Bmw e30 m30 exhaust manifold??

[bimmer1987]

Hi all
I am coming to the end of my e30 m30 conversion, and i have just the last two things on my list...the prop i have under control but the manifold on the other hand is another story...

My Engine was out of a e32 735, the exhaust manifold closest to the bulkhead clears the steering knuckle but the one closest to front of the engine doesnt..any help would be great...
Cheers jay

I removed it cut the exhaust flange off the end and turned it 90 degrees and welded it back on.
Careful not to sheer an exhaust manifold stud like I did

It should clear without modding, what steering rack you using?

[johnl320]

I think there are differences between manifold of e32 and e34, mine is from an e32 and deffo needed modding

I know theres a manifold and it looks like a long log style but i thought these were on earlier donks?

[bimmer1987]

Im using the standard steering rack...i lined up the left hand mani and i know i can work with that but the right one..im sure when i lined it up it sat directly facing that knuckle...the cut and bend 90 sounds like an idea...

I had to cut turn and shut mine too.

I didn't cut or shut mine, I was liucky enough to heat up the flange and turn it 90 degrees

Jay,

My E32 rear manifold had to be cut and shut to fit. I eventually replaced it with a full stainless BTB system, so I could possibly be tempted to let the full E30-M30 Powerflow system go if you fancied an easy route.

It would need to be worth something though, else I'll just keep it in the garage as a backup in case I ever sell the BTB.

Pics below (system nearest the fence) that may help show the manifold.
