Hello. I have a 1987 Nissan Sunny with a 1.0 ltr engine which is pretty much roughed up. I'm looking to get an upgrade to a 1.3 EFI engine. Any suggestions on what should I be looking for and where should I look for it? And any estimated cost for the upgrade with and without the change of gearbox? Would really appreciate any help in this regard. Thanks.
P.S. I'm situated in Faisalabad.
