Default LS vs. H22 Injectors?

I'm asking for a friend... He has an LS Integra, and is thinking about putting in H22 injectors... we've heard good and bad things about changing them over... anyone have any opinions? Some have said you will get more power, some have said you will lose power... just wanted to see if anyone has done it or knows how this works

if he only has bolt ons he isnt going to see a damn thing from putting them in but whatever. i believe the 97+ lude injectors are 290cc's and the 92-96 are 345cc but peak and holds.

exactly what was said above, if he only has minor bolt ons: header, intake exhaust, there is absolutely no point because hes not gonna run lean with that, now if it was turbo, super charged or had a little juice, it would be different, cause he would need the fuel, but if he only has bolt ons then there is no point.......

as of now, he only has bolt-ons... zex is on the way though...? Would it be a good idea to get the H22's for the zex?

.

you have two people on the spray now that will vouch for that. stock injectors are fine unless he wants to spray a 75+ shot.

fuel pump would be the better choice.

question related to this topic: what if he had some internal work done? like camshafts and raised compression that runs on street gas? but not so much literally his car & engine, but any 4 or 6 cyl thats under 3.0ltr.

basicly, if you gained 20-30whp on the dyno from internals alone, plus the bolt-ons, would you see a gain from bigger injectors then?

he will probably use a 75 shot at the track, 65 elsewhere...its not a question of whether or not the stock injectors will work, it was just a question of whether the H22's would hurt I guess

I'll let him know
what you guys have said thanks for the help!

doubt it. you'd be better of spending the cash on tuning the stock injectors. i mean the bigger injectors wouldnt hurt if you tuned them, but the stock injectors would suffice...because honestly...20-30whp isnt much...

LS with Bolt-ons with Zex, no need for H22 injectors.
All you need is a Fuel pump & Adj. Fuel Regulater & your good to go.
