I am going to be swapping a jdm h22a in my ek and want to run nitrous. My question is would I need to upgrade my fuel injectors and fuel pump? I have a turbo single cam in it already with a walbro 255 and motor has rx7 550cc with no resister box. Can I use the injectors on my h22a using this method https://honda-tech.com/forums/forced-induction-16/fyi-550cc-injectors-you-can-use-rx7-injectors-corolla-clips-456856/

I used that method for my civic no problem

 

upgrade to be safe. I would get bigger injectors

 

Id say your going to need some sort of nitrous system that will only spray during spooling.

Question seems too bland here. You should tell us what type of nitrous system you are using here, and your turbo set-up.

 

im not going turbo I just need to know if anyone has used the rx7 550cc injectors on there jdm h22a using the corolla clips like the method in the link i posted and as far as the nitrous I am going to be using a 75 shot and wanted to know if the 550cc injectors and walbro would provide sufficient fuel

 

I have never used them at all. I have just either had rdx injectors w/euro-r manifold then i went and purchase some 550cc rc injectors. I would go that route and you can get them high impendance or low impendance and dont really have to do alot of wiring

 

yea i already have them and dont need a resistor box thats y I was seeing if I can do the same for the swap

 

Tttt

if you're using a wet kit 75, you don't need to change anything else.
