It's a 67x72 I think.. yes, the unison ring gets in the way of bigger turbines.

I don't think the flow bottleneck in these turbos is around the unison ring though, I think it's in the exducer, so increasing that are from 60 to 67mm, with less blades impeding the flow is going to make a really big difference in drive pressures at the top end.. Yes, it might spool a little slower, but I don't think it's going to be terribly noticable... I think after about 50-60% open I won't need to open wide as fast since it flows better.

To start with I'm just going to install the hot side so I can do some comparisons, then install the compressor later.

Is there even enough material left at the exducer @ 67mm ? Or are you just going to machine around the turbine and leave the exiting hole still @ 60mm ?

Yep, there's enough room.. Just at the limit though

OK, I have the parts in my hand now... the compressor wheel is really nice, and a much tighter fit on the shaft than the stock cast wheels.. you have to press it on, or perhaps it would just slide on with some preheating.. anyhow, that's really nice.

Turbine wheel looks really nice as well, BUT, it doesn't have the cut in the shaft for the speed sensor... I put a small one in it with a diamond wheel, I don't think it'll throw the balance off, and being between the bearings it'll be more forgiving that at the end of a shaft anyhow.  All that remains is to install it all.  Injectors first though

It's already installed.. my phone doesn't take pictures worth showing, broke my good phone.. haven't installed the compressor yet though, I can do that super easily with the turbo installed though.. I'll probably take it for a rip tomorrow and see if I have to adjust the vane openings a little now..  The sensor is picking up the notch I put in the shaft, so that's good.

Also, put my old 4x013 injectors back in and my misfire went away thankfully! 

You know your truck rolls coal when you sweep the exhaust off the floor!  That stuck injector sure sooted things up!

OK, I got everything put together.. here's my initial assessment..

It's hard for me to compare EGT's since my 5x012 injectors packed it in last week.. Took it for a quick drive though with my 4x013 injectors, might have to loosen the star wheel a little, has no fuel plate anyhow... it's dark so I can't see what the smoke is like.
It does spool a little slower but I haven't tuned the controller yet, it definitely flows a LOT more air on the hot side.. probably close to double! I do a lot of tooling around in 4th gear (NV5600) on the dirt roads, seems like 10psi boost at 1400 is no problem to get, 1800 I think I can get any amount I want.. 5th gear rolling into it at 2000 it lights the tires and hits 3K pretty damn fast..., EGT's were 1200F
Next Monday I'll have a couple ton behind me in the trailer and I can see how that does.

As for the sound, definitely a lot louder, but it's more of a whoosh than a whine, at least at the power levels I've been asking of it on the dirt.

It took HOURS of machining to do it, I had no specs or anything and a manual lathe, so it was a lot of small cuts and test fitting!
Here's a vid of machining the hot side

new wheel is a 67x89x95

If anyone is interested, I'd be able to do the hot sides quite easily.. I think a lot of gains can be had from that alone.. and I have cores to work with

I would love to do my hot side, how much was the wheel from turbolab ?

It should be noted that it doesn't come with the cut for the VR sensor.. I used a diamond bit in a dremel to put one in

Here's a quick vid I made.. only coarsely tuned, doesn't complain at all about 40+ PSI though the boost gauge does!

Someone put bad ideas in my head... I'm thinking of a strange set of twins.. parallel hot sides and series cold sides using 2 HE351VE's... I think I should be able to make it work but it will take a lot of fiddling.  I need to find another actuator before I can even think about it though... Then modifying an exhaust manifold and doing downpipe work is going to be another adventure... At this point it's just a pipe dream

My idea was just to make a V adapter. Cut the manifold flange off completely. Weld a an outlet sideways with your V cut. So one is up and one is down, angled at your leisure. Then it's as simple as routing a few oil lines, and complicated as a Y pipe to exhaust.

Yeah, that's what I'm thinking as well.. since i have the 4th gen manifold I have on facing down, and I'd put one at a 45* upward, but perhaps moved forward a little bit.

What do you think of the idea of parallel hot sides and series cold sides?  Think it could work?
