My car is at the mechanics getting a major service & an R33 SII turbo fitted. He just called to tell me there is problems with waterlines. He said i will need parts from a wrecker which is not good as most state these turbos as a 'bolt on fit'.

If anyone who has performed this swap can point out the oil or water lines that dont fit & how they got around the problem it would be greatly appreciated.

I will check it out at lunch and edit the post once i have had a good look at the problem... i really dont want to hunt around in wreckers unless absolutely necessary

It is a straight fit...i bolted on a r34 turbo myself (not r33) and everything was still a straight fit!

It was new so didnt come with any water/oil lines, all the original connections

bolted up, i think one of the water lines i loosened one support to allow me a bit more slack but it all lined and bolted on.

All i bought was an oil gasket for the oil drain.....

100% without a doubt its a bolt on job for the oil and water lines. The compressor outlet pipe you need the r33/r34 one though. (usually comes with turbo).

well i just got back from the mechanics & apparently some skyline turbos have different diameter banjo fittings as the ones on the new turbo dont fit through the original lines!!

new turbo is the one 45v2 on the compressor & is currently bolted onto the car but the lines will have to be fitted with the bigger banjo ends to finish the job.

lesson: check the banjo fittings before doing this swap.

yep thats the one. bloody waterlines.at least i'm not the only one i spose (means i'm not swapping to an unknown turbo).

most say that they have had no probs. it must have been for a certain year/model. maybe the early r32s like mine had the older (smaller) size banjo fittings.

looks like i'll be visiting some wreckers... :)

I've done the swap too with no probs. Mid 92 GTSt to a GCG highflow, 45v1 on the comp cover if memory serves. Not that its any help now :)

But i did do a turbo swap on my S4 rx7 and Mazda had changed the oil banjo bolt sizes mid run, the bastards.

hmmm... now the tedious task of ringing around wreckers for the pipework with larger banjo's. if its a SII problem that makes it more difficult again as wreckers are less likely to let go of small parts on newer engines

according to the boys at just jap (see the sponsor at the top) the turbos changed during the r32 not between 31 & 32!!

apparently the first if the r32's had a similar turbs to the red top rb20, this is why some people have had probs and others haven't.

lesson: early 32s = not bolt on fit

later 32s = bolt on fit

will add to this if there are any further differences (i'm really hoping not!!)

yep thats what the just jap lads said. probably why my car felt a little laggy than others i've been in. it seems the popular belief is that the bb's came in when the R32 did - not during the R32 model run.

but, as it turns out, not all R32's ran ball bearing turbos.

at least the SII turbs should be a decesnt improvement over the old one!

If you're going from a non bb turbo to a bb turbo make sure there is a restictor in the oil line or it'll blow smoke like a biatch.

The stock oil line off an rb20 with a bb turbo will have it in but a non bb wont.

I put a RB25 BB turbo on my old NICS RB20 about 5 years ago using the RB20 oil and water lines. I just bored out the banjo fittings until they fitted. I used this turbo for over a year and never had a smoke problem. I ran 13psi and found that the turbo spooled up quickly and the car produced power all the way to the red line. It was a nice improvement.

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
