oh geez.. the 2nd gen is a bit smaller than the 3rd.. (obviously) but i'd think the swap would be the same kind of mods you'd do for any swap that isn't the same series... just look it up on another thread in this forum... i had a friend with a 2nd gen.. he did a lot of ish to it... he sold it last year but he was in the process of a jdm b20a swap into it.. it was already realy fast for a 2nd gen Si (beat my car when my car was COMPLETELY stock)
