Default bigger injectors

i was wonderin if the stock DSM 440 injectors would work in my b16a. I can get them for dirt cheap compared to new injectors.

yeah, but it will run rich as hell, and your mileage will go to crap. and i may be wrong, but i think they need a little modifying to fit. not sure how much though.

I think you just need to Dremel the seals out a little bit.

Check it out: DSM injector install.

But, like Sac said, unless you are boosted I don't think you need 440's.

hell, even light boost it would run rich. 310s would be more than enough for most street turbo setups.

You can run the 440's if you tune for them. You could run a garden hose in there if you tune for it, but you can't just drop 440's on a stock ECU. If you can get the DSMs for dirt cheap then use some of the money you save to get a really good tune.

that will help, but a professional tune would be the only way to get them right.
