HKS GT2510 - 300 PS Output

COMPRESSOR:

-Wheel- 63 Trim - 47.7 Inducer / 60.1 Major

-Housing- 60 Inlet / 50 Outlet - 0.60 A/R

TURBINE: -Wheel- 62 Trim - 53.0 Major / 41.7 Exducer

-Housing- GT25 inlet / Internal GT25 oulet - 0.64 A/R

Its a hell of alot bigger than a standard RB20 turbo though, do you think it would produce 300hp? with mods such as stainless manifold, stainless dump, 3" zorst front mount bigger injectors, fuel reg, bigger fuel pump running more boost?

Seems like that is what mine is, as it doesn't matter how much boost you wind up, it seems to run out of puff at around 200rwkw. The response if awesome though, very little lag

Mine made 200rwkw at 1.0bar, and has made 205rwkw at 1.3 bar - but at 1.3bar there is a extra 40rwkw at 100kph, so it gives it a big mid-range hit of power

Trying to work out if anything poses a restriction on my car at the moment, 210rwkw would be nice, even 220. Maybe with cams and cam gears it may get there

HKS GT2510 - 300 PS Output

HKS seem to rate their tubos about 10% conservative.

So 330 PS = 245 kw - 50 kw for transmission losses = 195 rwkw.

Looks like HKS and I agree.

Pretty irrelevant in this instance, a it simply runs out of airflow. So no matter how much you improve the efficiency, it has no more flow to give. Reducing the restrictions would (as always) result in lower boost levels, but they have no effect on the maximium airflow.

:P

Do you have a dyno-graph? I was looking at a 2530 eventually but i think i'd be happy with those numbers if a gain in response was there with a 2510.

yeah sure

this is before and after - before was stock injectors/chip

after PFC and injectors

I want to try some cam gears next to try and get more top end - at the moment its pointless revving it over 6500. I want to move the power up in the rev range

It would make a awesome drift turbo, lots of torque midrange

    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
