Engine mod/replacement?

i have a 2002 PT cruiser. laugh at me later, i loved the car. but my engine is prety much shot. needless to say i was careless in a situation where i should have used beter jedgement. but i'm looking forward to making it more of a hot rod once i get he money for a new engine. and i've targeted the 3.4L LQ1 to throw in it, since the motor is designed for front wheel drive cars. everything i've read on it says the motor is "tall" now my Pt's 4 cyl was pretty frickin big, but this engine is a full cubic inch larger. could the 3.4l be mounted in the PT with minimal structural mods?
