I bought this car way back in April 2003, it had only 34000kms on the clock. For the last 11 years its has been my pride and joy, well looked after, always garaged, oil change promptly every 5000kms with only Penrite products, currently running 15w-50 full synthetic engine oil. Has only ever been run on 98 octane fuel with NGK plugs, currently BKR6E-11 gapped 0.8mm. At 100000kms it had its appropriate service with Gates timing belt fitted. Never had any problems with the vehicle, has always run great! Apart from aftermarket modifications, the suspension bushes have been replaced, new steering arms and tie rod ends, new starter motor, new genuine nissan radiator fitted in the last 18 months. Dynotuned 14 months ago at Federation motors in Cairns and makes over 400hp at the wheels comfortably at 18psi of boost, 98 octane fuel. This car has been great to drive, never been in any accidents, holds many memories, will be sad to see it go. I believe my car represents great value at $10,000.
Here is a list of modifications done to the vehicle, most carried out in the last 2 years, like turbo, airflow meter, injectors, fuel pump, coil packs and clutch...
NISSAN SKYLINE R33 GTS-T series 1 RB25det
- Garrett GT 3076 turbo (low mount)
- Apexi Power FC with hand controller
- Apexi AVC-R boost controller
- Apexi turbo timer
- Nismo 740cc injectors
- Z32 Air Flow Meter
- Exedy twin plate clutch (14 months old)
- Walbro intake fuel pump 255l/hr 500hp rated
- Tomei Poncam intake and exhaust 256 degree 8.5mm lift (not fitted)
- Splitfire coil-packs
- 3A Racing air intake (new)
- High flow 3' Jasma exhaust turbo back
- Hybrid front mount intercooler with engine fan crossover style alloy piping
- Remote oil filter installation, with oil cooler
- Oil catch can
- Tanabe Sustec racing adjustable coil-overs
- HKS blow off valve
- Autometer boost gauge
- Gizmo 2 stage shift light
- Rockford Fosgate cd player, with amp running a pair of Blaupunkt Overdrive 6.5' splits (front) and Rockford Fosgate Power 6x9's (rear)
- 18' Voltec Inter Milano wheels
- 235/40 front, 265/35 rear Federal 595 tyres
- Nismo GTR front bar, side skirts and Nismo rear lip
- HID driving lights
Please no time wasters, no swaps, genuine enquires only.

I have a pair of Tomei Poncams for a series 2 R33, VCT retained. But my car is a series 1 R33... Can these Cams be fitted to my car, would they need machining?
-
na he wouldnt, andy (hyperdrive owner/tuner) is real conservative on timing, especially around peak torque. on cars with mods like this one he always tunes down to 11.5:1 at peak torque then back up to 12:1 after that
OP: i have a proper garrett internal gate housing and dump pipe to suit for this turbo if your interested?
Yeah, i would be interested, send more info on what you've got..

The boost curve on that looks much like when I had the soft actuator, get a big can actuator and that'll really liven things up - the one supplied seems to open at about 11-12psi no matter what you do and makes it feel quite lazy.
In regards to the power made, mine still made pretty decent power on 15psi - GT3076Rs work fairly well at 1bar still, they just come into their own versus small turbos at higher boost... more due to the smaller turbos maxing out than the GT3076R NEEDING lots of boost.
Maybe that dyno is particularly harsh? Does it feel fairly quick on the road once boost is built up or is it definitely feeling like the 230kw number suggests?
It feels like 230kw, but i was hoping for more like what your car is putting out... It has a new 18psi actuator, which was specifically ordered for this turbo... Aftermarket 3' inch dump, single pipe not split system, aftermarket 3' cat and back exhaust, but standard manifold using spacer, 80mm metal intake pipe, tuner believes stock head gasket won't hold higher boost than 15psi, the car has got 115000kms on the clock and hasn't run any more than 1bar of boost it's whole life...
As I mentioned to trident150v - I'm a bit suss on the turbine housing, it could be a dodgy hybrid, the rest of it is the real deal. I noticed from looking at the back (exhaust side) of many GT3076 turbo's that there are two different types (apart from size) of internal style housings the open type (like stock turbo, this what mine looks like) and partition type, between turbine wheel and internal wastegate. Could that be the answer, choke-aholic hybrid turbine housing..?

Is it a real 3076??? sounds more like one of those choke-aholic hybrids?

Power curve looks about right. Could be that the dyno is reading lower than others. Are you running the stock intake pipe from the pod filter to the turbo?
Is there a reason your only running at that boost level? Seems abit low

Internal gate, 18psi actuator, aftermarket 3' inch dump, aftermarket 3' cat and back exhaust, but standard manifold using spacer, tuned @ 15psi because of standard head gasket...?

Id drop the exhaust before the cat and do another run.
But to be honest the 3076 doesnt really wake up until 18+ psi
and the response looks pretty good to me.
So check for obvious retrictions in the exhaust, and drop it for the next dyno run, Im not sure its that as the power doesnt drop off up top.
next would be throw more boost at the thing and see if the power goes up.
Only other thing I feel worth mentioning is, that the .63 will be choking the 76mm comp wheel, so you will never get the most from the turbo.
Is it internal gate or external gate?

I've recently had my R33 gts-t series 1 RB25 tuned with the following NEW mods: Garrett GT 3076 AR 0.60, Apexi Power FC, Apexi AVC-R, Nismo 740cc injectors, Z32 AFM, Walbro Intake fuel pump 255l/hr 500hp rated, Super Spark coilpacks, Apexi Power intake, 3' Exhaust turbo back, FMIC, NGK plugs gapped to 0.75mm, running on BP Ultimate 98, and this is the end result...
As you can see, the turbo is very laggy, and max power output of only 230.8rwkw @ 15psi. I believe the tuner has done best he can with the setup. How can I possibly get more power and response from the car, as quite honestly it was more fun to drive with the stock turbo @ 1bar of boost?

What A/F ratios would you suggest for tuning turbo applications on a rb25det with stock internals with GT3076 running preferably 18psi, for a save everyday street driver?
The optimum A/F ratio for N/A applications is 12.5:1 for best power when rich, and 13.2:1 for best power lean, so somewhere around there (If your intention is to tune it with an SAFC or something for better power or economy). WOT enrichment is generally to protect the engine/engine components like spark plugs. If you were to run a cooler plug, good fuel with appropriate ignition timing, you really shouldn't need as much enrichment, will get more power and better economy. Sometimes when maintaining WOT at high RPM on leaner fuel mixtures, components such as pistons can continually absorb extra heat (while the head and block are cooled sufficiently), that's when you use fuel to cool them. Generally you'd use somewhere at the lean end of the best power for part throttle, and somewhere around the rich end for at WOT, it really depends how high strung your engine is (compression/ignition timing/revs) and how hard it's driven.

Hi,
Anyone have any recommendations on dyno tuners in Cairns..? I've researched this a bit, asked around and found a lot of mixed emotions on this subject. My car runs a Apexi Power FC ECU.
-
What ECU?
Apexi Power FC.
-
The job itself is fairly straight forward if you have good mechanical skills. Download the RB25 engine manual and there is a section that covers cam swaps. Just follow that.
I see your located in Townsville.. Any good tuners you could recommend?
-
How many kms on engine? we are getting alot with valve float nowadays with any sort of cam upgrade... id say 3 in ten cars.
110000km's

Hi,
Looking for some help with cams... I've just bolted up a GT3076 A/R 0.6 with internal gate to my RB25 series 1 and I have a pair of Tomei Poncams 256 degree 8.5mm lift I would like to drop in. I'm not looking to get any real power gains from them, but just to move the powerband round, for more response and and earlier spool up, would these cams be adequate for the job? The cams came with the option VCT retained, what is this about and is there any tutorials or DIY's on instalment of these cams?
