rob has a point and diesel has a point also
if your going to max out the stock injectors your not really gaining any hp, ive seen people run 12.5:1 pistons with the oem injectors, however its not "safe" for an engine that is not designed for that kind of compression from the factory
you could do a somewhat cheap dsm injector swap, they are between 440cc-450cc
easyish to install making sure you get a proper seal in the intake manifold and injector will be the difficult part... can get expensive quick if you do not pay attention, im my area the kits are sold individually per injector and are 24 bux a pop!
heres a small list of the b series
b16a
Displacement: 1,595 cc (97.3 cu in) 1.6-litre
Compression: 10.2:1
240cc injector
38psi fuel pressure
10-13 ohm resistance
b18a / b
Displacement: 1,834 cc (111.9 cu in)
Compression: 9.2:1
245cc injector
40psi fuel pressure
10-13 ohm resistance
b18c1 (gsr) usdm
Displacement: 1,797 cc (109.7 cu in)
Compression: 10.0:1
240cc fuel pressure
45psi fuel pressure
10-13 ohm resistance
b18c (gsr) jdm
Displacement: 1,797 cc (109.7 cu in)
Compression: 10.6:1
240cc injector
45psi fuel pressure
10-13 ohm resistance
b18c5 (type r) usdm
Displacement: 1,797 cc (109.7 cu in)
Compression: 10.6:1
240cc injector
45psi fuel pressure
10-13 ohm resistance
b18c (type r) jdm
Displacement: 1,797 cc (109.7 cu in)
Compression: 11.1:1
240cc injector
45psi fuel pressure
10-13 ohm resistance
b20b
Displacement: 1,973 cc (120.4 cu in)
Compression: 8.8:1 or 9.2:1
240cc injector
40psi fuel pressure
10-13 ohm resistance
b20z
Displacement: 1,973 cc (120.4 cu in)
Compression: 9.6:1
240cc injector
40psi fuel pressure
10-13 ohm resistance
OBD1 92-96 prelude injectors run 310cc
you will need pigtails
they however 1.5-2.5 ohm resistance injectors so you may need an injector resistor box, i have never tried the swap and i havent really investigated to see if they are 310cc injectors are not.
hope this gives you an idea as far as compression ratio and injector size
