I was poking around at the Sequential gear sets for the R32, R33, R34 GTR and they are 17k or so. The normal helical gear sets with heavy duty syncro's are around 4-5k. This may be a no go for most folks.

I've looked into gear sets before for the Z. Slim pickin's. The people I talked to years ago, said it would be $$$$$ if they did it.

At least you got someone to talk to you.

True, They have went silent now since I asked for a billet input shaft. New tranny from Nissan is around 1800. Just the parts for an upgrade would be around 4 to 5k. That is not installed either. Most folks don't want to spend the 1800 for a new tranny. No way will they want to spend on just the upgraded gear set and synchro's.

What do you think install costs might be? $1500?

To install the gear sets? If the tranny is already out. I figure around $500 or so unless they have to do some machining. It's not hard to take a manual apart. Machining is a different story.

I've had the BorgWarner T10's, Super T10's and the Mopar Hemi trannies apart and swapped out the gear sets with either Nash or Liberty gear sets.

The last Nissan one I worked on you needed a press to press stuff on and off.

Last week, I ordered oem synchros, they should arrive in two weeks from now.

Or just order a built transmission for 3k

Maybe next step, I am taking my chances with $400 investment as the transmission labor will be free of charge

I am waiting to see the results of the DCT conversion as Seb is pretty close on completing the install on his Z.

From where?

Time attack guy. Fully built transmission.

That's the name of the shop or what? I couldn't find anything based on that information :confused:

Lol
No I forgot the name
Of the shop. It’s on a piece of paper somewhere in my
House.

levelten makes a built transmission, 700hp or 1000hp specs

don't know much about it but its 5k or so according the the website

edit:

I thought the LevelTen package was only offered for the 7AT.

Yep looks like that's the case. My mistake he must be talking about something else

Level 10 is trash. I have a man trans.

a press, pin punches, tons of pullers, a specialty non standard snapring pliers, 3 or 4 custom tools unless you want to spend a few hundred dollars on the kent moore stuff, and a bunch of other ****. I have been working on one of these bastards for a couple weeks now on and off. spend a couple hours trying to get a gear off, break down and order the specialty puller wait a few days to a week and then repeat.

oh yeah and pray you dont break one of the parts in the transmission that nissan doesnt sell or you will be buying a whole other trans to take that part out of

It looks like a promising project, if it worked as a turn key solution. The price of used M4 DCT isn't that big, on the same level of a new manual transmission.

LOL, this is the reason when my input shaft breaks I will just march on down to the Nissan dealer I worked at and order a new trans. You never know, I may get one just to have it when the time comes.

So....... in other words. Nissan engineers worked their magic on screwing a manual tranny. :icon14:

That is probably what makes it as tough as it is. If it were not for the input shaft issue I would not be too worried about it.

Any updates on the SOHO built 6MTs? For those of us who are simply looking to reinforce the synchros for hard driving, drag racing, etc. but aren't pushing crazy numbers (500-600hp) would something like WPC treatment suffice?

I talked to liberty at PRI and they will sell faceplates now. So you get your trans taken apart, ship off the gears, they add the faceplates and ship them back to your builder. Or you can ship them a complete trans for a good bit more

Lady’s and gents. I think i have found the synchro ring that chris was using. Unfortunately i cant find the part number ANYWHERE on this thread and obviously we havent gotten a response back for the part numbers so it looks like he might of just went dormant.

Ill update you all on my findings once i can confirm the synchro is the one in the picture he used. Im 90% positive it is though.

Im going to tear out my spare old trans and see if the part i found works. I dont want to give out bad info and have people buy synchro’s that dont work.

Ill let you know by the end of this week, should have the trans on my bench soon

I got some realllll bad news for everyone lol. I actually contacted chris via instagram, and he was willing to help with the information. I told him we were all wondering what these part numbers were and off of what transmission from a ford did he find the synchro’s. Heres what he told me :” They were custom synchros I had lined. The idea came from our abuse of the 350/370 trans in road racing. Tremec made carbon lined ones for the T56,TKO, and 6060 transmissions. The issue with us building them was an OEM box was only 1400 at the time and on the shelf. Just a run of the liners for the synchros was 30k. We made two runs when APR was footing the bill and I kept several sets after they sold off the Nissans and went to the KiA“

And then he stated “ Sadly the cases flex to much to even make it worth while. The OEM stuff is good, but a billet case is needed to make anything last. I never looked into making one from billet, we welded some gussets in some to test and never got it tested.”

I found the exact gear that he posted on this thread. Its a carbon lined TKO 500-600 synchro gear from synch tech transmissions.

Heres what i was thinking and how to go about getting better synchros. My first option is getting a 370z synchro and having it cyro treated. All the gears/shafts i want to be cyro treated as well. The 300zx looks super close to the 370z trans so i want to order one ring and see if the ring works with the gear set. Obviously the teeth have to match. Also they make a carbon synchro ring for the F51 trans which i will try buying 1 synchro and seeing if that works as well. If all of this doesnt work then ill just stick to the cyro treated option. Its super weird that they dont make any CD009 carbon synchro rings. I will contact sync tech and ask them if they plan on or have any carbon lined synchro rings for the CD009 or JK.

Sorry for the bad news fellas!

It's just not worth modifying the stock trans. Folks have tried and they still blow gears to pieces. I have been watching for a while. If I do something it will be another stock trans or I will swap in a DCT or a Sequential.

Have they tried cyro treating the gears?

Yup, even installed Billet gears. For the amount of money you would have in the factory trans swapping to something else is a wiser move. T56 swap it if you want to keep the manual trans.
Me, I have other options. I can run a DCT or go to a Sequential with my Emtron ECU.

The stock factory trans can take a ton of abuse. It is just when you get on a prepped surface when the problems arise. Can't leave out No flat foot shifting. It hates that also. It is amazing what it can
take right out the box. I have been over 700whp for quite a while.

I agree the trans is extremely impressive. I have some REALLY good news!
I contacted NISperformance and they said they had a CD009 carbon lined synchro ring in the works. Should be ready in the next few months!

We finally have a fix for the garbage synchro's in the car. I will fix my 5TH gear synchro and then re-build my old trans with the new carbon synchro's when they are ready. I informed them that we could create a group buy to try and get some sort of discount. If you want to be put on their list of people to notify you can just email nisperformance in their contact section or PM me and when their ready ill email you back and we can do a group buy like that!

Im extremely excited for the fix.

Also i agree whole heartedly on the flat foot shifting. Big no-no. Also ive tried MT85 with redline and when i put that in the trans i started having major issues. So i use the factory stuff.

let me know whos interested in these rings, im not profiting from this what so ever also just incase anyone was wondering. Nor do i have a tie to Nisperformance.

Idea on price?

Be interesting to see if those synchro’s with a billet input shaft can hold 1000whp. The stock does ok with 900whp.

3rd gear may still grenade. I keep waiting for mine to explode and lose all the teeth. My days are numbered. LOL Reminds me of my 1975 280z turbo. I crapped out three transmission before I finally found a factory 1981-1983 turbo T5 to put in the car. It just shifts like crap. That's why I don't care for a T56 if it shifts the same. I will pass.

Company in Australia taking pre-orders very soon. Uses a t56 input shaft and a bunch of gm parts to build the cd009.

Here you go. Get on the pre order. Ain’t going to get any better than this unless you want a built t56 swap.
