Bro I tried to find some info on the toyota A series and E series engine. some other fallows also suggested same engines in other topics.
The main problem with 4efte, 4efe, 5afe, 7afe etc is that their distributor is on the back side of the engine. When they will be fitted in a RWD car, we will have to cut the backside wall of engine bay.
Do you have any info about other nissan engines which are easily available in pakistan and can be fitted in RWD car.
One option is to overhaul the current A12 engine but the problem is that the carburetor and the transmission have some problems as well. Its gear oil keeps on leaking. we have checked all the seals but the problem is not solved. And the butterflies in the carburetor are not working properly. we got it fixed by a mechanic but now he is not available and other mechanics couldn't fix it.
your help in this regard will be appreciated.
Thanks
