reliable 6 speed

[SR20junkie]

Ive been searching but i cant find one i know the S15 6 speed likes to take a dump very often and i cant justify throwing money around, literally. So i was wondering if anyone could help me find a 6 speed that
A has a reliability factor of about 400-600 horsepower, and one that dosent cost me an arm and a leg like a dogbox.
B one thats made by somone that has a reputation with somone here, friends, family.
C dosent break my piggy bank, somthing that wont cost over 3500-5000 at total.
any replies are helpful and if anyone sees this post from the one i did last night, my bad i was really tired from 3 days of no sleep. thanks, John

I heard at one point someone was making an adapter for the G35/350z 6 speed, but I can't remember if that was for SR or KA.

3.dont make me repeat myself again

go with the 94+ 300zx TT transmission. you get dual synchros on 1-4. you will be under budget

and i seriously doubt you need that 6th gear

[Full-Lock]

i dont think the 6th gear is worth it.
just use s14 sr gearbox

[SR20junkie]

did you mean get the mazworx trans(because i didnt see one) or get the adapter kit from them and source a tranny myself?

He means to get the adapter from mazworx and source a tranny yourself.

[SR20junkie]

still though im looking for a 6 speed not a 5 speed i like it becasue of the ratios i get out of it, i like 6 over 5 just personal choice and im illing to pay for it and btw 94+ 300zx models it syas they come with a 5 speed so i guess im gona have to look into a 350z trans for my car...

[kyles1988]

or just go with the s15 6spd bc the myth of them not being strong enough is just that....a myth.

[SR20junkie]

is there an adapter kit for the 350Z trans to an SR engine? is there is can i please be told about it? or what I would have to do to make it fit/work on an S13 chassis?

what do you plan on doing with the car? drag/drift/auto x? you'll never use the 6th gear in any of those applications, you would probably rarely need it in any daily driving application.
if its some sort of all out speed contest, the 6th gear wont do much either. your engine can only reach a certain amount of rpms anyway. 6th gear means you have to shift AGAIN resulting in a loss of rpms and all sorts of other crap. its not really worth it.

and sixth gear would MAYBE net you slightly better gas mileage but by then you're going so fast, and putting out so much horsepower (you claim like 400) it wouldnt matter to begin with.

i went down this road not even 3 days ago, i was thinking about putting a 6 speed out of an ae111 onto my 4efte, but i did the math, and a 5 speed is just fine (even in my application 5th gear is barely needed because of the ratio spacing)

if youre set on using a 6speed (im still going to say go to mazworx, because then you KNOW you have a bulletproof transmission, and it will be cheaper if not around the exact same price) then go with the s15 6speed its not the fragile harlequin fetus everyone makes it out to be. you wont be putting down an astanomical groundpounding amount of horsepower so dont sweat it

edit: i probably didnt word this as well as it SHOULD have been but what im trying to get across is that not even the s15 needed a 6speed. its kinda cool to say "yeah, i got a 6speed" but its impractical and your money would be better spent on a transmission that was designed to handle a TT v6

[SR20junkie]

why does everyone like to neg rep me, all im tring to do is find a combo thats good for me! if you dont like a six speed thats fine, oh and btw i fuckin seached for 30 minutes here and 3 other forums, so thanks. i like six speeds becasue of the ratios i can put in them, and there are other reasons too but im not going to take the time to exaplin them becasue they deal with inertia phsyics, shifting ratios, and highway battling as an example only, also to get smooth shifts but have a bulletproof trans so i dont get a synchro up the ass if i so decide to do somthing stupid

[SW20Racer]

well if its any consolation, i didnt rep you either way. "highway battling"?? good luck. i guess i dont have to tell you this but its worth mentioning if anyone else searches and comes across this. shorten the ratios for 1-4 make 5 a little taller and six long as hell for this particular application but do your math to match your rpms.

[blownmotor]

Solution for you save your money and get a hollinger 6 speed sequential or S15 6sd with Nismo, OS giken, HKS, Grex internals or a custom 6 spd dog box

[bloodangels13]

I've found one place that has the Nismo reinforced cross 6 spd BUT its like 3.5k for it i want it so bad but its def not in my budget

https://www.rhdjapan.com/jdm-low/NISMO-Silvia-180SX-Reinforced-Cross-6-Speed-Transmission-20977

another option is to run a borgwarner t56 mazworx can make the adaptor (i already called and checked) but it gets pricey cuz you would have to run a tilton twin disk clutch and custom hydrolic throwout assy. i dont remember how much mazworx told me but it gets up there in price at least close to 3k

[98s14inaz]

6spd is over rated. Yes there are times when it would be nice to cruise in 6th gear but it's useless.

[a_ahmed]

^If it's so useless why are they made?

It's just the weight/size/cost constraint, otherwise having the right amount of gears and it being properly geared, it would help in a car's performance, handling/gas milage/drag/v max runs/etc...

There's always a give or take.. whether it to be short or tall... for tight corners or high way cruising... or top speed runs, etc... :)

I'm sure his reasons are valid... :)

I guess electric cars like the volt will make it kinda useless to think of many gears though :P

Fuel economy and fan boi's that buy them lol

Fuel economy and fan boi's that buy them lol

how do you get better fuel economy?

[MrChow]

If you want a better ratios what are you doing to do with your FD?? Why a lot of people don't have 6 spd swap in is because it's point less and a bit of waste of money. When really all you need to do is change your FD.
Look it up. Look up the ratios number of all of the tannys. Then do the math 4.03 to a 4.3 FD. You'll find want you want there.

[SR20junkie]

im making my own custom car , and i felt like putting in a 6 speed because imho they have given me tried and true love and i like more gears its a personal choice and i like drivability becasue i can have a close ratio gearbox but still maintain the ocasional fun session, if i wanted just different ratios dont you think i would have done that already?

[trsilvias13]

make your own adapter and try to fit in a t56 . they are pretty much bulletproof. You can upgrade to the viper t56 too and those things handle 1000+ hp all day any day.

But mazworx is just fine with a 350z tranny. They been proven, tried and true.

[Vernal]

If you put in a 350 tranny on an SR would it shift super smooth like a 350 or still have that mechanical fell like a 5 spd.

[HKsilvia]

Nismo 6 speed trasmittion for S15.
cost about $4000

[98s14inaz]

how do you get better fuel economy?

If it is geared properly it will keep your rpms at the appropriate level while cruising at highway speeds. The less work your engine does the better your gas mileage. For example if you drive the speed limit and shift at 3k you will get much better gas mileage. So if you like to cruise at higher speeds on the freeway, in 6th gear, your engine will be doing less work and your rpms will be lower. There are several cars I have driven that could have used a 6th gear, like the 5spd scion tc I owned briefly. Many manufacturers are even adding gears to their slush boxes to increase fuel economy.

[SR20junkie]

see, i dont see why everyone has to get down on me for thinking out of the box, some people understand what i saying.!!! (him^^^^)

[jspaeth]

I personally would like an extra gear on my SR....the stock gearing is great, but it could use an extra one....

I mean, when you are going 80 mph or 75 mph on the highway, she's revving at like 3500 RPMs...

Unnecessarily high if you ask me....it would nice to be able to cruise at 80 mph at like 3000 or 2750 RPMs

Just my 2 cents

Yea I totally agree. Even at the speed limit of 65 you are still revving at 3k which is pretty high. If we had an extra gear we could rev at like 2250-2500

you do realize that you just have 1 more gear 1-4th. 5th is 1:1 and 6th is OD. Where as a 5 speed 4th is 1:1 and 5th is OD. It's more to keep your car in the power band. The only way you would get better MPG is to change the rear end ratio.

[Silvia_S13]

you say your willing to pay for a 6spd since its your personal choice, but ask for a budget way around it. be a baller and go buy a hpi tranny. my friend jus put one in his s15 and loves it.

[projectRDM]

there are other reasons too but im not going to take the time to exaplin them becasue they deal with inertia phsyics, shiting ratios, and highway battling, also to get smooth shifts but have a bulletproof trans so i dont get a synchro up the ass if i so decide to do somthing stupid


Why would you want to shit a ratio? What does that even mean? I'm guessing you meant 'shifting', but that doesn't make much sense either. Maybe instead of buying a transmission, you should buy a real education, your teachers failed you miserably. I read that shit above three times and still have no clue what you're saying, although it does seem like you're just making shit up and talking out your ass. Am I right?

As for highway battling = illegal and completely ghey as hell. We'll print this off and send it to your parents after you crash at high speed, killing yourself and numerous other innocent people. They'll be so proud of their moron son.

[smelly240]

in most 6 speeds, 5 and 6 are both overdriven at the output shaft... take a corvette, camaro, cobra, evo... not many 6 speeds are 1:1 in 5th, the 350z/g35 is one of them that 5th is 1:1, tho. even a civic 6 speed is ovderdriven at the tranny.


either way - a 6th gear isnt all that great an idea. I'd rather have more power and wider gears than spend a lot on a 6spd.

[SR20junkie]

well seeing as how people like to neg rep me because im a noob but i think outside the box, i used highway battling as an example to get my fucking point across, i guess the people who neg rep just dont like that idea of maybe just maybe theres another school of thought out there, that maybe i dont want a 5 speed and i made this post so everyone could HELP me decide, not so you could come on here and just be an idiot and tell me what a bad idea this is, even those who tell me they wouldnt do it and what they would rather have thank you for the input, but i am still looking for input not negitive rep. would everyone like a clearer idea on what i said? 6 speed on the 350Z is in my theory a good choice of a gearbox because 6 is overdrive and 5th is direct drive. maybe this will help you 6th gear is roughly a .851 in THEORY and 1st is a 3.978, i would rather have 6 speeds to shift from 1st to 6th in order to achive a better, smoother shift point to get the same RPM's as you would normally get on a 5 speed. The difference is being that i would want this becasue of various reasons. the gear ratios on a 350 is ideal to me becasue of the smoothness of the TRANS is has nothing to do with the SR20.the rear end itself plays a role in fuel economy becasue it is the final drive. also the other reasons are that it would provide better fuel economy becasue the engine would not rev as high as with a 5 speed because of the ratio in the transmission. also because the engine would not rev as high, this would provide me with a wider powerband if i chose to tune the engine so. this is what im talking about, HAH like i would street race with a car that i love, that in itself is a stupid idea becasue when i would get caught my car would go bye bye and i would say "fuck that was a dumb idea why would i do that" and that in sommary is why dont even want to street race, but thanks projectRDM for being the ever so intellegent person you are for pointing out that i forgot to proofread and state it was example only, and no this isnt inital D but thanks:Owned:

[DC5RACER]

see, i dont see why everyone has to get down on me for thinking out of the box, some people understand what i saying.!!! (him^^^^)

how do you know what you like if yove never had a 6speed in your car before....its not like every 6 speed transmission is the same..people are only trying to save your time and effort and also your money dont get so mad over it. Its a really good idea if you really have nothing else to do but asking about it and doing it are 2 totally different things thats why ppl flame.

[SR20junkie]

ive personally test driven 6 speeds from niassan audi vdub and other car manufacturers to think if i wanted it, 1.5 hour test drive and i cant forget the rotory..thanks for the input DC5RACER!

have you had that 6 speed tranny in YOUR car with YOUR motor?

[SR20junkie]

yea i have 03 hundai tib gt tuned to 240whp

[MrChow]

Can we let this thread just die now?

So question you do know just having a 4.3 FD in our stock tanny will lower our rpm like the way you want. Also will better MPG like you want...
On the other side I'm going to go with you. You have an SR if I'm not mistaking and want a 6 spd tanny. I believe IMO, your best bets are S15 or Z32 tanny. Or there custom places, Nismo 6 spd etc. etc. The Z33 tanny has a ratios are match with the engine. The different power band in a stock tune SR20 to a VQ35 won't match the tanny you want. Well that's unless you tune it to match your engine. Did you get that? I'm not the best at explaining things. If not I'm sorry.
I know there's a better way to explain but I can't think of it just at the moment. Basically powerband and gear and FD ratios need to match up or else the car just won't pull right or the engine will have to work harder.
There should be something about that somewhere on the net. But there.

I also understand why you would want a 6 spd. I think it would be kool to have a 6 spd. But I'm stuck with the stock. That's why I'm going to go with a different FD.

[racepar1]

Dude you said it yourself, you are a NOOB! Why are you arguing with people that know infinitely more than you do? A 6-speed trans is a waste of time, money, and effort. The only time you would ever be in that 6th gear is on the highway and the only possible benefit is fuel mileage. If you plan on building a motor that is powerful enough to break the s15 6-speed trans then fuel mileage is basically a non-issue as a 400+hp motor will GUZZLE fuel no matter what. You also say that the ratios are closer. Closer ratios will have no affect on acceleration times and may actually slow lap times because you will be shifting more often. More shifts = more time not on the throttle. Stop being a fan-boy and start listening to people that have more knowledge and experience than you.

I see my name in there so I feel I should rebut your comment, but I've already spent an hour reading through that trainwreck of a post and cannot for the life of me understand a fucking word of it. I know English is a lost art, but I think my 3yr old neighbor from Czechoslovakia could do a better job at typing than you could. Their cat might even have a better grasp at language skills than you, at least enough to be legible in their message.
Bottom line, you're NEVER going to be taken seriously on this board (or in life) if you look like a fucking retard. I wouldn't waste the piss in my bladder to put out the fire you're trapped in so I sure as hell won't give you a clear, concise answer to an in depth technical issue when I know damn well you can't even grasp the common sense to form words and sentences. You may just be a really bad typist, but I strongly believe there's more to it than that. Prove to us that you're able to breath air and walk at the same time, maybe someone will give a rat's ass about your concerns.

[smelly240]

ok - now the gearing from a 350z 6 speed and a s15 are almost the same... so the gearing being "for a vq" isnt entirely correct. The thing that determines that more would be the rears ratio. and z32 trannies are 5 sp.

either way - just get a s15 trans if ur hellbent on a 6sp. or fork out the loot for a crazy gearbox.

stop wasting bandwith.

[!Zar!]

Stupid people make stupid thread.

Noobs think they are looking outside the box when they are only looking into a hole filled with a big fat crap.

[DC5RACER]

yea i have 03 hundai tib gt tuned to 240whp

lol cool i guess doesnt sound like its a 6 speed in your 240 though.....motors act diffrently to trannys just cause a hundai with a 6 spd is nice doesnt mean its gunna be the same in the 240. but hey just go be a asshole and stfu until you do it otherwise prepare to get flamed noob

[revat619]

I swear you guys are like a bunch of piss ant little kids....

Honestly, everybody needs to just shut the fuck up if they have nothing productive to add. He wants a 6 speed in his car. PERIOD. Pissing and moaning about why YOU think its a bad idea or why you wouldnt do it is pointless. ITS HIS CAR AND HE WANTS A 6 SPEED. Your OPINION on the issue doesnt fucking matter. Help or get the fuck out of thread.

ANYWAY, if you want absolutely want a 6 speed, i would suggest an adapter plate for the 350z tranny (rebuilt with stronger internals for your HP numbers of course) or like someone said already, an S15 6 speed rebuilt with stronger internals.

[MrChow]

plz let this die now... or someone lock it.
