PLEASE READ BEFORE U REPLY WITH A STUPID REMARK!!

i have the chance to buy a mint 88 4 door civic ex for $1300 of my freind. Now, my question is. what is the biggest motor that i can put in this car? i just drove my freinds 94 integra and kinda fell in love with it. BUT, i would like to go alot faster then the teg. so if any 1 knows please tell me from what car i could get the engine from and what else would i need, also if possible give me a rough estimate of the cost. doing the work is no problem. i am totaly new to these hondas so please dont give me code names. i dont know **** about em.

thanx
Dan
