When tuners build a power package, it's HP that sells kits. There is no doubt about that. How's the car going to drive on your way to work everyday? That depends on torque. Old saying: "Horsepower sells cars, torque wins races." So why is the venerable IHI VF35 overlooked so much? Well, for starters supply and demand have made it one of the more expensive IHI turbos. Since IHI builds solely based on demand, the 35 still fetchs almost $1000 even today. So why not get a VF34 instead, right? Maybe not. If you drive an automatic, the VF35 is a far better choice.
I've taken a look at a few dyno plots for the 34 vs. 35 and the VF35 continues to impress me. It provides a near flat torque curve from very low in the rev range and pulls almost all the way to redline. ALSO, you can run it on STOCK FUELING and still reap a lot of the benefits of running a "bigger turbo." The VF35 uses a unique bearing and exhaust housing and spools VERY VERY fast, just as the TD04 does, but can handle 18.5 psi on track days (with fueling).

Want a Streetable Turbo...Shouldn't I Get a VF-35?
I'd like to hear some IHI VF35 owners chime in on this thread. I think the VF35 does not get the credit it deserves. If I can build some interest in this turbo, I'm going to run a groupbuy.
