I'm about to sell a turbo kit to a local guy and have a few questions about his D17.

Will DSM 450's fit?

Can he run a GReddy Blue Box?

Thanks.

DSM 450s will not fit. The only injectors that will are RSX, the design of the intake manifold and therefore the fuel rail pretty much make it impossible to fit anything else without some modification. There are one or two people running a custom Venom injector, but they had to do some cutting. Most turbo 7th gen civics are using an additional injector in the charge pipe.

I'm not sure about how the blue box works, but if it uses fuel pressure then it won't, the D17's are returnless and can't use any kind of rising rate fuel pressure regulator. If it tricks out the MAP signal to add fuel, then it might, but I'm not sure how well. I haven't heard of anyone using a blue box, so it would be trial and error on your part. Plus, the ECM's are very fast learners, if the map sensor and the primary o2 readings are not what the ECM thinks they should be, it will start to alter its own fuel maps. Some people with S-AFC's have noticed this problem.

If you're using a D16 turbo kit, the manifold will not work, the spacing and bolt locations are completely different, as well as the space available for the turbo and manifold.
