When i got my pfc and plugged it into my GTS25t it pinged its tits of.
After tuning it was fine.
If you want to see how good it runs with the base maps (with regard to pinging) set the hand controller to monitor detonation. It will log the current and the peak amount of detonation. I have been told that you can drive around with it pinging 20 all day. If you get over 60 that is the point your engine light will start flashing (if you have that option set in the pfc using the hc) and that is also the point at which i am told the pinging is audible.

With regard to the GT3040 comment as i said is was told it was close to a GT3040 in one conversation and in a later conversation they said it was close to a GT3530???
BHDave how long ago was it that you got your stage 2?? Have you got a turbo from a RB25DET and bolted it to your RB20DET?? When i talked to GCG they said that the reason they didnt push the stage two is the reason yours is so laggy (i am guessing). They said as per SeriesIIGTST's post on page one that all those mods where necessary to get enough air flowing to booth spool the turbo and not restrict the flow of the air it is compressing otherwise it would be laggy.

Call em and ask

From the latest wheels magazine "Flight Of The Falcon" they took it around europe and got some of the other car mags to review.
The first mag measured
Total Weight = 1774kg
Weight Over Front = 988kg
Second mag measured
Total Weight = 1774kg
Weight Over Front = 990kg

yeah they hi flow your excisting turbo but they told me they might be able to do an exchange but they didnt have any in stock at the moment.
I have been told the price is $1850 one time and $1950 the last time i asked them.
-
just remember the XR8 has apparently got an additional 150kg of cast iron V8 hanging over the front.
Also i thought that weight comparison means you have 52% over the front and 48% over the rear which is near an optimal 50/50 weight distribution??????
-
I got the same info when i called them today but in previous conversations with them they never mentioned the stage 2 because the new one combined stage one and two.
But as previously stated i would really like to hear from someone with this new stage one/two combo to find out just how it compares to a stock turbo and any other relevant points.

GCG are located in Sydney i think and their phone number is 02 97082122 (www.gcg.com.au). Call them up and ask them the questions above as it will be the most accurate answer you will get. If you get one let me know what it is like.

SLY33 I posted this with a good attitude but SeriesIIGTST kicked of with post full of attitude and it has all gone down hill from there. I was told that they had one turbo made up from the stage one and stage two turbo which is why i asked for people with new turbos "new". I can accept your criticism but as you pointed out i only asked for people with the "new" hi flow and all i get is attitude from SeriesIIGTST about using a search which by his own demonstration returned nothing relevant.
SeriesIIGTST PLEEEEEEAAAAAASSSSSEEEEE go and annoy someone else i really only want to hear from people who have one of these new hi flow turbos as i am seriously considering one since i am running 15psi through my standard turbo (borrowed time).
I'LL SAY THIS AGAIN
ANY ONE WANTING DISCUSS SEARCH ROUTINES, THE GCG WEBSITE AND ANYTHING NOT RELEVANT TO THIS NEW TURBO PLEASE CLICK THE "BACK" BUTTON ON YOUR BROWSER AS I DONT WANT TO HEAR ABOUT (note SLY33 i am not having a go at you in saying this i just want to get back to what this post is supposed to be about).
-
SeriesIIGTST this is getting tiring, call GCG on 02 97082122 they will tell you they only sell one turbo (for the GTS25t). It is a mix of the stage one and stage two because as i said they used to get surging problems. As such i would like to hear from people with the new turbo, apparently they used the compressor wheel of the stage one turbo and turbine wheel of the stage two!
Thanks Lepperfish. How long ago was it you got yours high flowed?
-
I work there (even saturdays) but i only drive on friday and saturday.
Drop by next saturday if you see my car out the front. Call the main phone number of the company i work for (please dont mention it on the forum).
The link below was setup a month after i got my skyline so ignore the blurb as it is 4 years old.

Checked those two threads you posted and they both refer to stage 1 and 2 hi flows. The new hi flow they do is one size only ie any threads making reference to stage 1 and 2 are USELESS.
I dont know how recent this change is but anyone that has one of these NEW hi flows will know what i am talking about and they are the ones i want to hear from.

A couple of weekends ago someone in a purple skyline pulled up in front of my work and according to the cleaners that where downstairs at the time seemed upset that he couldnt get in. PM me if you need to talk. Note i own the Red R33 GTS25t with an M Spec kit and Black 3 (6 depending how you define a spoke) spoke rims with a red edge.
-
There you go.
I just did a quick search and found Steves thread. Interesting reading
Personally i had a LSD done by Hills and i can fault it. Granted it took a couple of more months than promised but i didnt pay until it arrived so there was no problem there.
-
Subtle.
BUT i am after someone who has had one done RECENTLY because apparently the OLDER hi flowed turbos (stage 1 and stage 2) had problems with surging. THEREFORE i didnt bother doing a search because i am NOT interested in old posts only people who have had it done recently.
Maybe you (SeriesIIGTST) should stop posting useless help and tell me of your friends experiences if they have had one done RECENTLY. I hope i emphasized
RECENTLY
enough for you.
-
before you buy it why dont you talk to mark from hills motorsport in sydney. He does a modified gts25t plenum which feeds from the front and is heaps cheaper.
-
Has anyone had the standard turbo on their R33 GTS25t hi flowed by GCG.
If so how was the experience?
I am told that the new hiflowed turbo they do for around $1800 is equivelant to a GT3040 but as i am reasonably turbo ignorant i would like to hear from others who have used one of these. ie is it heaps more laggy, does it increase that wonderful turbo whistle we all live for, what pressure is it most efficient at, etc.

Its interesting how open minded skyline owners are.
I used to frequent the ford performance forums under the nick "Skyline" and i used to get harassed and abused because i was giving them grief over fords lineup of cars compared to skylines.
Oh yeah BTW full agreement with the Cult Car thing. Finally a boss at ford (Polites) who had the guts to stand up and say "fck it i want a car that is going to make HSV look stupid, hmmmm, lets turbo our new twin cam 6 for a laugh".
BUT what i cant wait to see are the two new FPV cars the typhoon and the hurricane. The typhoon being the XR6turbo running 9psi of boost, 550nm and 260kw. That is more torque than any australian production car including the V8's (correct me if i am wrong)!!!!!!!!! Hurricane will be the new Territory with an XR6turbo motor.
Check out page 7 of the following pdf.

PaulR33,
If you are going to use that device from oceancontrols you would still need some additional analog electronics to scale the voltage down from 5 to 4volts (depending on the output of your map sensor). The other thing to check about the oceancontrols device is the input impedance, if it isnt in the Meg Ohms you may have problems with them loading the outputs of the sensors on your car.
If i where doing this i would simply build a small 5V buck converter (LM2673 from nat semi or similar). Include an ADUC812 (from analog devices) microcontroller, it has multiple analog inputs (12bit i think, ADUC824 is 24bit) and serial ISP coms. Then on the inputs to the ADuC812 i would be using something like an LMC6464AIM (rail to rail single rail opamp) in a voltage follower configuration to give me a high input impedance. Depending on the frequency at which you log the parameters you may want to use external SPI interfaced FRAM or external parallel interfaced SRAM. I would get hold of a demo copy of the Keil compiler (limited to 4k).
The above is a massively over simplified explanation of the basic components that could be used, it doesnt address noise, filtering, decoupling, etc . It doesnt even go into the PCB (printed circuit board) you would need to design and build as micro alone is a 44pin PQFP which cant be wired onto a piece of veroboard. Also without programming and microcontroller experience you dont have much of a chance.
For the people that said you simply take a 20x2 character LCD (with hitachi driver chip) and download a program you must be on drugs. It isnt at all that easy because you get different LCDs with variants on polled or delayed parallel (4 bit and 8bit data bus) coms which all require variants on the main program.
Unless you have a mate that is an Electronic Engineer with micro controller experience i would be giving up. If you had a friend who was in their last year of uni doing their major project you may want to suggest they do a device that logs all the above information and electronically controls boost or something similar (i was working on this type of device using fuzzy logic to control the boost until work and girlfriend got in the way).
Interfacing to the point where the "Nissan Consult" connects (which you can see in action at you nissan dealer) would be a neat project but without an outline of the data being transmitted / protocol being used it would be like looking for a needle in a haystack.
I dont mean to sound rude in the above ramblings but i see it so often where people who DONT know, trivialise the hardest form of engineering (that'll get the mechanical engineers that frequent this forum fired up).
B2Barker stepping down a voltage with a resistive divider is simple and not done because your divider has to be able to supply a certain amount of current to the analog input. To get a high enough output current you have to use a resistive divider with low input impedance which will load down the output of you sensors and give your ecu incorrect values!!!!!!!!!!!! Again over trivialising a problem by someone that doesnt know what they are talking about.
The nissan conzult looks good though, the PDA is a neat and cheap way of getting an other wise expensive ($1K alone) touch screen LCD with colour interface.

How could you hear which chamber the ticking was coming from or was it with the ignition on only??????

Go to your local motor bike shop they will be able to extend the length of your throttle cable easily. From memory it cost me $30.................

Hills Motorsports down in NSW have a very nice custom plenum with properly tuned individual runners. They go for around $800. They rework the bottom half of the standard GTSt (R33) plenum and build a new top half. I am told that it performs brilliantly.
I had a friend who went from stock plenum to Greddy plenum and i remember he was disappointed because there was no major gain. I think he was running 20psi boost.

When i got my power FC and plugged it in it was pinging its tits off. Ended up having to take heaps of timing out of the base map and add fuel. I dont know about the rest of the people here but i wish the Autronic with the adaptor loom had been avail when i went ECU hunting.
With regard to the car not running with the EBC switched on (with no EBC connected) i just had the check engin light come up and it drove fine. I have heard of it stopping but i didnt experience it.
The hand controller is a pain because it takes heaps of time to take a couple of degrees out of the entire map (i know i can just turn the crank angle sensor) AND the map chaser function doesnt show you on the actual map only on a grid which represents the entire map which is REALLY annoying.
Oh and i am interested to know what other people have done about mounting it since mine DIDNT come with any brackets to mount it.
Outside of that it was a true plug and play unit.

You would have to assume that people are aware that if the BOV is changed so it vents to atmo there will be problems. This is because when all that air the MAF has just measured which it thinks is being vented into the intake (after the MAF) but isnt will mean there is less air in the system. As a result it dumps enough fuel into the engine for the vented air and the air coming through the MAF ie there is less air than the computer thinks and it gets too much fuel (floods the engine stalling it).
In short dont go the aftermarket BOV unless you can plumb it back. I am making an adaptor for my SSQV to plumb back so i dont look like a twat and have my car stall at the lights.
wats std power fc settings like

Back when i first got the pfc installed it i had a full 3 inch exhaust and bleed valve running 10psi.
Now i have that plus cut and shut plenum, ARC front mount intercooler, stainless piping, Pod filter, Bosch fuel pump and am running 15psi with standard turbo.
The next thing planned is rising rate regulator, better plenum and a GCG stage 1 high flow (i can keep dreamin)
