Looking to by my new turbo this coming week. I picked out the VF30 but a friend of mine suggested going with the 18g and keeping the psi down tell I get the money for the tranny. Its a 05 WRX with the right mods going in with the turbo.

What do I do VF30 or 18g
Thanks for all your help

if you drive with any sense & don't launch the car the tranny will be fine. I would NOT buy an 18G & run it below 21psi.

18g will get you there, vf turbos generally will not.

While a vf34 can get to 300, you'll be tuning towards the edge to get there. I'd guess about 22-24psi would do it, and probably 565cc injectors + meth injection, or 700-800cc injectors without meth injection.

Look at my car as an example of a conservative vf34 setup.
