Changing My Cvt 8spd To A Manual 6 Spd-not By My Own Request!

Alright, well where to begin? I have decided to open a new thread in hopes that people in my position can get advice and we can help each other out, as well as get some advice and recommendations from all you experts out there!

Here is the situation: 2003 V35 CVT 8-spd=broken, parts are unable to be made, located or found, but you can buy a new one from nissan for about 21-28k, depending who you speak to. This is however obsurd seeing as the car is only worth about that amount in the first place!

The only solutions I can come up with after it sitting in different mechanic shops for over 6 months is to:

A.) Buy the New tranny for 21K

B.) Contact a guy in NZ, who claims that he can fix it and rebuild it because he has the parts from JATCO and wants 10K+shipping, but who is going to electronically transfer 10k to a stranger along with your broken tranny?

C.) Convert the Tranny to a 6spd Manual which is in the coupe V35 skyline? (This is all pending that a mechanic will do it and I have a few electrical wizards looking at all the wiring and the conversion, but nothing definite yet)?

From these choice, I don't think I really have another choice besides C. Any ideas?

Does anyone actually know the part number of this transmission which goes into the V35 coupe the 6spd manual and have any pics or the wiring layout?

If you do go with option B might worth a small investment to fly to NZ, checkout the guy's workshop and do some homework on local forums or people who have serviced their transmission in that person's workshop. If the guy's legit, it may save you $10k, as going for option C might cost a bit less than $10k I imagine (with parts and labour) and your steering wheel +/- shift paddle may not work anymore... plus finding a mechanic might be a challenge as these car is relatively new not many will know them as well as the old R32/R33/R34 range.

I had an R33 gtst auto to manual conversion - 4 yrs ago cost $5k parts and labour. for a car this new, go figure. estimated maybe $8k-9k but you do end up with a real manual. so both B & C is worth considering, but I not A in my opinion.

I feel for you man, and I hope that no one has to go throught that.

Out of interest:-

1) How many km's has your car got on it?

2) How does it "break", i.e what stops working?

3) What mods, if any?

3) What's your driving style in general? Anything excessive/track/donuts/dumping/granny driving?

If it were me, I'd put the car on a boat to Japan and go over and sort it out over there.

I agree that flying to NZ may save me 10k, but it might also cost me 10K in fixing it. If I could change it to a manual I would save a lot more considering (removal and instalation of the new tranny, flying there and back, shipping of the tranny to and from and my time off work) these costs may add up quite quickly to at least 4k). The thing that gets me about the Guy in NZ is, how did he get the parts? He sounds a bit too confident and I really don't think he can do it, but it is going to cost me at least 4k to find out.

What's the deal with having the car re-exported for repairs, and re-imported again - do we have to pay stamp duty again on 2nd entry?

Just curious on how this procedure work...?

Really good point and may be worth looking into.

If it's just the tranny broken, could you not ship that without the whole car?

Oh, and good luck with it buddy, i would be devestated. Unfortunately it's looking like the CVT is the model to stay away from.

Wasn't there someone else on this board who had a massive issue with the CVT?

With the guy in NZ kleenbeats on the forum has spoken to him and I wont post the comments made about what he was offering and how much he charges, last quote for a new one was just over a million yen FOB and Nissan local wanted $24,000 and was for a dealer.

I will get a current confirmed price for a new one Ex Japan and post it, the oil for the transmission does "not" have a generic choice like all other transmissions which can cause issues, oil is $1,500 local and $600 Ex Japan which has to go sea freight.

and keeping it auto would mean you won't need a manual pedal box and probably can use existing CVT 8's pedal box (accel & brake - no clutch pedal needed), and is the handbrake on CVT 8 is the same as in 5sp auto - which is actually a foot pedal next to the brake pedal?

in manual the handbrake is a real hand brake lever next to the gear shift lever, so again you'll be up to more parts to replace for going to manual conversion.

from my experience with them - you would need the auto controller if you were to toss a 'proper' auto in it. so that to me would be a harness swap. also the ECU is different in them. 350GT auto one is different physically to the CVT.

driftt has the best idea so far.

Still haven't ascertained what exactly breaks or the conditions leading up to the failure. Anyone know? This is with a view to helping us build some preventative measures at the very least.

As I understand it the 350GTs CVT is a unique design, not at all like the one in the Maxima or Presage or other VQ35DE Nissans (this is why I went for a 300GT with the 5 speed)

An entire car can be had from $12-13k NZD (which is a fair bit weaker than the Aussie at the moment), even if you had to buy the whole car and have the transmission removed and shipped it might be an option. You could sell the rest on to a wrecker or for maximum money have someone part the car out for you (I know I'd pay good money for the part-leather seats and the rest has got to be worth something). Obviously the problem here is its a logistical nightmare you don't know how much life the new box has in it.

Edit: The CVT guy in NZ may have access to a few wrecked/parted out cars which could explain things. Best to tread warily though.

      Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?

      Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened.

      Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging.

      Infiniti Q60 Navigation Update

      By Chocolate Cheesecake. · Posted

      I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
