about 6500 RPMs. You have to really push the turbo for it to spool! HAHA just kidding bro. Your in nashville eh? Im down south in franklin.

It should spool that quickly, but my friend has the factory unit (A/R.80) and it won't spool until 4500 rpm. No one can figure it out... turbo doesn't leak, and once it finally boost, it moves! Why does it act like a T3?I would clean the MAF, unless your're going w/ the Z32. If you're running the B.O.V atmospherically, you'll need to use a Apexi SAFC- II. Otherwise the car will have incorrect air/fuel ratios, and die at every stop light.Good Luck!

stock boost on a t25.

when i take off slowly and then floor it in 1st gear. my car will not go ANYWHERE until i hit 3500 rpm. after that it just takes off. so im guessing full boost at like 4000rpm or something. (i dont have a boost gauge yet)

but that is with stock turbo elbow, stock downpipe, stock restrictive *** exhaust. im prettty sure my turbo will hit full boost at like 3000rpm when i go 3" piping from the turbo back.

Actually bro your wrong about the BOV. Mine dies like once every 1000th red light. If it does act like its gonna die give it a little gas.

Mine only dies when I'm at a high rev then put it in neutral... which only happens when the ricer side of me pops out every 100 years.

Have you checked compression, maybe your only running on 3 cylinder... long shot (very unlikely) or take it to a reputable shop and let them rack their brains over it.
