Re: N52B25 upgrades
Maybe what jerr is looking for is a description or some numbers on the specific point of failure that is typical in that specific model of engine. Being light and made of X alloy is too general to really examine anything. If there is a specific point of failure (or a few), there might be ways around it (them) that aren't too crazy
That said, sleeving a block (or any other engine machining/building process) is a very precise process to do properly, and sleeving can't solve certain problems.. like if the material supporting the sleeve is too thin, the bores are still going to move around under load, leak, etc. Improperly done, there's always the longevity factor and luck of the draw that can/will bite.

Re: N52B25 upgrades
Geez... how condescending do you need to be?
Since you're going to be so presumptuous & stereotypical.
drawing a broad sweep across the entire forum.
So you've owned 2 cars.
maybe a k20 on your DC5R/FD2R
Or a k20 dropped into your ol' EG6.
So you've have had some experience turbocharging them.
now you feel like the king of the world.
now you need to teach these bmw novices a lesson or two.
is that the way you need to behave?
Why the secretive PM me approach.
this is an open forum.
Where knowledge is shared.
So if you really have so much wisdom to impart.
Please do so on an open plate.
We're all ears...

since u dont understand let me spell it out to you. what im saying is that the basic components of turbocharging and NA internal combustion engine is the same, refer to previous posts.:woottt:
stir kopi and tcss is must have quailty of a towkay though
i'd take ur advise and not waste my time though playing tunes to a cow (chinese saying-cow if not referring to you though in case u get offended again)

Re: N52B25 upgrades
Hey Wilson,
I have BMS PBX on my 323i. But my 323i is Canada version. 200HP stock. So I make 240BHP after BMS PBX, AFE drop-in filter + custom kidney grill air scoop.
Engine bay picture~~
Just rear picture, will take more next time when I lower + better weather... today very bad.
Another picture of HID install

Re: N52B25 upgrades
On dyno from powerbox, it show about 30 crank hp gain.
In Canada 323i is stock 200HP.
So 200HP + 30HP = 230HP.
AFE Pro Dry S drop-in Filter maybe 5HP MAX.
And Performance scoop show about 10HP gain, (RPI SCOOPS).
And I buy MXP Catless header soon!
So I average my car around 240HP.
No dyno yet but next time I will post once i finish headers.
