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 914 fuel injection systems (either ljet which you've got, or djet) are extremely well-engineered. The Bosch engineers are some of the best in the world and I don't say that lightly. The people who advocate ditching the FI in favor of carbs do so only because they don't understand the FI system.
If in the future you decide to go for a high HP rebuild that exceeds the authority of the stock FI, then you should consider other options. But right now, keep the FI, take the top off, drive the car. |
