Not sure where you got this done but you better hope they had a clue.... I'll put a bet on that the deck surface is not totally right, I'll bet if you measure from the crankshaft center line to the deck surface every measurement will be off. The set up time to deck a block is up there. A good machine shop also deburrs all it's work so there are no sharp edges on a deck suface. No shop I know of does the work right for that price. Hell hot tanking alone goes for 40.00 around here...

Since you are posting to a turbo forum, depending on what power you are shooting for, worthless stock LS cams would probably get the job done.

The SiR generation 2 cams, since that's the motor. The specs are pretty decent. Same as the USDM Si althoguh the intake duration is 240 instead of 230. But with boost i don't see why i shouldn't be able to make power above the stock rev limit. I just wanna hit 8500 reliabily (well mostly). Power goal at this point is eventually 300whp on my 48/60 60 trim, although i'll probably swap the housing for a 63 and cross my fingers. Daily i'll just run it low cause i'm a -----.

What you don't know is that stock LS cams have a 230 duration... 240 sounds less than impressive. My LS billets have a 250 duration, meaning I have to live with them all of the time and not just in the upper revs because I have a ****** good idle cam profile, and they hardly fluctuate at 900 rpm idle. It's not much of a duration, and not much lift.
Boost extends camshaft duration. With the T67 on the 2.0/VTEC, there was power at 9500 rpms on stock B16 cams. With a tiny OEM "stage 1" turbine and tiny "stage 1" .48/.63 housing, there probably won't be. You need larger plenum, and larger compressor, to raise your revlimit and have there be any power. The B16 I tuned last week with .50 T3/T04E immediately dropped in power past 8000 rpms, just like stock B16s do, according to Crome DynoTools.

Re: machine work
I have nothing against maxing out a .60 T3's compressor (300+ whp), but I have everything against strangling an engine against that tiny turbine wheel/housing. Compare OEM T3 "stage 1" turbine wheel to the commonplace "stage 3" unit found on the hybrids sometime, you'll see what I mean. It bottlenecks the engine, holds thermal mass against the head + exhaust valves, and you *will* run into problems at some point.
Chris Kelly was running 14 psi on his CRX, with that exact same turbo, and it lasted a good minute (6 months?) before ring land ownage. A bigger turbine and she'd have been fine at those power levels, with no appreciable loss of driveability.
