manual conversion

[karlos]

hey there I've done a manual conversion on my skyline and am wanting to confirm if i need drive shaft hoops or not? also i could only get two bolts into my gearbox crossmember out of the four, have you any idea what others have done to pass cert with these cross members?

Hi Karlos,

Your Skyline will need drive shaft loop if

(i) the vehicle has had an engine conversion that has resulted in a significant increase in
power or torque; or
(ii) the vehicle has had its factory‐fitted engine significantly modified, such that a significant
increase in power or torque has resulted; or
(iii) the drive‐shaft fitted to the vehicle has been modified by welding.

Regarding the cross member bolts, the mounting attachments must match, or exceed that of the original manufacturer's method. Therefore other such vehicles certified will have either used a different crossmember (to allow four bolts to be used), or new attachment points have been fabricated to allow four bolts to be used. Please contact your certifier (or other Skyline owners) who may be able to advise you on what solution other conversions have required.
