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
This is a good point. What I was the thinking, was that a modded m3 vs modded 330, m3 would win. But maintenance and cost of upgrades I had not thought of

No doubt the ///M3 would win, but you're also going to be paying MUCH, MUCH more in repairs (when something goes wrong). Hell... an oil change costs nearly $30 more from what I've seen (and that's doing it yourself).

I'd much rather have something I could afford that will spank a slightly modded ///M3 than an ///M3 which I would need to sell my left arm for that would spank a Z06.

^you'll learn someday that its not always best to buy the most badass car off the factory line when you can build one for cheaper

its like when you go shopping for lets say a subaru

sure theres the STI sitting all nice and pretty pretuned from factory with all the goodies
but what about that regular wrx over there thats $8k cheaper(not actual #'s)

if you use the thought pattern
hey i could get the wrx and mod/tune it the way i want with the parts i want and destroy that oh so praised STI and laugh at the people wasted the money on the STI
and still have money left over to do whatever with or save of an in case sh!t happens fund

theres always someone thats going to be faster

just do what makes you happy and content and tell everyone else to eff off

shit i painted my wheels green(2 weeks old brand new) because i wanted to
all my friends were like dont do it
i did it and anyone that see's them in person is like wow

OK. How much does it cost to take an M54 to 300whp? Anyone? Including dyno tuning?

keeping in mind it has similar (less) displacement to the S54, but an M54 (with the aluminum block) can't rev nearly as high. so to get the same power out of it, you have to somehow make a LOT more torque at a lower RPM. Since the S54 is already over 100% VE, I'd like to see how that's possible with a smaller engine that can't rev as high and the head doesn't flow anywhere nearly as well (even modded, there's no way you're going to come close). I'm having a hard time believing it's even possible, without cubic dollars, or that it would live longer than 50,000 miles.

Also, the regular WRXs have crap transmissions. I wouldn't want to run STI power levels through them. Plus you still have to upgrade the brakes, axles, etc, and it won't have the STI center diff, rear diff, etc. etc. It still won't be an STI even if you manage to make it as fast (without destroying the transmission..).

E46 M3s aren't exactly expensive these days, either. they're already almost 3 generations old, they're only goign to get cheaper. I can see if you've already got a nice 330i, that you might want to mod it instead, but if you were starting from scratch...

I only know of one Race Car motor M54B30 that made those WHP numbers, even a little better. But the cost was EXTREME, & it was not what I'd call street-able.

So yes, I'd have to agree with you, 300 N/A WHP on a M54B30 motor is just not realistic. I myself may get close, but that last give or take 30 N/A WHP is not likely obtainable.

It's fun and pretty cool to build something up but if your going for all out performance, starting higher up will help

Lets face it anyone can list off performance parts.

Dyno ?

When someone makes a HP claim like yours, they normally can back it up, can you ?

Also, if your 440 is at the crank, the Dynojet WHP figure (SAE) corrected would be about 361 WHP. On the dyno I do all my tuning on (DynoDynamics) that WHP figure comes down to about 319 WHP. Still a good number, but suddenly; I'm really not that impressed.


Good luck.
