Hks Gt2540 Vs Hks Gt2530 On A Rb26

[toy515]

hey guys

ive got my hands on a pair of cheap 2540s and i was just wondering how the 2540s compares to the 2530s i know its bigger but how much laggier is it? how much more power will it make? also whats the difference between the 2540s and gtrs which one is bigger?

thanks

2540s are a terrible turbo. Nobody wants them. It's been covered in a few threads now.

They make pretty much the same peak power as 2530's, but with more lag and hence they always sell cheap.

Still bemuses me why HKS even released them when the 2835 was the better choice (as the time) if you wanted bigger than 2530's

They are not as big as GT-RS's.

Dont bother Ash, he will sell them and buy something totally different anyway..........and then ask about that aswel.

The search button isnt just a cosmetic addition to the forums

i can see why HKS did it but yeah the results weren't that great

you got a bit more power, but you paid for it with the penalty of more lag

as the others have covered off in other threads this where this is a bit of a power gap from bolt on replacement turbochargers

i guess HKS tried to fill that gap a bit but it came out with a more laggier penalty vs gains

un related

id like to an external gate GTR TWIN 2835 (1 of them) on a single rb25 setup and see how does that perform

yes i know wrong flange, wont mate up, but i reckon this could be a real killer

Actually the compressor wheels in the 2540's were larger than GTRS's use . 2540s used a 76mm T04E compressor wheel from memory in 46 trim where GTRS's have a 71.1mm GT wheel in 52 trim .

GT2835's also use 71.1mm GT comp wheels so again smaller than 2540's T04E wheels .

Don't know why HKS used that 2540/T04E comp , would have been better off using twin 2535's .

hey guys i have a pair of 2540's on my GTR which have been highflowed, does highflowing help with response in any way?

No, it makes it worse.
