Have experience with the 62mm version fitted into a crappy ill-machined chinese .63 undivided housing.

RB25DET neo stock engine was approx 400kww on 98 around 27psi.

Forged bottom end and light porting became more det limited as comp crept up a tad and was approx 380kww on 98 then 470kww

on E78 approx 32 psi. Awesome turbo. With decent housing would be even better. If you want more chuck the KTS upgrad wheel on.

Have dyno sheets if wanted.

Hi there ?

Anyone have experience with Garrett GTW turbo's? I'm going to buy GTW3684R with 0.70 T4 divided exhaust side. Hope it will spool like GT3582R with 0.84 T4 divided and make at least 50 horsepower more?

Will be interesting to see how that goes, it's a bigger turbo than a GT3582R running a T-series turbine so I'd not necessarily count on better response but post results when you get it going.

Here is 25 neo GTW (Red) vs 3 Litre GTR head w cams etc Holset HCR40rs (Blue ) (supposed 650 kw hub)

 

HRC40RS making 650kw @ hubs?  Crikey, I use hub dynos and that sounds ambitious to me - though I'd hope that the claim there was at least on higher boost than the 18psi in this comparsion?

The GTW3684R is a 62mm, but the GTW3884R has a 62mm option as well - do you know which was used in this comparison?

Don't think response will be far off in the proposed turbine housing. Will certainly make more power.

 

Just what the customer was told and told me.

 

Was a 3684R 62mm.

      Definitely a good “future upgrade” option if you plan on keeping the car and dialing it in even further.

      Nismo GT Pro LSD configurations

      No, you're wrong, and you've always been wrong about this. The Nismo has 2 sets of openings. One is a real 2-way, and the other is a 1-way. There is no 1.5-way possible with the ramps that they offer. A real 1.5-way does exist. That Cusco stuff I posted is a prime example. If the forward drive ramps are, say 55°, and the overrun ramps are, say, 30°, then you will get about half as much LSD effect on overrun than you do on drive. It is real, it realy works. OK, you're slightly right. The Nismo has 55° and 45° ramps on the 2-way, so it does offer less LSD effect on overrun. But, I think that just means that they've (probably) sensibly established that you do not want actually equal LSD effect on overrun. You just want "quite a lot, but not quite as much as the drive LSD effect".

      Yea, that is what I was getting at in my ramblings too. The nismo one actually is a 1.5 way and a 1 way. They don't do a *2* way because a true *2* way would have equal ramp angles. Or is that a true 1.5 way? Realistically I think a "1.5 way" does not actually exist. A diff can either lock in two directions or one. It also doesn't help that a LOT of people in Australia speak about 1.5 way diffs are referring to their 1 way diff.
