Please enlighten me. Injection or carbs???

I have Dellorto's on my car now & have all the parts to convert to injection.

Car runs great w/ the carbs. Starts & idles fine, passes emmisions, no problems. Mileage isn't as good as it could be w/ injection.

My last car was a 74 1.8 w/ injection. Had a few problems w/ hot start & stall, Temp sensor, fuel pump, relay pack.

Which system gives you the most performance?

I had a carbed 1.7 in my 914 till a valve decided to snap off the stem. Then I got a used injected 2.0 Power is great, as well as drivability.

However, I have had to do a ton of work to get it going. Still working on it actually. Here's the pains of what all I had to do to convert.

New FI hoses

Fuel lines (hard and soft)

rebuild the relay board (so the fuel pump would run, it was jumpered off the coil for the carb setup, well 2 boards).

overhaul the wiring harness as it was old and brittle

new FI trigger points

rebush distributor, new vac advance

clean injectors (all stuck shut from varnish), replace 1

rebuild the aux air valve (the two I had both quit)

boil out the gas tank at a radiator shop, the return line was plugged and a 4 inch piece of hard jello (old gas) was in there as well as a ton of rust, sounded like a salt shaker when you shook it.

replace the fuel pump (twice, first used one failed)

Go through all the ground connections on the car - everywhere


So that was a few hundred bucks right there, on something that was basically "all there" but sat for a while. That also wasnt a weekend project, sure putting all the components on and new hoses was the easiest part - but getting it to run period was tough. Brad Anders came over and checked my MPS, ECU, fuel pressure and got it running. Later I had trouble with it dying all the time and it was rust in the fuel tank clogging filters and injector screens. have an ignition problem that is preventing me from passing emissions currently, along the way I had accidently hit the coil and it spun in the mount and grounded out on the engine tin. 4 ignition switches later, re-running a new black wire that melted up I finally found my stupid mistake.

I had been doing this a few hours a night whenever I had time and it really has taken a while to get things where they need to be. Now, if it is all good and one of the FI components fail in the future (MPS or whatever), big bux, big bux.

If your car passes AZ emissions now and is a pleasure cruiser as you say - leave it alone. If you have a part that fails for your carb setup it is a helluva lot more simle and cheap to repair. Also, you didnt say if you were doing the work yourself or farming it out. That could be quite an investment in itself.
