all in all you probably wont win, shy of spending some big bucks, without some dirty methonds, i guess we here are good witht eh dirty methonds.

 

i drove my buddies 07 Si, and wow, its soooo nice. super fast and it handles like crazy. defintly gunna get one once my car is payed off haha i LOVE it!

 

i doubt ull be able to take down that 07 si without some major mods all is ur lx an auto or a stick a stick would be alot better in ur hopes of takin him down but without some major cash ull have no chance even boosted at like 8 psi on stock internals i doubt u would stand a chance

 

A mini-me swap. That's putting, for your year, a y8 head on your y7 giving it vtec.

 

considering i have an 07 si...all these dirty methods are just not nice...lol...i wont even go in my car if im sweaty becasue i dont want to mess up the seats...let alone greasing clutch pedals and effin up the seats and alarms...j/k..

with that said, i had a slightly modded 95 integra ls which had a slightly larger motor than your civic, and the si is a differnt league...you will need boost and lots of it to take down an si...not to say you shouldnt try, im not trying to gloat or anything...but money will most likly be a factor in the engine build.

good luck!
