Im not 100% sure on the l16, I know this can be done on l18,l20 blocks. With l series a plug has to be inserted in block, very simple.

two main issues with ka24de head on l, or z series block

1. upper cover/lower timing chain covers have to be modified to fit together, this is really very simple considering the benefit of head swap. you will have to use the timing cover for the block and de upper cover.

2. lower timing gear issue. the ka24de/e use a lower gear with less teeth than the l, z series. You cannot swap them because the older engines use larger crank snout diameter. You can remedy this by getting your own custom gear made, modifying yours, or turning down the crank snout (which involves other necessary modifications).

the fwd and truck ka24de do not use a front cover mounted distibutor, these heads are the best candidates for the swap imho. you would run a crank driven distributor.

from what ive seen the z timing chain guides work better with the dohc setup, remember you will need a shorter timing chain if using anything other than a tall ht. block (z24,ka24)



edit. yes i mean z series engines z20, z22, z24. z cars use l series engines.

well i havent fired mine yet as it is long from finished, and i need invest another grand in it. I build nissan/toyota engines for a living, trust me it will run very well. I am not the first to do this type of swap.
