Naturally aspirated... not much. Maybe 220whp maximum. FI can get you to 300 and beyond depending on how much $ you're willing to spend

That's not true. I'm at just under 240whp pretty easily. I don't think 260 is out of reach with head work.

Active Autowerke Stage 2 supercharger kit is a claimed 405 HP, if I remember correctly. Naturally aspirated, you could probably get somewhere in the 250-300 range with proper tuning and upgraded internals.

Hell... The S54 cranks out 333 HP with only 0.2L more displacement. I'd say it's very possible to do this with the M54 motor... just depends on what you want to spend.

Not to mention if you wanted those extra .2L you could easly bore out the block. But Im not sure how well these motors enjoy that.

Although I did just see aggie sig and it says maxbore....Idk if that means bored out to the max or just a brand name

On the dyno I use (DynoDynamics) a Bone Stock E46 M3 dyno's in at 247 WHP, give or take very few

So seeing E46 M3 WHP numbers with a 330Ci/i are quite possible, but you will need to spend $ to achieve it.

As to boring out the M54B30 block, you can only go about .5mm / 0.020" over.

Good luck.

So theoretically my 330 can be a monster, it just takes cash hahahaha. what would you guys recomend for a few quick upgrades like exhaust etc, from what i can see bmw have built a pretty wiked exhaust already, is there much room for improvement in headers or anything?

if you want 250-300whp n/a, wouldn't an S54 swap actually be cheaper?

I mean, the first 95% of an engine is easy/cheap, but the last 5% gets exponentially more expensive. how many thousands would a 300whp, n/a M54 cost? how long would it live?

My 3 inch single made 6whp over a Magnaflow catback.

Long tube intake, headers, exhaust, cams. Different car. Oh, it'll be really loud.

the price for headwork really isnt as bad as it seems

sure you can get more power with f/i at about the same as headwork and cams(if you diy everything and varying on how much headwork)

but a nice roar from n/a sounds soooo appealing/good

yer i agree, im a massive fan of n/a horse power, but a nice super charger wine would also be nice.

by the time you got to 300 whp (or even at the crank) n/a, wouldnt it be more cost savy to just buy an m3? trade in your car+cash you would spend in total to mod it,, and you could prob have something with an s54 in it from the factory!.......

and then youd spend twice as much to mod it
and twice as much to maintain it

ill keep my 330 mod it to my content and possible rip an somewhat stockish E46 M3 a new a$$hole

my 2 cents

s/c for 330 $4695

s/c for M3 $8695

same company stage 1 kit

whats the fastest e46 M3 out there right now
not even 10 sec in the 1/4
and thats hpf'd the fu(k out so like $20k +

look at pei330's car (sorry dont know your real name)
i think he's pretty much bitch smacked any M3
n/a with nitrous for cheaper possibly in his final configuration kinda

granted more than half of his things are one off but he and others paved the n/a ground for anyone
and if he shared(not saying he wouldnt) the info on what it takes to get there im almost sure that youd see alot of 330's all of a sudden beating up M3's on the regular
because all the leg work and trial's and r& d has been done by him and others all ready

all the information one could need is here on the boards
hidden somewhat yes to a certain few
maybe if people ask nice they will share their knowledge
