Yes, you will need either inline resistors or a resistor box to run the DSM injectors in your OBD1 Civic.

How much boost? It depends on the turbo, but it's more like "How much horsepower".

I think 300whp is the limit on the 450's. I know I've seen people make more than that on them though.....

Re:stock injector and dsm 450cc

Just up your fuel pressure on the stock injectors...
@ around 65 psi, your stock injectors should put out about the same as 450cc injectors at stock pressure.

Trust me, it'll work fine
