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

>_<

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
