Guys just found out the serial number on my turbo i am still unsure of housing size think its .63 and a/r .70

serial number 700177 - 5014

ive tried to google search it and find it on the garret website but i cant get hard evidence on what it actually is??

can anyone help

i wanna compare it too a 3071r which im thinking of changing too on my rb20

im chasing 260rwkw full boost at 5000

at the moment im getting 260rwkw but full boost at 5500 - 6000

how can i compare the two??

That 700177-5014 cartrige is the one used in GT3082R (GT3040R in oldspeak) .

They are basically the GT3582R's compressor and housing on the smaller GT30 hot side .

Garrett don't show them on their website from memory and many people (inc me) think they have too much compressor for the turbine size but having said that some still like them .

GT3071R compressor is a 71.1mm 56 trim GT wheel . GT3082R's compressor is an 82mm 56 trim GT wheel .

For an RB20 a 44 lb (air pumping wise) compressor should be far more suitable than 62 lb one and noticably more responsive .

Possibly too expensive but a GTRS (HKS spec GT2871R 52T) is probably better again on a roadie or even an RB spec (T3 flanged) GT2530 .

Cheers A .

Thats a little under 350 Hp and at the crank I think its possible - provided the engine breathes well enough to do it .

Do somes searches on GTRS's and RB20's , Roy had some info on how these turbos stacked up against his Mitsy TD turbo and for an integral gate turbo they did reasonably well .

For me it'd be either GCG Hi Flow or 2530 or GTRS based on what I could afford to spend .

I recently put one of these turbos on my Sr (700177-5014)

With 270 cams, .64 rear housing i had full boost of 17psi by 4900/5000Rpm.

Given that post above info (cheers mate) I have a feeling i'm not even into the turbos efficiency range

I'm not terribly fond of the lag, so im looking for a smaller turbo and i think ill stick this one on the 3l.

anyway, bump for super old post.

+ found some info on the turbo here : http://www.sonicperformance.com.au/700177_dash_5014/Garrett-GT3082RL-CHRA/pd.php

Old thread revamp .

The thing is that the Garrett version of the GT3082R , once known as the GT3040R , use a larger trim version of the 82mm GT40 compressor than the HKS spec one did ie 56T for the Garrett marketed one and 50T for the HKS spec one . Both are made by Garrett but HKS paid for the development of their dialled in version and had exclusive rights to it for a few years .

Imo any GT30 based turbo isn't exactly small for a 2 Litre four cylinder but with Garrett its a big jump down from GT30 to GT28 turbines and turbine housings . I believe the few band aids like the cropped GT30 turbine are a crock and only recently proper turbine housings appeared for them - but in limited applications ie no T3 flanged integral waste gate option . I reckon this is why people go to Hypergear and TD series turbos because they bridge the gap Garrett isn't willing to .

For the record I had a HKS GTRS on my GTS25T and it made 271 RWKWs (E70 juice) on its knees and with falling boost pressure .

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
