Im wondering if the exhaust ports on the m103 match up with the ports on the m603? See where Im going with this?

No? Ok well I have both motors and id really like to turbo my 103 with the parts from the 603. My weak knowledge of the two motors says the ports should line up. Both L6. Both 15 degree. Both sit in the same body with a 2 year difference in production.

If this rings true, i may be able to turn my dirt cheap(600$) w126 into the screaming white highway cruse missle it so deserveingly wants to be!

Any help or info would awesome!

So whats the best way, other than an engine swap, to get this poopy motor to fly?

Also I have the 1991 350sdl, that was where I was going to pull from. Also swaping the larger radiator and AUX fans from the front clip. Again Just from looking they seems to be interchangable.

 

Also Ive seen coil over conversion kits from H&R. Wondered if anyone had experience with them?

 

Well the parts were there. The true owner, my pops, has forbid me to mangle his car just to kill myself in mine. His words. Now I need the manifold from somewhere. Any idea where i might find one?
