Considering which turbo to buy to upgrade my 2004WRX. All the other parts are now in place so its just the turbo to buy now!!

Any opinions on the above two Turbos?? Which is best for power/spool up??

I have just bought a low miles vf28 for my 2004 wrx as you can get them a lot cheaper I paid £160 where as a vf 35 is around 300.I don't think there is a massive difference power wise maybe 15/20 bhp.whats the rest of your spec?

I dont believe there is a big difference though the 28 will spool a tad earlier.

Hey Shreksta hows things Buddy?

My spec is as follows on a 2004WRX

3inch Cobra track Friendly system with sports cat
NGK PFR7B's
STI TMIC
STI up pipe
STi injectors
Walbro 255

Still considering what turbo to buy and a re-mapp of course when all the above are fitted..

get a decent panel filter aswell,and a sti scoop with undertray,also a 3 port boost solenoid from a classic impreza,are you de-catting the down pipe?

the vf28 can push 340bhp but its near its limit really,i would be happy with around 325bhp for the time being as to not destroy the gearbox,im still deciding whether to have it on a rolling road or to get it live road mapped by andy carr and have lots of extras etc

im running an sti bottom end so in theory i should be able to get more power in the future with a bigger blower,is yours a standard wrx engine? have you upgraded the brakes etc?
