd put my money on this one.

mbmbmb23

Interesting....I'll have to keep my eyes open regarding this manifold. Some of their other work looks very nice. I don't know that I'd want to be part of the first batch (incase there are bugs to work out), but the price seem good for what you get.

Equal length runners and some heat coating process.

Jeff240sx

CONFIRMED! Unstable is no longer producing their KA manifolds, or at least not for a while. The Chris May manifold is also out of production last I heard.
If you don't like the design of the FMax, that's one thing. If you do, and want it to last, do the smart thing and ceramic coat it. HPC or JetHot both say that if the manifold cracks/rusts through they will replace the piece, provided you sent them a new one in the beginning.

thanks for the confirm Jeff240sx,

As for the F-Max and JGS , some have mixed opinions about Log style manifolds.
Some have proven much gain with the log style, But I've personally have an equal length before,altho customing is not a very cheap thing.

Im glad SSauto has made one but Since the update on the ETD manifolds, i might lean towards them ,and the price is decent. I just hope theres a way I can Mount it in a U13,

kaje36

the SR sscrome mani should be welded to my KA flange on friday. ... still got to cut off that SR flange.. and that turbo flange.... but expect some responce on this on saterday

Mark

GoKu

Great to hear kaje36 , thanks for the update.

AceInHole

Here's how far I've gone with the SS autochrome SR manifold on a KA:

the only problems are that the SR head is over an inch wider from the centerline since it has a more complex valvetrain, and the KA deck is 40mm higher. I'm extending the runners on my manifold since I'm using a T25 turbo and O2 housing, so that I don't change the positioning of the turbo. It turns out that this isn't the greatest way to save money, but it WOULD place the turbo in nearly the same place the SR's stock turbo is. This means SR intercooler kits should fit (at least using the S13 coldpipe IIRC) and SR downpipes MAY fit. I gave up and I'm having the downpipe custom made.

The option that I think may be more cost effective now, however, is to take a stock cast iron SR manifold, and combine it with a stock S14 KA manifold. A good welder should be able to do it, and both peices should be available cheap enough for the overall project to have a reasonable end cost. My SS autochrome conversion is going to end up costing me 350 just for the manifold, even though a lot of it is because we can't make a definite measure of how long to extend the mani, and so I've gotta pay for shop time to have it done so it fits right (i guess after this it'll be easier for others). The cast iron version should be a lot less as long as you can do some of the prep work....

Finally, since the difference in flanges is over an inch, it WOULD be possible to create an adaptor flange.... that bolts onto the KA head, sticks out an inch, then has an SR flange with studs in it to bolt an SR manifold to. I might see how reasonable something like that would be to make, but it wouldn't happen untill I swapped the project car to a DOHC engine, so basically not anytime soon. If someone else wants to attempt this, that'd be cool

As for Kaje's manifold... since he's using a T3 flange, he'll be able to clock the flange outward more to allow the turbo to clear the block, getting around my major headaches quite a bit easier.
