American dynos..... so hard to trust them.

I liked his comparison to spool and power though, power of a 6262 and spool of a 3076. That was possibly more insightful than the comparison boost curves.

Anyway nice to see a successful IW TS EFR, have been waiting to see that.

Haha - yeah it could use some more boost Simon..  I'm sorry I've not put up Motec logs in the past for those who've wanted to see. Back at the time I did a bit of comparing because I did more or

Its not an American dyno, its a Dynapack- the same as a lot of the dynos used in Oz and NZ. Tbh Oz Dyno Dynamics I trust one of the least, they seem to have a ridiculous range of results - some of which way higher than hub dynos (should see some of the sheets UK forumers post!).

So in conclusion these turbos are less reliable than magical fat burning devices shown on infomercials?

That's a pitty, I liked all the features it offered which made it sound like a simple quality upgrade. Any words from Borg Warner and Full Racing regarding these failures?

John.. since you have the pitch forks and the torches out I'm not going to bother with entire timeline on the behind the scenes work.

I will let you know I was your biggest asset/fan over here in the states, and I have been (until your post) working with BorgWarner to make things right, and as justifiable as possible for you.

When we sent the second set of turbos we decided we would ship another set (4 and 5) on our dime with them just in case you had another failure (by that time we had seen 2 other failures on other cars). We wanted to make sure you could compete. We told you (or your shop), "here are two extras...we don't know how these are going to hold up."

Originally we told your installers or whomever purchased the manifolds from us we had only test fit them in an R34. Had you decided to jump ship at that point nobody would have been upset, since we had not had a chance to put them in an R32/33 it would have been understandable. Since you decided to forge ahead with making them fit, we felt obligated to do what we could to help. We also offered to build a second set for you that would fit your car if we could get a jig or a the set back that you had modified when the event was over to build them from.

It's unfortunate you are out the money to make these turbos work and ultimately fail, but I can assure you that the late night emails to AU and the early morning calls to BW to do what I can for you are most likely going to come to an end sooner than later. You may have vented too soon.

Lesson learned for both of us.

I can't see many more orders coming from Aus/NZ (Not that we make up a large proportion of sales) :no:

I am reading that those that have been on the waiting list in the UK are starting to get their turbos delivered (8374). Supply is talked of improving around April.

Anyone who has their turbo on back order hearing anything along these lines. I need to sort software for my Pectel ECU and then hoping to get one of these

I have 1 x BIB EFR6258 for sale in the For Sale Section if anyone is interested.

http://www.skylinesaustralia.com/forums/topic/387782-efr-6258-turbo/

Long story short I ended up with 3 when obviously I only need 2.

It's the latest generation so should be the goods!

Interested in trying this on the little 2L Sierra. I have done a search for a some results in single forms and nothing. They are pretty small wheels but seem to be rated similar to a TD06...would they make 250rwkws at 20psi on a 2L ?

Roy,

Two of these way outperformed two x -10's on my RB (which are similar in spec to GTRS)

If GTRS is the turbo of choice for your Sierra then I'd have to say the 6258 would be better again.

Progress. Manifold is done, lines are routed, rest of the pipework is off to a good start.

I stupidly didn't take any pictures of the merge collector, but it really is a thing of beauty. Low mount wasn't really an option, sits out about a 1-1.5 inches further out from the head than normal, and about 4 inches forward of the standard position. Worlds ugliest turbo sitting high and proud. :cool:

Clearances are uh... Tight.

All work was done by Andrew at AM Performance, it took him a couple tries to get to a point where he was happy with it, and I think he's done an awesome job of it. Heaps looking forward to getting it tuned.

that manifold is a beaty Dave, Id love to get a hold of one like that!

eat_me, borg warner is a very well known auto manufacturer... while these new turbos have had a rough start it will far from tarnish the reputation of the company as a whole.

lol sorry mate, didnt mean to sound harsh haha :cheers:

truth is BW have been putting turbos and gearboxes amongst other things in OEM cars for more years than most of us have existed.

they know what they are doing, and in time they will correct all their bugs in the EFR process and these will come into their own :)

      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.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      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).
