=O

Also, just checked the tracking number and the boot will actually be here today. :alright

Looking fresh Earl!!!

I replaced my intake boot yesterday.

There was pretty much a tear between every bellow. The throttle response didn't feel like it was lacking before but it is much more responsive now. I did notice that someone had split the end of the hose coming from the PCV valve and used electrical tape to fix it. I will most likely be replacing that next.

I was driving to work this morning with the blower motor on high to defrost my windshield and it suddenly kicked down a speed or two. I have heard horror stories of blower motor relays going bad and causing dash fires/full harness shorts in e34's and do not want to even turn the blower on now...

Just another reason why this damn weather needs to cooperate!!

This months heat bill was literally half of last month! I call that progress

[Earl]

I just noticed something.....do e34's use m42 radiators or is the radiator wider and has an integrated expansion tank just like an m42?

[B C]

probably the same expansion tank with a longer core

[Earl]

Hmm........

[Earl]

This thing has been awesome=) 

Tomorrow I am getting it detailed and I might shadowline the trim. 

I noticed a slight exhaust leak this morning that sounds like it is coming from around the downpipe. Are these cast exhaust manifolds known to crack? I remember on my Conquest those manifolds were prone to cracking, but that was a turbo application. 

I ran across these and am getting tempted. http://www.racelandus.com/exhaust-headers/bmw-exhaust-headers/bmw-e34-exhaust-headers.html

Someone talk me out of it=)

Not saying you shouldn't put headers on, but they aren't bolt on.  I have a set of cast manifolds you could have for cheap if you want to go that route, I don't think they are know to crack though, might just need a gasket.

[Earl]

I am confused by your statement Mister Menard

"The exhaust header will bolt to your existing factory exhaust or other aftermarket exhaust system for an OEM-like fitment."

I do own BFH's so I don't foresee any fitment issues.

Same as what our 11%-er said, I havent heard of the BMW cast manifolds being known to  crack.

I wouldn't run headers unless they were long-tube but that usually ends up being a PITA.

I guess I would run cheap shorty headers if it ended up being cheaper than a replacement cast manifold and you didnt mind possibly sacrificing some low end power.

[jc43089]

Looking at the pic on their site it appears that its more like a "slip on" to your cat section, it has its own downpipes which have a two bolt flange from header to DP rather than OEM 3 bolt.  Looks like you install then cut your cat section and clamp or weld the new downpipes on.  Not a bad setup, and I may go with this in the future, just not a direct bolt on.

[jc43089]

You can also get the m/s52 tubular header type manifolds for cheap, which are a direct bolt on to your downpipe and look much cooler, not sure if they flow better though.  This is what I am doing for now.

[wasnt m3]

+1 on the s52 manifolds.

[Earl]

Do you guys have a link to those?

[wasnt m3]

They are stock headers from 96-99 m3.

[Earl]

oh gotcha....hmm

[jc43089]

m52 and s52 headers are identical.
