HKS GT 2510 on RB20 results???

[boosted_32]

has anyone ever put this turbo onto an RB20 and have any dyno results or any feedback how this would peform?

Thanks

We have had 2 X 2510 's on a GTR. It is quite a small turbo, so a single one would have not much airflow capacity over 200 rwkw I would think..

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?

I think it'd go close, how does it compair with the figures of an r33 turbo? Theyd be good for probably 280-290hp, if its bigger than that i dont see why not

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 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.

Yeah, makes me think mine is definatly at 2510 - just runs out of flow, no matter what boost its set too

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.

[Chris32]

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
