rb25det HyperGear vs Pulsar Turbo RB25DET

[Kinkstaah]

Probably still better to sell/return and get the EFR7670 in T3. 

... won't be twinscroll tho. So buy it in T4.

The hype over transient response is real for those turbos.

I'd rather have a fabricated manifold change and not have to change all your other stuff, versus using an adapter and have to fabricate your intake, dump pipe, and have a gasket, bolts that come loose.

Plus all the other shit involved with mounting a turbo which I cryraged about many times with many failed f**kin turbine to manifold gaskets and shit, why double up. Get a f**kin twinscroll Vband manifold

You could realistically also just change your manifold entirely. That may be cheaper or more expensive depending on what the quote is, versus buying a new manifold, selling current manifold cost, waiting for fabricator versus waiting for delivery on replacement item, then dealing with "It mounts in the same spot!" to find out that alas, it is slightly different requiring fabrication anyway

Or you could just YOLO it with a single scroll rear housing... but we're well into 'but what's most optimal...' now.

You’re one high-energy passionate enthusiast and I’m here for it! Haha. But too late! Went with the G30-660 with a custom built housing! I asked Tao from HyperGearTurbo if he could add the option on the website and he agreed! So if there ever is another poor soul in my situation they now have the option to buy it  

Total for supercore + housing: ~$3585AUD

and I was considering turbos from Pulsar/ HyperGear for  $1400-2500 AUD 

…Well! I’ll post up the dyno results when I get to that stage! Thank you all for your input!!

Sincerely,

A less hot, learning head

Haha a polite way of describing Greg...

If you've ever followed his many builds, you'll see he constantly gets Greged or Gregged up.

Him a few others on here are masters of BW EFR propaganda, don't mess with them because you'll get EFRed up

Dad jokes are strong as of late.

It will work great. Water under the bridge by the time it's up and running. The G Series platform is probably the most absolutely rock solid option you could have possibly chosen.

Some of us.....like me.... have travelled many paths and know from experience that some options, decisions, paths are better than others.... :p

Haha... The SAU old timers, we've been there, done that and still haven't learnt our lesson(s).

Sorry I don't agree, at least for the G30-770/900, The G30-660 isn't far off to a 700 response wise and doesn't make as much power.  Referring to my last few dyno runs from Rb30det. Power and response of the two G series tested were no where near to the current model ATR43SS-3. But I respect everyone’s preferences. Free data for everyone who’s interested to know the performance ceiling of those two G series turbochargers. 

All three turbos run to a point that no more power could be made / no more boost could be held. Everything else apart from the turbo stay unchanged.

Are those Garrett G series or copies?

Copies. Their results I'm not going to say idential but very close to geninue

UPDATE:

Hi all! 

As we are getting towards the end of this thread where I’ll showcase final dyno numbers and graph, I wanted to provide an update.

Tao from HyperGear has done an amazing job building the custom divided T3 housing for the G30. Communication was flawless, price was great, and now the housing is estimated to arrive in 7-10 days! Very very pleased.

I must add, if someone is looking for an affordable turbo and end up reading this thread, I would recommend HyperGear. Genuine brands are the way to go as their proven reliability, predictable performance, and there’s a plethora of information available for specs, flow, and more. This HyperGear recommendation is based on their excellent communication, dedication, and willingness to listen to their customers. I particularly liked their ability to create custom adaptations tailored to specific needs, which is a HUGE benefit over other brands. And if we consider the HyperGear provided dyno results, it adds reassurance knowing their turbos can compete against genuine brands.

Next update will be after the dyno!

The fact that Hypergear has been posting here for like 10+ years would 100% make me go to him for a turbo upgrade. Glad you got what you wanted from them.

Super keen on the dyno results, make sure to post up ECU logs with RPM vs. MAP vs. ignition timing (if you want to disclose that).
