Ansar bhai,
I love 3SGE Beams dual vvti as a 4 banger as it has pretty decent horses (210 that can be bump up to 500 range) with 6 speed. As a matter of fact I have one waiting to be installed in my 73 corolla.
But if you are worried about it being pocket friendly then 3SGE isnt the right swap for you.
4age in my opinion is too small of an engine for such a big car like yours. But if you are not too worried about need for speed and given the road and traffic conditions in Pakistan that might not be such a bad thing.
Think of it this way with 4age you wouldnât necessarily need to upgrade your rear differential or totally upgrade your breaking system just change to cross drilled rotors along with ceramic pads and youâll be alright as long as you donât go ballistic on your gas paddle.
