Hi,

I was just wondering, I have seen a number of topics that have been started about people starting the processing of converting their 350GT-8 from the CVT to either a 6MT or 5AT.

None of these topics have noted whether or not the conversion was successful.

Can anyone tell me, has this ever successfully been done? It is an option that we are considering, changing our CVT to a 5AT. If we do this will we need to change the drive shaft, ecu etc? Will the triptronic still work or will we need to change the gear lever also? Our car also has the paddle shift on the steering wheel. Will these be rendered useless with the change?

We have attempted to do our own research, we have found alot of information that people have posted in relation to talking about it what they thought they would need to do, but have not been able to find anything that confirms what will be required or if the change was even successful.

I would rather find out now before we start the process of spending big $$$ on the car. Would much rather just scrap it out for parts if we cant either fix our problem or successfully change the transmission without needing to rob a bank.

Cheers

I don't know how much works is involved, but like all projects like this, unless you can get a comlete list of required parts from someone who has done it before, you are better off obtaining a complete donor car, that way, when you come across unexpected requirements, you have the parts available (eg, it might need a harness swap, ECU swap, etc)

    • Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise
    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
