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 :)

      I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly.

      find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank.
