Ok here is the problem, i'm running a ls vtec wit gsr head and gsr tranny. my problem is when i'm racing in 2nd 3rd and 4th gear when it hits about 5-6k rpm on almost full throttle i hear the turbo spooling hella hard and it doesnt pull until i pump the gas a lil or ease up on the gas until like 1/3 of throttle... anyone think they might know what the problem is? i think i might be leaning out or something. the wastegate is 10 psi spring but it only reach up to about no more then 8 lbs. any help is appreciated. thanks in advance. specs are listed.

fuel pump?

 

yeah i have a bbk 255 lph fuel pump.
stock p72 ecu obd1

 

I guess its not the fuel pump then. I remember feeling what you described when I was running boost off the wastegate. Since I bought a mbc its got a lot better. Maybe its the spring on the WG opening prematurely and that is the loss of power you describe? Then when you lay off the throttle it closes a bit again? I dont think you could actually "feel" the leaning out so easily as you described.

I would buy a mbc. You could get to 10 psi and the wastegate would open a little later. I have the turbonetics and it holds 14 psi w/o problems. $40 bucks too.

 

well i ordered the turbonetics mbc and its in my garage now not installed yet... i dont wanna install it yet because i dont wanna boost more then what it is right now. i'm pretty sure i'm gonna blow if i boost anymore then what it is right now. let me know what you guys think, thanks

 

all that and you have stock injectors?

 

yeah for now until i put my internals in and 720cc and hondata.... i have everything already just gotta piece it together and get it tuned
