I've been scrolling through alot of the pages in this thread and couldn't find many people using the TD06H 25g at all. I've been trying to read up on them for a few weeks now. I have a Rb25/30 that is just a slap together engine pretty much that I had tuned with a Kinugawa td06sl2 20g 8cm. Although it has pretty much instant boost, it lacks of go up around 5000 RPM, I normally don't rev it past 6000RPM. It also wasn't making any more power above 16psi (304rwhp) with a 38mm External waste gate welded to the rear housing.
I drive the car atleast 3 times a week on the street, Gymkhanas, Time Attack and Drifting. Im not really after alot of lag.
What I want to know is how Responsive will a H 25g 10cm be, Will it make full boost by atleast 4000RPM? Does any one have any experience with these on a RB25 or Rb25/30? Dyno sheets? I'd love to hear your experiences!
