D_vision Posted August 29, 2008 Report Share Posted August 29, 2008 i got a 85 720 5-speed with a z24s w/dual webber sidedrafts and two fatty accel coil's, and a header, a 79 510 4-speed with l20b stock, a 78 b210 auto trans. with a14 stock, and a 71 521 with l16 4-speed w/ header and 2 barrel webber....so of course i have ideas for all the body's but specifically the 210 is the baby i have been reading a lot of forums and tryin to figure out what to do with all of my power trains my main question is do i do a straight motor swap or do i creat one of these l/z24 hybrid's everyone's talkin about then i read somone was taking l16 heads and putting them on l20's for what? kinda a broad question i think but hopefully somone know's alot more than me here thanks Quote Link to comment

CharlieBucket Posted August 29, 2008 Report Share Posted August 29, 2008 i have a 77 b210 5 speed and i have have a really hard time finding any siddraughts or upgrade parts for the a14 in general. so i say either swap out the motor or just use it for the great fual economy it gets. i think a ka is in the future for mine or just a l20b would probelly move it along nicely. for now thou i am just cruisin mine stock and trying to make it look good. i don't know anyting about z/L hybrid motors. let me know if you find a good source for a14 parts. i'd like to push some power thou the stock motor if i could. got any pictures?

Good performance but not that much room for more. You would need to make motor and tranny mounts and shorten the drive shaft. Heavy motor so better front springs, brake up grade is a given with this motor. L20B ('79 510) good second choice. Still need the mods above. Lighter motor than the Z24 and more performance potential, but keep in mind that you'll have to do a lot just to get even with the Z24. Big detraction is the 4spd, a 5spd would be better. L16 ('71 521) an improvement over the A14 but for all the work, one of the above would be better unless you are wanting economy. Like the L20B there are lots of performance parts and potential. Throw this 4spd away and use the one from the '79 510, 5spd would be better. If you had a Z22 I'd say go for the LZ22 conversion... the Z24 is much more complex. Motor swap is enough for a tiny B-210 anyway. The stock L16 head has no advantage on an L20B. They have small ports and valves, 'smaller' cam and the head chamber is smaller so too high a compression on an L20B engine. I suppose if you could find a 219 SSS head casting there would be some improvement, but you could just port the L20B head to the 219 size and have basically the same head and cam.

D_vision Posted August 29, 2008 Author Report Share Posted August 29, 2008 thanks fro the info i think i will get a header for the l20 and a intake manafold for the dual side draft webbers do you think it would be possible to mate that 5-speed from the 720 to the l20b then i could use the 720 rear end as well Quote Link to comment
philip1 Posted August 29, 2008 Report Share Posted August 29, 2008 the 80 b210 can use the pl510 cross member. You will have to make a custom trans crossmember and use a stock 210 auto driveshaft with the Z-5speed Quote Link to comment
datzenmike Posted August 30, 2008 Report Share Posted August 30, 2008 thanks fro the info i think i will get a header for the l20 and a intake manafold for the dual side draft webbers do you think it would be possible to mate that 5-speed from the 720 to the l20b then i could use the 720 rear end as well Check this out. He says he has an L20B in a '76 B-2110! http://forum.ratsun.net/showthread.php?t=6088 The tranny will bolt up but two things... 1/ the '85 720 uses a NAPS Z series motor which sits in a more vertical position than the L series by about 12 degrees. If you mate it to an L20B the shifter will be leaning toward the passenger seat. I guess you could put a bend in the shifter. The tranny mount surface would also be tilted, but you would have to make up something for it anyway. 2/ the '79 HLa10 uses a short tail 4 speed so you would have to shorten the drive shaft for the longer 5spd. Do-able. Quote Link to comment
philip1 Posted August 30, 2008 Report Share Posted August 30, 2008 I have and I can give any advice you need I'd be glad to help any way I can BTW here are a few photos of the engine just after startup. Quote Link to comment
D_vision Posted August 30, 2008 Author Report Share Posted August 30, 2008 ok so i have pretty much decided to go with the l20 with the dual webber side drafts get a header and do some real nice ignition mated to the 720 5-speed i will use the 720 rear end get some posi gears and use the 510 4-link set up on the rear i was looking at the 210 and the 510 look like the same chassis almost so could i technically take the cross meber from my 510 and bolt on conversion and same for 4-link i know its leafs on the 78 but i think the 4- link will mate up nicely with some cutting and welding .......the reason i am leaning on the l20 is the upgrade possibilitys i eventually want to do some scca course racing and i know that little 210 would turn some heads:D Quote Link to comment
philip1 Posted August 30, 2008 Report Share Posted August 30, 2008 the leaf setup is more than strong enough for even a strong L20 I even used the original b210 diff Quote Link to comment

This is more than you will ever need. Don't waste your money upgrading this... spend it on suspension or brakes! The '79 has a solid H-165 axle. The 720 (assume a 2wd) has an H-190-ML solid axle. Not even close. Forget swapping the whole thing the 720 axle is H E L L A W I D E. If the PL 510 wagon is the same width as the HL maybe go with it. Its a solid axle with leaf springs, may bolt right on to the '79, and has an H-190 gear. You would then be able to swap in any 620-720 truck gears ranging from 4.11 to 4.88. Quote Link to comment
Guest jaimesix Posted August 30, 2008 Report Share Posted August 30, 2008 I have and I can give any advice you need I'd be glad to help any way I can BTW here are a few photos of the engine just after startup. Nice air box for the S/Us. William, take note. William is using S/Us in his 4 door sedan 610. Interesting to learn the 510 crossmember will work for a L series swap onto a B210. I knew 610 crossmebers worked, since the front susp of the 510 and 610 and 710 are similar ( only diff is the sway bar center brackets ), makes sense.

CharlieBucket Posted August 30, 2008 Report Share Posted August 30, 2008 so i think i am convinced. so let me see if i got it straight. i need a l20b, a Z 5-speed, b210 auto driveshaft and a pl510 {whick means any 68-73 right?} crossmember. then all i need is motor mounts and a custom trans member? that really cuts down on fabricating. would a dogleg tranny work? like a 200sx one? of just the z? also would the trans tunnel work and the stick come though the same part? i bet with this and just a regular weber would move the b210 pretty good. su 's can wait.

Guest jaimesix Posted August 30, 2008 Report Share Posted August 30, 2008 The Dogleg will work as fine as the regular 5 speed. The cross member could be a Datsun 510, a Datsun 610 or a Datsun 710, as well as a Datsun PL510 ( Stanza overseas ). Perhaps the Datsun 200SX S10 crossmember would work as well, got to find out about that one. It has an L series engine, but the frame dimensions could be different.:confused: You can use 280ZX struts at the same time. The 280ZX struts work on a B210 fine. You can always modify your A series as well, depends on what you are looking for. Jaime.____________________________________________________ Quote Link to comment
