on the HKS website it still says it comes as a kit, but I think the Kai version is now using the twin scroll version...

slight power increase going by what the translated HKs page says...

I have a used HKS2835pros turbo for sale with exhaust flange if your interested

The 2835 has always confused me slightly, its seems so close to the GT-RS that its place in the market isn't really required? They share the same compressor wheel, with a slightly bigger rear housing correct? Obviously HKS's graph proves the difference between the kits is minimal, to say the least.

I would actually say by looking at the graph that the GT-RS is redundant...

But also the difference between the pros and kai is pretty much nothing in performance, the kai should whistle like a bitch with that front cover though

The Pro S is close to the RS, but seems to have a marginally bigger top end. It is squeezing in between the RS and the 3037 in the HKS range. All three have been around now for quite a few years.

The Pro is the difference, external WG etc etc.

Not sure if you can still get the Pro now though?

I agree, judging by the graph the GT-RS should be dead in the water.

As far as I know no one is doing a "T3" flanged twin scroll twin integral gate turbo so far .

I doubt this situation will last forever since Mitsy has done so well with turbos like this , except in their own flange pattern . Actually HKS is now doing a bolt on BB TS TIG turbo for the Evos 4-9 and its supposed to be a nice if expensive unit .

It looks to me like Garrett is being left behind with wheel designs and trims and it remains to be seen if they'll do anything about it . Slightly larger wheels and or smaller trims is working better for the other turbocharger manufacturers and when you throw in TS turbine housings and port shrouded compressor housings they can be wider ranging things .

A .

You wouldn't happen to know if there's any difference in specs? Externally it just looks like there's anti surge slots, and that's about it!

Assuming you are friends with the OP, did the KAI come with a dump or is it an OEM bolt up scenario?

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • 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).
    • 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 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
