You can still upgrade the intake manifold, get a more aggressive camshaft (not really a bolt-on, more a bolt-in) and an adjustable cam gear, then tune the hell out of it. You can probably get close to 150whp if you're lucky.
There are two that eat up most of the market on the D series- the Skunk2 and the Edelbrock Victor-X. Most people accept the Victor-X as being better for high flow setups like forced induction, and the Skunk2 for all motor apps. Do some research. There are probably more options out there now too.
150whp would require REALLY good tuning. It's doable without going inside the block, but unlikely.... although you can get close... maybe. 150whp means a 50hp gain at the crank. Now I think about it, that's pretty damn optimistic. Maybe 140? Who knows. Good luck.
