Replacing Buzzing R32 Turbo With Stock R32 Turbo

I have a R32 GTS-4. The turbo has always made a wizzing/buzzing sound at high revs (4000rpm+) but still seems to boost fine. I saw a R33 turbo with 30000km on Ebay which I purchased thinking it would make a good upgrade. However on getting the Turbo I believe it auctually a R32 Turbo (16v on the casing) and it has some play in the shaft. Questions as follows. Should I install a Turbo that has play in the shaft? It spins freely and looks to be in good condition but I am no turbo expert. Any idea what the sound from my current turbo would be?

Thanks

all turbos have some sort of play

this play dissapears when the turbo is full of oil

ie.... the shaft sorta floats on the oil

although i would have someone look at the seals in case they are cooked

hope this helps

I'd send it back as it isn't what was advertised.

Also an r32 turbo is worth maybe 200 bucks, i dunno what you paid for yours but if it was more than that i'd be giving the seller a massive serve.

If you are worried about the play in the shaft i'd recommend taking it to some one who knows what they are looking at, particularly as the k's on it would be in doubt now too.

You may also want to check the size of the water banjo bolts on the turbo as this will give you an idea whether it's of an early or late model r32 and also whether it will bolt up to your car without having to replace the lines.

how long do you want to wait?

I have an r32 I am half thinking of pulling off.. and changing for an RB25 one.. if I have somebody to pay $100 for the old turbo (minus wastegate) I could maybe speed this up a little :rolleyes: .. no wine, shouldn't have hardly any shaft play (never seen past std. boost I would say)..

but that's only if you want to stick another rb20det one on there..

No I have exact same issue. I took it to Benny at Chasers Tuning (who is amazing with skylines) and he said the turbo is well and truely f*cked. The wining is the turbo spining off balance. It will hold boost but it won't be very efficient

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)

      Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.

      A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
