Hey guys

so ive been informed by my tuner that my GT3071R is on its way out... and he has highly recommended that I buy another turbo because my current one will not last longer than a few weeks... He doesnt believe (and I agree) that we should rebuild the current one as it will not be feasible

So I'm now after an internally gated GT3076 (figured might aswell try to get some more power if im gonna spend all that money)

tried to do a search on here but im getting like 24 pages of results so yeah

since I bought my turbo 2nd hand off a guy on SAU, I have no clue where to shop for turbos

besides nengun and ebay the only place I've found is www.tweakit.net

I could ring around turbo shops like GCG and all that, but does any one have any websites that I can go to compare prices?

Cheers

U

If your turbos is still making boost without too much noise its lot cheaper to just get it rebuild with a new set of Garrett bearing kit which will cost only $660 assume your stock wheels and housings are in ok condition.

We will email you a inspection report before starting any work. So you know what you will be paying and why your turbo has failed.

Can vouch for Horsepowerinabox http://www.horsepowerinabox.com/, established company been around for ages, plenty of their turbos in some great machines.

I prefer to buy from a company thats been around for a while, last thing you want is something with an ebay knockoff in it.

If you want to rebuild your turbo I also reccomend GCG http://gcg.com.au/

Rebuilds are expensive unless it's just bearings is that right? I was under the impression ball bearing turbos weren't worth doing anything to once they start to get play. It's usually cheaper to just buy another one.

Also a GT3076R internally gated can be done. To open it up properly an exernal gate on a high mount would be better though. What turbo manifold you running? What's the size of the engine? RB20 I would recommend the 0.63 A/R @ 21 PSI but an RB25 could take the 0.82 A/R @ 24 PSI with the extra displacement.

As for turbo purchases these sites listed already are the ones I know of unless you go on another forum hunt.

^ Nope.

It's 100% cheaper to rebuild. The Garrett cartridge itself is around $1000.

Add in balancing and refit, you're saving at least $500. You get to use toye housings, and wheels again.

Send it to GCG for the rebuild, they have the best equipment in the country.

They will also be able to provide reasons why the turbo has become tired/worn in the first place - and IMO this is the [/b]most important thing to know.[/b]

There is no reason a ball bearing turbo should fail without a ridiculous amount of KM's on it, or extremely poor car servicing routine.

wow thanks for the reply guys, will definately enquire about rebuilding the turbo...

when i gave it to the tuner, it was making boost just fine, but was just taking forever to hit full boost (was getting full bost at like 5500RPM, something to do with a leak near the wastegate) so when he took it out to get it bushed, he got a "turbo expert" to look at it and he said it was about to go...

so Im gonna have to stop by and see whats actually wrong it it.

its a GT3071R, and it made 260rwkw

stupid question, but can I hiflow it or getting bigger internals for the turbo...

wanted to hit my goal of 275rwkw (i know its only a number but I feel like I didnt meet my objective)... might as well give it a crack while the turbo is out

GCG are probably the best ppl to talk to about this right...

I'll assume it's an RB25DET according to your pic. If so you sohuld be able to hit over that figure with step 1 cams (290 RWKW or so?). The GT3071R is a great turbo for response and power and work better with cams. Get some step 1 cams so you keep VCT too :P. Get a set like these:

http://www.nengun.com/hks/camshafts-nissan

They drop right in, keeping VCT and no need to upgrade valve springs unlike the larger step 1s such as JUN or Tomei. Get a Rocker Arm Stopper kit just in case for another $80 and you're set.

Good luck.

get a dyno sheet to read 275rwkw mate, same thing. As honestly to get hung up on a number is stupid.

One dyno will say 260, the next will say 275. So who cares?

Rebuild it as is, or be prepared to hurt response by going to something bigger.

As for CAMS - they will not magically get you to 290rwkw, so i totally disagree with the post above this.

I made 370rwkw through factory RB25 CAMS. Same as Guilt-Toy has done with a 25/30 and a GT35.

They are not a problem.

Cam haters. ;)

I'm not sure who thinks they magically add power........ :D

I reckon there is about 10-15kw going to 256 deg poncams but whether it is worth it is an entirely different question.

I would rebuild the turbo, re-tune and be happy or spend the extra money on buying a GT3076 if you want a bigger number.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
