Lets design an engine. have a bunch of d-series blocks laying around so I decided to throw one together just to mess around with and play with ignition timing. I want to do this as cheaply as possible since it will probably blow up. I'm setting a budget of $200 excluding gaskets and fluids. Here's what I have laying around.

z6 block
a6 block
z6 crank
y7 and y8 head
z6, y7, y8 rods and pistons
eagle rods
vitara pistons
garrett t25 turbo from an old Saab.

if you had $200 and these parts what would you build

 

z6 block, z6 crank, eagles and vitaras of course, y8 head and the turbo.

 

Agreed

 

Either what's already been suggested, or the z6 block and crank with the eagle rods and y8 pistons.
