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 .

Turbine housing breakdown to come plus specs of Garrett "GT3071R WG" and the HKS GT3240 if I can find them .

Continued :

HKS exhaust housings to suit the 56.6mm 84T Turbine GT2835 series

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 :D

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 .

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 .

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

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 .

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      By The Bogan · Posted

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
