i m looking for a motor for a 91 sentra the GA16DE. 5 speed manual. please help . i m so depressed i broke my baby. and can you turbo that motor stock?

you can turbo it but not a whole lot. its a twin cam motor with nice forgiving design but not top quality parts. the connecting rods are pretty spindly. just get an SR20

the GA16 should take 10-15psi just fine.

Head to your local junkyard for a motor, they should be pretty common and cheap. Make sure you get a 91-94 though, or else you will need a new ECU and such. And I wouldn't put 10-15psi on a stock GA, I would maybe put 6-7, which should give you around 160 at the wheels, unless your engine just had a rebuild.
