Question moderate changes to a 1.8

In another post, I saw mention of making a 1.8 into a 1911 using flat-top 96mm piston/cyl asms. Can you retain the L-Jet with this change? Any need to bump the richness by faking the ECU or using 2.0l Bus injectors? This isn't that much smaller than the original 2.0; does anyone know how close it gets to the 100hp of the higher compression 2-liter engine?

I ran this combo and I never had any problems. The car ran great.

No need to worry.

Any idea what kind of power does it make over the stock (76hp) 1.8? Does it approach the performance of a stock 2.0?

I saw a while back Rolando Cruz referred to a European spec 1.8L with carbs that developed 85+ HP. It was his favorite engine of the 4 cylinders. Anyone know the details on that? Was it standard issue overseas? What's different? The cam I assume?

I like my '75 FI, but I also had a '74 1.8L with carbs that when tuned right really ran very strong. It was a PITA to keep tuned though.

From what I think I remember reading - the "Euro" 1.8 was fitted with dual single barrel downdrafts and had a compression ration of 8.?:1. I don't remember if they were Solex or Webers. CB Performance has the setup (and probably others).

Don't know anything about the cam.

Will,

This combo should yield around 90hp with some mild clean up on the exhaust ports.

The 1.8 had a breathing problem.

Put 2.0 heads on your 1.8 and watch it come alive.

The spark plug angle really really helps the 2.0 heads.

8.6:1 compression, engine code "AN". Also used on some of the 411 or 412 cars. Dual single-throat 40mm Solexes (40 PDSIT, I think). The factory parts book calls it the "1.8V". Made 85 HP, DIN spec.
