Not sure about this one , was once shown a 7/14 blade compressor "equivalent" of a GT3040R so could not be GT40 compressor .

Turbo , CHRA , Turbine housing A/R .

714569-0001 , 700177-0018 1.06

714569-0002 , 700177-0018 0.82

714569-0003 , 700177-0018 0.63

Do not confuse this one with 714568-0001/2/3 which is the GT3540R series and uses CHRA no 706451-0005

Where there are repeats in CHRA numbers mostly its the compressor and housing A/R's/type ie GT28 or GT30 that differ and this shows as a different assembly number .

Feel free to add or challenge the numbers as different lists often have conflicting numbers .

Cheers A .

[crack]

wow

[wolverine]

whatever we are paying you disco.......i say we double it.

[silman]

What would 700177-5018 be?

[paulr33]

hi adrian have you disected all of this info from the online garrett catalogs? or is there some other source ?

[grim32]

5018 and 0018 is the same thing, ive asked adrian about it before

[PHaT MR30]

hmm ill have to look as i have no idea what mine is......

Ash???

[stolen_s15]

Exactly what i was looking for. Nice work Disco

[discopotato03]

I was just about to say the same thing ... LOL .

[Gts-t]

Hey disco,

i couldnt find the turbo u recommended in this list.

"56 comp trim GT3076R based on the 700177-5007 cartridge (real GT3076R) "

Where would be the best place to get this turbo?

[bubba]

What numbers should I be looking for when buying a GT35R w/ .82 rear housing?

[Gts-t]

What are your goals bubba, what engine specs etc

[bubba]

Aiming for 400rwhp for now with huff to go over 500 at a later stage. Engine is an RB30DET with forgies, stock rods, NA cams, 550cc injectors, z32 afm and the other usual supporting mods. Tuner and mechanic have both advised GT35R with a .82 housing but other than that I don't know what I'm looking for.. need a specific part number so I order the right thing

Will be going on low mount tubular manifold with external gate.

Cubes and Mafia both have IW GT3076R's , Mafia up north and Cubes down south - or was that South Aus ? Anyhow depending on where you are you could ask them where they got theirs . All you have to do is insist on the 700177-5007 (sometimes marked as -7) cartridge (CHRA or centre housing rotating assembly) . The real Garrett IW GT30 turbine housings only come in three sizes so 0.63 or 0.82 or 1.06 A/R ratio (area to radius ratio) .

If you are really unsure or untrusting get them to send you a pic of the turbos ID tag and exhaust housing .

Just looking up the GT3582R with 0.82 A/R non gated turbine housing .

From Garretts online catalog that turbo is 714568-2 . For the 0.63 A/R turbine housing version 714568-3 and the 1.06 version 714568-1 . They all use the same 706451-5 cartridge (CHRA) .

If you wanted it in the propper GT35 IW exhaust housings you could talk to Brett Lloyd of GCG or Garretts franchise in Sydney at Chipping Norton .

Personal opinion , a GT3582R is a lot of turbo for an RB25 and way too much for me . I think its significant that some are using GT3076R's on RB30DET's and really like the results , to me this says that even this turbo may be a tad big for what many are realistically going to need on a street RB25DET .

95% of my time and some money is going into another project ATM but when I get to the R33 I think I'll look into the cropped GT30 turbine based turbos (GT2835/GT3071R) but in smaller 71mm compressor trims ie 48 and 52 . These were only ever HKS options though the cartridges are starting to become available I'm told . It urks me that Garrett won't do anything serious with GT30 turbine trims or make propper turbine housings for the cropped turbine but at least HKS make nice GT Pro S IW turbine housings for it and they are more common 2nd hand than the 3037 Pro S IW exhaust housing . I would also lean towards a T04B rather than T04E compressor housing with small and mid trim 71mm GT compressors because they are a fair bit more compact and would tend to keep the gas speed up with a smallish compressor .

For what I want this is the easiest way to go about it with conventional components , I'm not overly concerned about how many Kw's it could crank out because I don't have a need to go flat out everywhere .

Outa time , A .

[1400r]

and some of you guys complain why we have "which turbo for me" posts pop up all the time

[bubba]

Yeah it's not exactly straight forward

Thanks for the advice and the correct part number guys

[discopotato03]

I'm not sure how to edit my posts with this new format , the list I typed in 2006 eigth down mentions turbo number 700382-0008 Cartridge (CHRA) number 700177-0005 . I confirmed it is the HKS spec GT3037 with 48 comp trim option .

I don't think they have been made for some time and the only pics I ever found show them having the plain or non port shrouded T04E 0.60 A/R compressor housing .

[Dale FZ1]

48T GT3037 would be an odd-ball but still interested to see if anyone had ever seen or used one. I suspect it would/could have been spec'd for those twin GT3037 setups for RB26 that were floating around a few years back

[discopotato03]

Dale the twin 3037 RB26 setups I read about years ago were generally the 52 compressor trim versions .

Actually one of these 48T 3037's was sold second hand here in the past year or so and I would have grabbed it only it was pretty pricey and someone else was keener to spend the money than me .

HKS listed the 48T GT3037 as having the same power output as their 56T GT2835 but I suspect the 3037 with the full sized GT30 turbine would have been a better single on say an RB25DET . Also note that there was only one turbo part number for the 48T 3037 an d the few pics I could find show them all having non port shrouded compressor housings .

A few more happy snaps , cheers A .

[NissTrust]

What do you make of the new GTX series billet wheel turbos, have they hit the right combination comp housing to suit wheel profiles?

Comparisons between GTX3076r and GT3076 are starting to crop up.
