Question Would these fit my car?

http://cgi.ebay.com/ebaymotors/Exhau...Q5fAccessories

Hey guys, Would these fit on my 1995 525i? it only says for the E36 M50. I have the M50B25TU.

If it does, then i'm getting some headers

Wow thats interesting . It look s like some custom work to line it up. I like the low rumble of the stock exaust.Might be heat and space issues. http://en.wikipedia.org/wiki/BMW_3-Series

So what would the verdict be? What do you think would need to be done? I have ally of room on the exhaust side of the bay.
Has anyone done eBay headers?

i have friends running fleabay headers wrapped and they have hold good with the wrap for what they are worth. Thing is i have never seen these ^^^ seems to be equal length and i would tell you just wrap them and see how far they get but even the wrapping seems like a challenge as well as fitment

I would suggest Raceland headers, they have been proven to fit in E34s and if you search I'm sure you will find some good info.

$150 on ebay

Would I need to cut into the cat piping though? I think i saw a kit for e34 header installation for like $50. Let me see if I can find it

Probably not much difference unless coupled with a true free flowing intake and free flowing exhaust from the headers back.

I like the way they look and I'm looking for a bit of a different sound. And they're relatively inexpensive.

Yes well im jealous you can find em that cheap. No luck finding headers for my 540. Only company I've found who dies wants 3k for their long tubes. That's pretty damn expensive if you ask me. There's plenty of headers out there for the E34 that are a good fit. Don't remember off the top of my head though.

I was looking more towards shorties that will just bolt onto my cats. I don't want to cut the flanges off of them. A few bolts and a couple gaskets for some nice "snake orgy" lookin bit under the hood. And a different sound would be nice too. Even if it's not very drastic, just a change...

Why don't you try and fab your own? There is a company based here in MN my friend used to make headers for a S10 he swapped a 350 into, they are still on the pricey side.. on their website the quote $1600 to $1900 for stainless... but it beats 3k. Maybe worth at least an email.

Racelands do nothing. None of these headers will do anything but change the exhaust tone a slight, slight bit. The only thing I have heard come from the racelands is that up top, the car pulls a little bit better...but of course that was from the infamous "buttdyno"

OP I wouldn't take a risk with those headers. There are things that 150 dollars could go to that would actually make somewhat of a difference. Start with a chip.

I have a chip. I have a ton of money I've been saving and I am content with my Z. I wanna put some towards my true love, my bimmer. I'm going to do stainless braided brake lines and slotted rotors but I'd like some help going faster cause going slower is covered...

Two words - engine, transmission. Bigger for the former, manual for the latter. Little else that's worth doing speedwise.

Oh yes...one thing you can indeed do for greater top end speed...get s50 camshafts into your engine. $200 ish each, you can get both but the key one is the exhaust cam. This has been a proven mod. Installation is going to be costly but I'm sure you can find someone here who will do it for a reasonable figure.

Lower end torque will be reduced and your idle will be rougher, though.

Roberto, we're going to be friends until my motor is cammed (hopefully past it also) I've done little head work (cleaned injectors/compression test) but I'd like to cam it myself. The only engine I'd want is the 3.5L but id be stretching my finances for that.

Back to the cam. Where would I find these cams. Could used work? Can I do solely exhaust cam? Is there a lighter cam that would work? How in-depth would install be? My motor has ~240k, would this still be wise a mod? I consider myself very competent with motors, and I have an extensive tool set.

Mayr start a new thread for this now that it's OT.

EDIT: An über quick search produced this. Is this simplified to make it look easy? Because I'm sure i could do this. How easy is it to turn until the valves are on pressed on piston 1?
S50 Cams

I've decided to do the S50 cams.
I'll start a new thread about the build when I get all the necessary parts tools. Two questions I have before I bite this monster bullet: What chip would I need to get to be most compatible with the cams? and should I get m3 injectors from an S50 also? I believe they're the purple ones...

Turner not only sells the cams for an arm and a leg, but they sell the chip for an arm and a leg as well. Over at bimmerforums there is an s50 cam turner chip for sale for 125 dollars i think. For best compatibility get a turner chip. They have it down well as far as tuning. As for the injectors, yes you would need to get new bigger injectors. Check that thread i linked you to, they should be in there.

If you can't find s50 cams (which I haven't been able to as of yet) you can also look at s52 cams as well. s52 cams aren't completely compatible but with the cam trays from the s52, you can make them work and there would be exactly the same results.

This info might be useful, and yeah, i think the s50 cams are definitely worth the trouble.

Accumulated this in reading up on the subject over the past month as i'm contemplating the same myself. However, that thread you linked us to is dynamite. Thanks mate !

Is it pointless doing so without an appropriate chip, higher flowing injectors and upgraded intake and exhaust manifolds?

I think the chip is a necessity, although after a few minutes of rough idle and some throttle feathering to keep it alive, the DME should compensate for the larger cams.
As far as the intake and exhaust, a boring the throttle body to match the width of the intake manifold would give you most accurate results and free flowing exhaust to compensate. The E36 M3 uses very similar intake and exhaust manifolds as the M50s. I will be replacing all intake seals and exhaust gaskets when I do the cams.

Also, roberto, sweet info on cams! That will prove useful I'm sure

Well this thread is well and truly jacked but since you're the original poster (op) and you don't seem to mind i guess that's ok.

Yes the cam trays are needed but can the exhaust cam for the s52, which is meant for a double vanos engine, fit a single vanos engine? Will the timing chain fit over it properly? I realise it would fit over the intake cam.

And the exhaust and intake cams seem to be more aggressive on the s52 than on the s50...
