I'm putting nitrous on my JDM b18c5 stock block. The setup is a dry shot. i have seen the other thread where people talk of putting about a 75 to 100 shot on. My first question is should i upgrade the injectors from what they are and what are the stock b18c5 injector size? I have already a walbro 255/lph pump, fpr, hondata s200, and fuel rail all waiting to be put on. I just need to know if i need to upgrade the injectors. Also i believe i can add more fuel when i need it through the hondata. if this is wrong please let me know so i can get a wet shot. thanks.

You'll need to upgrade your injectors to run a high dry shot like that. I recommend to go with a wet shot if your going with a single port. And by the way a 100 shot on a b18c5 is kinda high if its not direct port system.

ok. what size injectors do you recommend? will stock dsm ones work?

what makes the direct port better? i realistically will probably run a 75 shot.
I recommend rc 310 only for a dry kit if you go wet you will not need the injectors and the dsms will work with alot of tuning. And direct port is better because there is a fogger in each intake runner thus causing way better and even flow of nitrous. also if wet injector are not needed.

100shot is too high for that motor..compression is too high with cast pistons and the ring lands are too narrow..plus you dont want to run a dry shot that high..wet shot can run that high and its a lot safer to do so and you wont need to upgrade the injectors. direct port is better long term..but unless you are planning on doing a lot of racing with the car then its not really needed
