Newbie with an imagination and nothing else but!

Hi, folks!

My nickname is Leo71 and I am a proud owner of a 1994 Honda Accord stationwagon.

Please keep in mind that I don't even know nothing about cars but I do have ideas on what upgrades I need for my car!

It currently has a 16Valve engine but I need a bit of 'spunk'!. I was thinking of changing it to an accord-vtec engine from a later Accord model or form a Prelude.

Is there a better method than that? Does various weight of the engines change the overall performance of the car? What precautions should I take if I am going to go head with it?

Your suggestions will be appreciated.
