Important Question - BMW Forum

KevinTS · 08-29-2005, 08:50 PM

Okay I have 92 325i. It has an average of 160,000 miles on the car right now. I am wondering by peoples opinions which would be better. Spend about 4-6 grand on adding stuff to my motor and wait till the motor dies and I will have to start all over again. Or just get a new motor with more horsepower. The same amount of money that I would be spending on parts that pretty much adds up to the same amount of a new motor and the same amount of horsepower that would already be in the brand new engine. Plus longer life of the motor. I know that BMW engines go up to 300,000 or higher. But which would honestly make more sense. I just would like to know what people think.

I personally think it would be a waste to mod that motor. I'm sure it has some pretty decent wear internally. Modding it, will just hurry along the process of that tired litttle motor taking a shit on you one day.

just drop a new block in there man. Ur engine will definetely last longer, but the longevity of your engine won't keep it from starting to deteriorate in all different aspects that will affect your driving.

Much safer of a bet to just put in a new engine, or get another car...

okay so you guys told me to just get a brand new engine. I was thinking about a M3 engine with 333 HP. What do you guys think? Or should I get a different motor? Also what will I need to change when I change motors. I am not going to get the same exact motor that originally came with the car when it first came out. I was thinking more HP. At least 300. What motor can I get that is a good motor. Will I need to change the chassis? Or the ECU? Or anything else. Sorry first time to even think about this. I need to know everything so I know what I am getting myself into. I live in Oklahoma. About 2 hours away from Oklahoma City and Tulsa. Does anyone around here do engine swaps? Or maybe even in Wichita? Or somewhere close to that area.

If you really have an attachment to that car, then go ahead and swap the motor. Or if you keep the same motor, you should at least have it rebuilt before adding stuff. But only if you got cash to burn. Consider that at that mileage, you'll be spending money to replace other things as well- suspension & steering, fuel delivery, and cooling system are gonna swallow a lot of dough. Unless you were smart enough to have taken care of those things already.

if you are not in love with it, i would sell it and find a deal in a newer style/model

or wait till it dies and rebuild .

If you have planned 4 to 6 K to spend on a motor get the s50 motor(3.0 litter 95-96 m3 rated at about 240hp at the crank u.s. model). Its obd-1 like your m50. Its mostly a plug and play swap. s50 is an excelent base for lots of power in the future. You can get a s50 easy for 4K, spend about 2k in suspention, brakes and tires to keep up with the motor.
