Dear safwan....no need to feel sorry for yourself for not having an E30 with M20 engine. Indeed u are feeling better with ur RB20DE engine, but I remembered u used to tell me once that you wish to drive an E30 with M20 engine. Nevermind I will bring u around KL when u come over here, some of my friends whom have restored their E30 back to pristine condition. Have one in Subang Jaya, a 323i still using its original engine + automatic box and the car is as smooth as though it had just being delivered from Auto Bavaria. Plus surprisingly, the cost to maintain the engine is not as bad as what we thought it used to be Safwan.
