2530 here. Making around the 200rwkw mark @ 1 bar.

Mods in my sig.

My brother put a T04 on his 32 and is running a powerfc. Over 300rwhp. But when i drove it i noticed that 1st doesn't really boost at all and 2nd isn't much better. 3rd gear hang on lol.

I'm lookin to update my turbo .. but i'm in two minds ..actually 3 minds on which one to select..

Help me out.

(sorry for hijacking thread a little)

HKS 2530

or

Garrett GT28R

or

Garrett GT RS (GT28RS) i think

i'm lookin to run 1.2bar ..and produce around 240rwkw

Are these capable of this? with injectors, ecu, fuel pump, cooler and cams?

thanks

Matt

mm2death- how hard does your r32 pull, what is your redline and when does boost come on? thanks in advance.

Yeah goes great. I've made a few people shit themselves...lol. But like with everything, you get used to it and then after no time at all you wanna go faster :D

Redline is about 8...not totally sure as i always shift at 7 the most. Boost hits fully at around 3500.

Cheers,

Scott

Hmmm, this thread is interesting

I have always thought my turbo was a HKS GT2510. Due to the CHRA tag being un-helpful (no numbers that meant much) I have always taken the sellers (JMS) and the installers ( Tilbrooks ) word for it. Also has a HKS 1bar acuator (although it only gets it to 0.9bar :) ) and also has a cast HKS dump pipe

It bolts on, and is definatley a HKS 25 series from the housings etc, but looking a MM2deaths post, how you say full boost is at 3500rpm, I am now thinking differant

Mine makes 200rwkw at 0.9 bar, and full boost is from about 4500-4800rpm and pulls really well from there to the rev limit at 8200 rpm (re-mapped chip)

Any idea's? I am now thinking 2530 or 2535 perhaps?

from what i know the gt rs is an update of the 2540, similar and made  more responsive providing an extra 30 odd hp than the 2540 also.

i thought it was more closely related to the 2835 turbos. power between 2835 and 2835R, with slightly better response.

Hi guys, for what it’s worth, our RB20DET has a GCG ball bearing hi flow of the RB25DET standard turbo, makes 1 bar at 3,100 rpm, some boost at ~2,500 rpm (depending on load), has GTR cams, adj camshaft pulleys, std R33 GTR intercooler, split dump, no cat, 3.25” exhaust, Power FC with boost control kit, well tuned (not by me), 225rwkw at 6,900 rpm using 1.3 bar, power flattens over that but doesn’t drop off dramatically, revs to 8,250 rpm easily (needs shift light, badly).

The result is the sum of the parts, not just one single part. That means you won’t get a similar result (whether it is good or bad) just by choosing a turbo.

Hope that helps

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • 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.
