Hi, I have a 92' 325is with a M50 non-vanos engine. I am looking for some advice on if there is anything I can even do to this engine. I have already tried a dinan chip and it was fine but was not satisfying enough for me. Being a non-vanos I am having trouble figuring out if there is anything i can do to the engine that will add major power increase. I don't want to put a supercharger or turbo kit on it, all motor is what I would want to do. Any opinions?

Well i am not an Bmw owner but i will be!!!
By the end of this year i will get a 95' 325is or MAYBE a 96-97' 328is.
I know almost everithing about theme already.

SO in your case i think u can swap an M3 engine out of a junkyard (if it is easy to do. I don't know yet).
But, your car is pretty much awsome! be proud of it. It is not a race car. (^&*% Why not????) .Even thougnt i am interested to see what everybody else say about this.



well see ya!

You can always do the generic thing. New intake exhaust. Nitrous(its not as dangrous as you thingk). Turbo the car.

You need to find a vanos unit and the DME off a 94 525i and swap
"if you have any more ??? mike@autohausbayern.com"
All I do are engine upgrades, the engine you have now has diff pistons and stronger rods so it can take a lot more power your problem is
@ low end now but vanos will halp in the middle and top end of your power band. (( Is that the problem ??? )) e-mail me for any ?
