how to make turbo spool sooner Options

[batcavee00]

im been wondering how to make my turbo spool faster, so i been searching a lot and all i find is junk. some say to port my exhaust inlet some say not to do it. other say so upgrade to bigger exhaust piping....... its confusing..




has anyone here actually tried doing something like that and notice any good results?


i ask this because my turbo starts spooling at 3000RPM and i reach full boost (11psi) at around 3,800 rpm. i would like to reach full boost way before that....


i got a generic t3t4 .57 trim and i believe the exhaust side is .63 on my 94 gt, internal waste-gate w/ manual boost controller, 2 1/2" exhaust piping


all help is appreciated

thanks guys for all the info. i guess ill just stick where im at, i'll maybe just upgrade the downpipe and smooth out the exhaust turbine for now. i guess spooling at 3000rpm isnt that bad, the car still fun to drive.


what do you guys think about a t3t4 twin scroll turbo?

i got one of those ebay headers with a ct26 twin scroll outlet followed by a t3t4 to ct26 adapter, just single entry and then the turbo.


so if i ditch the adapter and get myself a twin scroll turbo, im sure ill be able to spool sooner. i heard twin scroll spool faster, so i was looking into that instead.




another question: if i have a boost leak, would that cause the turbo to spool slower? i start building boost at 3000rpm, full boost (11psi) at 3800rpm, then i get a small drop to 8psi around 4200-4400 rmpm and then it goes back up to 11psi from 4500rpm until redline.
