Hks 25/30 Rb20

[NizmoNigga]

Hey,

Did multiple searches but none of the results really answered my questions.

Want to get a HKS 25/30 for my RB20 just got a few questions:

The HKS 2530 rated to be 320ps/315hp, so providing that the engine has supporting mods, how much boost can the standard internals rb20 take?

Can the 2530 be hiflowed to provide more power if i want more power in future? if so will i loose out on response the turbo makes with the rb20?

I had some more questions but cant remember it right now.

Thanks

I'm pushing 28psi through mine and I've had no issues for nearly 3 years now.

Awesome, cheers for answering that question.

r31nismoid can you answer my other questions with your infinity knowledge about rb20's lol.

Cheers

How much power does 28psi provide?

I'm curious as to how the 25/30 is different to the stock rb20 turbo in terms of size and also response, if anyone knows?

This is not answering your question Pat O, but after reading so many thread's on the 2530 on a RB20, some people reckon it makes a huge difference in response, torque and obviously power. Ofcourse this is going by other people's words.

Yeah, I've heard great things about the turbo too. I've been considering a 2530 for some time now, just have to decide if I want to spend the extra cash, or go for a cheaper alternative. I guess it always comes back to the "you get what you pay for" situation...

my rb20 has the 25/30, made 206rwkw, injectors and computer is holding me back, feels great to drive though i dont havent had much feel of other turbos besides stock ones. get full boost (bout 15.5) before 4grand then pulls very hard all the way, gotta rev the rb20 hard so next gear is in peak range and avoid boggy response. i reckon the rb20 loves being in the 5k to 7k range, the pull is very strong, breaks traction (235 17's rear with slight camber) in 1st easy, in winter nice cold days forget 1st, 2nd gear spins too !!!

not too sure on specs of the turbo but i do know the internal waste gate is bigger than stock.

thats just my car, i wud bee keen to see wat others say, hope it helps....

In the vicinity of 280rwkw. A lot of us are surprised that she's held out this long with 100% stock internals.

I have a spare engine sitting here waiting to go in when this one finally pops, but so far all is sweet.

I want to wind her up a little more but my injectors are slowing me down at present.

There have been a few SAUWA & WCC members who've had a ride, and they weren't disappointed.

I don't have a 2530. I use a custom built T3/T4 that was built from the ground up for me personally by Grant at Per4manz.
