I don't have an ITR, but have a friend who just picked up an ITR engine thats going into a civic and he wants to know what the stock fuel pressure is?

If anyone can provide me with this info, i'd appreciate it. Of course, i will tell him to get a Helms manual for any other information he might need.

Thanks,

47-53psi

 

In the range of 47-54 psi is pretty much what the manual says, from what I recall.

 

I recall a Mugen N1 ECU for sale too!

 

Steve, one of these days it will be gone ... as will the good deal on it!
It will be out of my car for emissions testing in about a week or so. hint, hint!

 

I thought it was 43.

 

Thanks for the prompt replies guys.

You're going to make me go out to my car and get the manuals, aren't you!?

You're welcome, Mark.

47-54 or 49-55 somewhere in that range.

you CANNOT measure pressure with vacuum on the regulator...... but some of you cant read

 

i stand corrected (with my vacuum hose off of course )

 

I wonder how many times SGT has posted the same exact answer to these threads...

 

Out of 1317 posts - probably 700.

 

With idle vacuum its right around 43-44psi.

 

What I've seen on my R when it was still "virgin" was 42-43 psi at idle and about 52 psi WOT. This was with the stock FPR, vaccum house connected, and the B&M gauge at the fuel filter.
