It is an interesting result, falls over quite early for a cammed RB25 with a GT3076R though - wonder if there is a restriction somewhere or something. I would have expected a bit more, but I guess we have fairly few internally gated/stock manifold E85 results to work from.

I wonder where you've seen that.

The GTX3582 AR63 isn't a good choise. It produce exact the same power as a GTX3076r but, came on 500rpm later! A GTX3582 Ar 0.63 doesn't make sense because the turbine housing is the limited factor! And with a Ar 0,82 it is very much to laggy. I say that with experience, because i've had a gt3582 Ar0.82 on my Gts-t with a external screemer pipe :-) ther's nothing to 5k rpm and than "bangggg!!" funny but not very useful.

Is there nobody who ha experience with a gzx3076r on rb25det?

I have gtx3076 .82 on my rb25...

The RPM is calculated though, its usually not accurate from what I have seen, how can you know every car's ratios anyway? If you can't work it out from the graph i'm sure someone will have a guess for you, without seeing the sheet I can say it would probably come on hard around 4k.

My tune today didn't pan out, speed cut and a slipping lock up clutch ruined my chances of a good result with the 71. I will be back on the weekend with the SLD back in place hoping for 350kw.

The gtx3076r is similar in spool, if not a small margin worse, than the gt. The gtx really only comes to life once you start throwing lots of psi at it. Although.. Im sure a true twin scroll housing+manifold would bring the spool back to baseline.

Any luck with the tune Scott?

I was seeing over 300kw in 4th at speed cut which I guess was around 5000 revs. Once I wire the SLD and get rid of speed cut again I will be able to see the outcome of my fine tuning. The MAC wastegate solenoid is working a treat now, it held a flat 25psi from what I could see. I will ramp it up on the weekend during the next run.

It has external gate, AVCR , 256cams, cam gear, maybe a 50/50 ethanol blend

id be happy with near 200kw at 4000rpm with 18-20psi

Why 50/50? how far away is Warwick from you? (or is there a Caltex up there?) You will see better gains from just running United e90 with none of the cold start issues we see down here...

You should come close, perhaps around 4200 revs? That's my guess.

well im doing all this on a tight arse budget and getting impatient, some parts like the HD clutch, walbro fuel pump, and now rear muffler with silencer may fail before it reaches 300kw

So i guess for now ill have to see what happens on the dyno, im thinking even 280 would be great,

50/50 blend is another cheaper option.

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
