Need To Make up my mind , Need Your Help.

I really need some ideas. Wife wants me to clean up, so i need to do what i need to do and then sell all leftover parts. Here is what i have

entire 1984 318i.
Engine M10 with 220,000km
automatic.
great body, all new suspension, H&R, Billy's
Parts ready for the engine:
Dinan turbo manifold
ihi turbo x 2
intercooler
injectors
2nd m10 if needed
misc replacement parts.

entire 1989 325i
engine M20B25 with 300,000km
5 speed tranny
body /frame rotted
low compression on cylinder #5 (would need to drive it like it is , as i cant afford to fix it now)
engine sounds good , even with bad cylinder, drives smooth

If you had these 2 cars what would you do?

Do you always listen to your wife?

I do have to much sitting around. The body and frame on the 325i are crap so they can go, just need to know what to keep, and what to use for the 318i. Whether to put the m20 engine and tranny into it or leave the m10.

How much could i sell a m20 with its low compression along with the 5 speed for anyways? If i go that route, maybe i could do some work on the m10. Maybe buy a 5 speed?
i would also strip the 325i of all parts that i can swap to my 318i, rear discs, plastic bumpers, not sure what else. Anyone seen any threads that list what parts can come off of the 325i and go onto my 318i.
Was also wondering, i dont know what differentials both the cars have , i think the 325i may be a 3;73? since it is newer and in better shape, would i be able to put it onto my 318i? (new to this, might be a very stupid question.) if so how would that affect driving eg. make it slower or faster?
