Im in the same situation..

Im probably going to just get my standard turbo hiflowed, its cheaper and easy to take off/install yourself

If i were to buy a new turbo, i wouldnt bother 25xx ide probably go all the way and get a 2835, 550cc injectors etc and bask in the 260-300rwkw :uh-huh:

Do a search for the GCG Hiflow threads. Sydneykid has spend many hours replying in these particular threads as he has a GCG Hiflow setup on an R34 GTT pushing around 250-260rwkw (with a full listing of mods too).

My opinion is that replacing a turbo on an R33 GTS-t that only netts you 210-220rwkw is a complete waste of time and money. If you were to upgrade all the support systems (exhaust, fmic, fuel pump, ex cam gear, ebc, ecu, etc) then you would already be pushing very close to 190-200rwkw so how is 200rwkw -> 210-220rwkw worth $2k for an aftermarket turbo?

Different people want/expect different things. To me a turbo upgrade is a 40-60rwkw not 10-20rwkw.

why dont you get the GT-RS turbo, HKS have now released it in T3 flange to suite RB20/25 as a bolt on application.

its rateed at 400ps the same rating as a 2835 but responds more like a 2535.

best of both worlds there, it would be super responsive on an RB25 yet flow some serious top end...

you should make at lease 250rwkw with a 2530, i would imagine some good figures would be seen with the GT-RS

LOL...bbenny is keen to see some GT-Rs results :D

The GT-RS is a good idea, could be the next good thing as far as bolt on low mount turbos go. But havent seen many results to date, just read a few articels that see them making 220-230 rwks on SR20s and 300rwkws in twin form on a GTR so havent really made up my mind that they offer 2540 power yet.

I dont think you will ever see 250rwkws out of a 2530 on an RB25 as the boost always seems to fall off at high rpm...may explain the 2530 kit i saw with an external gate?!?!?!?!

Remember this is a std engine.. You are limited by the amount of boost you can run.

I wouldn't bother with the std item high flowed for the price you pay for a s/h GT2530.

The response is much better with the 2530.

It really depends if 220-230rwkw is all you are after in the long term.

OR.. You could spend 3k on a turbo like Freebaggin's

Its made ~280rwkw to date with a std engine and reasonable boost.

Thats cos everyone wants more powah :D

The HKS range especially the GT-RS range is really expensive, you wont get it on your engine brand new for less than $3K

or twice the price of a highflow from GCG/ATS

the difference in response between a GT-RS/2530/2540 and the standard turbo highflowed is very minimal, and definately not worth an extra $1500

      Need AC Compressor for R32

      By silviaz · Posted

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By silviaz · Posted

      Ah, to clarify if the car has already been tuned and has been modified and you want to go from a oem cat to a 100 cell or decat or vice versa.Are you saying that the car doesn't need to be tuned after a cat change if it's already been tuned?

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.

      Does 98ron contain ethanol?

      By Kinkstaah · Posted

      That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter? I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

      Need AC Compressor for R32

      By GTSBoy · Posted

      Auto electricians that do repairs on automotive AC systems can source service kits. I don't know where they actually source them. I do know that there is one available for the R34 comp that I would need it for. If you have to pay someone to dismantle, clean and do needed repairs and fit kit contents, then you'd probably end up spending a good fraction of the cost of a new one. I would not be paying for that, because I would be doing it myself. My mechanic (bro-in-law) will happily source what is needed. Back in the day (like in the 80s and 90s), rebuilding an AC compressor was the standard approach, same as for starter motors, alternators, etc, because new replacements were v. expensive. After the China manufacturing boom and the rise of the disposable approach to everything, people just started throwing broken/worn stuff away and not rebuilding things.
