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?

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:

    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
    • There is a warning that "this thread is super old" but they ignore that anyway...
    • With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
