I purchased this kit last October and found it to be excellent, although back then, the exhaust housing had a standard nissan 6 bolt flange on it.

Car made 235Kw before the injectors maxed out, with a fuel pump and Z32.

Only problem I found was that the space plate wasn't thick enough to clear the turbo from the stock manifold.

Turbo is supplied by GCG, so you know that they are good quality Garrett's!!

For the money definitely get one, if you put crap gear on your car, it will only haunt you later on, when it breaks.

The best thing was that the turbo spooled up at around 2800 rpm, so there was little to no lag from the bigger unit

what did you end up doing to overcome the spacer problem and also how much psi you ran to get 235kw

You will have boost control problems with the tenie tiny internal gate.

Get a 0.63 turbine hsg and a TiAL 38mm external gate and you will love it for the street or if you plan on a engine rebuild later on and more power and maybe track time go the 0.82.

i went the internal gate. Had a few issues with actuator and boost creep. Eventually it got sorted, would probably have cost me less if i went with the external. Pay extra now to save more later. I would buy one from a direct garret supplier too like mtq.

Seriously - try searching.

People are unlikely to continually post their experiences, especially about internal gates which are so well documented you could write a factual book on them, RB25's and the limitations :P

yeah I have been searching and everyone is saying 3076 with 0.82 housing is the best option, im just wanting to know if the 0.71 housing internal wastegate will cause boost creep as others have had with 0.63 housing, thats prety much the last question im left with, will 0.71 do the job with no creep or should i go with 0.82.

the 0.71 is a milled housing and cropped turbine.

Personally I want to leave everything at Garrett specs, so I've chosen the 0.82.

I think the 0.71 was designed for the GT3071 for 4 cylinder applications.

Ive had issues with the kits as they are NOT kits... they are just a turbo and other parts are needed, so be prepared to spend quite a bit more to get it installed. A few SR turbos customers have been bringing in lately need actuator brackets fabbed up etc... in the end it was cheaper to buy the GCG KIT (which is actually a bolt on solution, you specify the car model and it arrives setup) which had the correct actuator bracket and housings clocked to the right postion.

The Tweakit RB25 kits ARE resold GCG kits, but at cheaper price >_<

Confirmed by GCG themselves.

same price as the ATS GT3076 .73 AVO rear housing, Garrett CHRA, nissan hiflowed comp housing

Adelaide Turbo Services - rated to 280rwkw

bolt on solution

100% has my backing as the perfect RB25det turbo upgrade

looks like stock, goes 200% better than stock

ie stock 120kw, modified 240kw, same fuel consumption

>_<

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.

      Not required but appreciated. Super Coppermix Twin even the non-competition model feels like the pedal is noticeably heavier than stock which was pretty well judged IMO. I'll be swapping in the Nismo operating cylinder soon to see how that feels.  Personally I haven't felt anything that justifies replacing the damping loop, at least compared to more modern stuff where the clutch delay valve is actually quite noticeable.
