hey friends i m from Malaysia, hope to share something with you.

recently i have swapped the original strut set to S13 strut set. these are several things have to be done:
1. coilover. as the original S13 spring is too large in diameter, i have to use coilover.
2. S13 knuckle and disc brake.
3. S13 lower arm. the castor rod mounting is not same with sunny's, so i have to drill new ones. this job is hard to me as i have no experience in drilling. the bushings is also too large, so i found some bushings that fill up the gap between bushings and the bolt.
4. Brake hose is also S13.
5. Sway bar mounting also not same, but i just simply plug on the nearest hole, wondering any negative effect?
6. Tie ends are still in progress to find out. the sunny tie ends are too small to fit in S13 knuckle arm, therefore some free play occur. if i tighten it too much, steering feels heavy. now i want to try the combination of B310's and S13's tie ends, when can be easily combined or must be engineered.

since the 1200 and 120y share the same mounting, i think it will be a good choice for strut conversion. hope can help you.

Hi dongdong0507,

Was your B310 with A12 engine? The A14 models already have large brakes (strut and brakes same as A10).

Coilovers is a good way to go. Alternatively some will fit the B110/B210/B310 spring cup to the strut and use the stock 110mm springs. But coilovers give you more room for wider tires, as well as more room to move the strut with adjustable camber/caster strut tops.

Hi ddgonzal,

My B310 was A12 model, the disc is measured at about 210mm. A14 hub is not same with A12 right? my friend found this few days ago.

i did consider to modify the S13 original absorber to smaller spring that i can remain more comfort. But seemed that nobody wanted to do this for me. they said it is risky. now my ride is really bouncy when i drive on uneven road.

now my problems is the tie ends. i saw people has done conversion such as from 280zx into 1200 right? how do they modify the tie ends?

thx.

B310 w/A14 uses same hubs and brakes as A10/Stanza model: 245 mm brake rotors. By comparison, B310 w/A12 uses 220 mm brakes.

For coilovers, you can get comfy springs. You want 90 pounds/inch the correct length. 200 pounds/inch is for racing.

For these strut swaps, I hear they use 1976-1978 B210 tie-rod ends -- they are the same as Datsun 610. Or from a B310 with A14 engine.

90lb springs will make your car handle like a standard Datsun, which isn't very good... I'm guessing if you went to the trouble of converting struts you want some sort of improved handling. 200lb is a decent compromise for ride and handling on the street - bit soft for racing.

A friend had S13 struts in his 1200 sedan.Here's a link to his thread about the conversion:

looks like he used S13 tie rod ends.

Thanks L18_B110,

I used Craig's post to start a new wiki: S13 Strut Swap. Everyone, feel free to add to it.

thx both my friends for the information.
today i found new solution from my friend. he said use AE86's tie rod ends, and machine it to fit original 120Y tie rod ends.
i will give more information after i successfully modifying it.
cheers.

here are some pictures of the setup. the tyres will hit the fender even with -3 degree of camber. the rims are 14X6j offset+15, which is not too deep. but with the extra 5cm long lower control arms, it looks good!

However, i can feel that it lose some original fun as the parts are not original. but i like the way in corners. the spring are 6kgf/mm, which are about more than 300pound/inch. next plan is changing it to 200pound
