Hi all!   I've not really been active on this forum for some time and although I lurk in to read bits and pieces of interest I don't really think of this as a forum I'm part of but I once was and I di

well nice to meet you then! I think you know who I am?! I know Jon, Geoff, Raffi and Brock at BW but those are the only guys I've really worked with so far (and they have all been good to work with). You must be too important for the likes of me!

Anyway, those are just a few preliminary pics (taken in my kitchen) but I'll have some good ones later. Someone in this thread already posted some great pics of the 6258 including with the housings off etc so no need to go nuts. but I don't think anyone has really seen the manifolds for the RB26 tiwn 6258 kit up close and not fitted to the car before.

Ha ha! Nah...I'm like the crazy uncle you keep away from the rest of the world.

I just usually stay behind the scenes on most transactions, but I've been involved with a lot of the BW testing and talk with BrockStar regularly, I've been particularly impressed with the twin 62/58's thus far. (mainly because we really haven't had many of the big framed turbos) We don't have that many RB's here in the states and the twin set up we've tested out here has been very promising. (Very linear, plenty of power down low, no shuffling, quick shift recovery, etc)

What size injectors and how much fuel pump do you have going to these things? And what kind of fuel?

Nice Pics! Photos look sharp!

If I was in the States I would have got a Full-Race Manifold to go with the EFR 8374 I have coming....But it does get up there when you add the postage and Duty and GST into NZ

Very very nice - so to clarify, there will be dyno results for an EFR9180 and a twin EFR6258 setup coming soon?? Are the setups ones which the potential of these turbos might be unleashed?

Either way, :worship: and fingers crossed for some good numbers :)

well I probably personally own more GTRs than there are in the whole US!

feel free to send me the 8374 kit to try!!! :)

You know about the 9180 car I think? it's a 3L, plenty of fuel, plenty of supporting gear and running on E85. No effort spared on that car. Boost will be as much as the turbo will efficiently run. Probably around 30psi or so? unless it makes masses and masses of power in which case it'll be turned down a bit (would have to be a fair bit for that to happen though!).

the twin 6258 car is running E85 too, again plenty of flow in both injector and pump has so far made over 400kw on 2860 -5s and a bit more on the -10s with the current support systems. It has a tough 2.6L and all the supporting gear and we are hoping for 450kw or so out of the 6258s and prepared to work them hard to get it. Comparing both compressor maps and just the basic wheel specs between the 6258s and the -5s and -10s tell me the 6258s should flow as much as -10s, they will be efficient at higher boost levels than either the -5s or -10s and much less prone to surge than the -10s (due to matter size match of compressor and turbine wheel). so basically -10 power without the massive surge zone. so much nicer mid and low range and still a bit hit up top.

yep. due to help from BW and Full race with the 9180 etc we'll be giving them feedback on it's performance and I'm sure they will most likely want some of the stuff like dyno sheets to go public. though being a competition car we don't want to give too much away but I'm sure dyno sheets will be forthcoming. Same goes with the 6258 car and yes results for both will be coming fairly soon. like count the time in days or weeks. certainly won't be months as they both have deadlines.

and yep, both set-ups are ones which will allow the potential of the turbos to be unleashed. they are both full on track cars so goal is driveable, usable power and lots of it through as wide a band as possible.

fingers crossed they both make good numbers indeed! I pushed hard for EFR turbos on both these cars so if they don't work I will have to relocate to arizona and move in at full race as my house will probably get burnt down or they'll make me eat the 9180!

That would be the High Octane R34 Time Attack Car?

Did hear a while back they were looking at the 8374 or the 9180.

I do wonder if the 9180 will be too big for a Time Attack car.....But then again, Eastern Creek is a big track, I just hope they have some Aero/Downforce for that monster this year.

There is certainly just a little bit of aero going on from what i saw last week :whistling:

Some really impressive/detailed stuff, along with the rest of the car which really does leave you jaw on the ground.

After just seeing that one car, I'm spewing im working and can't make it to WTAC :(

I should get my A into G and book a flight to watch this year....Fly there, take train to the track, watch some WTAC, train back to the airport, fly home.

I love Sydney public transport....probably cheaper for me to fly to Sydney to see this, than flying to Hamilton for the V8SC's......And I live in NZ!!

I do know about the 9180 car, that's a bad ass. I expect to see BIG usable numbers out of that thing.

The 6258 car may surprise you. We saw 405kw at 19psi here on our crappy 91octane fuel. If you're going to turn the boost up and run E85 and really "work" those turbos I wouldn't be surprised if you see closer to 500-520kw. Depending on boost levels obviously and provided you have enough pump/injector. The 6258 car here in the states ran out of pump, but had 2000cc injectors. It's running the ProEfi with a flex fuel sensor, and once there is more pump installed he'll hit the dyno again with E85 and see what she'll do. (and when it's not 110º outside)

Very keen to see how this goes!

Hopefully someone does some 7064-IG-TS+SR20 as well so I dont have to be a test pilot incase they're a flop on these engines!

As soon as my 8374 arrives and I have got Sinco to make the manifold (They have tacked it together to check first that it fits with this turbo) I will have the car on the NZEFI dyno (4x4 hub dyno) and we will see what it's like on a built RB30/26, I will post results/dyno sheet when done

You'd be about the only one that does!

Whys that?

I use a multi 2 ticket that gets me on any bus, any ferry, any tram and any train within the metro area with unlimited use for the week.

Trains are seldom late, buses fill the gaps, ferries make for something to do on the weekend, so on and so forth. I should get my license back in 2019 and so far the last 3+ years without it havent been bad :whistling:

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
