Hehe send her my regards or "pozdravi" in Bulgarian

Now on topic - the guy replied because he didn't wanna register and here is what I got:

"ESS guys are professionals. They helped me to upgrade my M54B25 to M54B30 and currently I am running my 525i with 3.0l 350 hp (8psi)

Should you go for ESS, my advise is to go for the intercooler stage 2 - a bit more expensive but much more secure in terms of getting your hp in hot weather.

Support is very good, but guys are technical so pls do not get offended for short answers (though very professional)

The car behaves same while cruising but when I push on the throttle it gets wild. I am considering now to buy a Quife diff to make it more responsive Smile

All in all I am happy with my ESS kit but having in mind the cost it might be better to consider replacing your car with 545i (that is up to the personal choice)

And one last thing - should you contact them - pls, do send them my gratefull regards (from Alex Kolev from Sofia)"


On the LSD part - that is my next upgrade. I can give you some information from what I've gathered from them or you can wait until I have it

 

Just watch your gearbox, one of the lads across at E46 forums supercharged his auto 330Ci, blew the gearbox to peices a couple of times, that was on a mild tune as well.

 

Mark he must have been running some PSI to do that, IMO you can be safe with 8PSI and under!!!

 

I remember there was a GROUP BUY few weeks ago for a Supercharger (Active Autowerke) for M54 engines ONLY! If your 530i has that engine (not N54), it is the candidate to get it.

or contact dbpack

BTW it was $4400 the kit.

 

thank you ALL for these rich info.!
I will keep those great suggestion in mind!
can't wait to find a good dealer to put it on!
(i heard autotalent is pretty good..just need to find few more places and compare $!)

 

Watch this, a 3 series with one:


And one i fitted in the S2000:

 

if it really costs $6300.. i wonder - wouldn't it be cheaper to trade you car for 545 or 550? they have 330-360 HP stock

especially now, when used 530 and 545 actually cost the same price. plus u get a lot more options

 

This could be a better option!!!
(and I thought about it too..535i has 300hp already)
and it is not just 6300 as I got a quote:
5900 (the kit) + 1500 (install) !!!
it is just too expensive...

 

Is there one for hte 545 6MT?

 

I am not sure...but check out esstuning.com
