i know some guys have used this turbo on there rb20 ie megala,well i just got mine today ive had a quick look at it and its definately bigger just looking at it, but 1 of the oil/water lines have like a flange with 2 bolts and a hole in the middle, but on the rb20 turbo its just a threaded hole,just wondering how u guys got around this, did u just drill and tap it to the same size as the rb20 so u could use the same fitting? or what. Also what did u do about the wastegate actuator rod that connects it to the wastegate flap,it looks like it goes into the actual dump pipe, and 1 other thing,the outlet on the turbo looks very small with VERY thick sides,has any1 got out the die grinder and done some porting themselves or even cut off the end and get it rewelded,

thanks guys,also i can get 1 more if some1 is interested for under $250 in melbourne dont know the condition though

sorry this post is long :mad:

The easiest way is to use high pressure fuel hose with three hose clamps on each end to make sure it doesn't come off.

When you cut the metal line(s) from the turbo make sure you remove it first and remove all of the rough edges, blow it out with compressed air to ensure there are no metal filings.

They wouldn't go to well if you get metal filings in the oil side of the turbo.

Remember the BB and non-BB turbo's require a different amount of oil there for it wouldn't be to good if you adapted a rb20BB oil in on the non-bb vg30 turbo you have.

What you've got there is a T3 from a VL turbo (RB30ET) , not VG30.....

Yeh, VG30ET (Z31) and RB30ET turbs are T3's and almost identical, but VG30DET is more like RB2x turbos in design (but bigger), ie doesn't have the 2 bolt oil line attachment, etc....

I'm starting to clean up the vg30 that I have and it appears that all of the water oil feed lines are the same size etc.

All I need to do is undo the bolt and insert the metal line from the RB20 one.

I might even use the Wastegate actuator from the RB20 if i can as it is has the right bends for the ange of the compressor cover.

its done just gotta put it on now,my only prob is that i gotta still use the dump pipe i got with it,but by the looks its really big and its got a 3" out on the pipe aswell,took me about 2 hrs but i made a new fitting,and used the oil lines from the vg 30,cut the steel lines and im joining them with the lines to the engine,thanks heaps for that idea,works really well, i also finished my intake side of my cooler pipeing,sooo tomorrow itll be going again with new turbo and cooler :D

I've got one of the BB ones it turns out.

And guess what.. All of the origional banjo fittings screwed straight in.

I still used the bolt (with the restrictor in it) from the VG30 but.

No cutting.. Straight in. :D

Only problem is the compressor out is obviously different which I poped down to profix today and they said yer.. $10 or 15 bucks for bit of piping bent and flared out to the size of the stock piping. ;)

Should be up and running tomorrow.

Also Use your RB20DET Wastegate actuator and loosen off the bolts on the back of the compressor housing a little and then spin the compressor housing so the wastegate actuator lines up nicely and then the compressor out will miss the manifold when bolting it in.

Please make sure you use lots of hose clamps.. Wouldn't want it coming loose..

Here's a pic.

arrrrh ok cool,the turbo i have is kinda different but it all worked,only had to make 1 fitting,also ive already changed the wastegate actuator as the one that cam with it was stuffed, also i noticed yourve got the 3 bolt outlet pipe like the rb20,where as ive got just an outlet to put the rubber hose straight on

now i just gotta either make or find the flange from the dumppipe as its different to mine,but no exaust shops are open :D

gotta wait till monday soo ill just drive it with no exaust on lol

Macka..... ;) 2540 was a different bolt up. :D

This damn VG30 is stuffed.

:D

Started the car and there was a really nice wirring noise.

As I rose the rev's slowly the wirring got louder.

I even cranked the car over to pump the oil through the turbo before i started it to make sure it didn't spin on dry bearings.

Oh well.... Back it goes. Hopefully.

I new there wasn't something quite right with this turbo.

Well if Meggala Is watching.

..............

You told me so but did I listen.

Now I need to pull the damn thing off again.

I am really starting to think about a highflow of the std unit as it is blowing a crap load through the bov and the std turbo has heaps of end float also.

    • Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.
    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
