Air / fuel? or fuel pressure? what's more important?

[1Gina2G]

Hey everyone, I want to definatley make sure I'm ready for start up once I finish putting everything back together, I was wondering what would help me out more as far as making sure everything is %100 with my fuel system? A wideband? Or an adustable fuel pressure regulator?

I'm not trying to upgrade my fuel system full out right now, I just want to get running. I'm doing the rewire and changing to a bigger filter with braided hoses, on a stock rail & imjectors.

wideband first you should be ok to ride on the stock fpr till you can afford a afpr.Been rolling with a walbro 255 for years on stock fpr.

Did you read any of the posts in your other thread?

If you don't have a 255lph pump or bigger, skip the AFPR for now. A wideband has nothing to do with "upgrading your fuel system". It is used to monitor your actual AFR's and help to tune your car. It is always recommended to get one, especially if you have a tuning device.

You will need an Air/ Fuel wideband if you want some indication as to what conditions exist in the combustion chamber. From the sounds of it the stock FPR will be plenty enough. Do you plan on starting to tune the car? Did something happen to concern you with this?

You really will be fine with stock fuel lines and fuel rail and stock filter.
Just get your car a wideband, ecmlink, 255 fuel pump for starts once you save up for that then look into any size injector you want and any size turbo tune for no knock and hope your stock motor holds up boostin.Always help to do some research on what to do try not to post to many posts dealing with the same stuff.Dsm's have been around forever all the info is out there and everyone opinion is ganna be a little different.Get to saving up that money and start moding.Don't forget your maintanace.

I did and I understood. I was just wondering if it was even a bad idea at all to go out of the way to get one, before I started up to be sure. Honestley everything with the fuel system makes me nervous after reading about detonation. I'm a newb untill I learn

The only thing that you said that was different from what I have now is my fuel lab filter, bigger in size compared to the OEM filter and without the restrictive banjo bolt at the top.

As I was saying on my other thread...I learned running rich is still bad but not as bad as running lean, witch is why I'm also doing the rewire. I was just trying to figure out the best way to get an idea of how efficient the fuel system is.

Your car has a stock fuel pressure regulator, so running different fuel lines or a larger filter will not effect it. The regulator is still going to regulate it to a set psi of fuel pressure. It wont change.

You get an "adjustable" fuel pressure regulator when your ready to "adjust" your fuel pressure from something other then stock. Or because your fuel pump is so large its pushing through your stock regulator, which is called overrun. Overrun is rather overrated. It mainly only happens at idle anyway.

And that ^ is what I mean.Stock fuel system is really good and over looked.

I don't plan on tuning right now or right after I get it running. nothing happened to give me concern, I just want to check how its running upon fire start up.

Get the wideband... it is more useful for you at this point in time. Being able to monitor the car's A/F is key in warding off detonation; as then you'll know when it'd running too lean.

Wideband first

you really don't need either one at this point. A pump would be the wisest money spent if you have no link,afc, etc and stock injectors. Also keep in mind that you don't NEED a gauge for your wideband. In the past I've always had an in car fuel pressure gauge because I feel its about the most important thing to have in your face besides maybe boost. I've never had a wideband gauge or display in my cars, I've always just logged AFR's to laptop using the widebands software or through the ECU's software depending on the setup I had at the time. Right now I have an old zeitronix Zt2 from when they first came to market. I sold the Zeitronix display unit probably 9-10 years ago. I plan to upgrade to that new Innovate LC1 with the tiny controller integrated into the wiring.
