without listing the full car specs

its impossible to tell

it might be cheaper for a 2530.

depends on every mod that you have not listed

hey r31nismoid, say with the basic mods:

- boost controller

- 3" dump/front

- 3" hi flow cat

- 3" catback

- fmic

- safc

- fuel pump

what would you prefer from either turbos that would produce more power, hi flow or 2530?

what would pull better 1/4 mile times?

the 2530 will peak and drop off more im pretty sure. the rb25 turbo upgrade thread has plently of hiflow and 2530 graphs to look at and compare against. the 2530 is probably cheaper but the hiflow will perform better i expect

just for some information

i just bought a hiflow for 800

it did have a bit of play in it, and it is plain bearing turbo.

it cost me around 200 bucks for the rebalance, and 270 thrust bearing.

not sure what size wheels are in the turbo, but on my stock turbo i ran 12 psi and had 201rwkw.

with the hiflow i notice a significant difference in power, and spool time.

and when it winds up now, it sounds like a truck.

i ran a 14.089 with the stock turbo, but it was only my 4th time out there

and i didnt get my starts as good as i would like

i'm hoping to rund some low 13's next time i get out there and put the boost up to 15psi.

GCG don't do two stages anymore I don't think. The stage two had compressor surge issues.

SAU NSW members get 10% discount at GCG.

I reckon for an R33 GTST then a 2530 would get down the quarter quicker. Just so much mid range punch.

Aquariz you should get a powerFC with your turbo upgrade if you want to take full advantage of it.

i thought the hi flow turbo is meant to be stronger?

i know 2530 kicks in quicker then hi flow because hi flow kicks in the same as stock

doesnt it also have a big mid range punch similar to the 2530?

does anyone have a dynograph of the rb25 stock turbo and a hi flow... would like to compare

yea abo bob i wish i could get a powerfc on my car... just hate the fact that i cant... auto transmission

i was wondering which from the 2 and a gtrs will have higher rwkw by 5000revs? anyone?

Terry... Abo Bob already answered that

The "stage 2" is no longer in production, and shouldnt be purchased 2nd hand

cheers

Look, it's not the worst turbo in the world and they didn't have surge issues with all of them, just a fair few. It might be ok but it might be the reason the current owner is selling it.

I get full boost of 0.9 bar at 3200rpm but I do notice that it spools very early, just takes a bit to get full boost.

I think 2530 to run 12's is a proven combo. For some reason I don't seem to notice decent times with highflow turbos. I'm running 13.4 atm and I wont bore you with my issues but the weird thing is that I run very good times on the roudy roundy tracks. Maybe I'm just no good at the short one.

But still there it is, I've got 255rwkw with a highflow but I can't get a 12 but it has been proven that 220-240 from a 2530 will get you one.

Watch this space though. I might get there yet with a little practice. Going to a test and tune day soon.

The 2530 Probably provides more average power and at lower revs hence the better times. Got a dyno sheet by any chance?

My Hks 2535's failing after 75k kms due shaft play setting in and making wailing noise. Have ordered the

gt-rs and hope its a better choice than 2530kai. The gtrs is stronger from 3000rpm and has just slightly less response <3000rpm. From Hks web:

      MLR's Bogan cruise ship

      So, after talking to Tyson at Auto Tech Engineering about my "cunning plan", he suggested to "not piss money away on stuff that the car probably doesn't need" (the max IAT at the end of the 1/4 ever only seen around 30°C, which is in no way a issue, and as such, for what I use the car for I really don't need colder IAT anyway The whole point of the "upgrades" that I thought about doing was that my IAT started creeping up from 25°C to 30°C when cruising, then drop back down, then raise back up, rinsing and repeating, it has never done that before, so after talking to FI interchillers they assumed that it was the Bosch pump starting to fail, and if I was going to replace the pump....... I would do my usual thing of "while where in there" But, Tyson said he has seen similar things happen to IAT with failing or leaking AC compressors on other cars with interchillers, and as the AC compressor is 22 years old it is probably well on the way out anyway, and if a electric water pump fails it stays failed and doesn't just speed up and slow dow, but if a AC compressor starts to fail or is leaking, it will fluctuate and give a typical result to the IAT He said he could test the compressor and see how it is functioning and pressure test the whole system, but, as I do, I've just got them to order a new compressor to install to start with, and do a AC service and see if that fixes the issue That way, if it is the compressor, I wouldn't be spending lots of coin on something that wasn't the issue, and not actually needed, as the stage 2 kit, and pump, comes in at around $2k in parts alone, not including the plumbing and other parts that will be required or labour  And apparently the Bosch pump I have is really reliable and well up to task for the flow/pressure requirements that I need to keep my intercooler and massive amounts of boost heat (7 psi LOL) under control giving a nice and cold IAT A big shout out to Tyson for this, not many people will talk a idiot out of wasting money on car modifications, and the saved car budget funding can be wasted elsewhere on things that I may, or may not, need, like a nice new leather SS interior with red stitching......maybe I can convince the Minister for War and Finances into a nice trip down to Victoria for a week away to see the sights (I'll explain that I will need a hire car once we're down there so we don't have to worry about the Commodore being parked up on the streets at night, and it just so happens there's a joint that I can store it during that time) $1680 for all of the interior trims, + installation cost (I'll ask for a quote to install the trim if the new compressor fixes the issue)   https://leatherseats.com.au/products/leather-seats-trim-skins-kit-to-fit-vt-vx-vy-ser1-ss-green-black-diy-install

      Google tells me that's a Japanese Rat Snake... 2m long? Man I think Australia has traumatised me to think all snakes are dangerous unless they're pythons. Also... "16 years later..." is that a record on SAU @PranK?

      Yep, I really miss mine. I dont, however, miss it's understeer. Hard to find a genuine 'Sport' model these days. That sounds awesome! Good fun and great result!  I'd love to do a 1/4 in mine now that its reasonably healthy with the tune. I last did a run in my white GTR, I think it was a 12.3 and I can't remember the mph and I think the little E90 might be quicker.

      FWIW, I made 372kW on a Mainline dyno, with a stock motor (bar head studs & usual bolt ons) on E85 (pretty timid timing in the mid range) and it blew up after a year of track use. Probably got like 5~6 Wakefield track days and 1x skid pan somewhere in between.
