Anyone heard of Nixspeed Racing? ("CTX" turbos for 3SGTE)?

Hello!
Before starting this thread, I've had a good hard search of forums and the internet in general for any information I can find on Nixspeed racing in the states and can't find very much at all. 
 
https://www.nixspeedracing.com/shop-mkii-mr2/custom-ctx28-bolt-on-turbo
 
They seem to offer a "CTX28" 'bolt-on turbo', with a Garrett core inside. 
 
This is basically exactly what I want, as I am seeking to get my motor rebuilt and then put a Garrett on it and aim for about 250rwkw with upgraded fueling, ECU, and tuning. 
 
Does anyone here have any experience with Nixspeed and/or these turbos?
I'd be interested in anyone's opinions too. I am kind of keen to avoid going with a CT27, maxing out at about 180-200rwkw and being a bit disappointed frankly, so I'm willing to spend the extra dollars to get there. But does anyone think it would be more cost efficient to get this CTX28 series turbo (say just the disco potato GT2860 version) instead of getting a garrett locally but then having to pay someone to do a bunch of custom work to make it work with the Gen2 3SGTE i have. (Note: I'm aware of ATS Racing's adaptor plate but someone told me that it's actually not a good option cause it fouls on the gearbox, and also  their "stealth Kit" would potentially work but it might actually be more expensive in the long run than just this bolt on CTX28 version. Plus i'm keen on a stock looking engine bay and using a much of the stock setup as possible so a bolt on garrett seems amazing). 
 
Thanks in advance for any feedback anyone can give me.

    Extensive experience of Nick Speed. Nick back many years ago released a turbo bolt on, that was no where near his claims. Nick blamed the supplier after heaps being sold and disappeared.

    Nick's claims of the turbo he now sells have again set doubt, initially claiming they are a 550+rwhp turbo, unfortunately Nick had done no testing before selling. His claims of hp have now been revised down. Turbo chra is half of what makes a turbo, ar also impacts how it flows. Now he needs to sell them.

    The Nixspeed turbo is a good turbo for what it is, in places like California you must not change aspects of a vehicle such as turbo, so this turbo appears to be factory. It is the fastest spooling turbo of its kind.

    Challenge with the ctx28 turbo is the price vs outcomes. An ATS Racing Ct27 is a journal bearing turbo at half the costs, spool is said to be a couple hundred rpm later (hearsay as nixspeed turbos dynos are not as vast as ct27 as need to compare based on engine mods), has shown same HP outcomes. As in dynos, real customer dynos (not claims of capability, that's probably correct on a 3ltr but not a 2.0 3sgte). Ats racing ct27 is better bang for buck (remember your import duties on-top of gst costs).

    For the same money as a nixspeed (remembering shipping plus duty and gst hits hard over $1k aussie) you can get adapters and run a genuine GTX turbo or other, having many advantages and flexibility to changes later. The ATS racing adapters are not first time sales, not fowling the gearbox (they have been doing MR2 since early 2000s), someone is misinformed or bought a eBay adapter calling it ats and different turbo to what it's designed for because it's clear as clear for a modern turbo (not a large frame or old td series). As for stealth, check out the ATS Racing Facebook page and they did a gtx3582 on their adapter in a stealth look, seriously can not tell. The same adapter on a $30k USA 5sgte ats racing built motor and you believe that it's fowling the gearbox and the customer says nothing, I am going with it works again.

    For your goals, you are limited to about 24psi on fuel before issues. So assuming you are talking E85 and a 3067 or 3071. Personally adapter from overseas, locally make a dump pipe.

    Thanks Mr T. I really appreciate your response. 
     
    I've been researching this on and off for about two years now, and all i can find is forums and web results full of praise for ATS Racing and their stealth kit, adapter plate, and also their CT27. But I am just hesitant to go the CT27. It's very attractive that it's bolt on and reliable, but i am really keen to make about 250rwkw and not max out at say 200rwkw. From what i've seen, the majority of CT27 results are something like 180-200rwkw max, so I am keen to just bite the bullet and go the Garrett. But then a few big issues plague me:
    1. I had heard the adaptor plate fouls - if that's not true, great news. I think it's seriously back on the table then. Thanks very much for that info. 
    2. The GT3071R that ATS always praise on their website and in forums just feels like it's going to be too big and too laggy. I would probably be more interested in either a GTX2867R or a new G25-550 (expensive oof) over a 250rwkw 3071 lag monster - i think either of those two turbos might make the power goal AND spool better. If a disco potato can do 250rwkw i'll be surprised, but i'd be willing to sacrifice a little bit up top if it can do it and be super responsive (e.g. if it could make say 235, i'd be happy with that). But that being said, they are the experts and i get the feeling it's all about the exhaust housing A/R - with a 0.63 A/R the GT3071 might actually be fairly responsive...
     
    Anyway, all of that is why i was so interested in nixspeed racing. He seemed to have a bolt-on housing that would hold a GT2860RS or GTX2867R, and these were very attractive to me. 
    But i totally take your points above, and look if the adaptor plate will work i think i'll probably just do that. 
     
    I did speak to the guy at Nixspeed via facebook, and he was also plugging the CTXona turbo, which I was a bit less interested in cause it seems to be a higher power turbo that would be too laggy and inefficient for my goals, plus i know nothing about Xona turbos whereas I'm comfortable with Garrett's reputation. 
     
    I suppose the other thing I haven't considered is flex fuel tune with E85 and a CT27. I assume maybe on E85 a CT27 would make the 250rwkw mark. Maybe that would actually be more cost efficient than a Garrett?

    If you wanted a reliable, streetable, spooly 250rwkw 3SGTE, what would you do?
     
    Thanks for your input btw, i really appreciate it.

    Goals, budget, reality of technology, parts lists mix / recipe, a balancing act.

    Lots of discussion as to if / how (parts list) your 3sgte can sustain the hp for a great 250rwkw powerband at good power-to-weight.

    The smaller turbo gtx28 has more response but relies on E85 for powerband, larger turbo gtx30 sacrifices some of response but more powerband on fuel and E85, G25 is the best of both but expensive - refer maps. And everyone wants a little more after doing something, hence back to gtx30 series as a broad guess without details.

    I would do... Different recipes... E85 vs 98 Ron fuel, stand alone ecu / piggyback / stock, add rpm, engine in vs engine out, your mechanically minded or not (who's doing the work), where you live (Cairns humidity or Jindabyne altitude or beaches of Melbourne).

    Powerband is more key to continuing smiles than peak dyno queen that's short lived smiles.

    Chat another day.

    ok, so far my plan is something like this:
     
    Overall Goal: Responsive, reliable, 250rwkw (~335rwhp) 3SGTE that is built to make more so that it'll be reliable for a long time. 
     
    1. Full engine rebuild by professional (I have a particular shop lined up for this job) ~$10k
    - CP Pistons
    - Manley rods
    - ARP Head studs
    - Cometic head gasket
    - upgraded oil pump. 
    - Upgraded cams while we're at it if that's required for my goal (perhaps 264? I've read that's a reasonable middle road of cams for this sort of power)
     
    2. Haltech ECU installed by the same professional ~$2k
     
    Bits I can source and install myself/ with help of mates (and hoist):
    3. Fuel pump ~$150 (Walbro 260lph? Bosch 040? Supra pump? I dont know yet, whatever is most reliable)
    4. Fuel injectors x4 $600 (My XR6 Turbo has ID1000s - they're brilliant, so I'd be inclined to stick with brands i trust. Plus I've done the injector calcs - at ~20psi from the turbo, 1000cc injectors support 450rwhp on E85 max, and more on RON98. I plan to keep the car running on 98 at least in the foreseeable future, but with these injectors there's room to go to E85 and make heaps of power in far future if i wanted to)
    5. Top feed Fuel rail ~$300 (ATS seem to make one that'll take ID injectors)
    Actually I just noticed ATS have a full top feed fuel kit for like $1200 AUD.
     
    6. Turbo Options
    - GT2860RS: ~$1800
    Pros- well tested, reliable, spools fast. 
    Cons- might struggle to make more than about 200rwkw with my planned setup.
    - GTX2867 Gen II ~$2500
    Pros- new design, make more up top but maintain fast spool. 
    Cons- still runs the 28 sized exhaust housing, so will also be restricted around the 200rwkw mark? also, not much info on the internet of 3SGTE results with this turbo. Also, quite expensive.
    - GT3071 ~$1800
    Pros- the most well-documented aftermarket turbo for a 3sgte that will make my power goal. 
    Cons- might be too big, spool slow and make a big peak number at the high rev range that i never use. 
    - G25-550 ~$3000
    Pros- seems to possibly be God's second best gift to planet Earth. can make one million horsepower and spools faster than the Millennium Falcon. 
    Cons- expensive. no MR2 results I can find on the internet. Would it need a bunch of custom pipework? 
     
    Things my car already has:
    - Aftermarket side mount intercooler (i've read this really will still be fine up to my goals. I'll consider running water injection if cooling becomes a problem. Melbourne has cool-ish nights 75% of the year)
    - Aftermarket exhaust. I think it's 3". I assume the dump pipe will have to change with the new turbo, but if i keep it internal gate i dont have to do external gates and everything is a bit more simple no?
    - Apexi intake (not sure if this is even worth mentioning lol. Probably will need a bigger pod filter anyway)
    - GFB electronic boost controller (- currently on 10psi but with a faster ramp up it makes 149rwkw)
    - The engine is tired. leak down and compression test show that it needs a rebuild anyway if i'm going to make any more kws. 
     
    7. Dyno Tune - same shop who did the rebuild and the Haltech will be the #1 choice tuner for the car. 
     
    8. Things i'll need after it's tuned and I realise how many things i've forgotten to do lol:
    - Heavy duty clutch 
    - wider wheels, bigger tires (currently only on Work Rezax 17x8s and 225 rubber on the back)
     
     
    Other important things I've read and assumptions i'm making (which may be wrong):
    - The stock ignition system will be fine
    - The stock AFM will be ok with this new setup, albeit a bit restrictive? (Or do I need to go to a MAP sensor?)
    - Stock 
     
     
    Probably going to cost close to $20k for all this.
    Am I dreaming? 
    What am I missing? Where are my assumptions wrong?
     
    Should I just settle for say 200rwkw and save A LOT of money? (e.g. a CT27 or CT21, upgraded fueling and a Haltech, and a mild rebuild just with head studs and metal head gasket, and i'd probably cut the bill literally in half?) 
    Is that extra 50rwkw worth it? 
    Or would some sort of halfway shopping list between these two extremes meet my goals using a CT21?
     
    All opinions and comments welcome. Thank you for reading.

    I can't comment on the end results as I haven't driven it with the new turbo, but I got a CT27 new from ATS that had an issue with either the compressor or turbine hitting the housing when cold. Fault was never determined, but after GCG repaired it and did whatever mods it added, it lost the CT27's ability to rev vs a CT26. After deciding to address hot inlet air temps at the source I went with a GTX2860R Gen 2. ATS didn't have any adaptor plates in stock, so recommended me to Nixspeed, saying they'd heard good things, but never tested it. Garrett claims the Gen 2 will support much more power than I'm after, so the size is sufficient for what I'm after.

    The Nixspeed wastegate flap will hit an ATS downpipe before reaching its limit of motion, my mechanic got the downpipe modified.

    I noted that the investment in turbo development is much greater on the compressor side, so I noted that when getting a 'backyard' turbine housing.

    What sort of power are you after?
    Have you had your motor rebuilt and if so forged internals? 
    I'd be interested to hear your specs. 
     
    MrtT MR2 (replied above) has been giving me some really good options to think through re: if forging internals, why not go 2.2 stroker, and if so, why not consider 5S block etc. I am still just researching and saving my bickies. But the Nixspeed option still is on the table for me, and it might be a good bang for buck setup for me to make my ~250rwkw goal if I get the supporting mods right. 
     
    Also, when you said "I noted that the investment in turbo development is much greater on the compressor side, so I noted that when getting a 'backyard' turbine housing." do you mean that you think Nixspeed's turbine housing is a bit of a backyard design and might not flow well? I've kind of gotten the impression from talking to Nick (from Nixspeed) that the Garrett GT28 sized turbines themselves are actually the restriction, that's why his CTXona option might be better.

    The backyard comment was a little throwaway, but I have no idea what flow testing Nick has done, or what tolerances he has with the turbine housing. The Xona turbine rotor, with its long and short blades may be an improvement. The few reviews I've seen are positive, but I don't know if they are truly unbiased, and what the experience base is.

    After reading about cracked stainless steel manifolds, plus the need to do additional exhaust work to join the different turbo location, I decided the ATS stealth style suited, but the plates were unavailable. Plus the Nixspeed housing saves a gasket join, and buying a supercore can save you money.

    I'm not going for big power - I don't have a number, more looking for a feeling, plus enough of a gain to justify some of the $ I've put in. The only internal thing I've changed is fitting 3SGE Gen 2 cams, which have 244 vs 236 duration and 0.3 mm more lift.

    Going to 2.2 gives you 10% gas to spool the turbo, so it helps you run a bigger turbo. My block is the original, from a March 1991, so I'm well before the weak block issues. And I've only got 98k km on the car, mostly in stock condition.

    I've got the Adaptronic ECU, which has been on since 2017, and will be going coil on plug. I've got a Walbro 255 l/h pump, Wolfkatz side feed fuel rail, 660cc Aisin injectors (a Supra upgrade). I'm not looking to run E85.

    I am looking to run a mild water injection system, which started mostly as an additional intercooling measure. The rest of the intake consists of the RacerX airbox, to the Garrett, then the MR2 carbon fibre pipes, side mount intercooler with 9" fan, ATS throttle body, stock TVIS intake (to be controlled by a separate RPM switch to the Adaptronic).

    I'm giving my mechanic further work by giving him a Turbosmart Gen V wastegate. (Looking at 1.2 bar max boost.) These are only made for Borg Warner EFR turbos at the moment. I just thought better boost control would be available. Additionally, I'm looking to get an engineering certificate once it is done, so passing an IM240 is part of the plan.

    My exhaust is a mix of ATS, KO Racing (who included an HJS cat) and generic one in two out muffler in the stock location.

    All up, probably a set up never to be repeated.

    Cheers,
    Martin
