So you have you driven a car with a GTX3071 and Tial 1.06? :)

GT35's aren't my favourite turbo, I have heard of too many failing, even at low (less than 20psi) boost, perhaps because they are so common?

The Tials don't perform really any different to the normal housings, they are just easier to work with, lighter and prettier so the results specifically for a Tial housing turbo aren't too relevant. A good friend of mine upgraded from a 1.06 GT3082R to a .82a/r GT3582R after feeling the lag didn't justify the end result and ended up with the same or better power EVERYWHERE, which to me indicates going to 1.06 on a GT30 is a waste of time if a GT35 can spool comparably and seems to in effect allow more efficient pumping overall.

Obviously not perfectly relating to a GTX3071R, but I at least feel that if you need more than a .82a/r GT30 turbine flow then you're really stretching it with a GT30 to the point its really the wrong size for you and its eventually going to wear out its welcome.

If I were running a 3.5litre V6 there is no doubt I'd be looking at a twin scroll T4 based GT35 (or equivalent) based turbo. I don't know what the people you are talking about are doing to their GT3582Rs, the only guy I know who has broken one (incidentally the same dude who upgraded from the GT3082R) did so after running ~28psi at track days over an extended period of time.... and it damaged itself after trying to maintain that boost level with what he later discovered to be a split plenum.

You might want to check out the XR6 failure rates. They are not a great turbo imo especially with the .5 comp cover which is the only one I could fit in the space I have. There is no way I can fit a twin scroll flange let alone the twin gates no matter how small I made them.

The 3082 isnt great either from the research I have done.

I would have thought the .82 GT35 rear housing would be comparable to the 1.06 GT30 in flow but its a moot point as that is the housing I have already and I literally cant buy the .82. When its back in stock I will get one sent out, hopefully they are a direct swap.

I know about the XR6 failure rates, and god knows what the reason for that is - I had the idea it only started happening after some change for the BF series?

Fact of the matter is GT3582Rs have been around for a decade now, been used extensively all over the world under intense conditions and proved themselves to the point of being more or less the definitive gatekeeper of sanity for modified turbocharged cars... you know what you're going to get and you know its going to work.

OK, it can't fit so fair enough but bagging one of the most proven turbos out there realistically folly. Why can't it fit, are you stock mounting it?

You are right about the GT3082R though, not great - which is why I'm a little bewildered at Garrett virtually recreating an expensive equivalent of the concept with the GTX3076R.

I certainly wasn't bagging them out, it just doesn't seem to flow too well with the .5 front. Hopefully the Garrett engineers have sorted some of the current issues with the new range. I agree that checking the filter is an often overlooked maintenance task but it would be a lot easier to block the 1mm restrictor without it.

Here is the space constraint I am dealing with.

And put it where? Im not ditching the airbox just yet, most of the US single turbo gear has very poor manifold design unfortunately and I cant run twins due to the front shaft and steering.

The manifolds should flow well enough as HKS managed to steal them for their kit, I guess I will see soon.

using the new GTX turbo (3582 equivilant, .86rear) my car just pushed out 630rwhp on e85, 27psi. will post a dyno sheet today. all my mod's are in my build thread...

extreamly happy!! maxed out the baby turbo though, specially the .86 rear. however i have a huge playing field with boost since it still comes on VERY early.

as i said...will post up the dyno sheet ASAP

Anyone ever had there back 3 cylinders turning off for a coupl mins then fixing itself. Every 45 or so mins on idle? Or after a few "blips of the throttlle"

They feel they have tried everything n that's why I am unable to comment on the gtx3076 :( it's not back yet.

They are still trying to nut it out.

Sounds like a wiring issue... should start a new thread for it as there could be much discussion for that.

Nice result on the GTX3582R (??) Stryder - look forward to seeing the sheet :) Whats the spool like?

Nah. All wiring completely replaced. Injectors are all getting injector pulse. Ignition is fine etc etc. It's been there over a fortnight longer than it was due. They are now trying more random and random things. Just in the hopes. They will find it. Just trying to research on my end.

;)

SAU search time :)

I've witnessed this happening, tucked the powerfc back into the footwell after a tune and it started happening, after a while of checking a few things it turned out re-seating the connector to the powerfc sorted it out.. it was like revving it shook the connector and made it work for a while then it worked loose again.. worth a try considering its free!

A loose ECU connector will do that, I put an alarm system in mine and it kept dropping to 4-5 cylinders, undid and screwed the ECU connector back in and it came good (had to remove it for the alarm)

    • 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. 
    • Hey guys, looking for these side skirts if anyone can help me out.
