Rb26Dan240z Posted September 26, 2017 Share Posted September 26, 2017 (edited) Hey all, Long time lurker, first-time poster. I am currently in the process of building an early 240z with a rb26 in it. I have just finished rebuilding my motor and mating it to the rb25 gearbox so I am in the process of getting it all mounted up in place. I am using the CXracing mount kit. I would have gone the McKinney kit but unfortunately here in Australia the dollar was low at the time of ordering so this was the only affordable one. Anyway, I have got the engine mounted up and am having trouble getting the gearbox up in the tunnel as the speedo sensor is interfering with the ears. I'm not sure the best way to go about fixing this issue. I have seen plenty of pics of peoples mods of notching out the bracket with the other style of tunnel mounting but I can't see any solutions that utilise the cx mounts I have. Has anyone come across and solved this problem at all? I have uploaded 2 pics of the interference, and also one of the mounts that I have that attaches between the ears. I have already tried just moving the engine forwards but the mounts are already set such that the engine is as far forward as possible. Any help would be much appreciated!!

510sr20det Posted September 27, 2017 Share Posted September 27, 2017 they have to be cut out and have to run our 260z or 280z trans crossmember set-up.. Quote Link to comment Share on other sites More sharing options...
unterbergamotten3 Posted October 4, 2017 Share Posted October 4, 2017 What we did to make some clearance is to rotate the engine with an aluminum spacer on one of the motor mounts. plus grinding the tunnel mounts a bit back. Quote Link to comment Share on other sites More sharing options...
510sr20det Posted October 20, 2017 Share Posted October 20, 2017 the original (ears) trans mount must be cut out... on Late 1973 -1978 body.. that is why we use floor mount trans crossmember. Quote Link to comment Share on other sites More sharing options...
