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

[Rowleym]

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.

+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.

Just break out the heat&hammer

Got this bad gurl detailed yesterday

Mats before and after

Some of my ignition coils must be cracked because the moisture from washing the bay caused a bad misfire. Hopefully I can find a coil today to solve that issue=)

A clean car that doesn't run is as bad as a dirty car that runs great

[Earl]

It runs and drives. It just misfires now. John is coming to save the day
