Hi, iv got a 2003 impreza sti, iv had it remapped to 325bhp, i believe im running a VF35 turbo, what would a suitable turbo upgrade be to get me to around 380-390bhp?
What injectors would i be running as standard and would i need to upgrade these also?

thanks

 

scoobyclinic sc38 or a vf48 from a hatch sti

 

How much do these go for roughly?

 

a used vf48 goes for £350-£500 there is one for sale at the minute in the forsale section i think

as for the sc38,ive never seen one second hand.have you looked at this before?

The vf48 is now sold, would a vf43 be any good?

 

not sure mate to be honest,remember its not all about numbers,you could have a car with about 360bhp thats properly set up and sppols like a ******* that will spank a laggy 380+ bhp

 

I run a SC46 @ 429/380 on v power on my 03 STI using Lateral Performance STI Pink injectors if that helps you?

 

Thanks for your input Jacko4130 but dont wish to go that far, only really wanna change turbo (and adjust the map) so get 360-390bhp.

Is there anywhere that has turbo info, ie turbo number and what power its rated for?

 

Try an SC38 ?

 

Whats the price on one of those?

I'm looking to upgrade to an sc46 so my sc38 billet will be up for sale soon!

 

Thanks but not looking to spend anywhere near that sort of money.

 

You may need to re think your ideas then...

 

Why, someones already stated an upgrade turbo is £350-500 which is a bit different to £1170.

How much will your turbo be the pooch?

 

It unlikely you'll get 380+ from a vf48 on a 2.0, possibly on a 2.5. A TD05 20g is probably you best bet on a budget.
