Would a 275cc DSM blue top fuel injesctor be an upgrade for my 93 Honda Del Sol 1.5L? Thanks in advance.

 

Blue tops are 450s. 275cc wouldnt be much of an upgrade because stock is 250cc.

 

there's no need to "upgrade" your injectors unless you're putting more air into your engine and in need of the increased fuel.

 

If your setup doesn't necessitate more fuel, an injector "upgrade" won't benefit you, regardless of what injectors you choose.

 

stock OBDI 240cc injectors are good on NA cars for up to about 180whp without issues with right fuel pump.

btw. DSM injectors require a resistor box to be wired even to work. Then ECU needs to be reprogrammed/tuned for the setup otherwise you're just flooding the cylinders.

 

yes it is a larger cc than your stock injectors. they need modification, hit up the search buttom under the archvied section. its all there ,everythign you need.
