What is the injectors size on the vx cx dx and the ex si.... and for the best fuel economy would it be better to run the ZFR5F-11v-power those are the si one or would it be better to run the stock ZFR4F-11 for fuel economy... What i have is a 93 si with every thing si except the engine it a d15z1 and the intake manifold is a dx... I also dont know if all the obd1 injectors are the same size..

 

i know the 1.6's are the same size, the z1 vtec-e? idon't know. bump for an answer

VTEC+turbo= crazy
