why doo you mock the taiwan 20g like its something to stay away from? are you aware the blue car runs a taiwan 20g? It has proven to me it kicks azz. I run very little timing at rpm. this results in very high EGTs. has seen 1100-1200c many times . Its been boosted to 33psi many times trying to set boost curve . its got 8k miles on it boosting 23psi. no shaft play. not sure how much more proven it needs to be. do you know something we dont? let us in on it.

The td07 is huge turbine wheel. not gonna be a very good choice for a 4g63. they have been tried with 25g wheel and it worked no where near as good as the tdo6h/25g. problem is there are no small exhaust housings for that turbine.
