what does NA tuning mean and how can it help my b16 sir2

how is it done

 

NA = Normally Aspirated = no turbo or supercharger

Still a relative n00b here, but NA tuning to my understanding is about increasing power through means such as replacing intake, header, exhaust, increased bore (and thus increased displacement)... as well as handling thru suspension, tires and wheels, sway bars, stabilizer bars and the like.

If I'm wrong about anything, flame away.

 

tuning your engine is done through managment of fuel, timing, etc. to maximize hp.......usually consists of tuning yoru motor through VAFC or Hondata and a set of adjustable cam gears.

 

Chances are if its stock, its most likely tuned. What you can do is do the usual bolt on I/H/E. dont try to change VTEC engagement for the B16, it is already optimized to engage at around 5.5k Just my thoughts on it

 

:doh: Its "Naturally Aspirated" :slap:

 

All of the above, generally done on a chassis dynamometer ("dyno.")

 

see? yo soy n00b. thank you.

:doh:

 

the biggest change for an na engine will be compression. finding the optimum compression for your engine without relying on race fuels.


normally people run up to 12.5:1 compression ratio. maybe 50psi fuel pressure and slightly larger injectors (slightly)

a general rule is the higher the compression, the higher the octane you have to use. 91-95 octane for 12.5:1 is sufficient.

also tuning the car depends on what altitude you are in.

for instance a car dynoed in colorado will dyno differently than one in florida. altitude and pressure plays some role considering the engine is relying on atmospheric pressure to 'breath' with.
