Kkr480 Or Hks 2530

[l0WRB]

im running a kkr480 atm on my rb25det

ive got the option to bolt on a hks 2530 turbo

would this be worth doing?

kinda mixed up and not sure what to do

its genuine HKS item.

[silver gts-t]

i would do it just for the reliability..

depending how my km the 2530 has also

[r32sky_line]

Would be a bit more responsive.

[l0WRB]

turbo has had around 15,000-20,000kms on it on 14psi

[BLK33T]

I would assume it would be slightly me responsive being ball bearing as opposed to journal (kkr items are journal bearing type are they not?) ...

also aren't the kkr series only oil cooled whereas the HKS item is water and oil cooled??

if I could have my pick I would have anything HKS put on my car over anything else on the market

[LordNafe]

I would think you'd lose power going down to the smaller HKS item? 2530's are good RB20's, bit small for a 25 IMO

[InterCooL]

china turbo or japan turbo?

easy choice to me

2530 ftw

[LordNafe]

Don't get me wrong, I love the japan stuff, but he already has the bigger KKR. A 2530 won't make the same power. It's considerably smaller. If we're talking a comparable Jap turbo you'd be looking at something the size of a 2840 or a GT30 I would think?

[mesmerized]

how much power u making currently on the kkr?? dyno graph??

[l0WRB]

only making around 295rwhp

yes its laggy bout 4500rpm full boost

the car with 2530 on it i took it for a drive last nite, very good low down torque and mid range wheel spins coming on in 2nd but yeah

i dunno wot to do lol

help me!!! some ppl say 2530 2 small for rb25? im only really after 300rwhp would 2530 get me there easy enough?

[RBwhatever]

Wheel spin comes down to the condition/grip of the tyres at that power level. Crap tyres = easy wheelspin.

I hear the 2530 is good for 220rwkw on the RB25. Maybe i'm wrong.

[r32sky_line]

I'd go the 2530 if you only want 300hp at the wheels.

Nothing beats response on a street car.

[l0WRB]

well the motor has 250,000kms on it and ive been running 19psi thru it for last 6 months

so 300rwhp is pretty much the limits i think and response would be nice my thing is laggy as hell haha its a joke!

[FATGTS-R]

The 2530 should make same power as you have at present but not much if any more.

If your currently not seeing much untill 4500 then the 2530 will be much better and be overall a faster car.

obviously you're unhappy with your current lag and you've seen the down low response of the 2530. whats holding you back?

250000kms? wtf juz?

295RWHP@19psi, with fully boost at 4500rpm = VERY SHIT TURBO!!

For a turbo to make full boost at 4500rpm i would expect it to be pretty damn big and make at least 330rwkw (450rwhp)

Kkr's aren't shit ..

however the kkr430 would have been the better option... unless you want to use it for just drags etc. it's not going to get great response with a stock engine,

John Cane runs (drifter) runs a kkr430 on his Rb25det in his laurel and it goes awesome!

m8 stay with the kkr got a 480 on my rb35 i got 265 rwkw from it with full boost at 4000 there awesome

[silva33]

I had a HKS 2535 which is a little better but I have been in an RB25 with a 2530 on it and there is almost no lag! It was an awsome street car the only downfall it had was that you couldnt push it to redline you were better of shifting at 6 - 6,500 rpm...

I would do it.. it will make about 220 - 230 max but i have seen them run mid 12's in an R33.. PM Robo's on the forum, he had one.

Its not all about rwkw.... from how laggy you have said your turbo is, the 2530 would destroy the kkr setup on the street even if it was making a bit more power.
