Here is what we found...
Spool-up?? rather poor, 3500rpm's to see 8psi.
Build quality? poor.. If you are going internal wastegate, you will have to cut and re weld the bracket that holds the actuator bracket, and also rotate the comp. housing. The front intercooler pipe smashes the top rad. hose about 1 1/2", not good.. I/C pipes fit terribly, nothing bolted straight up, and , many brackets were VERY far off, and could not be bolted down. Headers have port blockage which is not good and poor materials (unknown stainlees steel) not graded such as 304 or 321. The oil feed and drain lines were a complete joke.. They were made from copper tubing spray painted with oiling orafices that looked like a pinhole. I/C piping has no beadrolls and fit very poor, we're afraid to really crank the boost in fear of blowing pipes off.
HP? I feel many of our other TD04 guys would smoke a VF22 car..
Comp wheel size? smaller than a 357 mag. wheel.
All in all we were VERY VERY dissapointed with the kit to say the least.
Oh, and to top it of, the turbos supplied? they are USED, not rebuilt, not new, but flat out used. Both turbos did NOT spin freely, and one was really sticky, our standard bearing turbos spun more freely.
Take our review for what it is, a first hand experiance with the use/install.
