Yes, turbo has a lot to do with it. 10psi on a Holset HX40 would easily max out 450s while 17psi on 13g probably will not.

To answer your question, it depends on the turbo. Invest in a pocket logger at the very least and check for yourself.

 

This has been BEAT TO DEATH.

Do ONE search.

 

You also need to learn to follow rule #7.......

 

For a minute i thought i logged on to dsmtuners by accident...
Crank the boost controller all the way and let's see how far this guy can go on stock 450's.

 

This is not tech. I see JP has given you probably the best advice here. I suggest taking it, as you may have noticed all your posts that do not comply are gone.

 

Why do they never take two minutes to read the rules?..:dunno: I mean c'mon..even a high school punk like me took the time to read them.

 

Are you guys this hardcore about the rules over here? AWESOME!

In any case. 12 lbs to be safe, 16 if you feel frisky, assuming its a 14b, bigger turbo = more air flow = more air at lower psi = less boost on stock injectors. *EDIT*

Yes we are that hardcore about the rules, which include no classifieds transactions offered outside of our classifieds.

 

Are you guys this hardcore about the rules over here? AWESOME!

No point in having them if they aren't enforced. So it's either enforced or you'll be trying to read "mi dzm wuz goin fast andd sumbdin popd. Ani ideaz?"

I'll take enforced! I mean, no offense to 90gsx_luis, but he can always just remember it in the future. The mods aren't trying to scare him off..

 

^^^^^^^ That is all you should do. But i think that you should get a logger and maybe some other things to get before you turn up the boost.
They take the rules very serious here. But that is okay because it is a very clean

 

Well with my stock t25 and with my mbc closed. I could spike to spike to 22 psi then fall off to 12 at redline and I never had a fuel problem.(it's set at 14 now)

 

Oh yeah? So what you mean is you never hit fuel cut. Which sounds like bs to me, and you surely did not have any type of WB02 or logging capability. You don't run 22 psi on a stock 2g and not have fuel problems.

You are just not paying attention in the right places.

 

Iam running the 14B on my 2g at 12lbs. and iam havving fuel problems. So i dont see why he isnt. And Ive done most of the supporting mods as well.

 

Get pocket logger

 

I hit 20psi on the stock 450cc injectors with a ported evo III 16g, it was only once because my wastegate hose snapped, I immediately stopped the car and took care of the problem. It pulled like you wouldn't believe but I wasnt chancing my 4g63.

Just keep the boost at 12psi until you can buy the supporting mods.

 

I have 3 options for you.

1- Sell the car, 0 psi. If you can't read or do research, on these cars, imagine working on them... Sell it and get out now.

2- weld the waste gate shut and let us know, we might forgive you.

3- 15 psi and don't look back. Start reading, learning, and saving money, your going to need it, and possibly and English class.

 

Hi, im new here, ive got a 96 gsx, and im having this fuel cut out problem also. At least when i try to run over 12psi. My check engine light is calling for the upstream o2 sensor, could this be my problem because i have an air/fuel gauge but the car seems to be ok according to it. I can turn up the boost to around 17 and it pulls fine till about 4500rpm then its like some one turns the key off for a sec then im back in it till it cuts out again, any advice is apprecatted thanks

 

Turn the boost down!
Is your gauge a wide or narrow band?
Fix the upstream 02.
Where in MO are you?
