Building a 325i

M50b25 (2.5l) vs m3?

Okay so I started my build a week ago, as of now I just got the new hawk 5.0 street pads, slotted rotors, have a new suspension kit coming, new wheel set coming (bbs). Borla exhaust(full exhaust/cat back) and I know this is still down the road cause I need other things I need before this but I want to have it planned out, do I just build the 2.5l m50b25? Or do I find an m3 motor and drop it in? I can't decided on what to do, I know the 2.5l doesn't have that much power stock. But if I took it out and built it would it be worth it? Or would it be better to buy an m3 engine build that, for more bang for my buck. The motor I have in my 325i has 200k on it.

S52B30 all the way. It'll get you about three steps further down the performance path right away over the M50B25. Larger displacement, better exhaust and better camming.

Build the 2.5. Everyone and their cousin just does S5X swaps and thinks they are the ****. They ARE awesome, coming from someone with a S52 318ti race car but my M50 3.0L stroker 318ti walks E36 M3's and is unique. Plus it was real cheap to build

You mean S52B32?

I'd like to see the showdown, too. But then again, I've seen 6-cyl swapped compacts with S52 levels of power absolutely mop the floor with standard coupe/sedan body E36 M3s on the track. There's a big weight difference. Depends on the setup and level of spec, though.

the ti (compact) is *much* lighter, so even a stock m52 would be a huge improvement and probably be a blast.

but yeah, depending on the specs, ymmv....

Like Bimmerclause and ZehGerman, I'd like to test that theory as well. ;-) Wanna try it out at Summit Point? VIR? If you want, I can handicap myself and use the 128i first. That car doesn't have a LSD... yet... ;-)

Like with what Karl said I'm sure it has to do with weight primarily and some what with gearing as well. My m3's pretty well gutted so I'm at compact weight
