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.

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.

Peace
Drew

[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.

PREACH ON, call Lance @ JGS precision, they got some new joints on the low, way better than nismo trash....

JGS precision FTW

my FULL RACE mani arrived today


yeah everything else on the market is junk
hahah
this thing is amazing.
lifetime warranty
robotic welds
inside and out
perfect collector

wow

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.

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.

enjoy...

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

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... Everyone has their own brain to make their own decisions.

[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.

i cant read japanese
thats like making someone sign a contract in another language.


how about this thread from FA

Full Race Vs Log
http://forums2.freshalloy.com/showth...ight=full+race

end results:
full race power: 360.12hp/266 tq
log manifold power: 300.14/231 tq


full race=lifetime warranty

tomei is probably fine but id drop for a PEAK BOOST manifold if i couldnt get full race
lots of companies make good log manis too

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

[EchoOfSilence]

you.... you bastard.

prostock or prostreet?
pics?

[Dousan_PG]

um...

its so purdy
i put it by my bed so when i wake up..
wow
its amazing
hahahahaha


pics this weekend
the collector is so perfect.
welded inside and out
split on the mounting points on the head to elimate crack issues
heavy duty mama.

and lifetime warranty.

[Dousan_PG]

yeah buddy im totally looking forward to it1 haha

the goods so far...more n the way of motor rebuild shit.



turbo is t3/t4 .48 ar iirc..i dont think it was .64
i have ot check again i have the worst memory ever

[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.

oh snap (562) posts lol

[Dousan_PG]

cams are 256/264 toda retaing the ncvs
im going to be using a PFC
no djectros for kouki so ill use Ljetro still (sigh)


manifolds.
megan is ok
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.

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.

[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

[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?

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. 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. 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??

t28 will boost fairly quickly regardless of manifold

no really, you're kidding right?
