Hi all, picked up our 01 m35 last weekend.While we love the car for its size(have kids) and looks, have had a few issues stopping me from seeing what the car is really like(if you know what i mean).

Firstly the exhaust had a blockage and a leak so had the 4 tonne boat anchor taken out and replaced. But the turbo would appear to be having issues,it whistles quite loudly(i am comparing this to my subaru i just got out of)but also sounds like it has a slight leak.My mechanic checked it out and it has no leaks so this week he is going to check the turbo,seems to think that the compressor is rubbing on the housing (i think thats what he said lol) has anyone had to deal with this before any help would be appreciated.

Anyway great forum with heaps of info

this is her, i will give it a good clean and polish this weekend

Mine is the same with the whistle. I was told it was a sign the turbo was out of balance, but all of them seem to be like that.

I think it's just inevitable that you'll have to replace the turbo, but the whistle isn't automatically the sign.

Oh and exhaust out is great, just make sure you do the dump pipe too! There are a few options now depending where you are. Scotty on here does them, and AM Performance in Adelaide do them. These seem to be the proven options.

Congrats on the new purchase, looks good.:thumbsup:

The turbo on these is quite noisy anyway, so you may not necesssarily have an issue, but it might be worth getting your mechanic to check out the oil feed banjo bolt to the turbo, while he's poking around; to check for blockage. If you've freed up a blocked exhaust; you're probably getting proper boost now, hence the extra noise.

My turbo has been noisy since I bought it, and 45000km later still going strong; not any noisier, but I did pull the banjo out and drill it to 2mm.

Best of luck, and enjoy the new toy.

Cheers, Dale

I have a stock turbo here thats nearly silent so the noise could be either the front wheel rubbing (turbo is flogged) or usually its the rear bearing on its way out (like Dale said, drill the banjo restrictor out) Dont stress, it could last years like that if it has a good oil supply.

Changeing the T3 manifold gasket with a new oem one could be a good idea too, its a pain to get in to though.

These all have a loud whistle, mine does and i have test driven loads of them with all the same load whistle, a turbo upgrade would be the way to go if you need it but these ones run fine on factory 14psi. I ripped out my factory exhust and replaced with 3'' big bore but had change the rear muff as it was just too loud for us on long trips.

As I have stated before, this is probably the main reason for the original Japanese owners got rid of their cars at auction. The repair bill for a replacement turbo fitted from nissan would cost more than the car is worth over there.

My turbo had a fairly loud whistle when I got it. I highflowed that one before it blew but the stock one I have here is nearly silent. After dissasembly all I could find wrong with my original was the rear bearing was contaminated with dirty burnt oil and exhaust particles. All you can do in this case is increase the oil supply and hope it doesn't fail soon.

Well I will pick it up from the mechanics soon an apparently the turbo is perfect and everything seems fine so I just have a noisy turbo. Just not used to it being loud after having the quiet turbo in the Subaru.So it now needs a service for new plugs and an injector clean so I'm of to a great start with the car but at least there is nothing major stuffed on it fingers crossed

When you put the foot down it boosts up then stutters like its missing,not all the time only when you give it a bit and fuel consumption is crap its used half a tank and done 170ks and that's driving like a granny. I generally get all our cars serviced not long after buying them any way plus our mechanic has only charged me for a air filter and he has had the car twice in the first week since we have had it.

Not sure how he checked it but he said its fine and I trust him he has been our mechanic for years and dealt with plenty of turbos with the rally cars he has had over the years

I'd also be looking at the O2 sensor.:thumbsup:

    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
    • The frontend wouldn't go low enough because the coilover was max low and the upper control arm would collapse into itself and potentially bottom out in the strut tower. I made a brace and cut off the kingpin and then moved the upright down 1.25" and welded. i still have to finish but this gives an idea. Now I can have a normal 3.25" of shock travel and things aren't binding. I'm also dropping the lower arm and tie rod 1.25".
