Wizeguy9999 Posted February 24, 2014 Report Share Posted February 24, 2014 Hi: I'm building a 68 Datsun 510, and had a question. The L-series that I'm putting in is well above the 90HP of the original L16. I was curious if this would require better motor mounts than OEM equivalents. If so, does anyone know where you can buy beefier L series motor mounts? Thanks for the help! Quote Link to comment
ggzilla Posted February 24, 2014 Report Share Posted February 24, 2014 The stock mounts are fine. They aren't designed for HP rating, but for durability. Newer ones are softer and technically handle less torque, though after market ones are all the same. Quote Link to comment
Wizeguy9999 Posted February 24, 2014 Author Report Share Posted February 24, 2014 Would an increase in weight matter then? A 1.6 liter versus a 2+ liter engine? Here is what I'm looking at: (http://www.carparts.com/details/Nissan/510/Beck_Arnley/Motor_and_Transmission_Mount/1969/Base/4_Cyl_1-dot-6L/104-0827.html) What generally concerns me (and maybe it shouldn't, and I should be happy and move on) is that these are so inexpensive versus upgraded motor mounts for installing like a KA (those seem to run like $100+). It just seems odd that the motor mounts could be basically the same but the cost be so different. Quote Link to comment
ggzilla Posted February 24, 2014 Report Share Posted February 24, 2014 The L16 mounts work fine with a KA24 Quote Link to comment
datzenmike Posted February 24, 2014 Report Share Posted February 24, 2014 L16 255 pounds L18 260 pounds L20B 275 pounds Taller block, larger full counter weighted crank, longer rods Motor mounts are not an issue. Quote Link to comment
