92 Camry loss of power! - Toyota Nation Forum : Toyota Car and Truck Forums

Ok i got a 92 5SFE with a few mods. CAI, 550 cc injectors, supra fuel pump, MSD ignition. Now the problem i am having is that since then i feel like i have lost a lot of power, and i have a rough idle. I think i have an exhaust leak but its not a big one its at the converter. My car has about 93k on it. Any suggestions on causes? New o2 sensor and about to put an acell coil and aceel wires on the car. Thanks for any replies.

its because your running 550cc injectors when you dont need it ... You only need such a big injector if you were running a turbo system...

I second the injectors.

Stock injectors on a 5S-FE are around 210cc's.

I will be running turbo soon thats why i put them in, but could they make that much of a difference where it would like cut my power in half. I am also thinking a clogged converter.

The 550cc injectors are way to big for a n/a 5S-FE. Their good for about 350hp (40 psi and 80% duty cycle).

So their causing your engine to run rich.

I would put the stock injectors back in for now.

yeah the guys are totally right....the 550cc injectors are too big for a na 5sfe. Those are even too large to tune accurately with an SAFC. Definitely go back to the stockers and when you drop in the turbo drop in some 440cc injectors, if you lower the fuel pressure u'll flow 420cc out of them and you can tune those with an SAFC. which 550cc injectors did you get to fit anyway?
