Changing R33 GTR Turbos - advice

[Links]

All,

I've picked up a set of GT2860-7's for my R33 GTR and looking at swapping them out myself (yes have read through the pleasure that this will be).

Am after some advice on the following:

• Any specific tools someone would recommend I get before starting it off to avoid having to do the inevitable trip to supercheap etc while mid-flight...
• What do people recommend from a gasket / studs etc kit - seen that Kudo's have a complete one however looking for advice on what's really required - http://www.kudosmotorsports.com/catalog/turbocharger-install-suit-nissan-skyline-stagea-wgnc34-260rs-rb26dett-p-5.html
• Oil restrictor - is it required or not? Have read multiple threads however not clear still - some say yes.. some say no..

Thanks in advance.

Curved scanners are bloody helpful! Help you get to some of the turbo to manifold bolts that are hiding around corners. 

Uni joint sockets are a must. 

A couple of things to do while you’re at it are replace your manifold studs and fit braided lines. Piss the hard lines off. Makes life soooo much easier for refitting and removing next time. 

Good luck!

Great - thanks for that, exactly what I wanted to know.

Will look at getting the stud kit then and replace those and save having to do it again. Re: Braided lines - good thoughts - something like this I assume - https://www.ebay.com/c/651282471

Cheers - might need it, or just some patience!

Also get plenty of wd40 etc on the studs and hard lines for a couple of days before. 

The biggest (unexpected) thing is normally studs failing and snapping, so if you can have them freed up as possible before you start it will really help. Once a stud has given out you might be lucky and able to get it off with whatever remains, or you might have to drill and easi out it which is where the job turns into a disaster. Heat /blow torch can really help if you don't like how it feels when you are undoing it.

The hard lines often won't free up from the banjo properly so they turn with it an eventually snap, so like Ewan said aftermarket braided lines handy means you don't have to worry about that.

Good luck mate!

Thanks Duncan - yeah the studs snapping is on my mind - good advice to get some WD40 on it for a few days leading into it and just taking it easy. Will factor that in definitely.

Sounds like braided lines are the way to go.

Thanks - the good luck's piling in...

Don't use WD40, ATF + acetone in a 50/50 mix is a lot better and ATF is pretty common stuff.

For farks sake mate, WD40, CRC 5.56 ect is fine in a pressurised can so you can spray it, and what MOST mechanics who work on these jobs to free up the nuts and bolts will use in the real world.

I'm just cheap, I have a bottle of ATF in the garage and some acetone.

This. I still remember the nut in the corner of the rear turbo. Probably took me 1/2 day to figure out how to get it off. In the end i bought a small spanner(i think 12?) and grinded the corners. Also, not a big thing, but lining up the water/oil lines was a bit of a pita as well.

If you have friends it would def help. Also look at replacing all the gaskets and washers at the same time. Personally, if i was doing that again, I'd rather pay someone!!! Its a fkn pita, esp in a tiny garage on axle stand only!

The best advice anyone can give is if you don’t have genuine mechanical experience, get someone who does

Feel free to ignore.

Replace it with a single twin scroll turbo, because you're going to eventually put a single on it.

I used to argue this. Now I don't and I haven't even driven it yet!!

The simplicity of the single is a definite advantage. 

[Dose Pipe Sutututu]

I've been saying it for years, and over and over again. Funny all of the twin gay huggers have mostly moved to a modern, single twin scroll setup.

Stubbs are great but if you don't have them already get the two different types of curly spanners. Not useful till you need them then they become life saving!

[r32-25t]

To do this job I’ve got s shaped spanners, crows feet, 1/4, 3/8 and 1/2 drive socket sets with lots of various length extensions, rattle gun, ratchet ring spanners, normal spanners, offset spanners and the list goes on. 
 

I have doing this job down to art now but I was a mechanic and am lucky enough to have a very extensive range of tools at my disposal 

I’ve also seen more then my fair share of people who have f**ked this job attempting it 

[Shoota_77]

Perfect, sounds like you’ve got all the right stuff!

Doing a rough count in my head I have 14 sets of different spanners, possibly more. I feel I may have a sickness...

2 sets of cheap metric I use most of the time

1 set of long shank

1 set metric stubby

1 set metric stubby ratchetting

1 set normal length ratcheting

1 set metric double ring

1 set imperial double ring

1 set imperial standard spanners

1 set metric S spanners

1 set metric C spanners

1 set crows foot spanners

1 set I keep in my Ute

plus I think there’s a set of stubby imperial spanners out there somewhere!

Most of them are cheap shit apart from a few.  I sold my snap on stuff years ago when I got home from the tools and needed money to fund a stupid lifestyle....

This wasn’t a dick swinging contest but would be curious if anyone had any more than that for a non commercial setup! ?

Has good spanners.  Uses the cheap stuff so doesnt ruin his good spanners....?

[KiwiRS4T]

I have SK Wayne stuff I bought as an apprentice. All in perfect condition apart from the odd piece I have lost, Sadly its not available any more.
