DSM 450cc injectors?

[B20CIV96]

I have B20 block/B16 head in 96 civic. i've heard that you can put DSM 450cc injectors into my setup but requires some parts. would this help since i have a chipped p28 already (just looking for more power in fuel delivery) or the 240cc enough?

are you still N/A or are you boosting?

240s will support 200 whp on 40psi of rail pressure.

not at high RPMs tho...

The problem starts up top (6800+)... My homie Nick has a set of 450s on his B20vtec CRX w/ a chipped P28 and has them widebanded really nicely. The biggest area of improvement was up top where the 240s struggle to deliver enough fuel in the limited amount of time available at high RPMS.

Tuning a car with 450s is considerably more challenging than tuning a car with 240s or 290s or 310s because all the part throttle conditions that are so hard to tune right don't resemble stock due to the larger injectors.

i'm still NA but looking to boost (internals have been changed).

if you plan on running any serious boost, 450s aren't going to cut it. Think 550s, or maybe even bigger if you wanna play with bars not psi.

yeah, i'd wait until you have a setup picked out and getting underway.

personally, i have 860's in my car.
