Subject:This may sound stupid, but... can a 1.9 be set up as a 2.1?

After buying a house and all that entails (20% down to
avoid PMI, $$$, remodeling, $$$, furnishing, $$$,
fixing problems not reported on the inspection, $$$)
I'm ready to get my '87 back on the road.

My 2.1 dropped a valve some time back, and the
original plan was to replace the right head IF there
was no damage to the piston. However, I think the
damage is deeper-- I hear a deep clunking noise when I
turn the motor over, and I'm not about to try
replacing heads when 1. it's easier to pull the engine
and 2. I'm 75% certain that I'll end up pulling it
anyway due to a bad rod bearing.

I thought about a Nissan conversion, but that cost way
too much, as did a Boston Bob WBX rebuild (although
that might happen a year or two down the road
regardless). Everyone wants to swap a 2.1 into their
'83-'85s, making them scarce and expensive.

This is why I'm thinking of the opposite. 1.9s are
easier to come by and cheaper, and I understand that
the piston pins and crankshafts are better quality
anyway. I had an '84 before and power was never a big
problem, and the engine never gave me any trouble.

So, in light of the fact that a 2.1 can be set up as a
1.9, can a 1.9 be set up as a 2.1? Are there any
problems hooking it up to the tranny? How would the
oil pressure sensor situation be dealt with?

Any input is appreciated.

Thanks,
Sam
