Just curious, as to who has the quickest E90 325i/328i/330i on this forum. Please list the year/model/mods/and current mileage.

Also, dyno pics if available. Butt dyno doesn't count

[rick100]

Its not even a contest. BPC's and Digidon have the fastest N52, Both making over 500 WHP last time I checked (somewhere around there). BPC'S is a race car, and the Digidon is more of a street car . Both of them own their own shop , therefore I highly doubt we will see a average joe get there

Then you have the ESS SC guys making just around 275-300 WHP. I believe there are 2 members that actually achieved the 300 whp mark , and there is potential for more as they are not running 3 stage intake

Then you have all the other guys with the header, 3 stage intake , tune combo making around 225-250 whp

Then you have the guys with basic bolts on and tune just making 200-210whp

Then the guys with no tune but just bolts on making around 190-205 whp




But on top , for sure as far as I knows bpc and digidon have taken the n52 to a whole new level.

I definitely don't have the fastest N/A 328 but I have to say I've been quite surprised how fast mine is with some relatively inexpensive mods. I don't think the N/A models are the dog that a lot on here think they are. I have a 2009 MT e92 with:

3.73 Diff swap ($200)
528i 3 stage Manifold Swap ($300)
Charcoal Delete ($0)
BPC Tune ($675)

I used the pro race ap on my phone and got a 0-60 of 5.7 seconds in my car. This might not sound so great but right after this we did a 0-60 in my buddies 300whp MT WRX using my ap. I got 0-60 in 5.1. (His car would typically be 4.5ish but I was driving both cars and my driving style is not a clutch drop kill the equipment style. Also it was 97 degrees on a 90 % humidity August day in Florida.)

I've also some 60-80 pulls around 3.5 seconds in my car.

I believe with headers/exhaust mods, intake mods, and MILV's my N/A N52 could get in the ballpark (within 1/2 second to 60) of a stock 335/e46M3 for acceleration and stay completely reliable for daily driving.

full bolts on will still get beat by stock 335, but you ll put up a better fight. Maybe a win if the other driver doesnt know how to launch . Or one is AWD , AT with a few passenger s

You probably need a SC to beat stock 335.

But its def day and night difference stock vs modded that is for sure. The car feels like a different animal .

Yeah I agree, but I'm not looking to beat those cars. I am enthusiastic that I can get in their ballpark. Honestly I am just really happy with the performance I'm getting from this N/A motor. I bought the car 2 months ago looking for a fun and somewhat reliable daily driver. I wasn't expecting it to perform as good as it does and it really surprised me what a few mods can do with it.

That's pretty damn cheap for a differential ratio change.

I've done it on other cars and unless you're doing the labor, there is no way you can do it for $200 total. The part alone might be $200.

A complete low miles Diff from a 328i automatic was $200 delivered off eBay. It took me about 2 hours to install on jackstands.

Ok, makes sense if you're doing it yourself. I've paid people to do it and it usually costs $700+ total (parts+labor).

I paid for the parts and labor to swap a 3.64 diff into my 330i and it was about $500 all said and done. Worth every penny.

So wrx was 0-60 in 5.1, but what did your 328i manage it in?

Appreciate the post and data point!

[lordbmw]

It's pretty cool you folks managed to get a 328i to 500hp.

My 335i is at around 380hp and I'm pretty happy with that for now. Only real hardware mods I did was a FMIC and chargepipe (after the original blew up).

What N52 is only pushing 190?? I thought the N52 was 215/230 for 325/328 stock.

Whp numbers. A 325i auto might only make 165 - 175 at the wheels.

Since it's quite expensive to measure at the flywheel and quoted manufacturer numbers are somewhat suspect it's best to compare at the wheel numbers.

5.7 seconds in my 328i E92 MT
5.1 seconds in the Modded WRX MT

Same crappy driver, crappy day, and crappy conditions, lol

And I would like to add that AWD creates additional driveline losses. A 325xi with automatic transmission would really be a dog. Funny how many I see on the road in spite of that fact.

[Pidipompi]

I just a slap a M badge and instantly gain +50 hp. You gotta try it.

Nice! Half a second give or take not too shabby.

True, but the target customer for that car wanted a nice badge and AWD. That's probably a large customer base!

Back when these cars were new, they ran very competitive numbers with all other cars and were considered 'sporty'. I do agree, though, it's not a fast car :-0. I'm just glad we can hammer them and for the most part they take it in stride.

[ny325]

Not fast, but fast enough, and enjoyable to drive.

[Efthreeoh]

I have the faster E90 N52.

I agree, my 328i is "fast enough" i.e. faster than the average minivan and 85% of non luxury SUVS and pick up trucks. However where the E90 shines and when we overtake others is around the corners and bends. While all the Acuras Lexuses and the soccer mom vans hit the brakes, we throw it into a corner at full speed with no fuss. The E90 is truly a joy to drive regardless if you have a 325/328/330/ or 335.

P.S. Ever since I got my E90, I seriously drive with no brakes unless I'm coming to a full stop or getting off an exit ramp. The car handles THAT well.
