Just purchased my GT3071R

56 trim, 71mm compressor wheel

4inch compressor cover

T3 flanged with 0.71 exhaust a/r,

which mates up with the stock dump-pipe.

Cost me $1900 from Rotomaster in Melbourne

Would of cost me a further $100 for a GT30 style 0.63 ex-housing,

but would of cost a further $300 for a custom dump pipe.

Oil and water lines were custom made by HIS and cost me $330- all braided except oil drain pipe.

Some bango fitting from the stock unit were chopped and re-used.

BTW - Turbo needs a 10mm spacer between turbo and manifold,

as comp cover is quite large.

Stay tuned for further updates...(more pics/ dyno graph/etc.) :)

The compressor cover was hitting the manifold,

so I had to use a 10mm spacer and remove the four manifold bolts.

I replaced them with approx. 10mm longer ones

Below is a picture of the four bolts that had to be removed

and replaced with longer ones.

(4 bolts and nuts from Metric Man cost me $6)

The yellow rectangle highlights the section of the manifold

that comes into contact with the compressor cover.

Latter on i realised that it was not sitting flush with the manifold.

The heat shield had to be removed & the bottom right bolt had

to be threaded in 5mm deeper as i could not put the nut on it.

This is a picture of the set-up when I placed it on this morning at 4:30am

(Me and my mate were burning the midnight oil into the early hours of the day. :) )

the arrow is pointing to the bolt that had to be threaded deeper.

Will use a power fc

ATM: Mods are:

Full 3inch exhaust

Apex FMIC (its quite small)

HKS GEN 3 EBC

BOSCH pump

HKS mushroom filter

It made 211.2rwkw on 12psi with a SAF-C

Cannot wait till this one starts spoolin' :)

That looks like a big comp cover - no wonder you needed the spacer.

What is the origin of the turbine housing? 0.71 A/R with T3 flange seems a bit of an unknown.

Will be very interested to see how it goes for you. One of these should offer response and good power.

Any chance of a clear shot of the ID plate with numbers?

why the standard dump pipe? that will be hella restrictive!!!!!!

none the less top stuff :)

Ill be watching this thread closely as I am going an externally gated 30R on my 20

Just curious if this on a RB20 or 25.. I have purchased a GT30 with that .64 option above(have to look into the exact specs of it when i get it). Would be keen to compare if yours is on RB20, though mine wont be tuned till mid Janurary.

Are you planning on using camshafts at all cause Id also be curious to see what you choose. Cams are a unknown area to me and any advice I can get would be a bonus lol...

cheers Dan.

Its going on a RB25

Will probably put a set of 550cc injectors

Still debating on wether or not i will put camshafts. :)

Will post a pic latter on today.

The oil line comes out lower down and at the side of the block for mine ['98 rb25], did this change? Was it different for earlier models?

The photo shows the oil line coming from the back of the block?

Just curious........it could just be in the rotation of the housing etc

Pretty sure its the rotation.

On the photo the compressor and exhaust covers were not yet adjusted.

Im installing a Gt3071R as well. Certainly not a bolt on operation, just about finished though, should have it firing tonight

I know its a headache.

The next person that says to me the words 'bolt on' will lose his teeth.

Go to go know...back to thw garage. :dry:

Damn - some cool things going on with RB25s at the moment. I will watch with great interest at how the GT3071Rs go - I got >< close to going one, but decided a GT3076R in the end.

The RB25 dyno thread will be interesting watching soon!

    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers
