Spider engine swap?

[ajnsbdfr]

I have a 1977 Fiat Spider 1.8 and would like to know if I should swap my 1.8 to a 2.0. I am going to rebuild my engine and would like to know with engine would be best. Also any sugestions on with heads to use on the engine for best performance.

If it is a minor rebuild and you have a 2.0 block, then yes put your 1.8 head onto that. It will give you a little bump in compression, but not a ton just somewhere between .2:1 - .5:1 depending on machine work. But, if you don't have a free/cheap 2.0 block then just stick to you 1.8 system. I've driven a 1.8 with the 2.0 fuel injection on it, and wow what an amazing difference. The revviness of the 1.8 over the 2.0 makes it REALLY accelerate fast with fuel injection.
