Duel carbs VS. Fuel injection, Whats the real deal Options

[Jaymann]

So whats the real story.What are the pro's and con's,I am working on a 1975 porsche 914 1.8L 4cyl. I am currentley using the stock fuel injection.I decided to start this project, by getting the car running back to stock.This car had been in storage since 1992.The gas tank was bone dry, and in perfect shape inside and out.I replaced all the fuel lines,filter,fuel pump.All the vacuum hoses,a bunch of gaskets and o-rings and stuff,chaged the oil,fiters etc,and did a complete tune up.
Now she runs ,and starts real nice.The car has very little rust at all anywhere,the motor runs very strong.This car has always been stored in a heated garage,and never driven in bad weather.My end goal is to have a car that is still street legal,but I can run at the track.So if I rebuild my motor and go from 76 h.p. to like 150 or 185hp can you still use the f.i. or do you need duel cabs at this point?I am not a mechanic, and this is my first 914.So please forgive me, if I ask any stupid questions.I am planning to run this engine for a while,she still has plenty of life left in her.I am just trying to figure out, what I want to do in the future.Jaymann

The L-jet systems is capable of high horsepower, but you can't use a radical cam with it. The air flap starts to flutter at idle if you do, and that really screws things up.

But you won't get there with a stock 914 intake system, the throttle body on a 1.8L is way to small for any serious performance improvement. If you want to do anything with the injection, then you have to bore the throttle body.


The rest of the system is seriously reliable when treated right. I suggest you drive your car the way it is, and plan a new motor if you want more ponies... That way you can keep driving it,and build the new motor over time.
