It's a shame that no one will see it once installed.

I admire the man for his undying support and dedication to the Z platform. PROPS!:bowrofl:

Looks like Phunk is giving the power to the people.

Someone thought that this was just for auto tranny guys. LOL That is not the case, it is for the manual guys who keep breaking the tranny.

zguynate 04-03-2020 04:18 AM

Any updates on this Charles?

phunk 04-04-2020 05:31 PM

No I took a little break from it. Just started playing with it again yesterday.

I have decided that making the stock driveshaft work is going to hold up the project, so I will revisit that later. I don't have any reason yet to believe that my original plan for it wouldn't work, but I think it will take longer than I want to wait right now. I am going to spec up a custom driveshaft to order next week to get things moving along. I will need the option anyway, because even if I make the parts to use the stock shaft, I think most people will opt out of that option when they see how the stock u-joints are held into the yokes (stock shaft was constructed intentionally to not be rebuild-able).

Having gone from a MT6 Z to a GT-R, you guys that do this are in for some fun. Driving a DCT with paddle shifters is the ultimate video game!

Waaap, BANG, waaap, BANG, waaap..........:excited:

I have to admit, I run consistantly faster lap times with paddle shifters on my simulator. :driving:

Very exciting to see this moving forward! Makes sense to go with the dct over a zf8, much better aftermarket. Besides clutch upgrades, a number of companies have cracked control of the getrag.
MaxxECU and Syvecs have full standalone solutions, and HTG/DKGECU offer their own TCUs (I assume you're looking at the latter here).
Any idea if you'll have to cop an f8x dct shift knob? Would be real nice to keep things nissan.

In bmw world, these swaps are usually done to accommodate gear ratio changes or to get rid of the slow ZF6. Never seen anyone do a manual to dct swap, I'm sure that will make integrating a controller a little simpler. Also the flexibility of FD ratios on this platform is a huge perk we don't have with the e9x/e8x cars.

phunk 04-23-2020 02:26 PM

We wont be using Nissan shifters in our 2 test cars (aside from the bolt-in paddles). However, any vehicle owner that chooses to do the swap will naturally have their freedom to use any type of shifter solution they wish to construct or wire up.

phunk 04-23-2020 02:31 PM

As for an update, The driveshaft got here about a week ago. Its pretty nice, a little lighter than stock. By the time I add the adapter to the front of it, it should be about the same weight as stock or maybe a pound heavier. I will get that adapter made any day now, just havent had time to work on it... very busy season.

This year has been a wild ride. Can’t believe it’s already halfway though august. Well Saturday I wrapped up the physical install of the trans by building a trans crossmember/bracket.

What an Achievement, looks Super nice. Any idea when you will have a conversion Kit Available. I won;t lie, looking at that made me Firm. Cheers.

I did a manual swap on my car, the worst part is installing the clutch pedal.
If you didn’t move a couple pins from the BCM and IPDM then you will have the key light. Also reconfiguring the BCM with a MT part number and reprogramming the ECM with a MT part number(assuming you’ve done that) should finish off the electronics side. If you need any info on which wires to de-pin, or which wires need to be added to gain a real factory feel and look, PM me.

Nothing worth mention. I am catching up on a massive backorder log jam here before I can start on a production run of the adapter plates. I am hoping to make some moves on it in December.

Due to time limitations with working on cars this year, I actually just pulled it all out, had it anodized, and sent it to Seb. So any progress as far as having it running in my car is going to be postponed until far into next year, as I wont have the parts for myself again until the production run comes.

Check out SpecialtyZ's IG post to see a preview video of the first DCT 370z running and shifting gears on the lift. We are in the final stretch.

I heading to Seb's on Saturday so I can check that bad boy out in person!!! Time to start saving again.

Spooler 01-27-2021 08:36 AM

I like rowing my gears still. I will hold onto my H pattern for as long as I can but my input shaft is going to hate me. 3rd gear too. Glad to see this is up and running so I can have an option
to do it if needed.

I hear ya, but depending on the road coarse not having to row your own can be a couple of seconds or more. Paddle shifting is quite fun on a road course.:driving:

i want a sequential, but this is also very cool!

DCT is actually faster than a sequential. There is a reason Porsche, BMW, Audi and others don't use sequential in their racecars.

yeah I know, I just like it more i guess.

Last year I was buying a Honda Africa Twin (before covid happened)

And I waffled back and forth whether to get the DCT or manual with quickshifter. I know the DCT shifts much faster than any human could. But I ended up deciding on the manual because I thought it would be more fun.

IMHO it depends a lot on the power level. Over 500-600whp, shifting yourself can be frustrating as it really holds you back from getting the most out of your investment into the power, and your competitiveness. There was not a single time I drove my GTR that I wished I could shift the gears manually. DCT I think is equally fun, just in a slightly different way. Its insanely aggressive and efficient, and the shifts are so damn satisfying, you wish you had 20 more to go through.

Spec Jay 01-27-2021 05:11 PM

Hmmm... wonder if this will be legal for GTA street class...

Any idea on weight difference between the 6mt and the DCT?

phunk 01-27-2021 05:25 PM

Its tricky to get a fair weight comparison since we have to compare a bit more than the trans itself. Need to take into account the clutch and flywheel kit on the 6MT versus the flywheel and adapter for the DCT, different trans mounts and driveshafts. I can get numbers from just the trans pretty easy though as I have them sitting side by side on the shop floor and a scale isnt too far away. But my back isnt in the mood to lift them up right now :)

I don't think so for our cars. You will have to jump limited class or higher. You can't run street class anyway being boosted I didn't think.

I ran street class last year. Power adders aren't restricted (nothing written in the rules against them) Tons of S2000's with superchargers too.

The only thing the rules say for transmissions is "Sequentially shifted gearboxes are not permitted unless OEM. Gear sets are open"

Guess it depends on the interpretation of "Sequential" but my thought is no based on the fact that the DCT can skip gears if you tell it to.

Completely understand haha would be nice to know sometime down the line. I'm sure the time savings will outweigh the weight tax though.

Hotrodz 01-27-2021 06:09 PM

Also if there is any weight gain it is in one of the best spots low and mid carish.
