Hi guys, Not happy at all but I think I've blown a turbo or turbo's. Engine isfresh. Rebuilt N1 spec motor with 4000km on it. Has Rebuilt R32 Nismo Turbo's.

Had some work done, tuned etc. Car is making 302rwkw on 18 psi. Been driving it for 2 weeks since and its been great and fine - no issues, but today I noticed a tiny bit of whit smoke under boost. I didnt think too much of it. But then earlier I drove it, and gave it a bit of a boot. As I did I heard a big bang, with a cloud of black smoke. :( = not good

Now the car doesnt boost at all. Quite undrivable... And if it hits boost, like 3000 or over. Exhaust just pours out with ALOT of white smoke. :( From all the reading ive done, means a blown turbo or turbo seal. Does this sound like the turbo's have gone?

I suppose now I have the option of getting them rebuilt, or buying some new Garrett 2860's or something etc. What do people recommend. $2-3k is probably about my budget.

Is this the right part number?

A pair of -7s will probably be about $400 cheaper than -9s once you take into account new actuators. From the rb26 dyno sticky they seem identical to at least 300kw, but -9s would work a bit better if you push higher.

You should be able to get them locally for that sort of money - check out the Traders section.

Put it this way - the bad news is you've blown turbo(s).

The good news is, they were crap to begin with so you can put on something much better.

The replacement option for response (-9s or -7s) will make just as much power as your Nismo turbos, but will be noticeably more responsive.

Rebuilding to start off with was kinda a waste of money unfortunately.

Thanks for the advice. -7's sound like the go to still have a more responsive 300awkw. The nismo turbos were already freshly rebuilt when I got the car. I guess they couldn't handle 19psi? :(

Any idea on what $$ for labour on a full turbo swap?

This seems okay. I dont wanna sound dumb but what are the actuators used for?

Controlling boost pressure.

As for turbo swap, give a few places a call.

If they tell you they need to take the engine out, hang up... After you tell them they're morons!

I spose it comes with experience. I don't have it but know people that can have them out and in within 5 hours.

Also, get Deano to call or PM me!

Is it worth the lag and just going to 300kw? I don't think so. Besides its been discussed to death. -7 300kw beats -5 300kw down the quarter. Don't know where I saw it, but one of the -5 vs -7 threads yielded that.

What kind of sick individual buys -5's to make 300Kw, unless they are planning to go further at a later date ?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
