Maybe its just me with my bad experiences with the stock turbos and "stock appearing" turbos that make me hate even the thought of removing or installing one. For the amount of effort required just to change the wheel id be expecting a heck of alot more than what its gonna give you. Like paint said...how much are you expecting from this wheel?
You can pick up a billet 4094avnt from danville for under $2K. So take the $400 from the batmo towards that, sell your stocker for $200-300 and not have that much in it.
Expect a gain for the first 20' from a dead stop, that's it. I've installed three, and that's all I noticed. A member local to me said he lost power on the dyno, but it was only around 10hp.
