the best daily driver would have to be the 34... 18g is a big turbo and spools later than the 34. you would be making a lot more power with the 18g than the vf-34. You could always buy an 18g and then have deadbolt (www.deadboltspeed.com) monster port the turbo to make it spool a little quicker.

 

just tuned my wagon yesterday (been running wastegate pressure for a month), so don't have too much seat time with it. went from a VF30/STi pinks to an 18g/UR785's. EM is a Cobb AccessPORT and now with the StreetTUNER. the 18g spools very similar to the VF30, but has ALOT more boost available. at the same point that i hit 16psi on the VF30, i can hit +18psi on the 18g.

 

can a vf34 put out 400 on an sti??? (hp) wat supporting mods, besides the basic bolt ons also??? im mad cuz, drivers image has a 400whp sti

 

im thinking no but i dont know much

 

pm jerry at deadbolt he helped me choose my turbo and im stoked
