Hey all,

Im torn between a Hi-flow or a new HKS GT-RS.

Looking for some personal opinions here from people who have used either of these or have had a chance to compare them.

Looking though some threads ive noticed the GT-RS has a slightly better power curve on the dyno but was wondering does it justify the extra cost for what seems to be a relatively similar peak power to the GCG hi-flow. I'm chasing street response, no lag monster suggestions please! :P

Well all opinions are welcome!

Thanks,

Dragonforce

I"m running the GCG high Flow.

I've been really happy with it. It makes good power and with cams, I've got a pretty fat power curve.

Check out the Dyno graph comparison website in my sig, and have a look at the power curve between my car and some of the GTRS equipped cars.

If I could have my time again, I would probably have gone GTRS or probably even 2835ProS.

At the time of getting my turbo, I'd blown the old one and the fastest way back on the road was a high flow.

Someone here PM'd me just the other day saying they really like their HKS GT2835 Pro S 0.68 A/R on an RB25DET .

The full kit may look expensive but they give you everything to make the turbo fit like all lines a dump pipe etc .

The call was that its very similar to the std pea shooter turbo right down low but comes on reasonably quickly - like a road car turbo should .

This person thought through someone else experience that the 0.87 A/R exhaust housing option cost that nice low-medium range squirt and for the small amount of top end it wasn't worth it on an RB25 .

The guts of it is that the 2835 Pro uses a slightly larger trim version of the same compressor family as the GT-RS uses .

Turbine wise its a little larger and a different family to the GT-RS's one .

Exhaust housing wise the Pro S one is a MUCH better design and with the 2835's turbine will make more power for stuff all difference spool wise .

Like with any change to a turbo engines breathing abilities you HAVE to tune it properly to take full advantage of the upgrade . This kind of thing is a bit beyond what the std computer wants to deal with and dito for the std SMIC .

Sounds like a real nice can live with it everyday road car option to me .

Cheers A .

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
