    i'm assuming it's a b18c5 that you're talking about, the b18c5's are much more responsive to mods than compared to our crap ass 1zz-fe's or even maybe the 2zz-ge's..

    also, an integra type r was build to road race, it has reinforced frame points compared to an integra RS, LS, and even GS-R, it came with a 22mm rear sway bar, front and rear strut bars, and an awsome ass 5 lug suspension (pwns j00 jspexae102 =DDD)

    the 5 lug allows better braking, some p1mp ass rims, and bling bling factor that all the fools on honda-tech love

    anyways, ITR is built to race, VERY responsive to mods, corolla, built to get 260+ mpg, thats bout it..it's comparing apples to oranges

    still staying on subject, the injectors with tuning will gain you horsepower. how much depends on a lot of factors. the more air AND fuel you get into the motor, the more power you produce. then think you want to burn that air and fuel mixture the best you can. then think you want to expel that burnt mixture out as easily as possible to get max horsepower and torque.

    more mods I need to have your opinion

    OK TAKE TIME TO READ THIS: my cousin and I where tuning up my car and told me to replace the fuel injectors like his 00 civicSI with an integra r engine and it made it run much quicker and better gas mileage he added a 360cc injector and some engine managers mapped it and before it dynoed 200bhp now its 245bhp but had less low end torque, SO PLEASE TELL ME if this will also work on our corollas i already put in a piggyback but made a gain of only 3bhp i will order if you confirm this.
    and how many CCs to achieve 180bhp like the XRS now its only 143bhp with the mods mentioned below.

    gaining horsepower off this is slim. your injectors aren't pushing over the normall 88% duty cycle so there is no reason to replace them. only replace injectors when needed. if they are maxed or 90%+...then go larger. this is not a more air more fuel thing.

    exactly, you will be supplying more fuel but not more air. You will need forced induction or nitrous to accomplish this. There is a certain ratio of air and fuel that needs to be maintained and adding a ton of fuel will just richen your ratio... making you lose HP and MPG.

    but if the engine is starved for air and fuel there is potential for more power. how does the motor flow? if it can pull in more air and more fuel can be injected into the motor then there is potential for power.

    from corolla performance: "The extruded aluminum runners have a much smoother surface finish than cast aluminum and are generously sized. Looking at the manifold up close, there are probably only two things that can be done to improve the intake manifold's performance. First, the intake runners are rather sloppily welded to the flange from the inside. The weld is a large, uneven bump all around the inner circumference of the intake port right where the manifold meets the head. Smooth out the weld, and intake flow should improve. The other obvious restriction is the throttle body, which seems quite small for a 1.8L engine. Some caution is in order here, though, since the idle air control valve and manifold air pressure sensor are both built into the throttle body housing, so boring it out too much may break open some cast-in air passages.

    On the down side (possibly), the extruded intake runners are thinner than cast runners, so drilling and tapping them for direct-port nitrous might be difficult. Welding on a small mounting boss may be necessary. On the other hand, the manifold is much more accessible for this work than it would be if it were on the rear of the engine."

    also think about running higher octane gas since the motor is at a 10:1 compression, there must be tuning to unlock power there.

    will a TRD SuperCharger make the mixture better and an injector controller maybe and i always use high octane gas and an octane booster when testing my car and i will need to buy the headers custom made and also a mild mannered muffler so it will sound like a v6 nissan

    better as in more mixture, yes. it will probably not be as atomized as a good naturally asperated motor, but there will be so much more air and fuel in the combustion process that it will be a huge increase in power.

    The TRD s/c'er is also designed to run very rich (10.5:1) to cool the intake temps, and yes... more air and fuel than normal.
