"Hybrid" is a meaningless term. I could not tell you what the vendor of that turbo means by "hybrid".

Hybrid sounds like a supercharger... It's half a turbo, with a belt to drive it!

Oh wait, they're just called super chargers...

Oh sry i do not know if i used the term right. What i meant is upgrade the internals and keep the housing.

That is not "hybrid"? 

That's why I said it is a meaningless term. Because there is more than one meaning that people can apply to it.

When we said "highflow", that is exactly what we mean, and exactly what is done. In a highflow, they take your housing and machine them out to take bigger wheels, have a better internal profile, etc etc, and fit a new core with the different/better/bigger wheels.

Ok thank you...maybe the term "hybrid" is used here to describe what you said :) 

 

And any other turbo that is "bolt on"?
Iam kinda leaning towards this new HKS:

It is bit expensive but it should be enough for my power now and in the future 🙂

What happened to looking for a cheaper bolt on turbo? 

I don't think you'll find anyone here (that isn't American) that will recommend this turbo... its absolutely crazy money for what you get.

I think it's terrible value, it should be half that price IMO. And I'm known as someone who will unironically suggest the GTIII-SS on the RB26 if you have very specific requirements. The GCG RB25DET "hybrid turbo" is 1/3rd the cost of this GTIII-RS kit and sounds like it should fit with zero modifications. Talk to Hypergear as well, maybe they can do something that fits your requirements.

The maxpeedingrods turbo is cheap and bolts on to stock parts. I think you just need a bigger silicone coupler for the intake. Its a cheap china turbo, but it's been running on mine for almost 3 years at 16-19 psi.

It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible.

Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure.

As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen.

I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon! :D

@Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂 

@joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before)
So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back.
It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" )

@tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo.
I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄

 

 

EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9

I looked at this and it seems ok?
It is that CGC hybrid and it costs around 1250 USD (with back shipping).

Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.

Yes, just without the annoying use of the word hybrid. We stopped using that term 20 years ago when we realised it meant different things to different people. Even "highflow" can represent more than one way of achieving the goal of getting more flow out of a turbo. But at least it says what it does on the box.

Ok thanks 🙂 I will higly consider this.

Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site?

I need to use VPN to even find some of those "shops" let alone access them 🙂

I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date?

Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it.

Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that.

My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).

GCG is a good company, they're a major distributor for Garrett in Japan as well.

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
