i dont want to get into another pissing match, but i would SUGGEST, that you don't try to make more than 200whp with those injectors.

so i suppose if you keep the boost really really low you might get away with it,

kinda like the saying, dont be stupid, wrap your tool. Same thing applies here. Donn't be stupid. Get the larger injectors.

the stock are 290cc , if your using an fmu i wouldn't go anymore than 6 psi max , if your using real fuel managment you with be at 100% duty at like 2 psi, the stock injectors are close to maxed out when the car is n/a.

buy some injectors

ur asking for it.

not smart at all. Its about 50 bux for a set of DSM injectors and about 40 bux from RC for OBDI injectors clips. Doesnt it seem kinda dumb to try and test your motor just to save 90 dollars?

U spent all this other bullshit money on your car that dont even do anything. Now you are wanting to save 90 dollars on something that WILL save your motor?

have to agree with 98vtec, for the sake of $100 worth of kit its worth it. do you not think it would be nice to have a bit of a safety margin for your fuelling rather than "oh **** i hope i dont gas axe a hole in my piston"

this is why i say what i say.

hondas come rich from the factory. they also dont MAX out there injectors like stated above. i looked up on crome an for a p13 all the way to 7500rpm, the duty cycle is only 25%. now givin that more likely not 100% correct. im thinking like 50-60% DS. now only ading 3.92 psi of boost should put me in the 80% DS area. now I think for 2 months of steady drivin it should be ok. An i dont want to waste the money on something im going to get rid of in a few months.

But i do understand saftey first. but i think im safe for now on tese injectors. ill be tuning it with a wide band, so guess wheel see what it has to say here in a few days

if i were you i would buy some bigger injectors, its just easier, i know you want to save money but i dont think fuelling is the place to do it, if you do decide to keep them stock you could always bump the pressure

oh i em. running a walbro 255 with a BM regulator. i have it some because of the old nitrous stuff.

getting new injector would be 100% safer. I agree. but if i buy injectors im buying some 750cc. i dont have the money right this second. like i said, if i dont beat the hell out of it i think it should be fine for 2 months. not even. like 1.5 months.

im just goin to make sure my timming is on point.
