Hks 25/40 For Rb25

[Dean_HR31]

Hey guys,

Ive come across a decent deal on a HKS 2540 turbo for my R33.

My motor is currently being rebuilt with forgies, gtr rods, 720cc injectors, 040 pump etc.

I will be using the car for street & track drifting. Im after something with good response & decent power output.

If this turbo can make me atleast 240 at the rears ill consider it, dont think 220-230 will cut it this time around....

Let me know guys!

my friend sidewayssam has the 2540 on his r32 with rb25det it is very responcive, he is running his at 14psi but only making 265rwhp, he is gettin it retuned next week tho, they are a good turbo

[eddieeeee-ro]

i heard they make 250-260 at wheels on that motor? with like 18+psi

[sidewayssam]

are u talking kws or hp? i have a rb25det with work done too it, i have the hks gt2540r and running on 14psi it has 265.9hp on a crappy tune, i have heard by many people that the 2540 on the rb25 can produce up to 350rwhp, as pimpn said im gettin my car re-tuned next week by tenagah motorsport, i will bringing the boost up to 16-18psi depending on what power it has, ill let u know how it goes

search a bit... the 2540 has a bad rep for being laggy. but is pretty commonly regarded as being good for 250 rwkw's on a 25

[sidewayssam]

really ppl say there laggy? it depends on the tune though doesnt it? mine has f**k all lag compared to alot of my mates rb25dets

[Dean_HR31]

really???? I thought the HKS 2540 would be a GOD with response! Especially if it only barely makes 240-250rwkws by what ive heard!

Can someone confirm this?? And please talk KW's not HP...

[sidewayssam]

yeh man my mates car are fairly laggy but i have the 2540 and it may not punch out the big numbers but the response is awsome

shit turbo

2540 is a mis-match from HKS, not their best turbo.

2530 is a better choice, virtually the same outright power, with a much better midrange/response.

There have been a number of threads on them now.

It served its purpose at the time, better turbos out there by far these days
