Yeah I know all the different models available, my rep showed me all samples the day the turbo was available. They are a great setup but you still have to go to the trouble of changing the dump, oil and water hoses and intake. The only difference is you save money on not having to buy an external wastegate. They are limited in their flow and response due to the internal gated setup but make for a great upgrade on the 25's. Definately wouldn't recommend one of these on a 20 unless you have some major port work and other head work done.
If anyone is chasing one of these turbo, let me know. I should be able to beat anyone's price.
