VF34 skulle jag tippa på och ja det är bolt on !
Med lite medvind och övrigt fin och rätt preppad maskin klarar den leverara unt 330-340hk !

Jo kanske kan stämma är lite osäker dock så levererar det ungeför samma effekt bara det att 35:an kommer lite tidigare och ska man verkligen maxa grejerna håller 34:an med lite längre men som sagt skillnaderna är marginella! Oavsett vilken det är så funkar den perfekt som uppgradering till en GT !!:-)

tjena om spridarna passar wrx 01 köper jag dom..

IHI VF34 (which comes standard in the Japanese market STi version ”RA”) is a new roller bearing turbo. It has the same specifications (compressor size, etc.) as the VF 30. The difference lies in the roller bearing which, theoretically, allows quicker spool and better response. It costs a couple hundres more than a VF 30. The VF 34 maxes out around 365-390 hp. It is probably the most popular option for big turbos on the WRX.
IHI VF34: This is IHI’s newest bolt on upgrade for your WRX. This turbo was originally introduced on the Limited Edition STi Type RA Spec C. As of 10/01, this turbo comes standard on all STi versions in Japan. This turbo features the same specs as the VF30, but features an all ball bearing center section for even faster spool (about 250 rpm faster than the VF30 according to IHI).
VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30.

IHI VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY.
