Was told by the people at shop that the op6 rb25neo would be to big for my rb20det?

Well, there's no way that that's true, because that's a stock turbo for a barely bigger engine and you can put substantially larger turbos than that on an RB20.

The NeoOP6 is good for maybe 200rwkW on a 25, possibly more or less on a 20 (probably less). They really don't spool up a lot more lazily than the stock RB20 shitter turbo, so it's all win win....if you can find a good one, and if you are prepared to continue to live with a ceramic turbine that could fall off the shaft at the changing of the season.

I have seen near stock (internals, etc) RB20s make >260rwkW on big turbos that come on like a light switch at 4500rpm or so. The happy medium is somewhere in the low 200s I think.

If you want a new turbo, or to perhaps highflow your existing one, look at Hypergear.

I put an OP6 in my full stock (including exhaust) RB20DET back in the days, was great. A little laggier than standard but hammered to redline. Being a bit more laggier meant daily driving returned better fuel economy.

Also, look in here:

There's a Hypergear turbo dev thread in the next page, another option for you.

I just ran some injector cleaner through her. started roughly the first time after adding it but gave it the beans slowly upto 4k, Must have cleaned a few cobwebs out. another step in the right direction for the sub

      Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in

      Let's just fix the problem by f**king the rest of the gearbox.

      Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
