Hit up MTQ. I got Nismo 3.2ish's 8374/1.05 for a tad over $3k, delivered. That was in January. It was 1 of 2 I could find in the country at the time. No one had stock.

Hey mate are you messaging MTQ directly? If i follow the links to sonic performance im seeing 3.5k?

Cheers

 

Maybe they had a price rise?

 

- The twin gates for starters

- The fab work for the twin gates. Less if you want screamers, more if you want to plumb them in. It's a time consuming job.

- The braided lines to each gate. You can go as basic or as hard as you want here. Single 3 port or duel 4 port MAC valves. The lines are not cheap!

I'm after an 8374, oh wow that's cheap. Gcg sells them for $3800.

I'll suss out turbo dynamics. Is that aus dollar $2400?

Hit up Hybrid Turbos, hybrid turbos and turbo dynamics are the same company but turbo dynamics list the 8374 external gate as sold out. :huh:

$2400 Australian dollars for my turbo, the 8374 would be under $3k delivered to your door.

Do the iwg versions make the same numbers as the ewg ones? 

I think sub boy made an extra 20 kw by going from a 0.92 to a 1.05 on a 8374/rb30.

Okay time to chime in here. Thoughts on a 6758 .80 A/R T4 twinscroll on an RB20 with T4 twinscroll manifold? I was thinking 6758 but in the "old EFR thread" people kept banging on about the 7163 being the magic unicorn of the B1 frame size. I'm looking to make a responsive 220-230ish kw on 98 octane and then feed it E85 and make as much power as possible.

I think a 6758 is the best choice unless someone can give me more of an idea about why the 7163 is supposed to be so good?

Thanks

the answer is "it depends" -- engine displacement, boost level, max engine rpm, VE and altitude will all have an effect on backpressure and "the numbers"

both are good turbos.  7163 is typically much more popular because when run in twinscroll config -  the spool is similar to 6758 with much more airflow.

Can anyone offer more info on the 'mixed flow' turbine and it's advantages?

the mixed flow turbine wheel in the 7163 has higher strength and lower inertia than an equivalent radial turbine wheel.  Interestingly the mixed flow aero did not work nearly as well when it was scaled up to the larger wheel sizes

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
