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.

so your saying the internal gate are no good?

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 it still spikes, just for now, turn off VCT completely by disabling it OR simply unplug the solenoid. Just to rule out excessive exhaust pressure. I recall a video from Motive DVD about a decade ago, where Hawkins original single Garrett GTX3582 or so turbo had boost control issues sub 1.4bar of boost as well.   Food for thought? Is there anyway you can peg the WG completely open and/or dodgily not plumb it back into your exhaust system for testing purposes?

      I will endeavour to give it a crack sooner or later. I have the wastegate apart at the moment so I'll replace it with a smaller spring just to see what it does and if I have to go back then so be it.   If it spikes to 23 but can then be controlled back to 20, then the gate must not be 100% open... So if it's not 100% open then why can't it drop the boost even further than 20psi (I understand it's not linear). What a headache this whole thing is.

      Either the WG is reaching full opening, or it is not. The "it is not" case could only occur if there was not enough time available to swing the valve fully open during that boost event. I would consider that to be unlikely, as this is a commercial product that is in use elsewhere, so it really should work. But in your case, because there is definitely SOMETHING wrong, it should not be assumed that things like that are working as they should. You should put a video camera where it can see the actuator (if at all possible) during a run to see how far it is moving.

      I think you're mostly on the ball there. With the straight gate, I suspect the weight of the spring will determine how quickly the gate can close, when not run with active pressure drive on both sides of the diaphragm. Otherwise, with drive on both sides of the diaphragm, you could almost go without a spring at all, only needing one to make sure that the thing was actually closed while completely off boost and not having pressure available to drive it closed. Butterfly valves have mostly symmetric loading when there is flow going through them, meaning that the gas hitting the upstream part of the blade is balanced by the gas hitting the downstream part of the blade, which means you don't need actuator torque to overcome any non-symmetric flow induced loads. But the gas flow does impart a purely normal load against the shaft, which transfers into the bush/bearing at each end of the shaft and does increase the torque required to make the shaft turn. Only a little, but it is there. I have no feeling for the amount of force involved in a WG application, but it certainly could make an argument for a decent spring weight being required. But all of this is just peripheral to the actual problem here.

      The answer to this would be I followed the documentation from Turbosmart which said each spring pressure could achieve a maximum of 5x it's rated pressure so the included smallest spring being the 6psi had a range up to 30psi. I went with the 12 because I figured it'd likely hover around 15psi as a base pressure however I was obviously wrong.    I have a log here that I'll dig out that is purely wastegate and no Mac valve controlling anything.   If it can't hold anywhere near 12psi, does that mean the straight gate is virtually wide open during a run? Or am I thinking about this all wrong.   I could Tee Piece into the cooler pipe pre intercooler where the wastegate gets its feed, and send that to the ecu and see how that reads, I just don't have a spare pressure sensor currently that's all.
