HEY. I have an 86 325es which i am looking 2 sell. i am interested in purchasing either a 91 or 92 318. It changed from e30 to e36 in 92, and i cant choose between body sytles. I am an e30 enthusiast, and i dont know alot about e36's. I am interested in an i or is though. I am looking to performance tune and modify either one, and the only reason i didnt do that 2 my 325es is because of the e engine, and the expensive m20 engine rebuild. I did consider an m50 engine swap also. i dont know which 2 do, the engine swap, the 91 318is or the 92 318 is. If you know some differences/disadvantages/advantges of the 91 as compared 2 the 92 please let me know so i can help decide. also, if anyone knows the highest rated hp listing ( other words the best engine that was produced for the e36 318, please let me know. thanx. nolan
