From your spec you could be close, it really does depend on your turbo, a cam will also help as it will rev higher & freer. Also the cooler may be on the limit & a 145 main jet is over kill as well.

I made over 200bhp, have a look at my spec, it's at the bottom in my sig, just click on it & have a read of what i've done to get there.

i saw your spec and you are using the piper 285.Does the vernier and the springs really neaded?What about an exhaust manifold like KTR's?
Do you think the standard pistons are good for such boost?

I dont think the pistons is anything to worry about before you want a bit more than 200bhp

If the fueling is set up right then 20-21 psi is ok on standard internals, yes you do need the high lift springs or you run the risk of going coilbound at high rpms, the vernier is only needed if the cam isn't ground well (mainly due to being a regrind) as it can be a few degrees out, if it's a blank then it should be close enough with the standard sprocket.
KTR manifold, as in the tubular ?? Waste of money in my opinion.
