Infiniti Q60 (3.0T) 6MT Conversion

JayRacing · Mar 26, 2024

I've created a thread on InfinitiQ60.org (https://www.infinitiq60.org/threads/infiniti-q60-3-0t-6mt-conversion.19453/) dedicated to How-To for a 6 speed manual conversion on a 2017 Infiniti Q60 Red Sport 400 (3.0T). This could be helpful for the Q50 as well. However, there have already been more Q50s converted than VR30 Q60s (only 2 so far)

I purchased this vehicle with the intent to do this 6MT swap. Previously, I have owned a 2003 Infiniti G35 6MT and a 2008 G37 6MT. I was very interested in the increased performance on the Red Sport 400 (3.0T), but put off by the automatic transmission (just my personal preference). I followed the development from Concept Z's 6MT swap and hoped to see them commercialize this conversion. Covid happened and CZP did not release a kit or any further information.

Therefore, I have figured out the details and would like to share them for anyone else interested in this conversion on a 2017+ Infiniti Q60. One benefit to the delay is the availability of parts from the 2023+ Nissan Z. I decided to use the trans and clutch from the new Z. Also, the same EDM (European) Q50 sedan manual interior console parts fit the USDM Q60 (coupe), as they do the USDM Q50 (sedan). In total (not including the research), this took 50 hours to complete. I had a local driveshaft shop modify my driveshaft. The full parts list is below. Also, a special thanks too the following who offered their support:

Nice what do you figure it came out to in parts? Any ECU tuning required after it was all said and done?

Geraldomi · Mar 26, 2024

I once read on the CZP article for the 6 speed manual swap that the ECU already has a checkbox to select manual or automatic trans.

JayRacing · Mar 26, 2024

For everything including the custom tune from AMS, $6,965.18

SkylineDreamz · Mar 27, 2024

Gawd!! My math was $10k, but I was also looking at using a 5 speed from a GTR32 or 33 so I can keep my AWD. Which then adds an adapter from LOJ. Beautiful work! Enjoy your now very unique Q!

A proper hand brake, too. Nice!

Sheesh way cheaper than expected especially with a AMS tune.

I can't remember the specifics but they had a whole bunch of issues with the transmission and ECU logic, think that was mostly tied to wiring harness shift logic, and engine response. They repurposed an older 350-370Z transmission so it wasn't designed for a VR30 engine out of the gate.

maybe @JayRacing can tell us about what issues he ran into and if they were similar to what CZP encountered.

JayRacing · Mar 27, 2024

Jake/Miles @ AMS had the manual feature set from the first tune they sent. This prevented the limp mode in the CZP article. It seems like there is better understanding of the Nissan ROM files now than in 2019. We did spend a lot of time tuning the throttle to get it to close as soon as one lifts off the throttle. Stock there is a weird delay that becomes very obvious with the manual transmission and clutch pedal. This presented as “Rev hang”, where the RPM spikes between gears.

BlaQBetty · Mar 27, 2024

This is the throttle closure delay that infiniti programmed in so that they didn't have to install recirc/bov's.

JNR · Mar 27, 2024

May have missed it but does the starter work from the automatic trans (flexplate) application to use on the manual (flywheel)? Often they have two different ones, least in the past on other makes (not sure on newer Nissans).

JayRacing · Mar 27, 2024

Yes, the ring gear diameter is the same. I’m using the original starter.

LethalRyanR · Mar 27, 2024

I just can't believe a new 6sp from nissan can be purchased for $2k or less. I searched it and it's legit. A really good deal honestly 👌

Aye was expecting at least 2-3K to buy from Nissan, manuals were always way cheaper than automatics though. Its why CVT's became so wildly popular they cost just about as much to manufacture as a manual transmission.

Awesome, thanks brother

Niiice! Care to elaborate? I've been eying the trans/transfer cases on the R32/R33 awd as well, without it in my possession but just by pics, specs etc. I was wondering if it could be done, since the V37 shares some similar specs and design from their lineage. I'm a AWD sedan as well

That might be what you need.

Yep! Joker beat me to it! Thank you, Joker!

400R, if you get to this while I'm still hemming and hawing over it, let me know how it goes, what if any snags you run into, and if your recommend the swap or not. I'll do the same for you if I actually pull the trigger on this. Lol

eljoker · Mar 30, 2024

Im thinking of doing it too. Been talking to a couple of my current techs and some that got out of the business. Could be something there just got to make sure my FEB will still work. I dont wanna chop up the car and lose features lol.

Hoping someone beats me to the punch.

@JayRacing I love this swap. I wish I had the time/money to do this. I would keep my Q forever if I did a manual swap. Great job! It looks awesome.
