I think I have cramp in my face though as it took so long to read!
The info on the m50 mods has been really helpful. I'm not sure what engine I have (it's a 97 328I if anyone can help?) but I found that smoothing out and polishing the throttle body internals made a nice difference, and also completely removing the traction control unit altogether made a difference. It's not such a complex unit and as it works almost exactly like a reverse throttle body I thought that even when inactive it still creates a bit of air flow resistance. Also, if you remove it, it's one less part of the induction than needs to be cleaned.
I did find when I removed it however, you need to leave the connections attached as if you remove them the abs light shows on the dash.
Awesome thread though and thanks to everyone who contributed! I'm new to the site and I think I'll be using a lot of it!

No Sir, the word I was looking for was spelled.








Jus' sayin'.

As to your engine, you have an M52b28.

That was supposed to be touche, I don't know if it showed up on yours but the funny French e didn't on mine.

Also I was looking at exhaust systems prior to finding this thread and I was looking at decat, and here I've seen a few people suggest catback. What's the difference and what are pros and cons? And do you think it's worth doing the whole system including the exhaust manifold?

Re: Mods and upgrades explained - Very Long!!

I'm going to change my shocks and springs on my 1997 328is and I was wondering if I where to lower it 1.5 inches in the front and 1 inch in the rear would it make the handling worse or better?

It will make the handling better in corners it stifins it up so you don't get any roll in the corners and if the back end Duse step out its esear to correct

About to install a Signature Motoring CAI and eventually will get a new exhaust. Unfortunately that's way out of my comfort zone, can anyone tell me the best type of exhaust system to put on my '93 325is?

One you like.

It is ENTIRELY personal preference.

This is one source I used to help choose my UUC System U exhaust.

So how good is the M3's catback exhaust? Are the aftermarket options better? I see some M3 exhausts on craigslist for around $150 bucks which is much cheaper than the other one's i've been looking at. Is getting used worth the price cut if the part is in good condition, or is getting new usually the much better and safer option?

So I'm trying to locate an M50 manifold and it isn't all that easy.
My aunty has a 325 r reg (in the uk, so 96 I think....) would this be an M50 engine? And if it is, will an M52 manifold fit on that, as she is still going to need the car. The obvious power loss aside.
And lastly, is it just the manifold or do the M50 manifolds have a larger bore than the M52?
Thanks.

Just look up pictures of the two manifolds and you should be able to figure out what motor your Aunt has.

Hi Folks,
Just some suggestions to add to the OP (please forgive me, I haven't read all 14 pages!)
- suspension refresh (included for the sake of safety, like brakes currently are). Worn out shocks are bad for roadholding, especially due to ABS
- M50 intake upgrades for M52 cars. Un-strangling the M52 is proven to give good results.

Regards,
Simon

The last I'd bothered looking into this, the dyno results I've seen have shown an M50 manifold on an M52 engine increase top end HP at the sacrifice of low end torque. Fantastic for race cars on the track, but I prefer (especially with my 2.93:1 rear diff) the low end torque for DD duties.

I tend to agree with you, but I'll be doing it anyways, I'm too curious not to do it, plus I think it will fit well with the rest of the stuff I plan to do. I just hope I don't miss that low end torque so much I regret it, I think I would like to feel a little more pull in the higher RPM's though, I find past 4000 its relatively boring. I don't doubt BMW knew what they were doing though, isn't the same M52 manifold on S52 engines?

Yes, like most N/A mods (aside from stroker kits), all the fun happens at the top end. There is a slight reduction in torque, but this can be regained via tuning.

I wouldn't read too much into this, though, since the S52 is a bit of a compromised engine (no offence to anyone, I hope). Its intake doesn't even flow as well as an M50: http://www.motoiq.com/MagazineArticl...MW-E36-M3.aspx

The theory I've heard is that there was some tax or insurance bracket around 190 hp. BMW pegged the M50/M52 engines at this level (no power increases despite variable valve timing, displacement increases, etc) but gave the cars a fatter torque curve to improve performance without increasing peak hp.

I heard the same thing. The before m52 328 was released I heard, anything over 193bhp meant a significant raise in tax fees.

I have also read that a good tube can help regain that low end torque. I hope it's true as I drove 2 hours today to go pick up my new M50 manifold!

I little excited admittedly ha.

Yes I realize it doesn't flow as well as the M50, my point was that the M52 and S52 intake manifolds are the same right? And if so the tax bracket idea doesn't really make sense.

It turns out the M52 and S52 both use the same intake (11611707027). Interesting. How does this relate to the tax bracket theory? I don't understand.

Well if the only purpose of the intake manifold was to keep the 328 under 200hp, then why put it on an engine that has well over 200hp anyways?

I'd bet it's for the increased low down torque.
