we try to upgrage as much as we can with the s12's, not down grade,lol,:D

Well that`s my plans for swapping loads of s13 parts onto my s12 out the window then :p ....LOL....

Its the actual s13 body and chassis which is a downgrade, Nissan used a much thinner and cheaper grade of steel on the 13 than on the 12. This maybe why we have seen s13s suffer from Rot more.

....LOL.... I was just joking Jon ;) .

But that does explain why there seems to be a lot more road noise inside the 13 compared to the Silvia if the panels are thinner.
TBH, it`s mostly the oily bits that I`ll be using anyway.

I guess that`s typical of a lot of car manufacturers though, to cut costs like that :( .

its still a good bit heavier than the s12 though, is'nt about 1240kg ?

no idea but abs systems weigh a fair bit alone

What is the stock weight of the S12?

dont think there's much in it, the s12 rear subframe and diff assembly is loads heavier than an s13 one, probably a good 30kg extra.

Only thing I'd say was a real big step forwards from the s12 to s13 chassis is the suspension. Just a shame its not an easy swap

mk1 s12 is 1135kg, mk2 is around 1175 / 1210kg, i'd have to look in my book for the exact mk2 weight, my mk1 was 1235kg with the extra weight of the skirts, bonnet and that rear wing.

Does anyone know if the S13 slave cylinder fits on the S12 please?
