Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

Hi guys I'm new here just bought a Nissan 1989 gx skyline only done 15000 km in immaculate condition just want to know what I can do to turbo it I'm new to tho site and don't know much

Any help would be great

If you want to put a twin cam head on it read the thread in this section. If you just want to put a turbo on your current engine start by googling "+T on an RB30" - that should get you on the way.

what are you trying to achieve? for the streets its best to keep it stock low mount i think, can get well over 300kw with just a stock

manifold and a gt30, that's what ill be doing soon.

Hey guys going to pick up a series 2 vl block tomorrow for my r33, and the bloke reckons it's got stock s2 pistons with cut outs to suit the rb25head, I've tried searching but havent found anything about cutting down stock pistons, only swapping them out or decking, can this be done and I've found a good deal? Or is he talking crap to try flog it off quick. Or have a I confused myself and by cutting down he means it's been decked already?

He means the stock rb30 pistons have the valve reliefs to suit the 25 head.

As they all do.

Which you can tell by looking at the pistons there are 4 reliefs.

Due to the layout of the rb30 head.

Good luck with the build.

I bought this turbo (only oil cooled, not water cooled) (with an internal wastewater) for my r32 gtst skyline, with rb30 bottom end & rb25 head. My mechanic reckons its no good has a million different reasons as to why which to me this makes no sense. Im not to sure what this turbo as the guy that i bought it off had it for an upgrade was unsure what it was off.

I Googled all the numbers on the back which said it was for a 9.0L scania diesel.

Still school holidays still on so not sure if 9 year old buuuuuuuuuuuuuutttt........ I agree with mr mechanic, piss it off and get a turbo that is actually designed for a 3.0L PETROL engine as opposed to a 9.0L DIESEL engine! Buy a ching lingalong copy turbo off ebay and you'll be a lot better off.

I understand where your coming from with the lag n that. I took the turbo, manifold n wastegate to another mechanic today, whos got an r32 and owned a few skylines, and he said his mate has one with a bigger rear compressor wheel and he says its really good, it just depends on what you want out of the car,, and im jist looking for as much power as i can get. I just want to hear what everyones opinion that way i can keep my options over... But thanks for the advice..

Do some research on here first BEFORE you buy anything otherwise you'll just be wasting money. Check the other RB30 threads on turbos and see what power people are making with certain turbos and choose that way, A mate of a mate offloading a turbo is a bit risky unless you know what it is. When you say bigger compressor wheel, bigger than what?

How about we find out what the turbo is before we doom it to the recycling bin ?

Post up pics of it and the link to where you found out its for a scania

The Holset HX35 turbo is what comes on my truck but has produced good results on RB25s

What is the part number, with a stroke of luck its a GT3782

OK, been chasing a RB30 twin cam belt while abroad, and had a bad time, i worked out that Audi / VW do have the 153 tooth belt for the 1.8t engine as stated early in this thread but there was no part number!

so the part number is...

058109119c
Dayco 94407 belt from Audi / VW. should get it tomorrow.

grind/ face off the old rb30 number and engrave/ stamp a 25 number off a broken 25 

technically you cant legally register a rb30 as its an older engine in a newer body 

Actually there's no technical or legal reason why you can't.

There is no Law against an older engine in a newer car. What the law does state is that the emissions must meet that of the newest items, either the car, or the engine.

Therefore if you drop all the RB25 emissions gear on, the setup is fine.

Depending on state you may need an engineers cert for the capacity increase.

      I'll snap up some photos when I'm back home, in the office today meeting my "in the office" quota. Have 2x Teams calls scheduled in, office culture they reckon.   I've never owned a proper off the shelf sub, I've always made or modified broken ones with Jaycar plate amps and/or car subwoofer drivers. The current (and broken) subwoofer has a proper home driver in it, Dayton driver, thos one https://www.daytonaudio.com/product/118/rss265hf-4-10-reference-hf-subwoofer-4-ohm FS of 25Hz, which is low but not low enough. Yeah, I think they were brought out to the market to compete with SVS. I would love a SVS PB-3000 but they're not cheap, especially after their price hike. From reviews online, it does look like the Tonewinner D6000 would destroy and with good amount of money saved too.

      yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.
