A billet batmo wheel turbo t-4 66-87-1.10ar. They say the upgraded 87 light weight option tw will spool like the standard 83 tw. They also say its good for 900-1000 hp. What do you think? What kind of hp do you think I could make with what's in my sig? And how streetable for a dd do you think it would be? Going to spray it as well!!! Also if you could anything I have to make it better, faster, stronger, etc., what would it be. Mainly going to dd but will occasionally pull it. All thoughts, suggestions, opinions appreciated. Thanx and have a great day.
