M30 Headers FYI

[Bearmw]

I understand Ireland Engineering made some custom shorty headers for the E30/M30 swap. They don't advertise them but may have some sets left.

...can we get more info on this? Are they tubular? Do they suck like their M20 shorties? 2 or 3-bolt flanges? Do they match up to the M20 exhaust? Which swap mounts do they clear?

^ what he said

[Bearmw]

Yeah they are tubular 2" at the collector end with a 3 hole flange. I talked to Paul Burke (often on My E28) who is an M30 guru and he said they (or any tubular header) are much better than the factory cast manifold especially when combined with head work/cam etc and a 2!/2" exhaust. I'm not sure on the gauge steel and so on but they seem like a good option. I'd check with IE for more details on them.

did any info on this materialize ?

I contacted someone named alpinass on mye28 a while ago about the headers he makes, and he replied:

I have had this question posed to me several times...I believe with a little tweeking they would fit. I would purchase the 1 1/2" (painted). I will ask a performance shop that has stuffed an S14 and M30 into E30.

I never pursued it, but if you're looking for headers you may try asking him.

What's the going price for these puppies?

[chadthestampede]

~450 iirc

With a m30b35 in an e30 the paul ladue ( who is alpinass on mye28 ) headers will not fit without heavy modification. I found this out the hard way and basically had to completely rework them.

any shorty headers are going to be pretty worthless, although they may be better than the stock manifolds, only because manifolds in general are not great for performance.

a motor like the M30 probably wants headers that are at least 26-30" long, the primaries on most shorty headers are 12" or so...

[chadthestampede]

Someone needs to buy the bavauto long tube headers to see if they fit - most likely not.

[browntown]

Screw it, I'll just get the b35 stock manifolds coated so they look decent, and bolt em up.

someone needs to buy this and duplicate it...

Sure shortys are not ideal for this swap but I talked about it with Paul Burke and for those of you who don't know who he is I suggest you do. I told him I was going to port the stock manifolds and he said don't waste your time and suggested any headers. Until someone makes a good affordable longer length header for this swap I'll go with IE's and ceramic coat them Plus they are about 7lbs. lighter than stock.

Maybe someone with a shop on the east coast? :)

Seriously, it would be great if someone could come up with a copy of the Alpina header (oops, sorry, a header inspired by the Alpina piece}. The E28/E34 headers don't fit by all accounts, and short or not headers are better than the stock manifolds. There's a discussion at mye28 and in that is a link to another set of Alpinas that sold for 655 euros.

I would be in for a decently priced (realistically, under 700 dollars) set of bolt on headers. I too, know of the mystical Mr. Burke...
