ok i have a 98 cavalier with the 2200 ovh and i put a turbo on it and its a T3/T4 57 trim turbo and i cant get it to boost fast enough to get
a good start at the track so is there any way to like get it to boost faster with out getting a new turbo ???
No I recommend adding another turbo.

A spot of nitrous could help, but you'll be better off with getting a different turbo.
its an old concept. time for something new to take the reigns. - Z yaaaa
get a wot box, may have traction issues after will def have to run slicks or d/r's
your running 18's with lo pro tires, tires and wheels should be addressed way before boosting up quick or your going to be looking at some axles from the wheel hop
running rich? turn the boost up
2 step with anti-lag? You'd need slicks to put that power down though.

thanks guys i will look in getting another turbo but what do i need to get what size ??? thats what i need help the most on !!!
Is it an auto or a 5spd and what are you doing when you launch? Like just mashing the gas or break revving(if auto) or if your a stick what rpm are you launching at?
its a 5 speed i launch round 3500 to 4000 rpm but i dont boost till i get bout to 5000 when i take off it will only only when i take off it wont boost till i leave the line it wont boost up befor so i can get a good take off ???
a t3/t4 57 trim should be boosting around 2500 rpm. check your wastegate or check for boost leaks.

Not necessarily.... What a/r is the turbine housing? What other supporting mods? Please also keep in mind, the little amount of boost you are running isn't helping either. You are nowhere near the efficiency range of that turbo....

i agree with QWK LN2, if your A/R ratio is like above .70 into .85 that turbo will be set for peak boost after mid range rpm.so it won't produce early on boost, as it will have turbo lag but will have less restriction in the exhaust.
ok well here r my Turbo Specifications
-Inlet Diameter: 3"
-Outlet Diameter: 2"
-Oil Inlet: 1/8 NPT
-Compressor Wheel: .57 Trim
-A/R Compressor: .50 A/R
-A/R Turbine: .63 A/R
Turbine wheel:
-Exducer: 2.48"
-Mayor: 2.89"
Compressor wheel:
-Exducer: 2.07"
-Mayor: 2.36"
and i have a 125 pis fulke pump with a 8:1 raito and i have NGK R spark plugs i rum 102 octain fule is this enough

I would check for a boost leak. Even if you have it bolted to a stock 2.2 or 2200 I would think the lag would be no where near 5k with those A/Rs

Its not really "lag" he is experiencing, but more so the result of being out of the effiency range....

So basically the low psi set on the waste gate is not allowing enough gasses to the turbo efficiently to spool it like it is made to spool?
