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.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
