Did ur turbo come with the port shrouded comp (slots around the comp wheel) as shown in the link u posted???

didnt see it before install. but doubt it.

my guess is that they are showing the 3076R instead which has the 60 comp housing and optional surge housing

My thoughts exactly.

False advertisement!!!

Not sure if it would class as false advertisement, more incomplete....

I think the main issue (as also experienced by myself with a bolt on kit from the same shop), is that they sell the kit as a bolt on package, and I also had to buy longer studs and a spacer which i wasnt aware of until the stocker is on the floor and the turbo doesnt clear the stock manifold.

I think its just a matter of either saying you need the extra gear or puting it in the kit and adding to the price.

^^ unfortunately the big internet suppliers like tweakit and hpbox (in my deliveries and expereince) supply a generic turbo in a box with a few parts. GCG on the other hand does all the housing clocking and the kit comes with everything (hoses, dump, spacer etccc) and it works out cheaper in the end as the fitter does not have to charge for missing parts or the time to re-clock the turbo housings or fab up actuator brackets...

The turbocharger facts as I see them . Anything Garrett BB with a GT30 turbine should be called GT30xxR turbo . The cropped version of the GT30 turbine is still a GT30 turbine .

HKS screwed this area up by calling their cropped GT30 turbine equipt versions as GT"28"35R . Take this to the grave , there is NOTHING GT28 about those turbos - except maybe the bored out bastardised GT28 IW turbine housings they used on CA/SR/RB26 "bolt on" "GT2835R" turbos .

Garrett turbos are virtually always described by their turbine series ie GT25/28/30/35/37/40/42/45 etc etc .

The cropped version of the GT3071R , this is the current systems real name for turbos with GT30 turbines and 71.1mm compressors , is not such a bad thing provided the turbine housing works with that turbine wheel . Sadly only HKS had GT30 based turbine housings made for that turbine while Garrett never did . They also bore out GT28 turbine housings to suit but the result is not terribly good - low turbine efficiency .

I reckon for the money spent they could provide the designed for the full sized GT30 turbine T3 flanged Garrett GT30 IW turbine housing , its dump flange is not the same as RB20/RB25 but the housing is the correct match for the uncropped 60 odd mm turbine wheel .

People really need to do their homework with turbos before they comit to them . I know people go looking for what seems to be a good overall turbo/fitting kit price but hunting for lowest price can be risky . You have to know every component required to get it in and running to have a realistic insight to pricing .

The biggest stumbling blocks tend to be the turbine housing and dump pipe and if you want best results you can't compromise either .

RB25 and VG30 turbine housings are not the best things to put GT30 turbines in because they are not designed to work with these wheels . Even the VG one is not big housing wise , big in the Hitachi range but not by GT30 standards . It can be done and can save some money on dump pipes but really those dumps are questionable when it comes to the sorts of exhaust gas flows a really flying GT30 turbine is capable of .

Best case scenerio for an IW GT30 turbo is the Garrett housing with a custom dump pipe or the HKS GT Pro housings with a custom or HKS dump pipe .

HKS do them for 60 and 56mm GT30 turbines , Garrett only for 60mm ones .

Lots of reading on this board about GT30 based turbos and various Skyline models .

Cheers A .

As Disco states, not alot of research going on, in this particular case anyway. Look, we all make mistakes, this seems to be one of them. Having said that, it really isn't a bad thing. These turbos will go on to give you a real kick in the pants at almost any revs above 2,700rpm. I bought my 3071 with the real 60mm turbine wheel and Garrett housing because I simply had enough of turbine restriction due to small turbine housings. Mine is the .82. Instant power anytime and the only thing holding it back is cams or a 3.5" exhaust or both. This sucker just loves to rev.

These turbos are real street turbos and can be exellent for scaring the pants off modified XR6T drivers. It's all about what your after, less lag means less power, more lag will give you the power but you have to pick your moments and be prepared for them. IE: right gear, right revs or say goodbye to that taxi on LPG. I for one have wanted to step up to a 3076 but how fast do you want to go ? What we have with the 3071 is the perfect street turbo, just wind the boost up and get that 260kws, you know you want to.

am happy with the car as it is now.

as smell mentions, its more about not receiving what was advertised. i did my reasearch and wanted exactly what was advertised.

it is false advertisment in my view.

i had a lot of success with my 3071r which had 0.71 rear OP6 housing, It did require a lot of work to make it fit, and almost every turbo will have to have the housings rotated to fit if they are not a direct bolt on replacement. 1 bar isnt really enough boost to get the most out of these turbos. Mine made 280 ish rwkw on 16-17 psi this was with cams tho. it made same power without cams but required 20ish psi to do the same job.

all in all. a great turbo with decent response.

With all due respect, read the terms and conditions...point 5 to be precise, and stop going on about false advertisement.

You got the turbo you ordered. It is EXACTLY the turbo you ordered.

There are two ways to fit the oil line so it is possible the mechanics fitting the turbo mucked that up. If Tweakit did, in fact, leave out the spacer or silicon by mistake, then sure, they made an error. EASY FIX. Tell them they left some bits out and get a refund for those parts.

the picture isnt really the issue here, the text is.

as stomper also mentions, ad is for a bolt on kit to suit the specific car. his spacer was also not included and studs were incorrect. This is false advertisment.

as for the 3071r specs on the site, they are incorrect. as i wanted the .60 comp and .82 ar i should have chosen the 3076r, which is the correct specs and on their site these are the specs also listed for the 3071r

I will speak to them about this so they can correct the site.

Possibly they are under the impression that the spacer is being supplied, or should be. Obviously it isnt. this could be miscommunication from their supplier.

as you said elite racing, money is pretty much spot on for what i did receive.

thanks for your imput here guys.

And on that note about wording, how hard can it be for a workshop to actually bolt the damn turbo on a particuar car THEN sell everything they used to make it work. Do NOT call it a kit if it isn't, that's false advertising. A kit is something you get from HKS vs our Australian idea of a kit which is any old turbo with something that might be the right oil and water lines, no dump, no inlet pipe, nothing. And then said work shops winge about customers being too fussy. CRAP, make something that works or advertise it as a partial kit or a kit that we think might work, oh, I know "buy our kit, we think it might work, if your lucky."

Honestly guys, just do it yourselves, yes it takes longer but it is done right and you know what your spending your money on.

      R32 GTR fuel gauge not working despite fixing fuel level sender

      By XoRoKu · Posted

      Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      You're confusing two different responders and more than one issue. The stock Neo ECU boost sensor is used by the ECU for protection purposes. It is essentially only an overboost sensor. It is not used for determining engine load for fuelling or ignition purposes. That task falls solely to the AFM. Any aftermarket ECU that either has an onboard MAP sensor or a plug in one, will use the MAP sensor as the primary load sensor. Or I should perhaps say "can", rather than "will", because some of them have the option of using other primary load sensors. That MAP sensor is not for the same function as the stock Neo boost sensor. The reason I recommended against a plug and play ECU is that they are intended to run a particular engine and usually in the car that the particular engine came in. So, if you have a transplanted engine in a different car, with some parts of the original missing (such as the boost sensor, for example) and therefore likely non-standardness of the loom and its insertion into the car's loom, then it is very likely that you will run into the same problems with needing to fix up wiring to make it work that you would with the stock ECU. And, if doing so for the stock ECU is enough of an obstacle that you start considering a standalone plugin as a solution, it should become clear that the plugin is quite possibly not the solution you'd hope it to be. It would just lead to more of the same type of problem solving work to get it going. In the above paragraph and in my earlier post, the lack of the boost sensor is not critical. It was just used as an example of something that we knew you did not have right, such that the stock ECU would not work. I took that as an indicator of a reasonable probability that there were other related problems hiding there.

      I can think of two places in my city of <1.5million population that specialise in automotive instrument repairs.Unless you're out in the wilds of Quebec, you have 3 major Canadian and 3 major US cities within the same distance as the single nearest city to mine. Surely there is somewhere you could send it.

      Can anyone shed some insight on this Turbo?

      By TurboTapin · Posted

      I never cared for twins but whenever these conversations came up, I always presumed the higher number represented a larger turbo. Learn something new everyday.

      how do i install this 3 port mac valve for boost control?

      By joshuaho96 · Posted

      Interesting, I've never seen a failure like that before but with the age of these cars and the general questionable-ness of all kinds of parts these days you can't rule anything out I suppose. Boost leak testing the boost control system would've revealed this though.
