hello guys , how are you hope you all feel fine , as some of you know am not a mechanic , so i will ask those who have good info about turbo upgrades ,

am running pair of GT3076R Turbos with T-31 exhaust housings
and 3" machined compressor inlets , 2.5" turbine housing with 4 bolts !!!!

i would like to upgrade my turbos and swap the .63 and run .82 A/R housing !

so the question is :

is swapping the old T31 2.5" housing with new T3 , 3" V-band Turbine Housing is better ??? or it will be the same power since the turbine wheel will not be changed and will remain 2.5" ??????????????

i will get v-band clump and weld in into my exhaust to fit the new turbine housing


thanks in advance

 

Not to be a dick but .... Porsche Forums!! and with a larger housing you should be able to push more boost and spool quicker if im not mistaken meaning youll be able to put more power down

 

At the very least, check out the other cars section.

There is a power vs. spool tradeoff when swapping turbine housings with different A/R's. In general terms, and everything else remaining equal, the bigger turbine housings will free up some topend power, and reduce EGT's, but they will definitely spool up slower.

Why limit yourself by making only turbine housing changes to an old-tech turbo platform? Instead of merely swapping turbine housings, you might be better off having Forced Performance HTA 3076 compressor wheels installed in your present turbos. These wheels have an overall better aero and tip design than your current configuration. This will increase power across the board and improve spool up at the same time, even if you keep your current .63 fast spool housings.

Ultimately, an altogether better power producing option would be to upgrade your current old school turbos to a more modern and efficient platform such as the GTX 3076 turbo.

the issue about sending my turbo to make it hta3076 is they need to get the turbos out there on there workshop to do the upgrades , and as you know am far away ..

bs as many said it will be worth
