Thought on Turbo Manifolds

[WhiteS12+1]

I am in the process of gathering my parts for my GT28R, and was wondering if I should upgrade the manifold. I always thought thsese things crack after awhile, but after talking to a local guy about one he said that is was fine for almost two years and still going strong. I was just wanting to get you guys thoughts, recommendations, and personal experiences with these things. I know the saying goes you get what you pay for. By the way this is for a Redtop.

the saying is true.. lots of people have had success with say.. megan racing..but have you ever seen a car equipped with a HIGH end exhaust manifold? forget hks, jic, full race.. they are all over priced. look into the Tomei Expreme.. get it from C2Automotive. $599 shipped. The welds are perfect, the metal is thick, and its the most complete package ive seen. it comes with all the gaskets you need, a 2 bolt turbo inlet gasket, heat wrap, clips for the wrap..multilayer exhaust gasket, turbo inlet gasket.. and they are all OEM. so if you think about it.. the exhaust manifold from them is $450.. seperate everything else and bam.. go into the group buy or advertiser specials and look for their largus/tomei special. i have a video clip of the boost response the manifold gave, and a list of my whole power setup. the exhaust note quieted down for me, and gave a more deep sound. as far as power goes, the power gains i saw were huge.. no dyno figures, and my setup is still untuned.. but it is enough to scare me a bit :) boost response is absolutely fucken crazy.. you'll see it when u look at the video. so yea.. upgrade the exhaust manifold, make it the tomei.

how can you compare something like like a jic/silkroad/megan/hks with full race? full race manifolds are quality hands down.

to the original poster, either go cheap with something along the lines of megan or go quality with full race.

my megans fine, no problems 2+ years

[DJ_Sunrise]

i can compare them because ive seen and driven cars with all of them, including the kazama exhaust mani :) so i will say the MR is a cheap alternative, but a fuckload more likely to break. full race is great, but paying close to a grand for an exhaust manifold is rediculous. btw, on an SR.. an equal length exhaust manifold makes no additional power over even a stock piece until about 6000+ rpm. something to think about :) tomei expreme makes less power than full race/hks/jic after 6000+ rpm by a marginal amount. but nothing can compare to it because of how fast it causes the turbo to spool. my 2 cents from experience. :)

-Bart

[kensreliableb18b]

all aftermarket manifolds are prone to cracking--that includes your super duper tomei expreme. either go cheap or go baller. scared of crack manifolds you say? dont upgrade then.

[MadScientist]

I completly second the Tomei EXpreme Manifold... this is by far the most well thought out and best quality designed Manifold on the market today, and the price is very nice. EXpreme is designed to have faster spool due to the devorced exit chamber. Also it has not a single Hot Spot like all Equal length Mani's have... even if you think its to hot under the hood, it comes with thermal wrap.

Pay less and get a hell of alot more... Go Tomei.

To the original poster:
Look up the posts on FA by Geoff (sp?) from Full Race where he does manifold comparisons of his products against other manifold types. He's got dyno data with equal set ups.
Tomei looks good and could be great but I haven't seen any tests yet. DJ Sunrise, Madscientist - you guys got some info to back up Tomei? It'd be cool to see that.


Damn you Aaron.... being poor sucks.

[silverarrow27]

My thoughts, daily driven car with quick spool...go with Tomei. All out dyno queen go full race.

[Dousan_PG]

dyno queen full race?
hahahahahahahah

full race has PROVEN numbers to back up their claims and sooo many full time track cars.
tomei has...jdm branding

[WilloW]

While on vacation I had a chance to look at a Fullrace manifold and a Megan, all I got to say is that they are a world apart in quality. Fullrace.

Full Race did their test befor the Tomei was released... and I agree the Egual Length type/ Full Race would be better for larger, top end performance.

I can back this up from personal experience with my own car and old customers.

I am using the Peak Boost with gt35r and its night and day compared with log.

its rocks im using the 38mm with no issues as of now.

Nice to see your joining the big top mount crew lol aaron

[steve shadows]

you doing 50 trim ay?

i have actually used the 40 trim with pretty good sucess for response on the sr for drift setups, its all about timing and cam selection bla bla...

what ems? out of curiousty and then we can get back on topic.

BTW the exaust gas temps are kept at safer levels with equal length designs as well and typically supports faster spool times and smoother boost come on.

my friend hsa one
works fine
but u gotta buy what one can afford. and hope it doesnt crack

[CKAMC]

From what I have acually seen since I have seen both full race manifold and peak performance manifold I would still put full race at the top. The manifolds continue to be tested and have not failed at all and are currenty to my knowledge out here being used by Justin *aka bling* for drifting and no problems and infact after about 4 hours of tracking the car he pulled over for 10 minutes becuase he wanted the manifold to cool of before going for another hour/two.

brady is the local time attack guy who runs the manifold and loves it and continues to run great on his GT28Rs powered s14 that ran third at GT live when it came to phx... the only ones that kicked his ass? just come top japanese drivers with 400+ hp cars and he is only around 290rwhp.

Also its quite tough to get japanese warranties compared to a US brand that is as full race so you may put that into mind. No one else to my knowledge runs a tomei manifold so I am more than willing to try it out for us local desert rats.

Ohh yeah these manifolds see tempratures that some of the others on here may not see often but thats just because its Arizona.

[silverarrow27]

hahahahahahahah

full race = dyno queen horse power

Full race has "proven" numbers to back up their claims and sooooo many full time track cars, but most dyno sheets you'll notice compared to the other manifolds that it gives you more top end power which is good for race cars, but who's going to be using top end power on the streets??? If I find that link from months ago comparing manifolds it even agrees to what I said. Not everyone wants top end power.

My opinion again, Tomei for quicker spool on street driven cars and Full Race for dyno queens on who has the biggest d|ck. Eh, if you guys don't like my opinion...:gives: Everyone has their own brain to make their own decisions.

i got the peak boost at a steal from enjuku a while back and there is a full lifetime warranty as long as you dont use header wrap on the bad boy.

Full Race is worth the money and Peak Boost is the next best thing. I would suggest welding the inside of the runners on the PB collector but you may void the warranty.:bash:

[Dousan_PG]

by your reasoning
who needs good poewr on the streets
because street driving ill drive my truck w/ the ac on and no worries on the cops

whast the point of having a 'rad' car for the street
save it for the track? right?

dyno queens
hahaha
have you seen the some of the cars that run full race? theres no dyno queens for many of them
go read their site
get educated.

and a few local drift guys run them too. they had ran previous lower end models of manifolds (ebay spls). night and day.

but i guess poor pepole will always try and justify stuff. its like buying megan gauges. or rota wheels.
whatever

[S14DB]

http://www.jdm-option.com/eng/parts/06_02/tomei.html

[CKAMC]

ahhaha dyno queens is such a joke. I think justin isnt anymore than 375rwhp on his gt2817r and like i said earlier brady is at 290ish rwhp on the gt28rs.

[staygold24]

Id get full race if I could afford it but I thought equal length make it spool later and really help on top end. But with a tomei expreme would it make a gt2871r .86 spool up like a .64?

[Dousan_PG]

a log WILL spool faster
but you wont make as much power

a equal lenght will make more power, possibly spool later (depending on brand it varies) and such. by spool later wont be more then a couple hundred RPMS
and if ur 'racing' at 4k ur an idiot anyways hahahha

i never am really blow 5k at the track so imo, its really not an issue

btw, on the day we were filming, in NJ, we hit record high temperatures. the day before it was 115 where i was working at 90ish humidity. the day i made this video it was a bit cooler, around 110 and low 90ish humidity humidity. yea, i was only boosting around 8 psi. :gives: tonight, 70F, and low humidity i was boosting around 10 psi. needle on my boost gauge shot up instantly to 9, and made its way quickly to 10. Equal length manifolds show peak power after about 6200 rpm on SR's. many sr track cars around where i live... by ATCO and englishtown.. stay at their 7000rpm redline. id rather use tomei knowing boost is there immediately, not having to worry about being 6500rpm or higher, and still getting more power than equal length throughout my entire power band. boost builds the second i touch the gas.. even at 1000rpm. if anybody wants me to make a better quality video, i will.. ill just need to upload on AIM or watever. lookup the largus/tomei specials run by C2 auto for pictures. oh yea.. btw.. after making that run in the rediculously high weather, i popped my hood and was able to touch the exhaust manifold repeatadly without burning myself. it runs very cery cool with the wrap. very complete package as well. i guess if you really wanna be baller, spend the 1K on full race. i just hope y'all spend ALL your time about 6k rpm. :wavey: a couple of guys i know have the Full Race.. its a beutiful piece, very functional. but IMHO, Tomei is better all the way around. i wish it had a lifetime warranty, but if it cracks.. ill buy a 2nd.. and a 3rd.. but.. that wont happen.. everything on it is so fucken rediculously overbuilt, it wont happen anytime soon, especially since i have a flex pipe. :) +1 for full race, +1 for tomei.

i hate to jack the thread for a sec, but i think im being very helpful, so help me out guys.. my starter on my s14 sr is going, is there another car's starter thatll fit, such as the 200sx with the sr20de??

-Bart

[Dousan_PG]

how do u KNOW your making equal power? you got some dynos to compare? or just the butt dyno??

its not a matterof redline
its a matter of not having to shift and fall out of the powre band.

stock turbo shit you can romp on it all day
upgrade your turbo you become more aware of your powerband.

you heat wrapped your manifold? shit bad news bears.

dood stfu
haha
serious
spend 6k at redline? HAHAHAHAHA

do you READ anything like dynos and shit and people who drive with it?

my s14 sr is at 8k rpm redline. did some head work and whatnot
drifting im at least at 5500 to 7k ALWAYS. if not im bouncing off redline
full boost by 4k on a cheapie manifold (my friends w/ a larger A/R turbine)
i should be about 3800 rpm at full boost on th efull race (smaller A/r)
my buddy hit full boost with a manifold change (from cheapie to full race) and hit full boost about 200rpm sooner then the ebay spl.
thats full boost on a large turbo, about a 350rwhp motor. full boost by about 37-3800.


here's some real testing besides your butt

http://wakesports.com/full-race/index.php?act=ST&f=2&t=249&st=0

log vs tubular from full race

i already posted the link for the test enthalpy/mattback did from FA

fact is, you may have faster spool but you arent making more power.
run a equal lenght spool might be slower by about 2-300 rpm but you making a significant higher amount of power

dynos prove it.
end of story.
done deal.

[Flybert]

I'm pretty sure the tomei design is made the way it is just to meet regulations out in japan so you can keep that one smog intake valve working. They even mention that in their ad. They'll sell way more manifolds to the japanese market with this design instead of having to compete with all the chinese made ones. I don't want to say it's all jdm hype because I haven't seen a dyno, but it seems that way to me.

[ManoNegra]

Full Race vs Tomei face off... Someone make it happen.

[kensreliableb18b]

id rather use tomei knowing boost is there immediately, not having to worry about being 6500rpm or higher, and still getting more power than equal length throughout my entire power band. boost builds the second i touch the gas.. even at 1000rpm.

t28 will boost fairly quickly regardless of manifold


i guess if you really wanna be baller, spend the 1K on full race. i just hope y'all spend ALL your time about 6k rpm. :wavey:

no really, you're kidding right?

[Dousan_PG]

haha
i think the funny thing
i think of it like this
going by the dynos

log: boost by about 300rpm sooner make some decent power
full race: boost by about 300rpm later, make about 40-60 more hp

i think i can wait about 300rpm.

[McRussellPants]

Full Race / One-Fab / Peak Boost is definately fair enough.

I just can't justify a T3/T04 Topmount without building my motor.

I'm prolly gonna go with peak preformance and heat wrap it. Judging off the rest of the stuff on their site (which seems quality / useful, no JDM garbage) I'd wager that its well built enough to last its 350$ worth wrapped and its good enough for the 350whp Im going for.

Log manis are wack just for the fact that they sound like total ass.

[DJ_Sunrise]

dousan, i suppose a GSR motor and SR are that similar? yup. oh yea. thats real testing. id like to see that on an SR engine. dynos dont prove all that much man. real world driving is the true test, and like ive said.. i have either driven, or been a passenger in SR POWERED 240s.. ssac, mr, tomei, full race, kazama mani's.. ive seen them all.. experienced them all. to each his own. from my experience, i prefer the tomei :). it quieted my exhaust down, so im happy. to each his own.

are you a fucking ass?
did you read the post enthalpy did on the SR??? the one from freshalloy. same results. iirc 66hp and 30something ft/lbs torque GAIN above a log manifold (like a tomei is)

you lose again.
game over.

LOL.. DJ_Sunrise, that's such a convincing argument maybe Tomei should use it in their add campaign. I'm sold.
I like it so much I'ma use it in my sig.

rep points to u, manonegra. i like ur sig. haha!

[ronmcdon]

is the bottom mt full-race manifold a log manifold? really like to see how that and the top mount compare with the same motor setup. i'm not shooting for the higest power possible, just a responsive fast spooling 350whp figure. I figure the full race bottom mt would be the best both worlds, most likely better performance than a mass produced jdm manifold (pending dyno tests, if there are any), but more responsive than the top mount. its also a good deal cheaper.

[McRussellPants]

How does turbo manifold design affect exhaust tone?

smooths out the timing between exhaust pulses getting to the turbo.

SRs with logs sound like 4G63 trashcan.

I looked at the Full Race bottom mount, looks like it and the tomei operate on the same principal just the Fullrace is better all around. but it looked like you have to screwup the oil breather T, which is kind of hooptie.


DJSunrise needs to can it. of course a Fullrace is gonna have more power up top than a bottom mount. Why? T-T-T-T-T3 exhaust side and the turbo options that come with it.

"I rode in a car with a FullRace + 3037 and it had more top end than a Tomei + 2560."

Thanks Mr. Rocketscientist.

[hellion240sx]

there are conversion kits so you can use the t3's bottom mount. for money as well you can get hks etc. but from what i have gathered from here they all are prone to cracking. some more than others. its just a game of chance. some people run the MR for 2yrs+ without cracking. tomei is better for faster spool has OE design, full race is better for MO POWA!!!

How does turbo manifold design affect exhaust tone?

I went from a stock SR manifold to a full race bottom mount and the exhaust tone change was incredible. It did get louder but the tone is so much meaner.

This is a common thing (exhaust tone changes) when going to a tubular header from a cast one.

Dousan - You should get that sucker ceramic coated, mine looks mint and heat isnt an issue.

:blah: the point of your post? "flows equal air to full race." your ass (from sitting in your car) said your tomei flowed better than the full race a few posts back. fine. prove it. and while you're at it tell the heads at tomei you're doing them a huge favor.

[Dousan_PG]

you never tested it man
dont give me this shit
if you did PROVE IT
show it to me.

[Flybert]

AHAHAHAH this DJsunrise is hilarious. He's all about real world butt dyno testing and talks about how real dynos aren't the way to judge a product. Then when he realizes that was the dumbest thing he could have ever said to try and defend himself and his manifold, he then tries to put down the fact that the SR and GSR motor are different when dousan actually showed him the same results with an SR. As a last resort, he starts to bring up a company that flow tests shit and thermodynamic engineering like he knows what he is talking about. Hey djsunrise, <leans over> <sniff> you...stink.

[GlacierFreeze]

Hell even if they flowed the same (I dunno if they do or not) then the exhaust pulses would still be far superior on the Full-Race. Troll maybe??////

[sideview_180sx]

Sir DJ_Sunrise ....... you do realize the shop built the AEM civic and all those drag cars to different specs. Drag motors don't have to last as long as a sideways motor, nor get to deal with the oil churning around blah blah blah ... Full race knows their shit. Geoff is the man. I almost picked up there kit when I saw the EJ coupe daily driven with 530whp. 4-5 years ago. Just ask them for a flowbench printout I'm sure they will help calm your sphincter so you can be happy about your tomei mani. You can say this and that blah blah, how many shops have turned out so many fast 'drag' car with just there bolt-on products ??

[hellion240sx]

1. damn that fullrace mani is hot!!! makes me want to go top mount!

2. pete, i want to lick that mani, looks sweet!

3. got a chub

4. sunrise, you need more than verbal proof here, show it!

5. ok i'm no turbologist or anything. but what if you got like a .86 gt2871R and matched it with the tomei? would it come close to putting it with the gt2871R .64 and the fullrace mani?

isn't the reason that people go with the .64 over the .86 - faster spool as opposed to the .86 more lag than the .64 but more power?????

am i making any sense here?

[alexchanman]

im pretty sure the full race is almost a grand for a reason. if it performed less than the tomei than why would there be so much support for it??

BTW are you posting poetry in this thread dousan????? looks awfully like it.

[Dousan_PG]

i should reply only in haiku format only maybe haha

5-7-5 right?

tomei is shitty.
full race is where it is at.
top mount is the best.

dont turn this into.
a haiku thread for petes sake.
wont do any good.

but does it make sense what i was saying? anyone???

I would hope similar sized tubular pipes flow the same...

Who flow tests an exhaust manifold? How do you simulate the exhaust pulses? Cause that's what makes the difference. Short style joins the opposite pulses for the low end and the equal length separate out the pulses for less collisions at high RPM(pulses).

people go with the .64 cause there is that much less lag. however, on a manifold such as the tomei i can put the .86 on without the apparent lag due to the design. on an equal length header where there is more lag apparent, but according to dousan more hp.. the .86 would be very laggy. his setup hits full boost at 3800.. i just installed a boost controller, my 12psi is there by 3000rpm. btw.. dynos are not entirely reliable. you can go from one dyno to another and see different results by a margin. also, keep in mind that i can slap on 14" rims with rubberband tires and it will raise my hp and tq on the dyno dramatically because essentially i just changed the ratios of the entire driveline. same goes for diffs, and trans. changing gear ratios changes the whp. tuning of the engine is essentially possible through the tires, diff, trans. same goes for how warn down the tires are.. all effects the hp. so no, i dont like to go by the dyno for bragging rights and shit, its not all too reliable. simply cause one s14 has 300whp and another has 250whp doesnt mean that one can beat the other in a race.. plus, real world running conditions are very different from the simulation of a dyno. manufacturers dont slap cars down on a dyno and say.. heres how much power it has! they check that shit on a road. in ideal conditions. not on rollers.

DJ Sunrise. I was at the Nationals in vegas, you know howmany fwd cars had full-race kits, and were blowing shit away. plenty. done and done.

think of it like this HKS is supposed to best, hot shit, then why do there hipermax II suck ass so bad. jdm branding doesn't mean better overall. if you want to compare drag so much, why is it that the j-land guys can't seem to get down the 1320 with all that power?? I mean damn NA fwd cars are below 9s.

At some point or another you need to become the smart shoper and do your own research to make conclusive findings regarding things.... because if you believe everything that everyone says then your a pretty dam gullable person.

JDM tyte aint always so tyte :keke:

JDM tyte aint always right :keke:

Fixed. :rofl:

some people never learn, some do. catch me at pocono raceway, you'll learn a few tricks friends.

[Bigballin]

so ummmm what about them KA manifolds......

[hellion240sx]

ok so sunrise i guess it does make sense what i'm saying what set up do you have?

[tchenku]

all this arguing has got me all messed up!! i've got a gt2871r w/ .64ar on the way. by the looks of things, i would see no gains in a megan racing mani (other than change in exhaust sound) and i'm better off just keeping the stock mani until i can afford something better. am i correct? how's a stock exhaust mani coupled with an aftermarket dump pipe/o2 extension? will that yield any gains with just a o2 extension?

[redsuns3838]

a lot of interesting info posted here. a lot of BS too but anyways i have a question.

would the gains for a bottom mount Full race mani be as much as top mount? I wouldnt think they would, but would they still be decent? I dont see myself going top mount anytime soon. my cars still pretty stock aside from basic bolt ons. but ive always wanted an equal length mani so i was wondering would u still feel decent gains from a full race bottom mt?

[GlacierFreeze]

Has been debated before. Can't recall seeing any dynos comparing the two. I'd say if the runners are equal in length and size/shape the same compared to the top mount then the gains should be nearly if not totally the same.

Correct me if I'm wrong here....
