Default Psi without fuel return

I remember seeing this somewhere but cant seem to search it out...

I am most of the way through my greddy tt install.

I made the decision to get married in the fall. So I need to keepy parts buying addixtion at bay for a while. I am wondering if I can just run low boost,.stock pump and greddy 440s, and forego the frs till next spring after the wedding. Is it safe to run any fi w/o a frs? I did it with my pricharfer up to 400rwhp bit thats not to say it was good on the engine (short story: boom, rebuild.)

8.8:1 cr
Forfged everything
Bc stg ii cams
Utec w/map sensor

Can someone help me out with this or provide a link to the topic that,enivably already exists on this subject please?

first, take your time and spell correctly, second get it tuned with the utec, no fuel return is fine for low power but not ideal....

A basic is $400 from CJM, if you can't afford that, then you shouldn't be boosting a Z.

First you have to have a walbro 255 fuel pump and then get it tuned with the utec.I have been running this combo for almost 6 years at 6psi but went with fuel return at 9psi.

It didn't work with a supercharger but you think it'll work for twins? Kind of like being impotent around a single woman and thinking you could suddenly dazzle two with the same inadequate- ahem- hardware.

JudgIng by your history- this is not a threesome I'd want to watch.

And at this point it's not a parts addiction: it's doing what is needed to prevent blOwing your motor (again) and getting a reliable return on your investment.

Simple answer, possible: yes, good idea: no

...should take own advice, I'm on stock block with twins, 7.5 psi at the moment and only a walbro 255 an dw600 injectors. It works, but one of my next investments will be a full RFS

Man look at all that attitude. My first engines demise had nothing to do with fueling. My mistake came when a vac hose came off . And caused an overboost situation. I had a 16 psi pulley on with a 9 psi w/g just before the ic as a pop off valve. No I never broke a belt.

Thanks to all that had opinion w/o attitude. I forgot the cjm was upgradable. Thats awesome. That could be my solution. Thanks for suggesting that I look into that . I had planned on a cjm stg 2 but I guess I didn't look at it lately enough to realize it was upgradeable. I do remember that now I read it.

Please, everyone, no more attacks on my character or mechanical background/prowess(lack thereof)

First of all: "we seek advice when we know the answer but want a different one."

Second- read your own initial post and show us where you say that your first blown motor had nothing to do with fuel.

Oh wait- you can't because you actually say that you've done this once before and blew up your engine. Boom- rebuild... Why? Oh- because you went without frs before... Not that it was good for your engine... Yeah. You know the rest.

So before you get all up in arms about our attitude, maybe take a look back and evaluate why you're on the receiving end of it.

+1 on everyone's post. To be honest bro, shouldn't you be putting that money into the wedding rather than the fuel system? I would put the project on hold imho because there are other expenses you have to worry about. Just saying. Don't skimp on parts when you finish the build. The fuel system would definitely be in the process of my turbo build and not later. Without enough fuel, you won't be able to push more boost. Good luck.

save for a cjm stage 0, bigger injectors, fuel pump, tune. do it right the first time and you'll save more $ in the long run...
