Im in the process of making my track car.
The turbo is 2860RS .86 hotside internally WG with EBC
The motor is a stock 1.6L with mild polishing in the exhaust ports.
Intercooler will be CX racing with 2.5" piping.
Exhaust is full 3" with a muffler and tip
Manifold is Absurdflow design.
ECU is MSpnp
Not sure if this matters but 4.10 torsen rear end
Im hoping to start spooling at 3250 and be @ 10 psi around 4250.
I checked the spool data but i didnt know what housing size they had. Anyway just wondering what i could get away with.

Considering you ganked Tim's design I will regretfully confess that yes, this turbo will probably spin-up by 4k on that shitty motor of yours. My tater with the .86AR on the ~1.9 with 3" exhaust hits 11.5psi at 3100rpm now. I also have a proper wastegate though, which you don't, peasant.

I think 3500rpm on a 1.6 is a stretch. I also seriously doubt an EBC is going to improve spoolage with a proper TiAL wastegate. According to my engineer friend at TiAL the two springs with different free-lengths, different rates, and one preloaded spring is magical.

Here's Jeremy from FM's potato on a 1.6:

he didn't like it. maybe some intake cam advance would help with low end.

I have a larger turbine than a disco, older less-efficient compressor wheel design of the same exact size, journal bearings, and a .48 A/R housing (.64 T2X Equivalent) and I can see 16-18psi around 3500rpm in 4th gear...
This compares my ebay T3 50 trim (blue) to my T3 Super 60 (red)

Im hoping for full spool (10psi) by 4250. If its 4500 or 5k it will be pretty much completely useless for the track (atleast on a 1.6L). With the manifold design (Thank you Turbotim) and uber 3" non restrictive exhaust and some port matching/polishing on the exhaust side im hoping to achieve this.

Did I read that you're going to the Alfa club school?
