Subject: Datsun Z Main Shaft for 5 speed

Hi Jack, Doc here. You will find the service file pertaining to this situation at your local Datsun/Nissan Dealer. The parts man can look it up to check the replacement parts required and the current pricing.
Item two: It is not advisable to try boring the L24 block to the
L28 size. I believe the cylinder walls get too thin for dependability. Start
with the 280 block and finding a good one rebuild one stock, or with oversize
pistons. The LD28 crankshaft stuff is more exotic and will work but many
$$$ are required with more parts to correctly perform this engine
build. My best suggestion is to count the cost, and contact Jim Bowen in the ZONC Club. He has one of
these things that I believe is happy with and he can fill you in on the
truth of the total package, and the approximate cost too.
I hope that you can find some light to your questions..........and Wisdom
too...........

Hi Doc,
I saw your article in the ZONC newsletter about the later style 5 speed
main shaft locknut w/ left-handed threads. Could you please tell me what
years 5 speeds have the updated main shaft? And if I get an earlier 5 speed
what does a replacement main shaft cost?
Also, I am thinking of upgrading my L24 w/ an L28 w/ fuel injection. Is
it more expensive to bore out my L24 to L28 dimensions or should I buy a
remanufactured L28 w/ fuel injection from Nissan? I also would like to add
an LD28 crankshaft for more torque.
Any help you can provide is greatly appreciated.
