the new and the old

ok once the turbo is off you must lock to nuts together and remove the stud becareful not to break them.i do about 1/4 turn then back the other way then go 1/4 more so like 2steps forward 1 step back ..helps to free them up....

test fitting.. note manifold clearance ....water and oil lines check it all looks good and where it should be:)

post-28208-1233572242_thumb.jpg

you can see here that the comp housing fouls the manifold so yo must run a 10 mm spacer..hence removing the studs for longer ones..

ok this is the new dump flange, i cut the wastegate pipe hole myself ...holesaw nuthing special...remember cutting compound ...

I placd an order for a four bolt turbine housing and external wastegate but my order got cancelled. I tihnk it would have made it easier but I think the GT3076R is the ideal turbo for a stock RB25DET. I may go down the road again and purchase one and have everything done. Nice work you're doing there.

right now its the standard one got a z32 ready to go on very soon..

i didnt think about running the afm in the cooler pipeing....is this common.?

hmmm:)

so much rain here cant get the car tuned really shitting me.. want to reap the benifits ...dammit....

i've got a z32 afm as well, but i really want to upgrade to a gt3076r with the 4" anti surge port comp cover, i didn't realise the whole afm dilemma until i saw it here.

oops.

i've seen the afm in intercooler piping done a lot in VL turbos

it makes sense to have it closer to the throttle body, and it would measure the proper density of air as well (if its placed after the intercooler)

but im just making suggestions, speak to your tuner and see what he says

otherwise, maybe go for a d-jetro setup?

not going d jetro just got a norm pfc ....q45 solves any restriction proplems....will eventually get 1... just brought a z32 ....new to....crap..lol

the turbo sounds awesome...i have just been crusing around only boosting to 5>6 psi...standard ecu still in it aswell so dont want to kill my motor

i spools up real quick...cant wait for my tune 555cc nismo inj and z32 to go on soon.. got water meth injection on it now too. not runnig though saving the meth i have for the tune..waiting for a few drums to arive...:thumbsup:

Nice write up mate, im also going to be installing a 3076r very soon, but i got the externally gated version with avo rear, so i will be needing custom piping to be welded up.. ive been quoted around $2000 for the installation and piping, thats including relocating the top intake piping that goes over the tappet covers because i got a top mount manifold. does this sound a bit too dear?

not really if thats the turbo installed new dump and new intake pipeing..id say thats fairly good price.... my oil water lines were nearly 400 bucks alone....do you like the d.i.y oil catch can....silicon hose 2 spray paint lids soem hose clamps a filter and you got a catch can....

hi there

my name is anthony and I am a member of skylineowners.com in the uk.

I have a fairly grunty Rb25det at the moment - it has a fully forged engine but the turbo isn't the punchiest - its a td05 18g and it only makes a total of about 380bhp. Its currently making a smooth 340bhp but I have been looking to get 500bhp if possible. However I wasn't sure what to look for and have just found your thread on fitting the gt3076 which looks perfect and proper beefy under the hood lol! I fancy having a go at this myself but I have some questions.

1 Can you but the 10mm spacer flange to get the turbo away from the manifold? I saw that you cut your own but I dont have any facilities to do that :)

2 Would I need one with an internal wastegate penny as I've seen a couple for sale that dont have that!

3 Do I need a gt3076 with a T4 flange or a T3 one? I'm a little lost with that stuff :D

4 I have a Z32 afm - is it much fuss to fit between the induction filter and the pipework?

I found this turbo on ebay from perth australia which I've been considering - is this what I would be after?

item number: 170313773271

sorry for all the pestering questions but I would really like to hit the 500bhp mark and I know the engine would happily take it (wiseco 87mm pistons, rb26 nur spec conrods, arp head bolts and numerous other goodies). not many people have fitted one of these over here in the uk but I'd like to have a go :)

hi anthony

1. you can buy a spacer from SAU traders or turbo shops.

2. internal wastegate unless you want to get involved in changing to an external wastegate (which means either new manifold or you need to modify the turbine housing to fit an external wastegate off it).

3. T3 flange

4. Z32 is a straight fit but your ECU (ie. aftermarket) will need to support the change.

hi Wolverine thanks for your answers :thumbsup:

The Z32 is already under my car and my oem ecu is mapped to use it - the tuner used Nistune and was at Rising Sun Performance in the uk (dunno if you guys have heard of them over there?) Anyhow I'm pretty sure he'd be able to map the car using the bigger gt3076

so I'm guessing the standard downpipe is enough for the turbo to work with and is a direct fit is that correct, or will that need uprating too?

I have been told I will need to uprate the injectors - at present I'm running Daetchwerx 550cc injectors which I'm sure (at a push) will run 500bhp or in that higher 400 range certainly which would be enugh for me. I have also been told my gtr clutch would need uprating. Any of you guys confirm that stuff?

you will need a new downpipe if you get a garrett turbine housing (which i would recommend) there are some GT3071's and GT3076's shoehorned into nissan turbine housings but i believe you will get a lesser result this way. there is a good thread on what constitutes the best version in forced induction at the moment.

the 550cc injectors will be fine.

clutch will only need replacing IF it lets go which is more a function of how you treat it/use it.

Nistune will be fine.

wolverine - thanks again - how can I tell if it is a garrett housing - is it literally stamped with garrett? I'm guessing the nissan/shoehorned would have nissan on it if it was the lesser version?

downpipe - are there specific types that mate up with the gt3076 and onto the other side of your exhaust easily?

clutch is never pushed hard - I dont even launch hard as I believe this is worst way to kill a clutch but if it gave out I'd upgrade happily anyways. not a tough job to put another in anyways. even lifted out the gearbox on my own shoulder lol!

good stuff about the injectors n nistune - I can get rsp to do the remap/retune again :thumbsup:

worp3d - I dont know too much about what he's done in the past but I do know the guys level of knowledge at rsp is amazing and they're a really friendly bunch :laugh:

anthony - try tweakit.net

they have a 3076r package, which includes, turbo, lines, dump pipe and spacer and flange. Shipping to the uk will probably set you back an arm and a leg, but it might just be what your looking for.

copy-n-pasted from their website:

Includes:

1x Garrett GT3076R RB20DET-RB25DET Turbocharger, complete with internal Wastegate and actuator.

Fitting Kit Includes: Oil and water lines, Gaskets, Spacer, Studs, Nuts and Silicone Elbow for intake.

Optional: Mild Steel or Stainless Steel Dump Pipe (both have separate wastegate pipe blending in three quarters down the dump pipe.

The Exhaust Housing has the 5-Bolt Garrett dump pipe flange (Rather than the 6-Bolt Nissan dump pipe flange), so if you are fitting this turbo to a Skyline (R32/R33/R34), then the optional Mild or Stainless Steel Dump pipe is highly recommended.

$2,460.00AUD (inc GST) AU

$2,236.36AUD(ex GST) AU

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
