f*k this really

Relax bro.

First important point is that 500rwhp has been done many times on 2530's, so lets suppose there is a non-turbo related problem with your setup. If you change to a high mount now, you will not address whatever that problem is. Sensible steps would be; try another tuner (since your tuner has stated that the 2530's wont do 500), drop the exhaust (don't assume - verify).

Re: fuel flow, just keep an eye on injector duty, if its gets too high that means you have a fuel flow issue, as they are large enough for the 2530s.

i tried to read the gtx thread and omfg all it is in 50 f**kin pages is people spewing rubbish.

I found 1 guy who had posted up sheets of his old and new turbo.

This site used to be very helpfull but now all you get is people who tell you what not to do with short answers that help no one.Every one seems to know best but no one posts up any proof.

I come here to find out the best set up for my car to make the sorta power im looking for with some response.

I dont want to rebuild the 25/30 and try again to fail again on pump fuel,I want to change to a single but i get mixed msg from every one.Skylines australia used to be such a good comunity with people who were only too happy to help but now you get alot of people who mouth off and are stuck up assholes.

f*k this really

Trial and error with some setups. Research on more than one site. Find what u like and give it a go.

Not everyone is the same. Different people have different opinions, especially when it comes to what is considered laggy.

In regards to the gtx series, i would take status's advice. He has tuned alot of cars with different setups and would know whether or not these are any good. He stated they are not any more responsive and require big boost to come to life.

dont get me wrong i love the 2530s guys i love them.

I just want more out of them on pump

they start to spool at 3000 rpm and out of the gate they are just an awsome setup.

i think il give the gtx a miss too many people complain about them not doing what they are ment too.Id love to find some one who has a gtx 35r with dyno sheets on pump but no one seems to have done enuff testing.

As for my turner he is very good.

He seems to think my acuators are not strong enuff and they are closing on full boost.

Maybe thats all it is.

I know they fall over around 6700 and onwards.

Still yet to put the cams in as they are comming from japan.

They are odd tho

264 10.01 and i think they are 260 10.08 or 264 10.08 lift

stage 2 hks

Whos the best to see about rebuilding my hks 25/30s

my exaust should be good enuff its

mines sport div dumps

vielside front pipe into a 5 inch body balistic cat

twin 3.5 inch exaust

Id love to stay with the twins to be honest but i would really hate to have them rebuilt and have a massive fail on hp topping out around the 450-470 on a dynapac hub dyno.;............

Lets put it this way, those GT2530s will not be the cause you are topping out at that power - they go way past that power level on Dynapacks with no issue at all. There could be a very good chance that instead of rebuilding them, you put on a completely different turbo setup and get very similar results due to the fact it won't be the turbos causing it... unless you turn out to not actually have GT2530s of course.

Pull your head in and stop being so rude.

You're getting free advice for your problem. Be grateful.

What caused you to get those cams and is your head totally stock and not machined in any way?

To me, you seem a bit closed minded, and not really willing to give the ideas in this thread full consideration. IMO you should re-assess the beliefs you hold now. Let's just say "he may be very good".

He seems to think my acuators are not strong enuff and they are closing on full boost.

Maybe thats all it is.

You mean opening on full boost :) But then, why are you talking about a turbo upgrade if you have an actuator problem? At the moment you have a boost control issue, that is probably due to weak actuators, but you have yet to verify that.

my exaust should be good enuff its

mines sport div dumps

vielside front pipe into a 5 inch body balistic cat

twin 3.5 inch exaust

It certainly sounds good. But for sake of a little work why not verify that?

You need to slow down and troubleshoot this in a methodical manner. And to do that, you'll need to relax first :)

Good luck

well without making it to complicated,

here is a very well proven setup that will get you the results.

260 poncams, in cam +3 to 4 degrees advanced, ex cam -4 to 6degrees retarged. valve springs,port matched ex manifolds and 2530's on 24-26psi will have it in the bag. (ecu injectors fuel pump stock dumps and a good exhaust)

      Another BK R32 GTR money pit...

      By BK · Posted

      Have I not posted since 2022 ? wow... Yes, it's pretty much finished mechanically. I'll probably sell it soon as the old man is 80 in November, so 99% he won't ever drive it again. I don't really need 3 GT-R's and I haven't driven any of them since September last year - correction, drove my 33 earlier this year on Australia day. All of them have been like this since then.

      So, after talking to Tyson at Auto Tech Engineering about my "cunning plan", he suggested to "not piss money away on stuff that the car probably doesn't need" (the max IAT at the end of the 1/4 ever only seen around 30°C, which is in no way a issue, and as such, for what I use the car for I really don't need colder IAT anyway The whole point of the "upgrades" that I thought about doing was that my IAT started creeping up from 25°C to 30°C when cruising, then drop back down, then raise back up, rinsing and repeating, it has never done that before, so after talking to FI interchillers they assumed that it was the Bosch pump starting to fail, and if I was going to replace the pump....... I would do my usual thing of "while where in there" But, Tyson said he has seen similar things happen to IAT with failing or leaking AC compressors on other cars with interchillers, and as the AC compressor is 22 years old it is probably well on the way out anyway, and if a electric water pump fails it stays failed and doesn't just speed up and slow dow, but if a AC compressor starts to fail or is leaking, it will fluctuate and give a typical result to the IAT He said he could test the compressor and see how it is functioning and pressure test the whole system, but, as I do, I've just got them to order a new compressor to install to start with, and do a AC service and see if that fixes the issue That way, if it is the compressor, I wouldn't be spending lots of coin on something that wasn't the issue, and not actually needed, as the stage 2 kit, and pump, comes in at around $2k in parts alone, not including the plumbing and other parts that will be required or labour  And apparently the Bosch pump I have is really reliable and well up to task for the flow/pressure requirements that I need to keep my intercooler and massive amounts of boost heat (7 psi LOL) under control giving a nice and cold IAT A big shout out to Tyson for this, not many people will talk a idiot out of wasting money on car modifications, and the saved car budget funding can be wasted elsewhere on things that I may, or may not, need, like a nice new leather SS interior with red stitching......maybe I can convince the Minister for War and Finances into a nice trip down to Victoria for a week away to see the sights (I'll explain that I will need a hire car once we're down there so we don't have to worry about the Commodore being parked up on the streets at night, and it just so happens there's a joint that I can store it during that time) $1680 for all of the interior trims, + installation cost (I'll ask for a quote to install the trim if the new compressor fixes the issue)   https://leatherseats.com.au/products/leather-seats-trim-skins-kit-to-fit-vt-vx-vy-ser1-ss-green-black-diy-install

      Google tells me that's a Japanese Rat Snake... 2m long? Man I think Australia has traumatised me to think all snakes are dangerous unless they're pythons. Also... "16 years later..." is that a record on SAU @PranK?
