Peak Power at 5,500rpm! Noses over rather badly after 7,000rpm. He has HKS cams and what looks to be a 10cm exhaust. I wonder if its the std inlet that makes it fall over or simply the little 25G wheel running out of puff.

Would be a bit of an animal to drive with that graph. Makes me think Kando needs a T78 for all the RBDirty folk :)

I stick to my statement. Your always hanging around waiting and encouraging somebody else to try before YOU buy, I straight out don't appreciate that. There's a difference in attitude between quietly keeping an eye on someones build and purposefully encouraging them to hurry so you can see how it turns out for you own benefit. You have some audacity to talk about other members of this forum.

You can call me childish or whatever else you want, fact is I am an asshole and always tell it how it is. I'm not afraid to hear one more goof call me an asshole or a child or whatever else you would like to say, go nuts.

Fact is you and I watch the same threads, Ive probably inadvertently read 90% of your total posts, and I can safely say you have a crappy attitude towards this forum and the help you get from its members. End of story.

Do you really think I care what YOU think or appreciate??? RE: 'and purposefully encouraging them to hurry so you can see how it turns out for you own benefit.'..where are you getting THIS from?? Where did I say, 'hurry up, I wana see..' yada yada.. Even if I did, what is wrong with that/ Who are YOU to tell me what I should do?? Especially coming across as some stupid 'hero kid' with ginger just-grown pubes who thinks he can tell people what to do, you have been in here far far longer than myself, know more Skyline stuff than me, YET have very low levels of maturity and attitude. Grow the fk up you moron! I will ignore your posts now.

And of course I appreciate all the help I get on this forum, have said and thanked members countless times and helped others myself.

Either that or could it be that with those bigger cams the exhaust side is choking?

I think the 25G wheel is just maxed out. If he had a bung in the housing seeing what the back pressure was you would get a feel for how the L2 turbine and 10cm housing are doing keeping up with the cfm from the 3L.

Wow, depressing to see how easy that thing makes power :(

Interesting though that the low boost run that makes 300rwkw also has the same drop off, does that mean that its not the turbo running out of puff but something else?

The compressor follows its "pump curve" based on the pressure ratio. So whilst you are limiting your shaft speed the the compressors ability to keep up with the breathing of the engine is going to be roughly matched at low boost as it will be at high boost. That's from 10 sec think about pump theory. Others should jump in if that's wrong

Re bigger RBs...yeh yeh. I enjoy playing with the little 20. The way I see it the lil 20 is like a fine tuning fork. If it works in the 20 it will work on the other RBs, however you may not notice the difference on the bigger RBs as they have airflow to burn and not as sensitive to changes :)

I doubt the 25g is out of flow, I did go an extra 30kw more than that. I would be pointing toward the cam timing being a bit shonky like most RB30's... There is no way that should dive like that after 5000rpm and when I have seen them do it in the past it's because the cam timing isn't set correctly

EDIT: I didn't realise it was a shitty R32 RB25 head, so that is probably more the reason :whistling:

holy crap cake, that 30 would be devestatingly quick for a traffic light warrior with soo much torque at those sort of rev's. I'm deffinitly sold that if I'm replacing my turbo it has to be a TD06H-25G or bigger. KD do make TD07 and TD08 turbo's so no reason they can't make a T78. probly just have to ask to have them to list 1 on ebay or the shop front. they Listed other things after I asked them questions on selling parts.

But like you said it sucks at making power easily.... why do you persist??

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
