rb25det HyperGear vs Pulsar Turbo RB25DET
Eric0 replied to Eric0's topic in Engines & Forced Induction
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! -
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

Update 3: shipping will be 100AUD. I do think a total of 1100AUD is doable for a custom built G30-660 T3 TS .82 A/R Vband, but I’m also finding T3 to T4 TS adapters for $67AUD and a .85 A/R TS T4 housing for 500AUD. I know the turbo would sit about 1.25cm higher (which means redoing my downpipe and intercooler piping) and two gaskets…
-
Update 2: To make a custom TS T3 .82 Vband housing to suit a G30 super core, it will be $1000AUD. I’m still inquiring shipping cost
-
Posting an update: Contacted HyperGear, Tao said he might be able to build a T3 .82 TS Vband! Waiting to hear back on cost and shipping.
-
I’ve reached out to HyperGear to see if they could build a compatible exhaust housing. We’ll see what they say! I currently have an external 44mm tial wastegate on my manifold.
-
Close, but it’s not a twinscroll housing looking for a divided T3
-
I’ll reach out to him and see what options we have on building a custom housing. I’ll report back
-
Well… maybe I do go back and look into the 7670? I’m seeing a .72 T3 twinscroll option. how does the spool compare to the g30-660 series?
-
I’m seeing T3 to T4 twin scroll adapters. This should work? https://privatelabelmfg.com/products/precision-works-t3-to-t4-divided-turbo-flange-adapter?variant=34085762138250&tw_source=google&tw_adid=&tw_campaign=18293857672&utm_term=&utm_campaign=**LP+Shop+-+pMax+-+Precision+Works&utm_source=adwords&utm_medium=ppc&hsa_acc=8464848152&hsa_cam=18293857672&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gad_source=1&gbraid=0AAAAADla3MIVCZh3G3-4mL4aDYDUhP9n8&gclid=EAIaIQobChMIo9q-2PyEiQMVmA6tBh3enzi_EAQYASABEgIgnfD_BwE Feels kinda silly stacking plates and adding another gasket.

Those are some serious numbers! Based on the input I’ve received, seems like the G-series would be the move for same power and response 🙌🏾 Thanks for sharing, and confirming that a G-series turbo is the move! I can post my before and after dyno results and see what changes going from a GTX to G-series has
-
That’s what I’m noticing… seems like a popular size is 0.82 A/R, I’m considering this: T3 twinscroll .82AR, but I’m unsure what brand because I’m not seeing Garett having the option.
-
Okay! I bought a Garrett G30-660 supercore! I’m thinking of parring the G30-660 with a T3 .82 twinscroll. What do you think? Any advantages in spooling if I stepped down to .62? Seems like it would restrict the engine to about 400hp
-
I’m starting to lean towards the Garrett G30-660 but wondering what exhaust housing I should select for the 450-550 power range with quick spool. Any thoughts on this?
-
This was amazing and something I feel like a lot of younger enthusiasts, like myself, need to hear. I've been observing a local dyno shop spitting out 650-800HP RBs but when looking at their graphs, the car is basically dead until 5-6k RPM when it skyrockets. I’ve decided to change my goal and go for that 450whp mark and aim for quick spool, responsiveness, and practicality (I can't afford my engine being a consumable, haha). Now, looking for the best suitable turbo for this application, I'm considering: • Garett GTX3076R Gen 2 ( .62 or .82) • Garrett GTX3576R Gen 2 ( .62 or .82), room for improvement later? • HyperGear ATR43SS2 ( .62 or .82) • Pulsar PSR3076 ( .62 or .82) • Pulsar PSR3576 ( .62 or .82), room for improvement later? Any recommendations? I know the HyperGear and Pulsar aren’t name brands but they’re sure budget friendly
