Welcome to the boost.
A build Can be done way cheaper then. 8k.
Stay under 475-500hp the stock tranny will work but will need a shift kit and servo.
I can do a kit with injectors and a walbro 255 for under 4k.
Would be limited to the 450 range on power.
Then as funds allow upgrade the turbo and go up in power.
Then you'll need an 80 tranny, etc and all the goodies.
If I can help with your build call or pm.
Me.
Rick
