Hi Anthony, looks like you are in for a great build. It looks like you have everything sorted, the GT3076r with 0.82 rear is generally considered the best street setup on this forum. Dump looks great. I hate to say it and only will as the rest of your setup looks excellent, you are doing yourself a bit of a disservice with that manifold. the laminar flow will be interrupted with the adaptor plate which is pretty weak considering you have gone to the effort of a port and polish. do your setup justice and get a manifold that has a T3 flange (pref not split pulse design). are you running nistune with an R32 ECU? tell us a bit more about the rest of your setup, looks like its going to be awesome.

hi Daniel glad to hear the turbo is going to be good - I didnt want insane power - just a punchier turbo.

As for the manifold I looked all over for a T3 top mount manifold but couldn't get one except for a cheap one off ebay which I didn't want to do. I dont think the flow of air will be disrupted that much will it? The guys welding the T3 smoothed it off inside and tidied it up. Am I really going to disrupt its flow that much? I mean are we talking loss of 100bhp or something?

The rest of the car is basically a 25 rebuild bored out...

wiseco 87mm pistons

rb26 nur spec conrods

calico bearings

arp head bolts

cometic head gasket

arc fmic

mocal 19 row oil cooler

new oil pump

new water pump

hks cambelt kit with tensioners

hks silent power exhaust

r32 gtr clutch

gtr fuel pump

so its got a few toys under the hood.

I'm also thinking about a rebuilt gtr top end for 8000rpm but wanna do this turbo first and see how it goes. At the moment I've got a heap of issues, a scattered timing signal (getting a new grounding kit for the engine). My splitfire coilpacks have packed in. I have to sort out my front suspension. Just a few things to deal with on top of the turbo lol!

SSeater - sorry mate I seem to have hijacked this thread with updates on my own progress... which so far isn't going anywhere :P

I'll post up my updates on another thread and add a link to this site when I finally get a chance to tackle my own! Great pics on your car tho - thanks for sharing!

On a r33 s2 gtst can u still use the standard intercooler pipe if u put the gt3076R??? Or does it hit the piping hit the top of the turbo?

Can anyway please help me out as I have a return flow blitz cooler n want to put a gt3076R but not sure if it will fit n work well with all the piping etc...

Thanks heaps

Fits fine mate. I have a 3076r with a return flow cooler. Just need a 90 degree elbow off the turbo and possibly a short pipe to extend the piping to the standard intercooler piping.

what size elbow would i need? 3in? what size is the stand intercooler piping?

thanks heaps!

outlet is 2.5" on compressor cover and im assuming your intercooler piping is 2.5" aswell so just need a 2.5" 90 degree silicon bend

hey guys thought I'd update...

my car is currently running and pottering to work and back. Its running a base fuel/ign map which was supplied to me by a Martin Battye over here who is an engine management specialist. He really knows his stuff and the car is purring up n down the motorway to work and back although its quite a bit rich but I'd rather that and a few extra pennies on fuel than a borked engine!

I cant boot it yet unfortunately as I still need to get it mapped but I've got the Link G4 ecu in the car so its just a matter of time. Need to install the boost controller and some other little bits like a new fuel pump (walbro255 which I know wont make me huge power but they're a good priced hard working fuel pump so I'm sticking with that for now).

here's a shot of my engine bay...

p1040099.jpg

also some videos - first fire up and me doing a bit of ghetto dyno lol...

first fire up...

second start...

ghetto dyno vid01

(turbo comes into effect on this one albeit lightly)

sorry about the video quality but it gives you an idea - you can hear the difference in fueling/ign from the first vid to the last. The car is currently idling a touch high - about 1400rpm and I've checked all boost leaks so I can only imagine its still sitting in the warm up table as I have an oil cooler and a nismo thermostat so water and oil temps aren't getting very high. Might have to put a new oem thermostat in tbh not sure.

anyhow my thread on skylineowners.com has tonnes of info and pics and chattering regarding various parts of this swap. I've never done this before so to be able to sit in traffic knowing the car I'm in isn't a mr finance and eventually it'll be a car I mapped myself is quite cool I think and its what makes all this kind of thing worth it ;)

haha i like your 'dyno' idea!

actually a half decent backyard way of applying a bit of load, would work well to adjust things to limp to the tuners! :(

thats exactly what this allowed me to do :) with enough handbrake or just normal brake I could get the car up a few psi in 4th gear. I shouldn't admit this but at one point I looked down and the car was doing 110mph in 4th gear which I shat myself about when the thought that there is the possibility it could jump off the stands so I backed right off lol ;) That said there was little vibration and it seemed to be very stable. Get a good pair of chocks for the front wheels tho!

did a bit of full load tuning like that once on a ghetto turbo honda crx, front brakes didnt like 4th gear power runs much....

yeah it has its limits - its either that or kiss your brakes and handbrake shoes goodby heh but for at least helping to get the car running and adjusting the AFR's to get some decent cruise fueling it works well I think ;)

hey guys

I know I kinda bombed this thread a little with all of my nonsense (sorry about that) but I just wanted to show that fitting these turbos is WELL worth every effort - it truly is THE turbo for the skyline! I went with top mount in the end and external wastegate (plumbed back to downpipe). also fitted greddy gtr style plenum and a Q45 afm. The vehicle is an entirely different animal. I dropped a ferrari 599 yday through 3rd n 4th and didn't have it fully planted. I've got the car setup with the link G4 ecu which is just a phenomenal piece of kit. Martin Battye who mapped it estimates 450bhp but the way it comes in and throws you in the seat is something you never get tired of. I've had to have it setup with a low boost and high boost button which is configured through my aircon button (redundant cos aircon is removed). Its really driveable on low boost making 1bar but press the button and it hops to 1.4 bar and spools the tub up much faster. It really is insane the difference in the two settings. I've also got launch control configured which arms if your stopped and the clutch is dipped and you floor the pedal... awesome fun (tho dont use it much heh!)

so I can indeed confirm - these turbos are just amazing - if you can do it then it'll make you fall in love with your skyline all over again :)

I wrote a writeup on skylineowners.com here... there's a few little youtube vids and pics too...

my 33gtst with top mount GT3076R - mapped!

Great informative install SS#eater! My current build is based off this. Just a quick question, is the rear housing .63 or .82? And what is response like? And where did you find the studs? Im not keen on just using long bolts instead

    • 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
