im starting to think i should do a 120y!
have to be 2dr sedan for sex factor though!

do you think the rack and pinion could be done easy enough or would that be a huge conversion, if using 910 crossmember?

also with the fourlink H165, you say it can be bolted in easy, is that using the fourlink suspension or bolting onto leafs?

have you considered using a h-190 diff naukkis, also with the h-165 you have is it a short one from a 1200 ute or something, or is it wider and you are using fwd rims or flares, if you used a h-190 diff it would require either flares or fwd offset rims on the back but it should be stronger than h-165 and all the ratios are still available, a h-190 is 90mm wider than a h145

Hey Rallycar, you can probably find all the answers to your 120Y/B210 questions at the Datsun 210 Club.

Is the B210/120Y crossmember the same as the B110/1200 crossmember?

yeah, I can't understand why more poeple don't do this swap.

I don't know about the H165 or H190 diff swap, but I have a cheap, easy option for you to think about.

The Aussie built 120Y's had a large locally produced BorgWarner diff instead of the tiny jap diff. These had a standard ratio of 3.89 and is strong enough for worked L series motors. As with anything though, you will break them if you abuse them constantly.

Many other locally assembled jap cars had the same diff, including some with much bigger engines. the KE25/KE30 Corollas auto versions have either 4.1 or 4.3 depending on the model. (there's a tin tag on the rear cover with the ratio stamped on it). There are slight differences in the pinion mountings though (crushable sleeve or shimmed sleeve) so you can't simply swap the centres without some messing around. You can use the entire diff (drum to drum) but it is slightly wider - I can't remember exactly but about it's either 2 or 3 inches overall. Not too much of a problem with the huge wheelarches on the 120Y - well on the coupe anyway, that's the only one I've had a close look at. It will pretty much restore the front to rear track as well with the Stanza struts. You should be able to use 6" rwd offset rims with only lipped gaurds. The mounts on that diff are slightly wider than the 120Y/1200 but only a matter of mm's and it will fit on the leaves no problem. There are 2 types of drum brakes on the Corolla as well, the one to go for is the larger unit, as the smaller type have that horrible sliding piston setup. The larger brakes use the same wheel cyl as the 120Y borgwarner diff, but will improve the brake bias (if you use the Stanza front discs) as they are more efficient.

I use lockers and I've only broken 1 centre and 1 axle so far in 5 years, and that was back when I still used to drive it on the street everday - not recommended!

Hi L18_B110, if that Corolla rear fits the 120Y, it should fit the 1200. Wouldn't front-wheel drive offset wheels tuck in nice under the back? The "310" fwd wheels fit on the back of the 1200 stock , but sit inside too far.

yeah, the Corolla diffs do fit the 1200. I doubt you'll get the same diff over there though. The one I mention is used only on Australian assembled cars. I use one in my coupe. you're right, fwd offset would sit pretty nice on a 1200 with that diff. It gives pretty similar offset requirements as Stanza struts do on the front. I just pumped my rear gaurds a little because I wanted to keep using my rwd wheels.

forgot to mention, you need to change the yoke on the Corrolla diff to the 120Y one, and use the 120Y tailshaft.

cool, i have seen these borg warner diffs but didnt know if they were stronger and what ratios were out there, thanks again

didnt know there was a 210 club, thanks for that, not as organised as this site but effective i guess, ill have a better look later

I'll try H190 when I get one to my hands. Now I use H165 from model 710 160J, it's few inches wider than stock H145. but it's just good as that stock axle is way too narrow.

No I mean that B310 has four-link H145 as standard and it can be swapped straight to four-link H165. With B210 four link needs custom made mountings and it's quite big job to do, I'll considering to make just Shelby rods to prevent wishbones benting. Those Shelby rods are just rods from spring front mounting to axle, you might call it poor man's four-link, there's good picture of them in 1200 competition suspension and they call them as traction bars.
