You won't get 930 power, but your increase will be substantial and quite noticeable.
From what I've read and been told, stock 930 power is achieved with only .5bar on a 3.2.

I have been planning my turbo 3.2 for about 6 months and the first stage is going to be very simple and cheap, about $3500. I'm only starting off with .5bar with the following parts.

• 930 J-pipe (sourced for $150US and bolts straight onto Existing heat exchangers)
• 930 Muffler ($250US 2nd hand)
• Garrett Gt30R Turbo and oil plumbing ($1400US)
• Protomotive Turbo Chip and Fuel Pressure Regulator ($700US)
• Charge pipe Fabricated (about $300)
• Tial Wastegate ($500)
• Blow off Valve ($200)
Total $3500

I'm sure there will be odds and ends I will need along the way such as welding different flanges on the jpipe and muffler but nothing too major.

I can't take praise for the design of this simple kit, Merv (WydRyd) divised it.

I just want to get it up and running as simply as possible then I can slowly upgrade to an intercooler, headers, MAP, more boost etc.
