is boring over/stroking really a practical mod?

what does boring and stroking really do for proformance is it even worth it?

On what motor.

a 4g63? , and if i was to rebuild my motor would that take miles off of it, or is it just a rebuild motor with 147,xxx miles still on it...because i really wanna slap a evo 3 16G on it , but i dont know if my motor can handle it..?

i own a 90' eagle talon awd tsi as far as the motor i thought they ran the 4g63t however to my suprise when i popped the hood it said hyundia on the engine what the hell is up with that? any ways im considering a used engine swap with a low miles 4g63 engine so what would be the benifit of bore/stroking that engine would it be cost effective i mean there are other mods out there that could give you 15-20 extra hp for about 300 bucks (cat-back exausts):2cents:

After a full rebuild it will effectively have 0 miles. But either way you should be fine with a small turbo like a evo16g, unless your compression is currently bad. I wouldnt even think about rebuilding if the compression is still good. ;) 1g you want 150-160 psi, 2g you want 170-180.
