I have a 1980 B210 four door. I also have a Z24 and a KA24E, trans from a 1985 720, two solex side draughts, plus many misc. brackets from the 720, 240 SX and my 210. It is mechanically stock now with the A14 and five speed. I need some defintive awnsers on the motor swap. Which motors mounts to use, and what to do about the crossmember/steering/oil pan. Do I cut up the oil pan, or cut up the crossmember? one of them has to move! I'm not scared of cutting it up (sawzall is my favorite tool).

I think the KA24 fits better.

Z24 is too long to do easily... as i remember.

Check the wiki, all the engine swaps are discussed a bit.

better get some 280zx struts for a conversion too, that's gonna be heavy for stock front end, and way too much power for the stock brakes.

I am actually using the Z24 bottom end with the KA head. Same basic engines. But I have searched all of the wiki swaps and still have some questions. I am wondering if there is a front sump pan for the Z24. Even a mid sump would help. Anyone know?

ok no help here but i think its funny how in other parts of the world, most people would love to have an a14 and 5spd in their 120y, i know i would.. good luck with it anyway

the Z18 had a front sump, so maybe thats the go - or a Z-NAPS, whatever one of those was, which i assume would have been a Z20. I would be using the KA24E, as it's a more refined engine, but i would be looking to add a T (turbo charge it) to that designation, just for that extra monster factor.

SO do you have a connection for SMOGs
or is vehicle going to be off road use only??

isnt it exempt because of the cars age? be over 30 years of age.

not anymore,
now its mandatory 1975 and older

there are other ways to deal with that ;)

basically if it came with any emissions equipment it has to stay at that level or better... However CA is somewhat inflexible re: better. You'll be arguing with the smog referee for a long time trying.

Truly, in CA you can't even change transmissions without it being emissions tampering.


Hey Leo long time no see!

The motor is going to be capable of running methanol by changing the jets and the fuel alone. It will have a catalytic converter so the cops can't say ####. There are many ways around smogs, legally. We just have to be smart about it. My motor will pass a smog, even with twin 40mm solex's.
These cars could be optiond with twin SU's, so whats the difference with running solex's? And the block of the motor is a Z24, so the numbers say it was origanally a carburated engine. It's the visual inspections that #### most car enthusiasts. Make them look factory!!!
