[e//S2] is it possible to weld cast aluminum to extruded??

[Miller, Chris]

I'd look at the current setup first.  Are the runners all equal length and size?  They're probably optimized to allow equal air flow to each cylinder; moving the intake port to the opposite side may mess that up, unless you do some porting.  Might be significant, might not... might have more effect off boost, might not...

People want outrageous sums for these simple hunks of metal - whether its 3b or MTM - and it's pissing me off.  I'll be dammed if I'm gonna pay $300-$700 for a damned aluminum doorstop.

Ben:

Isn't the Dahlback IM a blend of cast and extruded?

even if it isnt, Jim Green and Javad Shadzi have welded up there own EMs...Martin Pajak has done cad drawings on the same.

I see NO reason at all why someone with a TIG gun cant put this together....even a MIG or Stick welder would allow you to tack something together and then bring it to a pro ....
