What TB size should I be using with the GT35r .63 turbo?

Please advise me gurus.....


THanKs....

 

one that matches your intake manifold. with a big turbo more is better but only if you're gonna run race gas boost.

 

this may sound silly, wat if i port the TB to 65mm & port-matched the inlet of the intake mani....

I know tis might be a restriction & might not yield more horsies but the above setup of port-matched intake mani to the TB will it cause any unfavorable hiccups?

The race gas boost is taken noted of...

Thanks trinydex...!

 

that's not silly at all... you can't port the tb... no material to take off.. but you can buy one refabbed from br or works. the intake mani is just a matter of clever hands. this will yield more horsies up top when you open up that gt35r to its full potential, best is to use similar sized ic piping too.

wouldn't recommend this on anything but race gas type boost cuz then you're not exploiting the flow of larger passeges and you're introducing the lag from filling them.

 

Why would you want to change the TB?
It flows enough for the street and some serious power at the track.
Our stock Manifold and TB EVO put down 667HP with it.
Focus and spend your money on more important things like ignition upgrades and EMS.
Sorry my 2 cents.

 

Ok, Trinydex...Will definitely keep that in mind.....

So i wld assume myself to retain back the stock intake mani & TB if i am not using any race gas?

Please advise....

 

wow..667HP is no easy feat....& it is on stock intake mani & TB?!!!

wat sorta of setup u r at? turbo? cams? etc..etc...

i am looking at the HKS twin power for ignition now...& AEM is two days away from me...

currently, i am on 2.3L ams block with GT35r .63ar etc etc...
