Need help again. I found out my car was originally from California. Any indication of smog equipment is gone. So how is the smog pump mounted to front of the engine? I've seen the parts and would like to see an engine with this installed.
Thanks, DaveB |

neat set of docs @914Mels
@DaveB attached docs @JeffBowlsby pointed us 74-1.8 owners at last year when he alerted us there was a 49 states and a cal version of the 1.8 in 74, despite other accounts saying it was a 50 state engine. bit more difference in 75. these docs outline it. ![]() ![]() ![]() jeff has the whole document (75 training manual) on his website if you want to look it right through. interesting idea putting the emissions equipment back on. as far as i can tell the equipment on a 1.8 had no negative impact on horsepower. the 1.8s suffered from reduced horsepower due to low compression for unleaded fuel, but the emissions equipment itself produced no losses. at least at that point in time. the L jet electronic fuel injection helped these little motors cope. possibly some impacts on driveability and throttle response. and like all 1.8s 74 and 75 running hot at idle due to ignition retard from vac chamber on distributor to lower NOx (remembering the 2 way cat does nothing for NOx so they were doing it by running lean and retarded at idle/or cruise). ------ it looks from the info that jeff had that it was only the 75 49 state 2.0 that had a smog pump. and CAL 75 2.0 had EGR and CAT but no smog pump. ------- thinking a bit more about your cat location question. the 914 has a short exhaust system. don't think the cat was bothered by trouble heating up or having a correctly hot exhaust system like conventional cars with much longer exhausts where it makes sense to get them up nearer to the engine. |
