*alwayz_yummy: Meron daw dumadating na QG18DE from Japan pero bibihira lang. Madami daw ay yong QG15DE. If I'm not mistaken, local Exalta uses QG16DE.

Malabo akong makakakuha ng SR16VE N1 kasi kokonti lang ang mga ito. Mahirap din ang parts if ever magkaroon ng problema. Plus the price would be very impractical for me.

Isip ko tuloy kung salpakan ko na lang ng Toyota engine eh (4EFTE or 4AGE Blacktop) para maging Nissota ang ride ko.
A 4AGE 20V will cost more than an SR20. The older ones won't make as much power, and will require you to extensively modify (essentially trash) the car. An SR20 is a nearly direct bolt-in if you can find the right parts, and can be made to work with your original wiring harness and instrument gauges.

The QG16 will require a lot of modification to the harness and mounts, and will likely not work with your original instrument panel... a QG16 won't be much more powerful than the best GA16DE you can put in... might just be a difference of 5 horses or so.

If you're swapping for power, it's no contest... the SR20 is the way to go. If you're swapping for economy, there's no point, really, unless you've got a carbureted GA... and from there, it's simply cheaper to swap in a newer EFI GA.
