Thread: 200sx walbro with stock motor?

It will be fine.

You'll be fine. Might be a wee but rich, but I ran mine like that for a few months and didn't have any problems.

i know for then i have my nitrous set up ill be using a walbro on my car

your base fuel pressure is going to jump by about 3-4psi with the walboro pump. so you will run richer than before.

I have a related question. I remember hearing once that our fuel pumps get "tired" That they got a hp jump from replacing theirs with a new walbro. Does that sound familiar to anyone else?

It's not a hp jump, the new pump just restores what should have been there. Will you feel it? probably not unless you got a fine trained as$.
