How rich will I be running if I dropped in the DSM 450cc injectors into an Integra GSR turbo with with a FMU (already did it, started it and shut it of to make shure there were no fuel rail leaks)? Is it damagingly rich? I have a walbro 255 high pressure fuel pump as well. Obviously a V-AFC is a good idea but what is the present standing? Does anyone have experience with this issue with or wihout a V-AFC application? Appreciate the imput.

 

My guess is that it'll idle poorly. Larger injectors + fatter pump = lots of fuel.

 

All I can say is don't do it.

I wouldn't do it, not without the proper tuning, and I don't know why you would use DSM injectors, why don't you just buy new ones. IMO do it right the first time, your begging for trouble if you don't.

 

I know it has been done before. I am hoping someone with direct experiece will respond but thanks non the less. Also, DSM 450cc are true to their flow rate. RC injectors in general have flow rate far below what is clamed .

 

Theres nothing wrong with DSM injectors...

I havent had them in without something to properly control them, and I wouldnt recommend it. Sorry man, no direct experience, but its really something that can logically be determined to not be a good idea

 

Thanks guys. I have not driven the car, it is evading a Wisconsin winter so I still have plenty of time to look for and install a control unit (most likly a V-AFC).
