im looking for upgrade turbo for 2008 subaru impreza wrx  whats best one and as anyone got 1 for sale 

Depends what your plans are, be aware the 2.5 isnt the most robust engine so you will only be able to ahcieve 300 ish before your pushing the limit.

A turbo from an sti (non twin scroll) will be a nice upgrade, but bear in mind above and you may need supporting mods, plus it will need mapping for the turbo.

i bin told i csn go to bout 350 at most before forging looking for 330 its on 270 at min 

at min ive got full decat exhaust uprated intercooler uprated fuel pump k n cone filter forge blow off valve just got hold of sum deatschwerk 750 injectors to go on

A vf48 will get you 330 - Its standard on the STi and I have got one running at 350 with minor changes:

Cosworth Panel filter

HKS Up pipe

Cobra decat & full exhaust system.

Standard STI intercooler and standard injector size (550)

 

Feedback from TDR Warwick when they did the tune was there is more to come as breathing very well but the internals are standard so did not want to take it past 350 before forged pistons etc 

yes i herd internals are ok for bout 350  im looking for 330

A vf48 should suit your requirements, have a word with Fastline Turbos Northampton. 

I might have a vf23 from a 22b. 

For the right price, Obviously!
