I am on my last nerve trying to get my 74 1.8 ltr L Jetronic fuel injected car started. Bypassed the seatbelt interlock to get the starter to work. Hot wired the fuel pump to get it working and still no go.
I am considering a carburetor conversion and see that Redline has a few kits. The dual carbs system has no choke and the single carb with electric choke has some distance from the cylinder heads. Anyone have any success they could share? |

The stock FI parts are over priced and don't really offer any advantage over a properly tuned set of carbs.
The old "different cam" theory is long dead as the part number is the same for our US market FI cars and the carbed cars in the EU market. Yes you can make more power with a performance cam but that's true on FI also. If you do carbs purchase a new set of HPMX (no cold idle circuit to deal with) from Empi, open the up and inspect and clean them. Dorking around with antique used equipment is not worth it (especially ancient Italian Webers that weren't right from the factory). Get a syncronizer and a wideband O2, set aside a day to drive around and tune then and you'll be very happy. |

QUOTE That's why FI died some 40 years ago and nobody uses it anymore. Carbs rule today's automotive landscape for a reason! (IMG:style_emoticons/default/rolleyes.gif) You misunderstand the point. I don’t see anyone trying to make an argument that carbs are better than FI. Bosch were ahead of their time with the systems they made for the 914 and FI is superior to carbs. The point is 50 year old FI will never be as reliable as a brand new set of quality carbs and a new pointless distributor. |

The L-Jet system was used on more than just the 914 and the system is well understood and parts are readily available. When i still had my 1.7L D-Jet i went through several months of trouble shooting and eventually merged 3 engine wiring harnesses into one good one and got the engine running as smooth as the day it came off the assembly line. I've also had a warmed over 2056 with dual carbs and an aggressive cam. It had loads of power the few times it actually ran ok, but in terms of smoothness and reliability there just is no comparison. FI all the way. Just try to start a carbed car jetted for sea level at 5000 feet up in the mountains and report back to me how much better than FI they are. (IMG:style_emoticons/default/shades.gif) |
