Car is in with the mechanic now - major loss of power + shaking.

Multiple things need doing but the important one at the front of the car is the Turbo.

From what they have said something about a wastegate actuator is stuck open and won't close? I'm sure that means something to others and as a result the entire Turbo probably needs replacing. It's making no boost.

They're getting back to me tomorrow for prices on a bunch of stuff but I'm a bit iffy on the Turbo. I was under the impression that a replacement for the M35 Turbo is hard to find and that is why most people rebuild.

How hard is it to get a replacement Turbo as opposed to a rebuild?

EDIT: It's about 50/50 that I'll even bother repairing at this stage though, rear shocks need replacing, a bunch of seals etc, coilpacks, turbo. If it breaks over 4-5k then the car is going to be sold as scrap.

up to you, most people install coilovers anyway and coil packs/spark plugs will probably sort the shaking and running like shit (if its a misfire).

going to have to be a bit more descriptive than "a bunch of seals".

if you're not interested in doing any of the repairs yourself, i would at least take the list from this workshop and get a second opinion.

Spoke with my brother who is an apprentice mechanic and he'll help me out if I want to.

He questioned why I'd replace the entire turbo and not just throw an external waste gate on? The fins in the Turbo are fine, it's just the wastegate won't close.

I'm in Brisbane now.

Regarding the seals I don't actually remember, but they were kind of an afterthought in the discussion so I gather that's a cheap fix. The bulk of the discussion was on the Turbo, Shocks and Coilpacks. I think he said #6 needs to be fixed and is responsible for the shaking of the car so that'll fix that side of it but he also said to replace all 6 at once.

The Turbo he said is not boosting at all, zero boost.

Depending on the prices I get tomorrow I'll probably get them to take care of the Coilpacks and then hand the rest over to my brother. My partner is kind of at the point where she'd rather bin the car if it's more than 4k. I'm not having much luck convincing her that spending 4k on repairs is still better than spending 25k on a new (second hand) car...

Hit up Scotty for a wastegate actuator upgrade! Install it and Problem fixed!

You would have little to no room for an external gate and if you did and are still running the stock internally gated turbo what's going to control that?

Ha, my bro has been an apprentice for 2 months I think. I more meant I have access to a workshop and he can help me rip parts out etc. He didn't just say "an external wastegate" but I'm not mech minded so cut it down.

I've no idea what the wastegate actuator upgrade from Scotty is but I sent him a PM - if it fixes the issue and it's less than upgrading the turbo then it's a done deal. My car has 210,000km on it now so I'm surprised the entire Turbo is still alive but it is.

Thanks to both of you for the info :)

no worries mate yep Scottys actuator upgrade is a 1bar actuator with and adjustable arm will bolt strait into the turbo with the 5mm bracket he does. If your turbo is still running sweet and it's just the diaphragm in the actuator is gone that's all you should need! Scott will sort you out mate [emoji106] hope you get it all sort at a decent price would be a shame for absorber one to be sold off for bits there no that old and a great car!

Some mechanics will say the turbo needs to come off to replace the actuator as access is difficult.

If that's the case you'd want to consider a rebuild anyway with 210000 kms on it

Ask your mechanics if they can try and fix it in place

I read somewhere a genuine Nissan replacement is over $2000 just for the turbo.

High flow service for $1200

Turbos are like tyres, you just have to replace them when they are worn.

Good luck.

If your current turbo is stuffed, yes it will be worth it as u don't really have another option other than brand new Nissan or roll the dice with second hand (not advisable in a stag, due to difficult access for removal). I would suggest the smallest possible high flow. That should work well with stock setup. It will be a little laggier but that's the way it goes. Before you do anything, get a proper diagnosis. You don't want to be waisting money on things that aren't required. If it is indeed your wastegate stuck open, that will be the issue of no boost and the turbo itself is probably fine. I had a similar issue on a different car and it wouldn't make boost until 5k rpm. Fixed the waste gate issue and was boosting perfectly again. Good luck.

Yep - still wanting for them to give me a call. If it's just the wastegate stuck open then for now I'll just look at fixing that. There is definitely no boost but I the Turbo itself is making no funky sounds and I specifically asked if the fins were okay and Nissan said they were but I'll need to look myself so I'll take the car up to my brothers, try and get the Turbo out and see what is going on.

Nissan advised me to find my own shocks and turbo - think their parts guys wanted $2700 for a new turbo. They did find lots of cheaper options but business rules mean they have to go through their set suppliers and can't do random repairs.

All up what they are doing is $1900 which includes a service, diagnostics (I think about $300 or so is diagnostics). I have already forgotten what some of it is but it includes replacing the Coilpacks (including 6 spark plugs), something about my transmission manifold, full oil change in the transmission and a few other bits and pieces.

Happy to pay that to them and then I'll get the Turbo and Shocks sorted on my own.

Always had it done at Nissan - tried a few independent guys and they took too long and didn't provide courtesy cars or provided courtesy cars that were from the 1970s.

We have one car and my motorbike with a 1 year old. We need a car, combining independents being slow + no courtesy car means they have to come in a lot cheaper to make up for the inconvenience of me having to go and hire a car.

DrLui is wrecking his stolen M35 here.

Grab his shocks.

I wouldn't go to Nissan unless I had a new car under warranty.

Look what they charge for an AFM

Find a mechanic who has a passion for performance cars and is known for their good work. ;)

I'll speak with DrLui and see about his shocks.

Got the car back today. Turbo feels fine tbh. If it's broken it has been broken since I got it. I'll take it to my bro and we'll remove it but I'm not sure what I'm looking for so we'll see what we find haha.

All up I had the oil changed, oil filter, few lights in the rear fixed (brake light and normal light), all 6 spark plugs, all 6 coils, two gasket rockers, new gasket oil pan, full transmission flush with new fluid, bunch of hoses replaced with hose clamps etc and it came to just under 2k. Probably could have done it slightly cheaper but it's running well, gear changes are super smooth.

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number.
