Cost for the FG Turbo upgrade to the MTA center and new billet wheel balanced (MTA 650 Model): $1100.00 and 12PSI Actuator $130.00 I think from memory to upgrade to a bigger turbo is around $2000.00. But depends what you want to do with your car to which way you should go. If the FG was just a spare car for adrenaline fun and just generally did track time you would go balls in and go bigger turbo and strengthen a lot of other running items on the car. With supporting mods build might be around $20,000.00 If the FG is a daily driver and also want a track weapon free flow (upgrade) the little turbo. With supporting mods the whole build prob around $12,000.00 Prices are including brake upgrade which will cost from $3,500.00 to $5,500.00 unless you get a lucky EBay break that can bring that cost down to around $2.500.00 all fitted prices approx.
