Custom Sleeves 88mm-90mm (opinions)

[P@]

I just posted this on the sr20deforum.  Im looking for feed back on the
design of some custom sleeves I plan on getting made, to take the bore up to
90mm.  The measurements are english but the metric conversions are as
follows.

A = 105.41 mm
B = 92.25 mm
C = 86.36 mm
D = 133.35 mm
E = 5.08 mm
F = 48.26 mm

With these measurments Ill have 0.103" or so on the wall thickness of the
sleeve when the final boring/honing gets done. I also found an experienced
auto shop in Albuquerque that actually knows what they are doing when it
comes to sleeving a block. Cool.
