M3 Swap Supercharger or Turbo

[Negrodamus]

Ive done quite a bit on my 325is as far as my suspension brakes ect ect..... Now its time to start on the motor. I have a m50 non vanos motor 147k on her . I cant really decide on which route to go so Im asking all of you for your help and expertise in the matter I was contemplating on the M3 swap or supercharger but turbo is also in the works....Give me your ideas

Supercharger I can get another lower milage m50 non vanos motor build it and go from there and install the supercharger


Turbo since the m50 non vanos motor would be a good canidate Im curious to know your take on this wasnt my choice to consider but has anyone done this or know anyone who has?


M3 swap no need to go into details here I would probably go with a mild set up Cams header Exhaust.

M3 swap. No brainer. It starts out with more torque which is what it comes down to. You can see guys pushing out crazy hp but their torque suffers. There is no replacement for displacement.

how about a m52 swap then turbo m52's are making big numbers these days

[Storamin]

but so are the s50 and s52 engines... they're making more power and more torque.

they also cost more and cannot hold as much boost safely. i think card counter on bf.c has the second most powerful car on there other than george at ics at 635whp. thats on a stock m52.

if you were looking fr something nuts out the ass and completely original you should get the M3 swap and find a way to turbocharge it....

That's because he has the best tuning in the nation and balls. Noone else would sacrifice their engien enough to push 25 psi. Do you remember iceman's M3? 600 rwhp and similar torque, and he never pushed it beyond. Unlucky for iceman he got in a car accident and we never got to see what his car would run like with higher boost.


Needless to say the M52 is a great block to wor with for turbochargers, but without ICS's tunign you wont see those numbers on regular m52's.

But lets not forget everyoens top numbers are done on c16. Ulysses's built his car and pushed it at high psi because he knew he would follow up with everythign else. Have you seen all the parts he has ordered? He's looking to completely build the engine. It's nto liek he runs all day at 25 psi + c16. He's got money and he plans to fully build, thats why he took the chance of pushing 25 psi right now. It's probably FAR from reliable in daily driving situations.

Nope. There are a few people in Europ and Australia on bimmerforums who have upwards of 900 rwhp

I thought the ICS guy also had a 1000 or so crank hp M3.

M3 all the way. Great amount of power, has a ton of FI potential, and above all RELIABILITY.
