75 agave 02 M20 swap


Recommended Posts

I wanted to share my project that i have been working on for the past 10 months. To start it off i bought the car about a year and a half ago. The car had around 160k on it came with the stock m10 and 4spd trans. I drove the car for about 6 months and loved it but it just needed a little more power for me. I did a lot of research on the m20 swap and i have owned other e30's before so i knew it was the swap for me.

Here are some pictures before the swap.(first time posting pictures so forgive me if i mess up)





Heres some pics of the motor and trans (M20b25 and g260 trans)



Took out the old motor and transmission rust everywhere looks to be mostly from leaking fluids.



So after getting everything out of the engine bay i decided it was time to cut part of the front end and make some room so i can get the new motor in and start measuring and making adjustments.


motor just hanging from hoist.


I will post some more pics soon as i get them uploaded to my computer.

Sweet! I was waiting eagerly for you to upload some pictures of your car and everything. Your old 4 speed is still humming along sweetly in my 02.

Looks like you've made a lot of progress since I last saw your car. You gonna put the front bumper back on?

I am strongly considering the same swap for my project.

When you cut out the front for engine acces... is that required for the engine iteslf, or mostly a radiator thing?

Hey Im glad to hear that the transmission is holding up for you, it never gave me problems. I still have that motor if you or know anybody that is looking for one. I Have a bunch of parts left over and will be posting them up here soon. I probably will put the front bumper on for a while till i figure out what im gonna do in the front end. We need to meet up soon i would love to check out your 02. Im working on the exhaust now so i should be able to drive around soon.

I just cut it mostly to make room for the radiator, and to make things easier

im sure you could do it without cutting it all out.

looks like you ran the fuel lines up the passenger side and into the engine compt over the exhaust? not really a good path. too much exhaust heat near the fuel. should run them over the diff and up the driver side.

just a thought.

I thought about running it the other way gonna keep an eye on it. I might have to change it.

Im going to agree with marshal on that one.. even if the fuel doesnt catch on fire from being closer to the heat (and it probabaly wont unless there is a leak), the fuel will still be heating up inside the line, which can cause efficiency issues once it get into the combustion chamber, thus causing the engine to have less power (if it heats up enough). The cooler the fuel is the better.

I haven't been on this site in a while the 02 has been coming togeather slowly. I haven't had too much time to work on it, I've have been focused on selling various BMW parts on eBay to fund my project and working on other projects like my brothers 89 E30 s52 swap. Its coming time to finish the 02, But i have to say its fun learning all these vintage Bmw's. The pics i have posted are old and there are updated pics coming soon. When ever i work on the 02 is free time and I'm sure like a lot of you its hard to come by. Here is a pic of my brothers s52 :)))))

    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
