Fuel injection

[layne352003]

Anyone running a 79 fuel injected 1600 engine? Any problems from running that year engine?

I don't have any personal experience but I've had friends running late 70's Porsche motors with fuel injection and they say the systems can be tempromental. Was told they are susceptible to moisture and have issues if components get wet. I would imagine that would cross over to the VW side or more people would be doing it.

It's as reliable as any other system, it's just getting far harder to get parts. Done properly, it makes for a well running engine. A guy I know took a system from an early model Rabbit (CIS) and put it on his Beetle engine. I'll have to ask how he did that...

Later flat fours had EFI and didn't Mexican beetles have in the later days too. personally I would keep as many electrics AWAY from the engine as possible, all you like on NONE essential stuff though.
A pair of well tuned carbs any day, might get a couple of MPG less and very slightly higher emissions but a lot simpler and performance wise, not a lot in it, mother in law has an old Honda Civic 1.4GL with dual carbs and it goes like like stink.

I was thinking of staying away from the fuel injection system. Guess you all have helped me with my choice. Another question. been looking at the after market A/C units, Which VW engine would you put one on? I am figuring the larger the better but when will space to fit everything become a problem. Or just scratch the A/C idea altogether? thanks for the input.

Search the forum for a/c discussions. Lots of info.

Bigger is not better, you only have a two seat cramped cockpit, a small compact system is fine

By bigger i was refering to the engine displacement. The A/C unit will have to be as small as I can find.

Larger displacement engines will have nothing to do physically with the compressor, as it will only fit in one place. Personally, I wouldn't run anything smaller than a 1776 with a modern compressor - you will feel some power drop when it kicks in. It will be a trade-off: larger motors will handle the compressor better but they will also require somewhat more maintenance and tend to have shorter life spans. A compromise would be a 1.8 or 2.0 type 4 engine, something that already has more torque to begin with than a typical type 1.

Really?*nothing to see*

Something I don't know, Peter? Please, share! Compressor mounts for a typical type 1 engine are to the left of the generator stand, replacing the fuel pump. Physically speaking, that should have absolutely no effect whether it's a 1300cc or a 2180cc engine.
