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.

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....

So true mate.

How much power does 28psi provide?
28 psi........holy damn lol 2lV8ETR what kinda power are u making?

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.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
