Just swapped B20 into EF...help me make it run better!

[EK9]

i just swapped a b20b into my ef...it runs and everything and ive driven it but when i drive it it seems like it doesnt quite feel right. it feels like somethin might be holding it back...Also the CEL is on and i have no idea why. If you have any ideas as to what i can do to make it run flawlessly and to get the CEL turned off that would be awesome.

let me know if you know anything

is it flashing any codes??

[Mr_ET]

if the cel is on it's flashing at least a code. Once you have a chance to check that out please let us know what the codes are and we will go from there.

Also is the b20 breathing through your stock EF cat and exhaust?

kinda need the codes.
whats a good exhaust size for a 2.0l?

I'm running 2 1/4 piping on my B20 setup, seems to be real good.

[Mr_ET]

I would run what Deetz is running if you plan to keep it fairly stock. If you plan to swap a vtec head, it might be an idea to look at 2.5 inch piping.

If you don't check the codes, there's not much help you can get online.

What ECU are you running?

autovalue might be albe to give you a hand with checking the codes, I say might because its a swap and it might not come up

edit: if not than do the old school way with the paperclip
there's a sticky on how to do it in this section

yah ill check the codes as soon as i can...the car is at a buddys house and he is away for the weekend so i cant get at the car but as soon as he is back i will check...i just need a paperclip right and it flashes in long and short and the long flashes are 10s and the short ones are 1s right? so example 4 long flashes and 2 short would be code 42 right? I am running a PR4 ECU on my b20. Yeah i am using stock exhaust which is most likely the problem with it not having as much power as it should lol.
