jgkurz Posted February 26, 2003 Share Posted February 26, 2003 Hi all, I was offered a potentially sweet deal on new turbo for my Z. I am friends with a local Audi/VW/BMW tuner shop. that does custom turbo kits and EFI's. They have an extra dual ball bearing GT58 turbo that they offered to at cost. All their turbos are done by Innovative so I'm confident it's a quality unit. Below is a list of my engine specs. The turbo I currently run is a Jim Wolf Sport 400 AKA T04E 50Trim Compressor with a 10 blade stage 5 wheel - .63 AR turbine housing. It spools very quick, but doesn't have room for big HP. Is a GT58 too big for my setup? I don't want a car built only for top end power. I'd like full boost in by at least 3K if possible. The car will be used on the weekends for road trips to the beach, autocrossing, drag racing and a track day at PIR occasionally. Someday I'd like to make 500 flywheel HP or more and I know my current turbo is wrong for that goal. Am I asking too much? Do I need to settle for a car that does one thing great, but not both?
