how many of you were able to slap in new cams (bc, jwt, tomei, cosworth, etc) and not have to adjust the valves? this seems to be a timely and ghey job if anything is past its limit. btw, i'm planning on running BC stage2 cams with the springs and retainers, just tryna see who else has had to make adjustments after a cam swap. thankee

 

i think you would have to take the z to a nissan dealership to do the adjustment. Due to that they use buckets shims and replacing the springs and retainers would change the clearance?

 

Bucket shims are easy to get a hold of.

 

not a prob since i work at the dealer. im obv gonna be checking the valve lash but was curious as to how many people actually HAD to shim/replace the buckets. and i just ordered the cams/springs/retainers so.....

 

I'm in the process of doing it now. You install the cam, assemble it all The way up to timing chain installation, take your measurments, disassemble, install whatever thickness followers needed then reinstall. I always measure again just to make double sure I got it right

 

i'll measure them out with the heads OFF the block. easier to do each cam by itself and check it rather than having to turn the whole motor over to each line on the pulley to only do a few valves at a time. whichever way works tho
