I will try to upload the dyne sheet. Also has anyone else noticed the info missing from the bottoms of staos dyno results. Without all the extra info they look rather false.

Just a note I wouldnt be this pissed off it atleast made the same hp as the stock turbo. It fell a few hp short of the stock turbo. I know different conditions may be at fault but yeah for $100 more I could have had a better turbo without all the extra problems of installing a chinese/eBay turbo.

You made over 306.4hp (228.48kw) on the factory turbo? At what boost? That sounds awfully high (unheard of), especially from what I've seen in the dyno thread.

i just noticed i miss typed, sorry, it was suposed to read "it feels a few hp short of the stock turbo"

The turbotech boost-T are the best of the manual controllers. $30 off eBay, superior to your current turbosmart unit. Check the lines from the turbo for a small split.

The stock turbo will probably be more responsive since its small and very light.

Whilst your new turbo may get going only 300-500rpm higher in the revs, its right in the most-used range, so you're going to notice.

However, once it starts to sing, there should be no comparison with the stock turbo - it should pull pretty hard although looking at the dyno graph the boost does fade pretty rapidly.

While we're on the topic of boost controllers, I'll give another vote for the turbotech one off ebay, but as noted in earlier comments, probably not a good choice for high boost applications.

The turbotech works well around 10-12psi, maybe a little more, but anything over say 14psi really needs a decent controller.

Hope you get it sorted.

I really would like to get a blitz boost control as ive got a blitz fatt. But I thought blitz had been sold and they are a different brand now. But I saw one on eBay. So yer :/

We have wuite a few guys running 30-32psi on teh original controller but yeah teh new V2 isi far superior at high boost..In fact it holds 60psi rock steady under test and to be honest I havent even tried to find its max. it's all in teh desin of the seat and teh speciallly imported ball for the gate that seals solid. Normally gated controllors have a hard metal ball on a metal seat..teh V2 has a metal seat but teh special ball is not metal or ceramic. It is hard but has some flexion so it seals tight.

Cheers.

Why do there seem to be heaps of people who like the Blitz dual solenoid units?

I don't really understand why you'd need two solenoids, and why Blitz seem to be the only people peddling a dual solenoid EBC.

I think it's something like one of the solenoid valves adjusts in big increments and the other in small increments. So with the two working together you can get better resolution/control than units with just one solenoid.

Why do you think the Mac valves are good for automotive applications? Some of the plant that I maintain uses banks of Mac valves and they are still going strong after 10 years, but this is with filtered / dried / cooled air. So I think they are a reliable valve but performance wise I don't know, they still only do the same job as all the festo, smc, norgren valves we use.

PS my gizzmo unit uses a Mac valve and it does the job well.

I installed an IEBC on the weekend & ended up using the factory solenoid to do the control, just rerouted the hoses & wired it up to my controller.

I tested a solenoid I had bought 15 years ago, but it didn't want to pulse reliably above about 30% duty cycle so gave it the flick in favour of the one Nissan already supplied, thanks guys :thumbsup:.

A Mac valve would be better...

I ran a small MAC on my Haltech setup for about 6 years - worked fine. I'm just using an adjustable wastegate actuator rod on y DR now because it's only running around 9psi, but I might build another IEBC and see how responsive I can make the old TO3...

You can just see it (circled) in this old photo when it was fitted to my Z.

      "Cheap" bolt on turbo on RB25DET NEO

      The fab work can be as simple as a couple of silicon hoses and clamps to the factory piping.

      Just sounds like either way you need to do some fab work to get everything to fit, so why limit yourself at that point? If the GCG high flow option is zero effort in and out swap though I'd probably do that. It's almost certainly lowest risk, lowest cost, etc. The HKS GTIII-RS option that Kapr mentioned is laughably expensive for what it is, they charge the exact same for two turbos on the RB26 so their margins are off the charts on that thing.

      "Cheap" bolt on turbo on RB25DET NEO

      Intake manifold is not a part of the issue. The turbo bolts to the exhaust manifold. That is easy. But close your eyes and picture the physical situation. That is a T3 flange on the manifold and a T3 flange on the turbo. As long as any new turbo has a T3 flange on the exhaust housing, that exhaust housing will bolt to the exhaust manifold. This places the exhaust housing in the same place as the stock one. But now move your mental attention a little further forward. The location of the compressor housing is set by the length of the turbo's core. The stock turbo had a long core. Let's say that it is..... 100mm long. So that would place the compressor housing 100mm forward of the exhaust housing. But a highflow, might well have a centre core that is shorter. Let's say that it is only 70mm long. Now the compressor housing will be 30mm further back in the engine bay than the stock one. This DOES move the turbo's compressor outlet backwards. It also moves the compressor's inlet backwards. You will very likely have to do some work to both the inlet and outlet piping to make everything connect again. I am not say this to make it out to be a bigger deal than it is. I am just pointing out that "bolt on" is sometimes not quite bolt on. The highflow from GCG that Murray linked above (https://gcg.com.au/turbo-charger-upgrade-skyline-gtst-2iu-xtrgts-s1.html ) uses a core that is the same length as the stock core, and so does not require this extra work. It will look very much like the stock turbo. No-one uses GTR turbos of any flavour (stock, or aftermarket) in a single turbo application on RB20/25. It's not a thing. Yes, people have been putting on GT3076, GTX3076 (and bigger and smaller versions of those) and G30s (of various sizes) onto RB20/25 since forever. But these are not "bolt on". Everything except the 4 bolts to the exhaust manifold change with these. And genuine Garretts are expensive. Non-gen, like Pulsar, etc, are cheaper, variously as good or nearly as good. But still not bolt on. No-one in the right mind would pay for an HKS turbo. Not in this modern day and age. Well, yes, the GCG highflow. You could ask HG what he can do to make the compressor housing sit in the original location. There are surely others doing highflows around the world. And some of the eBay/Temu ones (as reported by Dose) work and don't die. Bit of a lottery though. I would send your turbo to GCG (here in Oz) to be highflowed if you want a trivial no-extra-work option. But seriously, the work required to change inlet and outlet piping is not that hard. That's a boost control problem, not a turbo problem.

      Thank you all for the replys 🙂 I know that intake would be different but that is one pipe at it is not that hard to get(custom one). I meant mainly bolt to the stock manifold and the turbo elbow. I looked and many sites/forums but they are just "old" with some old HKS turbos from GT-R i guess? What about some Garrets?  Or any other turbo? Is there even a turbo which i can just bolt on? 😄 And yeah i know about that new HKS but that is like 2000k USD without taxes/shipping in here   Iam getting a touch up tune but my "problem" is that on the "not" hot day iam getting peaks around 0,9 bar...and when it was around 15 Celsious i saw peak around 1 bar which is just too much for stock turbo. And of course turbo is old and i like to get some new one for a piece of mind 🙂

      I'm working on the assumption that our friend Jasmine here is a Russian (or, possibly Ukrainian) spammer/spambot, based purely on the number of such that I have been having to neuter in the last few weeks. IP address for the OP above was in WA. But that could have been via VPN. Posting at quarter to 4 in the morning is a good sign of being from somewhere in Europe. The last Jasmine that I kicked in the cooch was IP addressed in Ukraine. Even that could have been via VPN, and the bitchbot could have been from Russia, Serbia, China or anywhere. Regardless, was a spambot, so I killed it with fire. The fact that our new friend Jasmine here did not respond in any way to my tart query strongly suggests to me that this OP was just the establishment phase of a user able to be activated for spamming in a week, or 3 or 10.
