The M50 intake manifold can be found off of E34 and E36 OBDI M50 motors (maybe 92 or earlier - 95 525i and 92-95 325i), as well as S50 from '95 M3. There are two versions i think - earlier (pre-M50TU VANOS?) is a bit different than the later ones but supposedly they all work - although I think the later ones are more desirable for some reason I can't recall. That's off the top of my head - could do a bit of research and find the exact range of donor M50 cars. Most junkyards seem to know that the M50 manifolds are in some demand as a performance upgrade and charge a premium over what you'd think a dusty 12+ years old plastic intake manifold should cost. Most of the ones I saw sold for about $200 and even more. You can find them on ebay too. I got one on ebay from an S50 for about $105 which seemed relatively reasonable. I used the Eurosport adapter kit for mine earlier this year. It is a bit pricey but all-inclusive and a clean install. marty '96 M3 with S50 intake manifold and Eurosport adapter '95 540i-6 with BMW M60 intake manifold mdriver13@aol.com wrote: > Date: Tue, 10 Jul 2007 11:05:47 -0400 > From: mdriver13@aol.com > Subject: Re: [E36M3] replacing intake manifold? > > Not totally sure, but I think the M50 manfold itself can be found in junkyards off?a e28 535 series car?? > > > Bob Gill > 97 ///M3 coupe > Philly Region SCCA > 2005/2006 Philly Region BSP Champion > Sponsored by WCC & Rogue Engineering > ************************************************* Please help support the E36M3 list by visiting our sponsors: Bimmerworld http://www.bimmerworld.com Turner Motorsport http://www.turnermotorsport.com Eurosport High Performance http://www.eurosporthighperformance.com Rogue Engineering http://www.rogueengineering.com Treehouse Racing http://www.treehouseracing.com Elephant Motorsports Inc. http://www.elephantmotorsports.com DIGEST INFORMATION: http://www.bmw-m.net/resources/digest_info.htm *************************************************

While I have no personal experience to draw from, I've heard good reports with regard to the Eurosport kit also. Again reported here and local to my BMW Chapter, you will need to get cams to 'cover-up' the 'hole' in the HP/Torque curve created by this manifold. I have seen the curves overlaid, for stock and with manifold mod, and there is a bunch of 'area' missing with just the manifold mod.

My lifters aren't really noisy, but I'm considering doing them. Springs are also high on the list of must do.

Motor has never been 'zinged', as far as I know. Is the machine shop capable of determining the condition of the valves and recommending replacement or regrinding? - Larry

I'm very happy with mine which is essentially the same as Marty's. Junkyard M50 intake (~$100) + the Eurosport kit. I have a couple of other things like no clutch driven fan and underdrive pulleys so that *may* affect things a bit. If I get into stockish 95 M3s and drive I'm always wondering where the power is. :-) Carlos 98 M3

There is definitely a loss of torque on the low end (below 4000 rpms). This loss of torque is why I waited to do this modification until I was ready to do cams (+Software/supporting mods). -Ben

Date: Tue, 10 Jul 2007 13:17:01 -0400 From: marty <mfraiser@earthlink.net> Subject: Re: [E36M3] replacing intake manifold? yes, i am happy with the results. I installed the Conforti CAI and removed the ASC throttle body at the same time. Still has stock air flow meter, throttle body, injectors, and cams. It has base Shark s/w it's had for years. It did seem to lose a bit of torque at lower rpms (3-4.5K maybe) but a definite improvement from around 5K to redline. While the power used to sort of peak around 5.5K, stay nearly flat, and decline near redline it now climbs through that range. Found myself hitting the rev limiter some until I got used to it. I think I was waiting for the power to drop off to shift but it doesn't drop off any more :) Plus the sound was different with the CAI so couldn't use that as a shift point until I got used to it too. It's not dramatic like forced induction but it is noticeable and I think it was worth it. Normally aspirated power isn't cheap on these motors so it's probably the best bang for the buck. FWIW, I recently had some unplanned head work done by VAC Motorsports which included the 'more aggressive' Stage 1 valve seat angle grind. They claim it improves airflow at lower RPMs resulting in more torque and HP. I had it at the track this past weekend and I think they are correct. i.e. that seemed to more than restore any lost power. It's an awfully expensive way to get that power back but if you're doing anything to the head it's worth keeping in mind. I've not had it on a dyno before or after any of this so it's all seat of the pants observations. marty Matt Bader wrote: > Date: Tue, 10 Jul 2007 12:11:02 -0400 > From: "Matt Bader" <mbader@exammaster.com> > Subject: RE: [E36M3] replacing intake manifold? > > Thanks, Marty.

Remember that, as for feel, when you loose low end torque, even if the top end power was unchanged, you'd notice the sudden increase in power up top because the difference between torque levels (low-> high rpm) would be more significant. You do gain some top level torque, but for anyone doing this mod, you have to ask yourself how important the top end power is. If you're tracking your car, it may be very important. IF you're just driving around town or on country roads spiritedly, I'm not sure I'd do this mod without cams/supporting software. ...and of course, YMMV :) -Ben On 7/10/07, marty <mfraiser@earthlink.net> wrote: > > Date: Tue, 10 Jul 2007 13:17:01 -0400 > From: marty <mfraiser@earthlink.net> > Subject: Re: [E36M3] replacing intake manifold? > > yes, i am happy with the results.
