No need to apologise Cam, you didn't know all the details and the workshop really hadn't told you much It is sounding more and more like the bush bearing way is ok but the ball bearing option is the way to go. As GCG said if I went to bush bearing high-flow it would be a step backwards as such, this just confirms I'm defiantly going ball bearing

Stock 18"s? What condition are they in? i.e. gutter rash, nissan mech's with rattle guns etc lol What rubber you got on them? Just thinking about it, but I think the 19" Osaka rims will be the go

Bah! Your pulling our leg on this one ain't you? They probably felt guilty about over charging you for everything else they supplied or did

Just confirming that the stock key chain ONLY locks & unlocks the vehicle, there are no transponders in the unit, that is straight from Hornsby Nissan. That said, providing yours is not an aftermarket ignition/lock you should be sweet, the key you have just had cut should work fine.

Remapping of the ECU is one way (the way I'm looking at) or a E-Manage Ultimate or similiar piggyback system. Don't know what other ways it can be safely achieved.

ONLY if you use a Garrett Ball Bearing Core, that is why the housing had to be machined out and ended up shorter. With GCG they use all Garrett internals except for the ball bearings, which are a GCG make and allow the factory bearing housing to be left as is. Michael from GCG advised that the factory Garrett turbo was Ball Bearing and not Bush Bearing, Andy can take pics and confirm when his package arrives Cool, so the GCG high-flow rebuild *should* be putting out similiar levels of power, interesting stuff. I know it's not your thing Craig but I might need to investigate this further I thinks

<<-- more information copied from email - disregard the bit about the RB25DET, but atleast they have serviced these turbo's before -->> What brand are the internals that will be put inside the turbo? We use genuine Garrett parts apart from the ball bearings, which are our own design. Do you think the output will be similiar to the output of a rebuild with a Garrett ball bearing core? It depends what core the customer specifies, but the high flow will produce the same power up to the GT3071R range of cores. Do you have any power figures or estimate of powergain from having your style of rebuild performed? We have seen up to 250-260rwkw on RB25det with supporting modifications (ecu/injectors/fuel pump/FMIC etc etc) What type of warranty is given on the new rebuilt turbo? 12 Months I have also tracked down a picture of the Nissan Stagea OEM turbo, you may know of the turbo but I believe it's not all that common? I have seen a few of these, we have high flowed these units before.

I would have taken what Craig meant to mean - Standard Rebuild (i.e. standard flow) $650.00 High Flow w/ bush bearings $1250.00 I highly doubt the $650 is going to gain anymore flow than the standard setup, maybe I misread what Craig said but that's my take on the matter

Another wealth of turbo information in general http://www.turbobygarrett.com/turbobygarre...ech_center.html Should I assume a bush bearing is also referred to as a journal bearing? I can't find anything anywhere that confirms they are indeed one in the same. Interesting reading though so someone may find it helpful

LOL did you miss when Craig said that he gave his ARX a boot full of loving a few blocks before he got home with the newly fitted high-flow and his fuel economy went down to 1.5L / KM lol.. That really is like watching a second hand on a clock, poor fuel So no, some form of tune is still going to be required but at the end of the day if you pick a nice level of boost that suits daily driving the fuel economy is going to be an improvement anyway.

Yes, but the rebuild is only a standard rebuild which I would assume means all parts as per factory specification i.e. no performance gains Those prices were provided by Jetwreck (Craig) so it would be Precision Turbo at Wetherill Park. Are you so certain that your turbo is playing up? Are you sure you happy with the standard power? lol It's a lot of mucking around to pull the turbo out and then put it back in and decide later that you should have gone down the bush bearing or ball bearing high-flow road!! But to each there own, maybe yours has already been modded or something?

What we really need to track down is a complete list of Pro's and Con's for Ball Bearing Vs. Bush Bearing. I'm leaning toward Ball Bearings at this point in time, many reasons but one of them being is that the OEM turbo was ball bearing, whether or not ball bearing = better out put this is yet to be confirmed. Thanks for everyone adding their 2 cents worth

No, I didn't ask. I'm not sure if they have done any of that particular turbo, I gather it's special as per what someone else said. I'm not really that fussed on stats as such, but after going for a ride in jetwreck's car high-flow is a good option If you find one let us know, I've got a feeling you will come up empty handed tho! I think the VQ25DET is rare and may only have been used in the Stagea?! The VQ25DE is used in the new Maxima but alas no DET version. No worries, we are here to share our information and I like to give my bit back to the community as I get so much from the information here Jetwreck had his turbo high-flowed by Precision Turbo's and paid $1650 or something similiar, but on top of that he had further work to do to run the modified turbo, I'm sure it would have easily added up to or atleast close to $2k. Craig is very happy with the result, except the lack of power taking off from the line, but once the turbo kicks in your stomach takes a posie in the back of the wagon lol I was crapping my self (hope you don't mind me putting this here Craig, should be ok as we spoke about this the other night at the meet, it's a major topic for all of us who havn't done it yet!!) I also emailed a few other turbo joints but as of yet I have heard nothing back, GCG have been quiet helpful and very prompt in their responses to my silly questions I think I will go with GCG when I am ready to high-flow as they have a good name and should offer good support should anything go balls up.

<<-- copied from my e-mail for those that may be interested -->> Stephen There used to be a company called sliding performance that did bush bearing high flows, they lasted less than 6 months doing so. There are also companies that use Garrett ball bearing cores, this shortens the distance between the housings and also requires modification of oil and water lines. We @ GCG are the only company that use the factory bearing housing, and once the unit is modified, it is 100% bolt on, no further modifications are required.

All of these units come with a ceramic turbine wheel, that has a boost limitation of 14psi. Once this boost level is exceeded, the risk of losing the ceramic turbine wheel greatly increases. In upgrading this factory unit, GCG Turbochargers replace the weak ceramic turbine wheel with a larger than factory steel wheel. Whilst the unit is apart, all parts are replaced with new parts, such as the ball bearings and the seals. GCG also fit a larger compressor wheel, and machine the compressor housing to suit. A full gasket kit is also inlcuded in the upgrade. Once the unit is modified, there are NO further modifications required for re-fitting. Another advantage is that all factory heat shielding can be re-used, and the unit looks factory. The price to do this upgrade is $1955.00 Including GST.

Nick (Goldzilla) has the box of discs I burnt, maybe you can get him to send you one or go to the Thursday night meet and cruise and collect one off him Let him know if you are going to he has a disc with him though.

NissWreck (www.nisswreck.com.au) in South Australia have a yellow 1999 S2 Stagea due to arrive at the end of June, not sure if they will seperate the ECU but it could be worth a try! Give them a call.

How are you going to tune? Just interested to see what everyone is looking at doing to the ECU to achieve better fuel efficiency.

I agree, it's extremely deceptive and I'm sure it will catch more people up if they don't do the research before initiating the purchase process. Do these places want to be taken to court or what?

I didn't play around with the steering wheel but mine was flashing too. If you look for the thread I added my problem too there is a reset solution provided by iamhe77 that stopped the light flashing, for a while It was fine for a few weeks and then flashed again, Nissan just checked the error code and cleared it, so I don't know what it was but it hasn't come back on yet. Take it to a good Nissan dealer (i.e. one who will touch imports) and get a consult check done on it, they will be able to solve the issue but it might cost you an arm and a leg http://www.skylinesaustralia.com/forums/Ai...l&hl=airbag

Andy, Just out of interested what is the price and what colour(s) are they available in?

Jetwreck (Craig) confirmed this the other night, there is really no other option for a different turbo, the space is way too cramped and the location they are runs so hot. It took several hours to get the turbo out and even more of that time to get it back in! That is how fiddly the spot where it is located is to get to. I think high-flow is the best option due to the logistics, Craig went for the Garrett Ball Bearings type high-flow (shortened the length of the turbo) but I'm leaning more towards the bushes option of high-flow.

I don't want to know, but just do it quietly whoever it is! Yeah, I think you better go pick it up yourself Iain, I'm not getting caught in no triangle!

Judging from the sticker on the 2nd ECU, it's a VQ25DE not a VQ25DET From what we have seen so far the VQ25DET ECU's are printed on not stickers.

Have you got your bloody "Will F*@k for parts" shirt on again?

Maybe it's got some extra's you don't know about, the add-ons you know about may give it a little more pulling power but you never know what other hidden goodies you might have I'll have to drive up and have a squiz What are you doing later this week?
