I have some real fat injectors running on the car right now and a dx weak fuel pump. Sometimes when I floor it it feels like not enough fuel is being pumped. Also when I start the car after overnight my car would stall when I press the brakes (assuming brake booster) and when i give a little gas.

Should i go for stock fuel injectors? I'm only getting 250miles a tank on a 93 dx. My friend with same motor w/ similar setup w/ stock injectors getting 300miles. Would the stock injectors also help me with the stalling problem?

 

what are these fat injectors? 240cc OEM injectors are good. You don't have enough mods to warrant more fuel.

 

Your injectors hate you because you called them "fat," when really it's because your dumb *** bolted on a aftermarket intake manifold without tuning the motor for it - eliminating the butterflies and causing your motor to run incorrectly. Now who is "fat?"

 

so you're saying all i need is a decent tune? I had the injectors in there because I don't have my stock ones and just need one to run until i get new ones. Just wondering if that's the reason causing the problem.

Don't everyone call big injectors "Fat"? haha

Maybe they're plus size injectors.

I hear lane bryant makes them.

 

Just buy used stock 240cc injectors.

 

The fact that you're running "larger than stock" injectors and aftermarket intake manifold on a stock p72 ecu is where your problems are coming from. You should be using some sort of tuning like Crome/Neptune/Hondata etc to make those parts work properly. You don't need anything larger than a stock sized 240cc injector though. If you do upgrade the pump, a 190lph is more than adequate or you could use a stock Si/GSR/type R pump.

Your next thread is going to be"why are my rings washed out; its a big mystery."

 

Thanks for all of the info guys. I know the tuning will definately help it, but I'm just afraid that these bigger injectors will be overkill for what i'm using it for

Yeah, the "fat" injectors you bought are overkill but when you get your car tuned the tuner will be able to fix that problem. You basically just wasted your money on these "fat" injectors because your current mods don't warrant the need for them.
