like boostr said many people have hit 230 to 250 whp on the stock block and turbo. your about like me money wise and my 2 things are power and suspension. the stock body is great and the wheels look good no need for appearance upgrades yet. i so far have the following
kw coilovers-1500 but i got em for 1k
turbolife fmic-600
aem cai-130 also go a nice deal on this
unichip-250
pope downpipe-310 very nice piece
i still have to get the vibrant 505 intake manifold and gauges
to answer your question i would go with the tein lowering springs for your drop there nice and cheap. FMIC, TBE (doesnt matter how you do this, custom exhaust is fine too but you want to get rid of the stock downpipe too) cai, turbo manifold (not many makers, steedspeed is probably the best maker for our car also you could go custom) ssafc/unichip your choice. with full bolt ons a tune and upping the boost 230 whp is possible. its not all the motor why these things blow it is also the weak tune. i know of multiple guys who have ran 14 15 psi on the stock motor granted you flirt with danger when upping the boost. 10 psi is considered the highest people would go with some good mods. open it all up before you do up the boost ie fmic tbe youll see a huge change in the car. actually these two things will naturally up your boost to maybe 8 or 9 psi.
