Fuel/air choices...

Okay, so it's come to the point where I want to decide if I'm going with FI or carb. I have narrowed it down to a complete 320 EFI transplant, or dual sidedraft Webers. Now, around here, the junkyards have shit for BMWs, so I'd be stuck buying the setup from someone, which would be hard to find and expensive? Also, is it difficult to install?

On the other hand, as this is as more of a fun car than a daily (though I want it to be reliable), the dual sidedrafts would be damn cool.

Help!

A very simple injection set-up would be the 318i L-Jetronic. It is much easier to install and tune...

But for all out HP, nothing beats Webers, short of programable injection...

Especially if you want to be reliable, L-Jet is ok but only for very low boost which isn't much fun. L-Jet would be easier to upgrade to programmable later though, but K-jet is cheap and simple to setup for boost.

but adapting for performance when using it on a 2 liter engine is very difficult.

Use L-Jet manifold, fuel rail and fuel pump from an E30 318. Add a bigger throttle body, different injectors and a MegaSquirt brain and you have a completely programmable system that will flow more air (=more HP) that you can _properly_ tune to deliver performance and driveability. Big bonus, you can do the whole bit for <$350 (with EFI brain).

Cheers!

this before and has a bunch of jets in stock. that way you are paying for labor and not parts. Might turn out cheaper, but you'll have to find people that know what they are doing.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
