Looking for cheapest alternative... Engine is drinking oil and transmission has weird sound it does have 450000km on it so i think it is time for new one, d16z6 was my first option and i think im gonna stick with it, i just dont know if transmission from 1.4 would fit without much changes... I found one for cheap

All the manual d- series boxes are interchangable. The slave cylinder and starters can vary depending which model it came out of. I’ve got a gearbox out an ek civic in mine

[Rear seats with 3 point middle belt]

Yes I’ve got leathers in mine with a three point centre. I pulled them out a 99 mb saloon, the rear seats are all physically the same size but the rear tilt locks differ, think there’s 3x different types depending on year.

Have you considered just a gearbox swap? The d15z3 comes with a very long geared box for economy (3.7 final drive) swapping to one with a 4.437 short gear will help acceleration loads but the tradeoff is higher revs cruising on the motorway. You could stick a d16z6 in but without a short box it probably wont feel much quicker.
 

otherwise it’s whatever you want realy b or k swap
