95bmwm3 Posted June 3, 2005 Share #1 Posted June 3, 2005 Hello, first I know...I know this is a Datsun forum so ignore my BMW name : )I cut my teeth in the machine shop on Datsuns in the late 80's and early 90's so I have some exp. with Z's and Dimes but its been a while now so I have a few questions for all you experts.I have had the urge to build a 71 Z with a L20B for a nice little daily driver. Trust me I have had my share of Horsepower and Handling so now I just want classic looks and efficiency. So please don’t flame me with the "Why not a FJ or SR or....?" reply's : )So to the question has anyone done this swap or knows of someone with good documentation on this. Or possibly a kit for this swap, any help would be appreciated.Also does anyone remember where the SU carb came from in the old draw through turbo kits (KKK)? I was thinking of fabricating a tubular intake using a single large SU or a TB injector set up? I know kind of odd but I loved the look of "Coiled snakes" on my old draw through turbo Z from college : )Thanks for your time.

VaGuS510 Posted June 4, 2005 Share #2 Posted June 4, 2005 might be easier and just as economical to find an L20A, the 2 liter 6 cylinder that came in japanese z-cars. This way it is a much easier swap and I am sure would make a great reliable daily driver.

95bmwm3 Posted June 4, 2005 Author Share #3 Posted June 4, 2005 I had thought about that but from what I have been told is that there is not much difference between the two in mpg?Besides I realy like the look of all that extra space with the motor sitting back in the compartment plus the less weight and parts thing : )I wonder if anyone out there would trade a good complete L20B for a stock L24/L28 that seem to be in most cars I am looking at now?But thanks for the input.

Murph Posted June 5, 2005 Share #4 Posted June 5, 2005 I have a good complete L20B and could use an L28. Now you have to come to australia to do the swap. Interesting idea though. I'd be tempted to go the L20A idea though. I don't know that the work required to get the L20B in there would be worth it. Let us know what you end up doing!
