E30 M20b20

[a-boo]

hi there,i have a question on this particular e30 engine, i would like to know is it advisable to add HP :a) change the throttle body to 2.5"? b) or just rebore the original throttle body to 2.5"?c) Upgrade my current extractor to a custom one? For question (c) i heard that a new custom extractor will be more hotter than the stock ones yet better flow ofcourse but it will melt seals around the engine. please advice me sifus. thanks!
