alright so my question is i have a h2b using qsd kit h22a with b16 trans , skunk2 manifold with 70mm skunk2 throttle body and stock fuel rail stock fuel reg. i converted the injectors to obd2 style and took out the h22a 345cc injectors and traded for a set of of obd2 h22a4 injectors 290cc and iam bout to go get the car tuned and im not sure if i should keep these 290cc instead of the 345cc .... idk what i should do i was told by a few people that 290cc injectors on a stock internal h22a is ok any you guys out there PLEASE put in your comments and expereince with your h2b set ups . thanks

 

y downgrade injectors? especially if ur going to get tuned

 

also if i go with the 345cc should i get a bigger fuel pump

 

eg6 -because at the time i figured that all h22 injectors h22a h22a1 h22a4 etc. were the same as how all b series are 240cc i just assume lik a jackass they were they same . and i wanted to run the obd2 style injectors as i stated above instead of putting in the resistor box

 

some can b the same but not really sure..
but runnig bigger injectors for a motor isnt too bad of an idea.. going too big on a stock motor is overkill.. but 345cc r good enoughand better fuel pump is great.. may i suggest getting a new fuel filter as well

 

What gas will you be running?

 

93

 

slow eg i knw u knw whats up i seen ur post before on other threads . do u think i should keep the 290cc h22a4 injectors or get the 345cc the h22a injectors ??

 

Correct me if im wrong but the biggest stock injector is a 310 not 345cc for an h series, bigger is better in this case anyways

 

the obd2 h22a4 97-01 prelude injectors are 290cc ^^^ and the obd1 h22a1 injectors are 310cc and the jdm h22a injectors are 345cc

 

My jdm 345 injectors were maxed out with simple bolt ons on 93 I just had the factory fpr if I could of upped the psi a bit I might of been ok def get an upgraded pump

 

But I have 290cc off a h22a4 not 345cc

 

??? What u h2b guys with bolt ons running injector wise ??

 

Never ran stock injectors on an h2b setup myself. I had 650s on e85. I want to say you'll be okay but they'll be maxed out unless you find a way to bump base fuel pressure. But as of right now you couldn't with the stock fpr.
