I'm piecing together a 3.1 street motor for my E30 daily, and I'm having trouble finding M20 headers I consider worth spending money on. The combination will be 1mm over bore, M54B30 crank, moderate cam, mild ported head, MSPNP, likely ITBs eventually.
Has anybody used the Becker headers available on Ebay? The rest of the ebay E30 headers tend to be a mess, but these ones are 4 times the price, so they're 4 times as good right? Seriously, though, has anybody used them? Do they actually fit?
I'm hesitant to buy the IE long tubes being as they're mild steel with pressed connectors, will require an O2 bung welded in the exhaust or a collector, will either vbands or flanges welded in (or using band clamps over a coating, which kind of sucks over time)... If they were stainless, I would just buy them, but having to either use band clamps and move the O2 sensor down stream, or having to modify them, and then send them out again for coating kind of turns me off.
Supersprints are still available, but they're obscenely expensive. Same with the Racing Dynamics group buy, (plus I would either have to use the small OEM down pipes, or build something myself) (not that big of a deal, but for that kind of money...)
Am I missing any other options? I guess I could do the IE shorty headers. I'm hesitant to buy a short tube header if there are better options. I'd buy Stahls or similar if somebody had a nice used set, but I can't tell you the last time I saw any for sale.
