    The VF series (VF22, VF23, VF24, VF29, VF30, VF34, VF39) are the most common direct replacement turbos. All VF-series turbochargers use the same roller bearing, water-cooled core assembly. The differences are in their wheels and housings to achieve different flows.

    The VF22 has the largest potential for peak horsepower. In other words, in the IHI model range, the VF 22 supports the highest boost levels. It is capable of running up to 25 psi. Because it is a roller bearing turbo, turbo lag is minimal...the boost comes on around 3300 rpm. Expect to max out the VF22 somewhere in the 400-450 hp range.

    The VF23 starts the middle ground. It comes on boost around 3100 rpm and is capable of running 20 psi of boost. Expect to max out the VF23 somewhere in the 300-350 hp range.

    The VF 24 starts to come on around 2900 rpm and will significantly improve power through the midrange over the stock TD04 turbo. However, the VF 24 is only capable of running around 17 psi.

    The VF23 and VF 24 are a great replacement for those who value drivability higher than maximum power.

    The VF29 & VF30 delivers a very wide increase in torque over the standard TD-series turbos.

    The VF 30 is a fairly new IHI model that utilizes the exhaust housing of a VF24 and the compressor housing sized between a VF 23 and a VF 22. It comes on boost down low (around the 3000 rpm range). With upgraded injectors, fuel pump, and engine management, the VF 30 is good for 365-390 horsepower. It is important to note that the VF30 is NOT a roller bearing turbo.

    The 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.

    One other turbo to note is the VF 39...it comes standard in the USDM STi. While we don't have all the specs yet, these are a new roller bearing, TWIN SCROLL design. Performance numbers are pretty similar to the VF34...maxing out just under 400 hp
    .
    so by this, it is most likely the VF39. I know it was the stock turbo that was from his car. I'll bring it with me to the next meet so you can check it out in person. I was trying to figure it out by checking on the IHI sight by comparing the part number on the turbo, but no luck yet.

    if its a vf39. you can use sti pinks and some kind of engine management. ive seen some wrx's with vf39 swaps and are putting down 270 280 hp

    yea a guy from the Renick dealer he doe'snt work there anymore had a 39'ed 03 and rode in it and did'nt expect much but wow it pulled hard and spanked an 04 STi it amazed me for a bare bones setup he had, he just had the 39, modded stock injectors an sti TMIC and Ecutek.....i'm going that route, but i'm getting the STi pinks for injectors



    and chris will u help me install them in about a month or so?

    good choice. you can never go wrong with sti injectors untill you max them out. and i have maxed mine out already. DOH

    big turbo = more air = more fuel

    ive already hit 100% injector duty cycle on some of my logs which means that im pushing them to the max. i still need just a lil more fuel. im thinking of going with some 650cc

    would a 39 max them out or does it depend on the aggressiveness of the map?
