Quick one for you guys with larger hotsides. I'm fitting a modified 0.63 a/r Garrett hotside to my HX35 and as you can see in this photo, a little clearancing will need to be done for the turbo to be clocked right:
What are the recommendations here, as far as which tools to use, and the feasibility of doing this mod without opening up the oiling passages to atmosphere?
Interesting thought. I'd also need to move the intake manifold up with a spacer for clearance - it's very tight as-is. Is there something recommended off-the-shelf, or is there a fair amount of material I can safely take off the bottom? It's the flange where it meets the throttle body, if I remember right. I've been away from the cars for a few weeks.
Vband probably, with an aftermarket downpipe. I can add a thicker gasket/spacer between the DP and the rest of the exhaust possibly to make up for the delta.
HX35s? Upward of 500bhp on the stock 16cm housing I got with it. With this housing, probably closer to 450bhp, just spitballing. It's a great spooling turbo as long as you have a well-matched hotside. This is equivalent to a ~9cm housing, it's 0.63 a/r. Turbine wheel is 60x70mm. Based on other reports, I should be making full boost by 3400-3800 rpm. I'm shooting for 350bhp for now as a starting point.
Any particular materials I should target for the turbo spacer? Aluminum probably? My plan is to stack washers under it until I can clock it correctly, then use that height as the basis.
When you say "bhp" do you mean 350 at the crank? because if so, there are about a zillion other turbos on the market that will hit that number without the massive amount of custom fab work that you're talking about. even if you're talking 350 wheel, I'm not sure you're really making enough power to justify the work based on what's available....... unless you just like doing the fab work. It seems like reinventing the wheel to me.
I'd get a spacer for the turbo and intake manifold.
Alum should be fine...intake you could try a phenolic for ****s and grins.
I'll sell you one
I'll bite. How much for the manifold spacer?

350 at the crank is a starting point while I tune. The amount of fab work isn't crazy. I can use an off-the-shelf V-band downpipe and simply have a T3 flange welded onto my crossover locally. The spool on a Holset puts any KKK turbo to shame and the hotsides flow very well. I can go to 400whp without having to change the turbo, if I ever wanted to. And these are available all day long for cheap. I don't see the big issue, there's a reason DSM guys love them.
grind the right side where the housing is touching and grind the fins off the mount in near the center cartridge area of the turbo charger,
Only grind what is needed for clearance.

The 7 blade HX35 compressor that Michael and I are both running flows 60 lb/min. The .63 housing MIGHT not be big enough to see that peak performance but DSM guys are logging 50+ lb/min with the same wheels inside a .55 housing so there is definitely 500+ rwhp potential in the compressor and turbine combo. It outperforms a GT35R at any boost level a 951 would run. Yet, they outspool a K27/8. The performance/dollar available in these holsets is impressive. I am trying to build a fast spooling 400 whp setup, and I think the hx35 is the best option.

Grinding the stock turbo mount
