Hey guys my motor was just installed the other day and I pulled two plugs out and they were pretty white. The car is running on stock 00Si injectors and stock ECU. Whats wrong and what do I need? Thanks

 

you need to get a B&M ajustable FPR and set your fuel pressure to 50psi.

get a colder spark plug, your proably running to hot

 

um, no - he is probably running too lean...

go 310's atleast, stock injectors max out at ~6k

 

Thats what I did and my air/fuels are in the green.

 

How is that possible when stock redlines are 7k+?

 

That's a False statement, Do you have any proof why stock injectors max out at 6k? Also I have talk to many crvtec builders and they all say it depend on your set up. If you are going to build a mild crvtec set up then stock injectors are fine and you just need an FPR. You only need aftermarket injectors if your set up is wild.

yes, on the dyno, i maxed em out at 100% duty cycle at ~6k on stock psi, and i have a very mild crvtec setup

 

I think that was your problem.

 

LOL!

happy leaning

minimum FP for a crv block and vtec head on stock injectors = 50psi

exactly why im not at stock psi, im at 50, but even than, cant go much past 8k or so

 

Yup, 50 psi + 310cc injectors = your good to go

 

on our stock b20vtec the stock 240cc injectors were hitting 90% out at 7400 rpms and going full open at 8000. monitored with the aem ems btw... we put in some obd2 prelude 290cc injectors and the max duty cycle they are seeing is 78% with 42 psi fuel pressure
