Right basically my saphs got a twin port actuator on mine, seeing as no1 else seems to run one/know much about them and most tuners dont seem to use them im thinking of taking it off and fitting a normal setup, so basically for a t34 .63 housing running greys and standard cams what would be better, a -31 or -34 actuator?!

 

-34 i,d go with on a T34 Turbo...

 

well i'm running a -34 on my t4 and it comes in alot more aggressively then a -31 so makes it more fun to drive lol....

 

34 all the way.
